Another way round to check a package  including Apache  installed version on Debian-based system  we can use   apt-cache policy  lt package name gt    e g  for Apache  apt-cache policy apache2   which will show something like  look at the Installed line      apt-cache policy apache2 apache2    Installed   none    Candidate  2 2 22-1ubuntu1 9   Version table       2 2 22-1ubuntu1 9 0         500 http   hk archive ubuntu com ubuntu  precise-updates main amd64 Packages         500 http   security ubuntu com ubuntu  precise-security main amd64 Packages      2 2 22-1ubuntu1 0         500 http   hk archive ubuntu com ubuntu  precise main amd64 Packages

You should use apache2ctl -v or apache2 -v for newer Debian or Ubuntu distributions   apache  etc apache2  apache2ctl -v Server version  Apache 2 2 16  Debian  Server built    May 12 2011 11 58 18   or you can use apache2 -V to get more information   apache2 -V Server version  Apache 2 2 16  Debian  Server built    May 12 2011 11 58 18 Server s Module Magic Number  x Server loaded   APR 1 4 2  APR-Util 1 3 9 Compiled using  APR 1 2 12  APR-Util 1 3 9 Architecture    64-bit Server MPM      Worker   threaded      yes  fixed thread count      forked      yes  variable process count  Server compiled with

The command varies depending on how your version of Linux has named the Apache Server   On Debian and Mac OS   apachectl -v   On Red Hat and Amazon s EC2 Linux use   httpd -v   On other verisons of Linux try   apache2 -v   You can use two different flags   -v   gives you the version number -V   gives you the compile settings including version number    If you want to run the command with the full directory like user3786265 did but don t know where your apache is located  use the whereis command   whereis httpd

Surely typing  usr sbin apache2 -v into the shell is the best and quickest way to go  by the way here s another option  just in case there s PHP too in your server and you re interested into gathering Apache version  and much more infos  in quick programmatical steps   Just make an info php file in your Apache web root folder  or whatever you like   and write these inside it    lt  php     phpinfo      gt    Now go to yoursite com info php  or localhost info php for local machines    You ll see your Apache version in PHP Variables section  here s an example   phpinfo   example dump page  Also  please notice that these steps obviously apply to any web server with PHP integration  so it s not limited to Apache and once created that page could be handy while developing  just don t forget to remove it on production environments

Some installations of Apache are fubar  think Oracle s packaging of it  OHS  and do not understand the -V flag  nor can be invoked directly without running into missing library errors   Easiest way is to use the strings command  part of binutils  on the httpd binary and grep for a string that might resemble a version  For example  assuming your httpd binary is under directory  foo bar     strings  foo bar httpd    grep 2 2 GLIBC 2 2 5 Oracle-HTTP-Server 2 2 22  Unix  Success Accepted 202 202 Accepted   Most binaries  not all  contain their version  at least their major version  as static strings  This is my go-to way to get versions  or to corroborate what a binary s help message matches what reality on the ground truly is
