CentOS

Hello, I have server centos 6.4 apache 2.2.15. I have to switch apache to https, but nothing I found in the network does not work. I need help.

What have you tried? I assume you have aquired a certificate?
And you really, really should upgrade to CentOS 6.9.

6.4 is ancient and needs updating to 6.9+ - currently you are missing more than 5 years of fixes, security and otherwise.

You'll need to install the mod_ssl package and then configure it.
