I have a problem with this module.
In my local server i open my php.ini and i have the module imagick in the list.
Now i changed the site to a webserver, but in php.ini, the module is not showed.
I talked with the company that have the web server, and the answer is: "the module is installed and show me this:"
root#dime38 [~]# convert
Version: ImageMagick 6.2.8 08/25/10 Q16 file:/usr/share/ImageMagick-6.2.8/doc/index.html
but when i use this code:
<?php
$image = new Imagick();
$image->newImage(100, 100, new ImagickPixel('red'));
$image->setImageFormat('png');
header('Content-type: image/png');
echo $image;
?>
i simple receive this:
Fatal error: Class 'Imagick' not found in /home/empreg0l/public_html/modulo.php on line 3
But the same code works in my local host.
What is the problem? (Probably, the extension is commented in the php.ini? or exists any problem in the code?)
thanks
There is a difference between the ImageMagick binary (which can be called through the convert command) and the IMagick PHP extension. Even if the binary is installed, it doesn't mean the PHP extension is.
Your provider would have to explicitly activate that in their server's PHP.
If they won't do that, you'll have to recreate the IMagick commands as command line options and call it through exec().
To install imagick for php:
apt-get install php5-imagick
Use get_loaded_extensions to confirm you have the imagick PHP extension installed.
var_dump(get_loaded_extensions());
apt-get install pkg-config libmagickwand-dev -y
cd /tmp
wget https://pecl.php.net/get/imagick-3.4.0.tgz
tar xvzf imagick-3.4.0.tgz
cd imagick-3.4.0
phpize
./configure
make install
rm -rf /tmp/imagick-3.4.0*
echo extension=imagick.so >> /etc/php/7.0/cli/php.ini
echo extension=imagick.so >> /etc/php/7.0/fpm/php.ini

I just created a docker container and tried to install SQL Relay inside it.
I've checked the prerequisites here and followed the installation documents here.
However, at the end of make install of sqlrelay, I saw an error like this:
update-rc.d: /etc/init.d/sqlrelay: file does not exist
update-rc.d: /etc/init.d/sqlrcachemanager: file does not exist
make[1]: *** [install] Error 1
make[1]: Leaving directory `/sqlrelay-0.66.0/init'
make: *** [install-init] Error 2
What might be wrong with my installation?
Here's the docker file I used to start my installation:
FROM ubuntu:trusty
RUN apt-get update && \
apt-get install libxml2-dev libpcre3 libpcre3-dev libmysqld-dev -y
RUN apt-get install mysql-server libmysqlclient-dev -y
# sql relay prerequisites
RUN apt-get install g++ make perl php5-dev python-dev ruby-dev \
tcl-dev openjdk-7-jdk erlang-dev nodejs-dev node-gyp mono-devel \
libmariadbclient-dev libpq-dev firebird-dev libfbclient2 libsqlite3-dev \
unixodbc-dev freetds-dev mdbtools-dev -y
COPY rudiments-0.56.0.tar.gz /
COPY sqlrelay-0.66.0.tar.gz /
EXPOSE 80
Here are the outputs of ./configure, make, and make install inside sqlrelay-0.66.0 folder:
configure_log
make_log
make_install_log
If you need more information of my installation process, just let me know. I can provide it.
I think you should use ADD instead of COPY in your lines such as
COPY rudiments-0.56.0.tar.gz /
Your COPY just copies the .tar.gz, but does not unpack them
as with ADD
If the <src> parameter of ADD is an archive in a recognised compression format, it will be unpacked
This is extracted from
What is the difference between the `COPY` and `ADD` commands in a Dockerfile?
I have recently hit the same issue. The issue I found was that the init Makefile was incorrectly detecting the use of systemctl on Ubuntu Trusty and putting the scripts there. Later on the script would try to find the scripts in init.d and fail.
The solution is to edit the Makefile: sqlrelay-X.X.X/init/Makefile
Replace:
install:
if ( test -d "/lib/systemd/system" ); \
With:
install:
if ( test -d "/lib/systemd/system_x" ); \
Make a similar change to the uninstall option later in the script and it will now correctly install on Ubuntu.
I have just upgraded my Macbook Pro OS to El Capitan (v10.11.4).
My attempt to export a Markdown file (created using Sublime Text 2, v2.0.2, build 2221) to pdf using pandoc is now failing, and I receive the following error:
pandoc: xelatex not found. xelatex is needed for pdf output
My output command is as follows:
pandoc doc1.md -o doc1.pdf --toc -V geometry:margin=1in --variable fontsize=10pt --variable fontfamily=utopia --variable linkcolor=blue --latex-engine=xelatex -f markdown-implicit_figures -s
Above command worked like a charm prior to installing El Capitan.
FYI - in searching for questions here I have not found one that gives a suitable answer.
For my case, add one line into ~/.bashrc solved the error:
export PATH=/Library/TeX/texbin:$PATH
Of course, the environment variable should be activated in the current term:
$ . ~/.bashrc
then run: $ make
the error disappears.
El Capitan's security features disable and remove the old symlink /usr/texbin. If you have MacTeX 2015, they should've been installed in /Library/TeX/texbin as well. You'll have to update the PATH your using to launch pandoc to include that folder. If you have a pre-2015 distribution of MacTeX, there are instructions here.
Linux Ubuntu instructions:
Tested on Ubuntu 18.04:
If you see this error on Linux Ubuntu:
pandoc: xelatex not found. xelatex is needed for pdf output
Then you need to install the texlive-xetex package like this:
sudo apt update
sudo apt install texlive-xetex
That solves it! Source where I learned this: TEX: XeLatex under Ubuntu.
In my particular case, I was trying to run this make_book.sh script to generate book.pdf, so I needed to do all of the following:
sudo apt update
sudo apt install pandoc
pip3 install MarkdownPP
sudo apt install texlive-xetex
cd path/to/repo
cd systemd-by-example
./make_book.sh
# You'll now have "book.pdf" inside directory "systemd-by-example"!

I am trying to install Apache HTTP server locally in my box as a regular user (non-root).
I have downloaded Apache 2.4.1 version of Apache HTTP server [http://httpd.apache.org/download.cgi]. However when I am trying to build and install locally in my box I am getting below error:
httpd/httpd-2.4.1 1059> ./configure
checking for chosen layout... Apache
checking for working mkdir -p... yes
checking for grep that handles long lines and -e... /bin/grep
checking for egrep... /bin/grep -E
checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
checking target system type... x86_64-unknown-linux-gnu
Configuring Apache Portable Runtime library ...
checking for APR... no
configure: error: APR not found. Please read the documentation.
I am not sure what dependency it is looking for - I mean the download package does not contains it? What I need to do to build / deploy Apache HTTP server?
When it tells you Please read documentation it means that you should go read Apache documentation ( http://httpd.apache.org/docs/2.4/install.html ) which tells you to
download the latest versions of both APR and APR-Util from Apache APR,
unpack them into ./srclib/apr and ./srclib/apr-util (be sure the
domain names do not have version numbers; for example, the APR
distribution must be under ./srclib/apr/)
then do
./configure --with-included-apr
For Ubuntu 11.10 this option seems to be working well:
# APR
wget http://mirrors.axint.net/apache//apr/apr-1.4.6.tar.gz
tar -xvzf apr-1.4.6.tar.gz
cd apr-1.4.6/
./configure
make
make install
cd ..
# APR Utils
wget http://mirrors.axint.net/apache//apr/apr-util-1.4.1.tar.gz
tar -xvzf apr-util-1.4.1.tar.gz
cd apr-util-1.4.1
./configure --with-apr=/usr/local/apr
make
make install
cd ..
# Apache
wget http://apache.petsads.us//httpd/httpd-2.4.1.tar.gz

make

If you have Debian/Ubuntu you can just:
apt-get install libapr1-dev libaprutil1-dev
Then ./configure
Done
Here are the steps of how I installed apache-httpd on a non-root users:
Download and extract apache-httpd-2.4.2 (but before ./configuring,
making and installing it, follow the steps below:)
Download and extract APR & APR-UTIL into "./srclib/apr" &
"./srclib/apr-util" folders. This requires ./configure
--with-apr=./apache/httpd-2.4.2/srclib/apr (and) --with-included-apr (options).
Download, extract, ./configure (with) --prefix=localURL, make and
make install PCRE into "./pcre" folder. This requires ./configure
--with-pcre=/home/username/apache/pcre (option).
Configure apache-httpd by entring following command (I like to
enable certain options as written in the command below):
./configure --enable-file-cache --enable-cache --enable-disk-cache
--enable-mem-cache --enable-deflate --enable-expires --enable-headers --enable-usertrack --enable-cgi --enable-vhost-alias --enable-rewrite --enable-so --with-apr=/home/username/apache/httpd-2.4.2/srclib/apr --prefix=/home/username/apache/httpd-2.4.2/ --with-included-apr --with-pcre=/home/username/apache/pcre
Note: When configuring apache-httpd, use option "--enable-ssl" ONLY if OpenSSL is installed otherwise DON'T enable it.
Now on the command-line, enter 'make' and 'make install' command.
Open and configure the 'httpd.conf' file e.g.:
"vi /home/eddie_kumar/apache/httpd-2.4.2/conf/httpd.conf"
IMPORTANT: don't forget to change the default port from 80 to something else e.g. 8080, this is especially important for non-root
user. (How to? open httpd.conf -> search "Listen 80" -> change it
to "Listen 8080".
And that's it, now open your browser enter "localhost:8080", it should display "It works!".
If you are using fedora, you can use yum to install APR, APR-Util and PCRE. You'll also need to download apr-devel, apr-util-devel and pcre-devel.
That being said, you can just run the following command on your terminal and no more "configure: error: APR not found.. ..APR-Util and PCRE" errors.
yum -y install arp apr-devel apr-util apr-util-devel pcre pcre-devel
I'm using fedora 17 and planning on using a shell script to setup apache 2.4.3. So yum works pretty slick instead of manually downloading apr, apr-util, and pcre.
1, You need APR (apache portable runtime), which is core component of apache web server
2, If you wnat to do make install, you may need root account
3, Even if not, apache can not start to listen on unprivileged port (lower then 1024) without root account
4, gain root or ask someone with root to install apache from official repo(I don;t know which distro you run) like using yum, apt-get, etc...
Apr or pcre related errors require the source to be downloaded and Apache HTTPD "configure" process needs to be made aware of these source locations on your file system. For instance: if you downloaded the source for APR at ./srclib (relative to apache httpd) then you would use
--with-included-apr
as the configure option.
On the other hand if you want to not build but install APR / APR-UTIL, then you need the following on CentOS / RedHat:
yum install apr-util-devel apr-devel
However it might so happen that the APR version provided by yum does not match what is expected by this version of Apache httpd. In that case you could download APR and APR-UTIL and use the --with-included-apr option.
You could also build PCRE utilizing the same "configure, make, make install" process and then continue where you left off building Apache httpd.
Or you could install pcre:
yum install pcre-devel
If while building PCRE: you see "compile: unrecognized option" then perhaps you would need other dependencies as well: Please see the details at:
http://khanna111.com/wordPressBlog/2012/09/11/94087-2/
It also covers "mod_deflate" and "zlib" as well.

Installing and compiling the Apache server on Ubuntu machine
step 1:Install the Java JDK
sudo apt install openjdk-11-jdk
sudo gedit /etc/environment
JAVA_HOME="/usr/lib/jvm/openjdk-11"
source /etc/environment
echo $JAVA_HOME
verify the java version
javac --version
**** install Other required packages:**
sudo apt-get install apache2-dev -y
sudo apt-get install libpcre3 libpcre3-dev
Step 2 :To Install Apache HTTP Server
#1 For ubuntu ,install development tools including the C compiler:
sudo apt-get install build-essential checkinstall
#2 Download and Extract the required files
assuming that all the files have been downloaded into the ~/Downloads directory
Download the Apache HTTP Server httpd-2.4.41.tar.gz from Apache download page (https://httpd.apache.org/download.cgi)
and following required libraries for compiling the apache HTTP server:
apr-1.7.0.tar.gz(http://apr.apache.org/download.cgi)
apr-util-1.6.1.tar.gz(http://apr.apache.org/download.cgi)
pcre2-10.34.tar.gz (ftp://ftp.pcre.org/pub/pcre/) http://pcre.org/
****Read Requirements Section(http://httpd.apache.org/docs/2.4/install.html)***
#3 Extract the tar files
tar -xvf httpd-2.4.41.tar.gz
tar -xvf apr-1.7.0.tar.gz
tar -xvf apr-util-1.6.1.tar.gz
tar -xvf pcre2-10.34.tar.gz
after extraction you should see following list of directories in ~/Downloads
httpd-2.4.41
apr-1.7.0
apr-util-1.6.1
pcre2-10.34
#4 Create a directory for the apache HTTP Server
*make sure to give all rights to this directory so that while compiling files can be read/written
sudo mkdir /home{your username here}/apache
To give all permissions to a apache directory :
sudo chmod -R 777 /home{your username here}/apache
#5 copy the arp and arp-util directory into the ~/Downloads/httpd-2.4.41/srclib/
cd ~/Downloads
mv apr-util-1.6.1 ~/Downloads/httpd-2.4.41/srclib/apr-util
mv apr-1.7.0 ~/Downloads/httpd-2.4.41/srclib/apr
#6 Configure the sources for compilation.
The --prefix option can be used to install the Web server in a location where you can write files.
cd ~/Downloads/httpd-2.4.41/
./configure --prefix=/home/{username here}/apache --with-pcre=~/Downloads/pcre2-10.34
NOTE:
If you have some problems while running above command,you can also try
insallting pcre in /usr/local/pcre, using
./configure --prefix=/usr/local/pcre
make
sudo make install
commands and then by running folllowing commands:
cd ~/Downloads/httpd-2.4.41/
./configure --prefix=/home/{username here}/apache --with-pcre=/usr/local/pcre
make
sudo make install
If you still face some problems ,make sure that ~/apache and its nested directory have read/write permissions. if not run **sudo chmod -R 777 /home{your username here}/apache** command again.
#7 Compile Apache HTTP Server.
cd ~/Downloads/httpd-2.2.25
sudo make
#8 Install Apache HTTP Server.
cd ~/Downloads/httpd-2.2.25
sudo make install
Optional
#9 To Prepare Your Hosts File
sudo gedit /etc/hosts
27.0.0.1 localhost www.example.com
sudo gedit /home/{your username here}/apache/conf/httpd.conf
and copy:
Listen 8000
ServerName www.example.com:8000
#10 Test the installation to ensure Apache HTTP Server is working.
/home/{your username here}//apache/bin/apachectl -k start
I installed memcache in the following way:
1) yum install memcached
2) yum install php-pecl-memcached
3) Also enabled the 'memcached.so' in php.ini
I tested the memcached in the follwing way:
$mc = new Memcache;
$mc->addServer('localhost', 11211);
echo "Server's version: " . $mc->getVersion() ;
But it generates the following error:
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/memcached.so' - /usr/lib64/php/modules/memcached.so: undefined symbol: php_json_encode in Unknown on line 0
PHP Fatal error: Class 'Memcache' not found in /root/memcacheTest.php on line 2
Thank u.
I don't know PHP well (or at all), but from the error message I'll hazzard a guess that you do not have the PHP JSON extension installed, which is apparently needed by the memchached extension.
Apparently, the JSON extension has been in PHP since version 5.2.0, therefore:
You have an older version and you need to upgrade or install the JSON extension yourself
or
Your operating system distributor supplies the PHP JSON extension in a different package that you have not installed.
There is of course the possibility of a misconfiguration, but I think it's slightly less likely.
This showed memcached.so didn't loaded successfully.
Error shows the reason: json.so should be load before memcached.so
Please use php -m | grep memcached to check whether memcached.so is loaded successfully.
If show memcached, this mean it succeeded.
If show like PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/memcached.so' - /usr/lib64/php/modules/memcached.so: undefined symbol: php_json_decode_ex in Unknown on line 0
Here is the solusion:
e.g your php.ini is /etc/php.ini, your php.d is /etc/php.d/
Solution 1
comment 'memcached.so' in php.ini
vim /etc/php.d/memcached.ini
add extension=memcached.so in /memcached.ini
php -m | grep memcached check whether memcached is succeed loaded
Solution 2
rm /etc/php.d/json.ini
add extension=json.so in php.in before extension=memcached.so
php -m | grep memcached check whether memcached is succeed loaded
Can you check and double check user permissions? Additionally, my experience with PHP is that the distribution repository versions of PHP aren't very good. I solved those symbol errors by compiling PHP from the ground up. But that's a very radical and time-consuming solution.
http://pecl.php.net/bugs/bug.php?id=17574&edit=1
Just make sure that extension=json.so is specified BEFORE
extension=memcached.so.
I had placed extension=memcached.so in php.ini, and extension=json.so
was specified in /etc/php.d/json.ini, that is parsed AFTER php.ini.
That is why PHP can't find php_json_encode() at the point of loading
memcached.so.
Also, check that the permissions on memcached.so are the same as the other extensions
Try to install the version 2.0. It helped for me.
yum -y install gcc-c++
wget http://launchpad.net/libmemcached/1.0/0.50/+download/libmemcached-0.50.tar.gz

I have tried in all ways to get wkhtmltopdf installed on our web server but unfortunately it is not getting installed. I cannot access user/bin folder as stated in a tutorial on installation.
On the server in public_html folder there is a sub folder _vti_bin, I copied the file wkhtmltopdf-i386 from wkhtmltopdf-0.9.1-static-i386, but I am not able to execute it.
How to install wkhtmltopdf on (shared hosting) web server and get it working?
I've managed to successfully install wkhtmltopdf-amd64 on my shared hosting account without root access.
Here's what i did:
Downloaded the relevant static binary v0.10.0 from here: http://code.google.com/p/wkhtmltopdf/downloads/list
EDIT: The above has moved to here
via ssh on my shared host typed the following:
$ wget {relavant url to binary from link above}
$ tar -xvf {filename of above wget'd file}
you'll then have the binary on your host and will be able to run it regardless of if its in the /usr/bin/ folder or not. (or at least i was able to)
To test:
$ ./wkhtmltopdf-amd64 http://www.example.com example.pdf
Note remember that if you're in the folder in which the executable is, you should probably preface it with ./ just to be sure.
Worked for me anyway
If you have sudo access...
Ubuntu 14.04 / 15.04 / 18.04:
sudo apt-get install wkhtmltopdf
# or
sudo apt install wkhtmltopdf
Others
Look at the other answers.
If its ubuntu then go ahead with this, already tested.:--
first, installing dependencies
sudo aptitude install openssl build-essential xorg libssl-dev
for 64bits OS
wget http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.9.9-static-amd64.tar.bz2
tar xvjf wkhtmltopdf-0.9.9-static-amd64.tar.bz2
mv wkhtmltopdf-amd64 /usr/local/bin/wkhtmltopdf
chmod +x /usr/local/bin/wkhtmltopdf
for 32bits OS
wget http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.9.9-static-i386.tar.bz2
tar xvjf wkhtmltopdf-0.9.9-static-i386.tar.bz2
mv wkhtmltopdf-i386 /usr/local/bin/wkhtmltopdf
chmod +x /usr/local/bin/wkhtmltopdf
Debian 8 Jessie
This works
sudo apt-get install wkhtmltopdf
Chances are that without full access to this server (due to being a hosted account) you are going to have problems. I would go so far as to say that I think it is a fruitless endeavor--they have to lock servers down in hosted environments for good reason.
Call your hosting company and make the request to them to install it, but don't expect a good response--they typically won't install very custom items for single users unless there is a really good reason (bug fixes for example).
Lastly, depending on how familiar you are with server administration and what you are paying for server hosting now consider something like http://www.slicehost.com. $20 a month will get you a low grade web server (256 ram) and you can install anything you want. However, if you are running multiple sites or have heavy load the cost will go up as you need larger servers.

List of stable versions wkhtmltopdf: http://wkhtmltopdf.org/downloads.html
Installing wkhtmltopdf on Debian 8.2 (jessie) x64:
sudo apt-get install xfonts-75dpi
sudo apt-get install xfonts-base
sudo wget http://download.gna.org/wkhtmltopdf/0.12/0.12.2.1/wkhtmltox-0.12.2.1_linux-jessie-amd64.deb
sudo dpkg -i wkhtmltox-0.12.2.1_linux-jessie-amd64.deb
Shared hosting no ssh or shell access?
Here is how i did it;
Visit https://wkhtmltopdf.org/downloads.html and download the appropriate stable release for Linux. For my case I chose 32-bit
which is wkhtmltox-0.12.4_linux-generic-i386.tar.xz
Unzip to a folder on your local drive.
Upload the folder to public_html (or whichever location fits your need) using an FTP program just like any other file(s)
Change the binary paths in snappy.php file to point the appropriate files in the folder you just uploaded.
Bingo! there you have it. You should be able to generate PDF files.
A few things have changed since the top answers were added. They used to work out for me, but not quite anymore, so I have been hacking around for a bit and came up with the following solution for Ubuntu 16.04. For Ubuntu 14.04, see the comment at the bottom of the answer. Apologies if this doesn't work for shared hosting, but it seems like this is the goto answer for wkhtmltopdf installation instructions in general.

# Download, extract and move binary in place
curl -L -o wkhtmltopdf.tar.xz https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.4/wkhtmltox-0.12.4_linux-generic-amd64.tar.xz
tar -xf wkhtmltopdf.tar.xz
mv wkhtmltox/bin/wkhtmltopdf /usr/local/bin/wkhtmltopdf
chmod +x /usr/local/bin/wkhtmltopdf
Test it out:
wkhtmltopdf http://www.google.com google.pdf
You should now have a file named google.pdf in the current working directory.
This approach downloads the binary from the website, meaning that you can use the latest version instead of relying on package managers to be updated.
Note that as of today, my solution includes a temporary fix to this bug. I realize that the solution is really not great, but hopefully it can be removed soon. Be sure to check the status of the linked GitHub issue to see if the fix is still necessary when you read this answer!
For Ubuntu 14.04, you will need to downgrade to a different version of libssl. You can find the versions here. Anyways, be sure to consider the implications of downgrading libssl before doing so on any production server.
I hope this helps someone!
After trying, below command work for me
cd ~
yum install -y xorg-x11-fonts-75dpi xorg-x11-fonts-Type1 openssl git-core fontconfig
wget https://downloads.wkhtmltopdf.org/0.12/0.12.4/wkhtmltox-0.12.4_linux-generic-amd64.tar.xz
tar xvf wkhtmltox-0.12.4_linux-generic-amd64.tar.xz
mv wkhtmltox/bin/wkhtmlto* /usr/bin
Version 12.5 of wkhtmltopdf only lists DEB files on their download page now. Being a mac user and not knowing much linux or what DEB files were I couldn't use the solutions posted.
This page helped me get past the knew twist of downloading a DEB file: http://www.g-loaded.eu/2008/01/28/how-to-extract-rpm-or-deb-packages/
Basically what I did was:
Downloaded from https://wkhtmltopdf.org/downloads.html
Unzipped the DEB file.
Unzipped data.tar.xz
Uploaded the binary in the unzipped 'usr' folder from step 3 (usr/local/bin/wkhtmltopdf)
Then I found out that the 'exec' function was disabled on my host. So make sure you can specifically run 'exec' if you're using PHP to run this. "Can I run the wkhtmltopdf binary" isn't specific enough. My fault.
