Upgrading Apache 2.2 to 2.4 on CentOS 6.x
 

-sh-4.1$ /usr/local/apache2/bin/apachectl -v
Server version: Apache/2.4.20 (Unix)
Server built: Apr 9 2018 13:16:08

-sh-4.1$ httpd -v
Server version: Apache/2.2.15 (Unix)
Server built: Aug 15 2017 19:44:58

-sh-4.1$ cat /etc/redhat-release
CentOS release 6.9 (Final)


All - As above mentioned details, CentOs 6.x doesn't support Http v2.4 and it needs to be installed through Apr/Apr-Util packages. I have both the http versions running. I would like to know how to make my existing application to use new version of apache ? If i stop older http version (2.2) , "httpd -v" command won't work but i need to use "apachectl -v". Kindly advise.

Hi and welcome to LQ,

If you have installed apache under /usr/local/apache2, and you want to use that instead of the one that came with your distro, you need to disable the latter from starting on boot.
For this run, as root:
Then you can add in /etc/rc.local the following:
If you want to be more productive, you can edit the original /etc/init.d/httpd startup script and add your apache installation as the httpd service, instead of the original httpd.

Hi Bathory - Would you let me know in detail on above ?

I want to print version 2.4 on httpd command.

apachectl=/usr/sbin/apachectl
httpd=${HTTPD-/usr/sbin/httpd}
prog=httpd


Above are the line in /etc/init.d/httpd script. If i change as below, will it work ?

apachectl=/usr/sbin/apachectl
httpd=$apachectl
prog=httpd

If you want to print the 2.4.x version, you need to add the path to the httpd executable before anything else in your PATH env. variable. For the bash shell, run:
To make this permanent, see this



This is the httpd service startup script. If you want to use it, you need to edit it (make a backup first) and change the location of the various files mentioned there accordingly.

Awesome Bathory !

It worked

-sh-4.1$ httpd -v
Server version: Apache/2.4.20 (Unix)

Cool.!
Now that it worked, consider updating it to the latest version (2.4.33) for security reasons.

Regards
