Following are the steps to install eAccelerator:
step 1: Download from https://eaccelerator.net/ and install.
Compiling eAccelerator: You need to run these commands in the eAccelerator source directory. eAccelerator supports multiple php branches so you need to bootstrap eAccelerator first. This can be done with the phpize script. It very important that you use the phpize script of the php version for which you want to compile eAccelerator. The phpize and php-config scripts are available in the development packages of your distro. For fedora this is php-devel, for debian php-dev, other distribution should be similar.
When you have only one php install, it’s safe to run these commands in the source directory:
The phpize and php-config are the ones that are in your path. When you have more then one php install or the phpize and php-config scripts aren’t in your path then you should follow this procedure. This example has php installed in /opt/php, this is the path of the –prefix option given to the php configuration script.
./configure –enable-eaccelerator=shared –with-php-config=$PHP_PREFIX/bin/php-config
Step 2. Installing eAccelerator :
This will copy the previously created eAccelerator binary to the php extension directory. When this command ends, it will print out the directory in which eAccelerator has been installed.
