I am using ubuntu 12.041 and installed apache through apt-get.
I don't know what version of mod_wsgi i am using albeit I google about it.
All I found is you can use apachctl to restart you apache and you would get
something like "Apache/2.2.2 (Unix) mod_wsgi/1.0 Python/2.3 configured". But
this's not happened to me.
Is there any way to know what version I am using ? Thanks.
If you restart Apache and inspect the log:
sudo apachectl -k restart
tail -n 5 /var/log/apache2/error.log
... you should see the version:
[Fri Jun 05 15:13:46.546029 2015] [mpm_prefork:notice] [pid 2245]
AH00163: Apache/2.4.7 (Ubuntu) PHP/5.5.9-1ubuntu4.9 mod_wsgi/3.4
Python/3.4.0 configured -- resuming normal operations
I use this
dpkg -l | grep wsgi
I don't know what it is doing, but it is a version?
As an aside that is probably not right, the version i have -
libapache2-mod-wsgi (on ubuntu 10.04)
is not python 3.x compliant. How I know that is a mystery - some random web forum. Also, how you'd actually work out which version is in the libapache2 version is beyond my ken.
But, ah, that unix script above will get the version for you. You're on your own after that, sailor.
In your WSGI application look at the value of mod_wsgi.version in the WSGI environ dictionary. That or import mod_wsgi module in a WSGI application running under mod_wsgi (not command line Python) and print out mod_wsgi.version from that module.
move to apache modules directory where mod_wsgi.so is.
run the following commands.
$ strings mod_wsgi.so | grep -w -A 1 "wsgi_init"
wsgi_init
4.5.7
Note it may be necessary to use -A with more than 1 line displayed after the occurrence of wsgi_init. For example with mod_wsgi version 2.7.5 you need -A 2 to see the version number:
$ strings mod_wsgi.so | grep -w -A 2 "wsgi_init"
wsgi_init
mod_wsgi/%s
2.7.5
A side question was about the version of Python used by mod_wsgi. For that just inspect mod_wsgi.so modules with ldd:
➜ / cd usr/lib/apache2/modules
➜ modules ldd mod_wsgi.so
linux-vdso.so.1 => (0x00007ffcaabf3000)
libpython2.7.so.1.0 => /usr/lib/x86_64-linux-gnu/libpython2.7.so.1.0 (0x00007f4e29c62000)

libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f4e28d51000)
/lib64/ld-linux-x86-64.so.2 (0x00007f4e2a423000)
➜ modules
In my case, it is clearly compiled with python2.7.
This is very old but I'm not seeing the answer i found so:
yum list installed '*mod_wsgi*'
or better yet
yum list '*mod_wsgi*'
to see what you have installed as well as available (perhaps) later versions.

I'm trying to upgrade to Apache 2.4.27, from 2.4.26. The configure, make & make install all complete, but when I try to bounce Apache, I get the following:
httpd: Syntax error on line 145 of /usr/local/apache2/conf/httpd.conf: Cannot load modules/mod_ssl.so into server: /usr/local/apache2/modules/mod_ssl.so: undefined symbol: SSL_get_srp_userinfo
OpenSSL version is openssl-1.0.2l, installed by running:
./config --prefix=/usr/local/ --openssldir=/usr/local/openssl enable-tlsext shared
make && make install
Apache 2.4.27 was installed by running:
./configure --enable-modules=all --enable-ssl --with-included-apr --enable-mod-proxy --with-included-apr-util
make && make install
I've had the same problem several times before, and the answer was to make sure LD_LIBRARY_PATH was set to /usr/local/lib64:/usr/local/lib however that isn't helping this time. I've tried configuring & compiling with this set, and with no LD_LIBRARY_PATH, neither helped.
mod_ssl.so looks like it's getting compiled against the yum installed version of OpenSSL:
[root#localhost httpd-2.4.27]# yum list installed |grep -i ssl
openssl.i686 1.0.1e-57.el6 #ol6_latest
openssl.x86_64 1.0.1e-57.el6 #ol6_latest
openssl-devel.x86_64 1.0.1e-57.el6 #ol6_latest

libcrypto.so.10 => /usr/lib64/libcrypto.so.10 (0x00007f3258bd1000)
I've tried plenty of different options (way too many to list here), such as --with-ssl=/usr/local/openssl, --enable-ssl=shared as well as setting LDFLAGS="-L/usr/local/lib64" in config.nice but still no joy.
Any ideas?
Finally managed to solve this from a comment at https://serverfault.com/questions/587267/upgrade-to-apache-2-4-9-opensssl-error-ssl-get-srp-userinfo. Turns out setting LDFLAGS was the answer:
LDFLAGS="-L/usr/local/lib64"; export LDFLAGS
"./configure" \
"--enable-so" \
"--with-included-apr" \
"--enable-ssl" \
"--with-ssl=/usr/local/openssl" \
"LDFLAGS=-L/usr/local/lib64" \
"$#"
I tried ,but didn't work for me.

The easiest way is to install the SCL version, as described here:
https://unix.stackexchange.com/questions/412122/how-to-update-apache-to-2-4-29-using-scl
My company's website is on an EC2 instance. The os is ubuntu 10.04. Currently we are using packages installed through apt-get. We have apache 2.2.14 and openssl 0.9.8k. After some security audit, I was told to update the version of openssl. The latest version of openssl on the 0.9.8 line is 0.9.8y. Is it compatible with apache 2.2.14 ? If so, Is it easy or at least possible to upgrade the openssl only ? I read it on somewhere that some people simply recommend to upgrade the whole os. Any comments ?
I did try to upgrade by downloading the tarball of
httpd-2.2.24 + openssl 0.9.8y
I installed them both under
/usr/local/apache2
/usr/local/ssl
I configured apache by
./configure --enable-modules=all --enable-mods-shared="all ssl" \
--with-ssl=/usr/local/ssl/ --enable-ssl
the /usr/local/ssl/bin/openssl does show 0.9.8y
but my web service shows apache 2.2.24 + openssl 0.9.8k
Any idea how to fix it ? Thanks.
$ ldd /usr/local/apache2/bin/httpd
...
libssl.so.0.9.8 => /lib/libssl.so.0.9.8
libcrypto.so.0.9.8 => /lib/libcrypto.so.0.9.8
...
The libssl.so.0.9.8 is still found in /lib/ system directory by the loader, not /usr/local/ssl. So you need to set LD_LIBRARY_PATH before running httpd:
$ export LD_LIBRARY_PATH=/usr/local/ssl/lib && /usr/local/apache2/bin/httpd
See also this document for more info on compatibility between apache & openssl. See this table for info on binary compatibility of openssl 0.9.8k and 0.9.8y.
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 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
tar -xvzf httpd-2.4.1.tar.gz
cd httpd-2.4.1
./configure --enable-file-cache --enable-cache --enable-disk-cache --enable-mem-cache --enable-deflate --enable-expires --enable-headers --enable-usertrack --enable-ssl --enable-cgi --enable-vhost-alias --enable-rewrite --enable-so --with-apr=/usr/local/apr/
make
make install
cd ..
You can find more about it below
Source: VaporCreations.com
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
Does anyone know the command to determine if OpenSSL and mod_ssl are installed on Apache2?
If you have PHP installed on your server, you can create a php file, let's called it phpinfo.php and add this <?php echo phpinfo();?>, and open the file in your browser, this shows information about your system environment, to quickly find info about your Apache loaded modules, locate 'Loaded Modules' on the resulting page.
If you have PHP installed on your server, you can chek it in runtime using "extension_loaded" funciontion. Just like this:
<?php
if (!extension_loaded('openssl')) {
// no openssl extension loaded.
}
?>
Usually, when you compile your apache2 server (or install it by packages facility stuff), you can check any directive that're available to be used by tapping this command:
~# $(which httpd) -L | grep SSL # on RHEL/CentOS/Fedora
~# $(which apache2) -L | grep SSL # on Ubuntu/Debian
~# $(which httpd2) -L | grep SSL # on SUSE
If you don't see any SSL* directive, it means that you don't have apache2 with mod_ssl compiled.
The default Apache install is configured to send this information on the Server header line. You can view this for any server using the curl command.
$ curl --head http://localhost/
HTTP/1.1 200 OK
Date: Fri, 04 Sep 2009 08:14:03 GMT
Server: Apache/2.2.8 (Unix) mod_ssl/2.2.8 OpenSSL/0.9.8a DAV/2 PHP/5.2.6 SVN/1.5.4 proxy_html/3.0.0
Use the following commands.
$ openssl version
OpenSSL 1.0.1e-fips 11 Feb 2013 (or similar output)
For RHEL/CentOS/Fedora:
$ httpd -t -D DUMP_MODULES | grep ssl
ssl_module (shared)
For Ubuntu/Debian
$ apache2 -t -D DUMP_MODULES | grep ssl
ssl_module (shared)
For SUSE
$ httpd2 -t -D DUMP_MODULES 2>&1 | grep ssl
ssl_module (shared)
Using Apache 2, you can see what modules are currently loaded by the HTTP daemon by running the following command:
apache2ctl -M
The -M option is really just a parameter passed to httpd.
apache2ctl is a front end to the Apache HyperText Transfer Protocol
(HTTP) server. It is
designed to help the administrator control the functioning of the Apache apache2 daemon.
NOTE: The default Debian configuration requires the environment variables APACHE_RUN_USER,
APACHE_RUN_GROUP, and APACHE_PID_FILE to be set in /etc/apache2/envvars.
The apache2ctl script returns a 0 exit value on success, and >0 if an error occurs. For
more details, view the comments in the script.
Fortunately, Most flavors of Linux have OpenSSL "out of the box".
To verify installation:
openssl version
Response:

Note: version OpenSSL 1.0.1 through 1.0.1f (inclusive)
are vulnerable to the OpenSSL Heartbleed Bug.
Versions 1.0.1g and greater are fixed.
For additional install info:
Ubuntu/Debian
dpkg -l | grep -i openssl

Yea, OpenSSL is installed!
To install OpenSSL if you don't have it, try:
Debian/Ubuntu:
sudo apt-get install openssl
RedHat/CentOS:
yum install openssl
To determine openssl & ssl_module
# rpm -qa | grep openssl
openssl-libs-1.0.1e-42.el7.9.x86_64
openssl-1.0.1e-42.el7.9.x86_64
openssl098e-0.9.8e-29.el7.centos.2.x86_64
openssl-devel-1.0.1e-42.el7.9.x86_64
mod_ssl
# httpd -M | grep ssl
or
# rpm -qa | grep ssl
You should install this Apache mod, http://httpd.apache.org/docs/2.0/mod/mod_info.html, it basically gives you a run down of the mods you're using and the Apache settings.
I have this enabled on my Apache and it gives me this info for my website,
Server Version: Apache/2.2.3 (Debian) mod_jk/1.2.18 PHP/5.2.0-8+etch13 mod_ssl/2.2.3 OpenSSL/0.9.8c mod_perl/2.0.2 Perl/v5.8.8
If you just run openssl in your terminal it should present the openSSL shell. My first clue to knowing that I didn't have mode_ssl was when I got the following error after adding SSLEngine on in my virtualhost file:
Invalid command 'SSLEngine', perhaps misspelled or defined by a module not included in the server configuration
In centos I just had to install it via yum install mod_ssl
Just look in the ssl_engine.log in your Apache log directory where you should find something like:
[ssl:info] [pid 5963:tid 139718276048640] AH01876: mod_ssl/2.4.9 compiled against Server: Apache/2.4.9, Library: OpenSSL/1.0.1h
Create a test.php file with the following code in a www folder:
<?php echo phpinfo();?>
When you navigate to that page/URL in the browser. You will see something similar if you have openssl enabled:
Enable mod_ssl in httpd.conf and restart the apache. You will see the openssl information in error.log as below
[Fri Mar 23 15:13:38.448268 2018] [mpm_worker:notice] [pid 8891:tid 1] AH00292: Apache/2.4.29 (Unix) OpenSSL/1.0.2n configured -- resuming normal operations
