Can anyone help me with Installation of solr and configuring it to mysql table.I Have tried almost all tutorials , i tried with Jetty , also tomcat.Still getting errors like Data Handler not defined or could not find solr.It's been a week , i am trying all day
In order to get solr running, (assuming that you've downloaded solr and extract it to a location), just navigate to the jetty folder.
Under that there should be a start.jar.
Just type in java -jar start.jar - this should start Solr under jetty. As simple as that. For all my development purposes, I use this. I wouldn't worry about Tomcat unless the app is ready to be deployed to some server.
In order to get your SOLR instance to pull data from mysql, you need the DataImportHandler configured. This documentation describes it well.
EDIT:
A google search for "solr mysql import" lead me here. It is exactly what you're after, I suppose.
I also had the same issue and it is not easy to find simple tutorial for this. Anyway I found following tutorial and it was useful for me.

Hi Please take a look here.
https://github.com/vikash32/indexing-mysql-table-into-solr
i have tried to make it less messy.
Step1:
Login to Linux and go to root folder opt ie cd /opt/
Step2:
Dowload Solr-6.6.2 from the solr link and use the below command to download solr in linux
Sudo wget http://www-us.apache.org/dist/lucene/solr/6.6.2/solr-6.6.2.tgz
Step3:
Extract the service installation file
Sudo tar xzf solr-6.6.2.tgz solr-6.6.2/bin/install_solr_service.sh --strip-components=2
Step4:
Install solr as a service using the script
sudo bash ./install_solr_service.sh solr-6.6.2.tgz
Step5:To check solr server status
sudo service solr status
Step6:To Start Solr in Cloud mode in RHEL
Go to root directory ie cd /opt/
Then go to solr directory cd /solr
Opt/solr > sudo ./bin/solr start -c -force -s server/solr -p 8983 -z zk1:2181,zk2:2181,zk3:2181
Zk1 is the hostname or ipaddress
Step7: To Create Core on solr
Go to solr directory ie cd /opt/solr
Opt/solr > sudo ./bin/sor/create -c -p 8983,7574 -s 2 -rf 2
-s stands for no of shards
-rf stands for no of replica

I want to run static website inside a docker container.
For this i have create ubuntu EC2 machine,installed docker and pulled centos image.
docker pull centos
docker run -td 9f38484d220f bash
docker exec -it aa779e39eb0f bash
===>now inside the container i am using below command
yum update
yum install apache
service httpd start
but i am getting command not recognized error.
Please help me figure out what i am doing wrong.
Also i as i want to run static website i will be putting below code once apache is installed successfully
$touch /var/www/html/index.html
$chkconfig httpd on
$echo "<b>Hii this is my first conatiner running/b>"
>> /var/www/html/index.html
Is this correct way of doing it ?
You installed apache and you are trying to run httpd. Refer this to read the difference between apache2 and httpd. You can run following commands to install apache and run a static hello world page on local host.
$ sudo yum update -y
$ sudo yum install -y httpd
$ sudo service httpd start
$ echo "<html><h1>Hello World!</h1></html>" > test
$ cat test > /var/www/html/index.html
You don't need a container for hosting a static website. S3 is a better choice for this.
If you want to do it as an exercice, considere this simple nginx solution, see: https://hub.docker.com/_/nginx
You have an example in the section : Hosting some simple static content
FROM nginx:alpine
COPY . /usr/share/nginx/html
Remember that you usually don't start a container then start a service inside (for testing and debugging). Entrypoint and command are what start your service, aka what you would manually do.
I have xmpp server (openfire_3.9.3) that is running on my ubuntu Ubuntu 14.04.1 LTS.
I have installed openfire by following given steps
1. $ sudo tar -zxvf openfire_x_x_x.tar.gz
2. $ sudo mv openfire /opt
then I moved to openfire bin directory to start openfire as
$ cd /opt/openfire/bin
$ sudo ./openfire start
then during setup through admin console always I am getting the given error
Home not found. Define system property "openfireHome" or create and add the openfire_init.xml file to the classpath
where I need to set openfireHome ? or how can i fixed it out ?
Well it seems your user account might have permissions issue. Can't you keep openfire in your home and try to run it from there and share results?
For me, it's a permissions issue.
I'm using server(Openfire 4.7.0, build e020f58) on my local computer (macOS Monterey 12.1 (21C52)).
My SOLUTION is:
sudo chmod -R 777 /usr/local/openfire
i'm trying to deploy my JSF site in EC2 instances, i'm new with cloud computing.
How do i install the GassFish 3 OpenSource in my EC2 instance ?
Update:
To download use 'curl' command :
curl http://www.java.net/download/jdk6/6u27/promoted/b03/binaries/jdk-6u27-ea-bin-b03-linux-i586-27_may_2011-rpm.bin > java-rpm.bin
or using wget:
wget http://www.java.net/download/jdk6/6u27/promoted/b03/binaries/jdk-6u27-ea-bin-b03-linux-i586-27_may_2011-rpm.bin
Here is what you need to do:
Get an AMI instance launched. Follow this tutorial to install. (Unfortunately, Glassfish installation tutorials are given as YouTube video on their official website!) The Simplest is to start with an existing EBS backed instance. This is how I started.
Now, if you want to kill the instance, it's same as throwing machine out of window. If you want to reuse it later or probably want to make a blue print for many instances that you will be launching in future. You need to bundle it up and register as an image.
If you have EBS backed instance, creating an image out of it is easier than sending an email. All you need to do is to login to your AWS Web Console, select the instance that you wanted to create an AMI of, select Instance Actions > Create Image from menu. Done!
If you have instance storage based AMI. You need to bundle up, and store in your S3 bucket, and register the AMI using, ec2-api-tools and ec2-ami-tools. So, have them installed in your instance and create the image as very neatly explained here.
Now, as far as cost is concerned, refer this. As far as I understand (my clients pay, so I don't really know how much) your running instance is going to cost you some money, even if there is no activity. However, if you make an AMI and store in S3 or in a EBS volume, you will be paying for storage cost.
Hope this explains what you wanted.
First you need to install jdk and then set environment variable JAVA_HOME.
Then follow below commands (Applicable on Amazon Linux EC2 ):

I'm trying to get started on libvirt with VirtualBox as a virtualization solution. I installed everything and VirtualBox itself is running when using their VBoxHeadless command.
However, libvirt fails to connect to VirtualBox:
# virsh -c vbox:///session
libvir: error : could not connect to vbox:///session
error: failed to connect to the hypervisor
I could not find any hints in the libvirt documentation that point to whether I have to make any domain specific configuration before using virsh.
Does anyone have a hint? Or even better, maybe a tutorial that works through the way of using libvirt, virsh or it's APIs (my later goal) from the ground up.
If you are doing this on Ubuntu, then the problem is their libvirt package is built without VirtualBox support.
You can rebuild the package with support very easily. Something like:
apt-get source -d libvirt
sudo apt-get build-dep libvirt
dpkg-source -x libvirt*dsc
Go into the libvirt directory and edit debian/rules so that instead of --without-vbox it says --with-vbox. You can add an entry to the top of debian/changelog so the package is compiled as a different version (e.g., append ~local1 to the version).
dpkg-buildpackage -us -uc -b -rfakeroot
You'll get new .debs built in the directory above. Use dpkg -i to install the relevant ones (libvirt0, libvirt0-bin, and whatever else you want).
Double-check whether or not you have write access to /var/run/libvirt/libvirt-sock.
The socket file should have permissions similar to:
$ sudo ls -la /var/run/libvirt/libvirt-sock
srwxrwx--- 1 root libvirtd 0 2010-08-24 14:54 /var/run/libvirt/libvirt-sock
I think it could be helpful also to increase the libvirt logging capabilities by running this in your shell:
export LIBVIRT_DEBUG=1
There is Ubuntu PPA for libvirt with VirtualBox support: https://launchpad.net/~cxl/+archive/ubuntu/libvirt
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.

Latest update for CentOS:
sudo yum install -y libpng libjpeg openssl icu libX11 libXext libXrender xorg-x11-fonts-Type1 xorg-x11-fonts-75dpi
wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.4/wkhtmltox-0.12.4_linux-generic-amd64.tar.xz
tar -xvf wkhtmltox-0.12.4_linux-generic-amd64.tar
sudo mv wkhtmltox/bin/* /usr/local/bin/
check installation success: wkhtmltopdf -V
rm -rf wkhtmltox
rm -f wkhtmltox-0.12.4_linux-generic-amd64.tar
Place the wkhtmltopdf executable on the server and chmod it +x.
Create an executable shell script wrap.sh containing:
#!/bin/sh
export HOME="$PWD"
export LD_LIBRARY_PATH="$PWD/lib/"
exec $# 2>/dev/null
#exec $# 2>&1 # debug mode
Download needed shared objects for that architecture and place them an a folder named "lib":
lib/libfontconfig.so.1
lib/libfontconfig.so.1.3.0
lib/libfreetype.so.6
lib/libfreetype.so.6.3.18
lib/libX11.so.6 lib/libX11.so.6.2.0
lib/libXau.so.6 lib/libXau.so.6.0.0
lib/libxcb.so.1 lib/libxcb.so.1.0.0
lib/libxcb-xlib.so.0
lib/libxcb-xlib.so.0.0.0
lib/libXdmcp.so.6
lib/libXdmcp.so.6.0.0
lib/libXext.so.6 lib/libXext.so.6.4.0
(some of them are symlinks)
… and you're ready to go:
./wrap.sh ./wkhtmltopdf-amd64 --page-size A4 --disable-internal-links --disable-external-links "http://www.example.site/" out.pdf
If you experience font problems like squares for all the characters, define TrueType fonts explicitly:
#font-face {
font-family:Trebuchet MS;
font-style:normal;
font-weight:normal;
src:url("http://www.yourserver.tld/fonts/Trebuchet_MS.ttf");
format(TrueType);
}
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.
# Install dependencies
apt-get install libfontconfig \
zlib1g \
libfreetype6 \
libxrender1 \
libxext6 \
libx11-6
# TEMPORARY FIX! SEE: https://github.com/wkhtmltopdf/wkhtmltopdf/issues/3001
apt-get install libssl1.0.0=1.0.2g-1ubuntu4.8
apt-get install libssl-dev=1.0.2g-1ubuntu4.8
# 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.
