You can install APC (Alternative PHP Cache) in your cpanel server using the following steps:
# pecl install apc
Then add the extension in the php.ini file.
You can get the php.ini file by
# php –ini
Add the following line to it.
Then, retart apache service and you are good to go.
I encountered the following error while installation.
“checking whether the C compiler works… configure: error: cannot run C compiled programs.”
I made it working by the following:
# mount -o remount,exec,suid /tmp
Complete the installation and don’t forget to remount the tmp directory with noexec, nosuid options after the installation.
