With a web server software as old as Apache<\/a>, there tend to be situations where your installation falls behind current versions if not maintained properly. That is why you need to know how to check Apache version on Ubuntu.<\/p>\n\n\n\n

Apache, free and open-source software is the most popular web server today. It was initially released in April 1995. The current stable release as of posting this article is Apache 2.4.51<\/a>.<\/p>\n\n\n\n

Written in C, it is a cross-platform web<\/a> server and supports the major operating systems Linux, macOS, and Windows among a host of others.<\/p>\n\n\n\n

Check Apache Version Using This<\/h2>\n\n\n\n

You should use the apache2 -v command-line option (in lower case) to check the current Apache version on Ubuntu<\/a>. This command also works on other Debian<\/a>-based Linux<\/a> systems.<\/p>\n\n\n\n

$ apache2 -v<\/code><\/pre>\n\n\n\n

With the following as output.<\/p>\n\n\n\n

Server version: Apache\/2.4.51 (Ubuntu)\nServer built: 2021-10-07T19:17:14<\/code><\/pre>\n\n\n\n

This is not to be confused with the -V<\/code> option, that is -V<\/code> in upper case. The caps option is used to show compile settings and includes the version number too. You can check the output by running this command.<\/p>\n\n\n\n

$ apache2 -V<\/code><\/pre>\n\n\n\n

This is an example of the partial output.<\/p>\n\n\n\n

...\n\nServer built: 2021-10-07T19:17:14\nServer's Module Magic Number: 20120211:118\nServer loaded: APR 1.7.0, APR-UTIL 1.6.1\nCompiled using: APR 1.7.0, APR-UTIL 1.6.1\nArchitecture: 64-bit\nServer MPM: event\nthreaded: yes (fixed thread count)\nforked: yes (variable process count)\nServer compiled with\u2026.\n\n...<\/code><\/pre>\n\n\n\n

You can check other Apache command-line options using this.<\/p>\n\n\n\n

$ apache2 -h<\/code><\/pre>\n\n\n\n

Which will give you the following output.<\/p>\n\n\n\n

Usage: apache2 [-D name] [-d directory] [-f file]\n               [-C "directive"] [-c "directive"]\n               [-k start|restart|graceful|graceful-stop|stop]\n               [-v] [-V] [-h] [-l] [-L] [-t] [-T] [-S] [-X]\nOptions:\n  -D name            : define a name for use in <IfDefine name> directives\n  -d directory       : specify an alternate initial ServerRoot\n  -f file            : specify an alternate ServerConfigFile\n  -C "directive"     : process directive before reading config files\n  -c "directive"     : process directive after reading config files\n  -e level           : show startup errors of level (see LogLevel)\n  -E file            : log startup errors to file\n  -v                 : show version number\n  -V                 : show compile settings\n  -h                 : list available command line options (this page)\n  -l                 : list compiled in modules\n  -L                 : list available configuration directives\n  -t -D DUMP_VHOSTS  : show parsed vhost settings\n  -t -D DUMP_RUN_CFG : show parsed run settings\n  -S                 : a synonym for -t -D DUMP_VHOSTS -D DUMP_RUN_CFG\n  -t -D DUMP_MODULES : show all loaded modules\n  -M                 : a synonym for -t -D DUMP_MODULES\n  -t -D DUMP_INCLUDES: show all included configuration files\n  -t                 : run syntax check for config files\n  -T                 : start without DocumentRoot(s) check\n  -X                 : debug mode (only one worker, do not detach)<\/code><\/pre>\n\n\n\n

Conclusion<\/h2>\n\n\n\n

For users on the CentOS, Fedora, and RHEL-based Linux systems, we have a related guide<\/a> showing you how you can do the above on those systems.<\/p>\n\n\n\n

Meanwhile, if you use Windows for your Apache needs we have you covered with this related guide<\/a>.<\/p>\n\n\n\n

Finally, in this beginner’s guide, you have seen how to use the command-line utility to check Apache version on Ubuntu and Debian-based systems. You have also learned how to access the Apache2 help interface for other options you may need in the future.<\/p>\n","protected":false},"excerpt":{"rendered":"
