How to install eAccelerator

Eaccelerator is a PHP accelerator/encoder/caching utility that is based 
off of the old mmcache (which is no longer being maintained).What Eaccelerator does is: it caches your PHP scripts so that the database is no longer being queried every time someone needs a script. This is 
particularly useful for large forums, but pretty much anyone can benefit 
from it. Since these scripts are cached, youll notice a decrease in 
memory use and server load. 
Now, onto installing this! 
============================ 
Installing Eaccelerator 
============================ 
1. First, youll want to SSH into your server as the root user. you should 
be in the default directory now. If youre not, type in cd ~ 
Now well make the eaccelerator directory: 
mkdir /ea/ 
cd /ea/ 
2. Now well grab the files, and untar them: 
Notice that its a tar.bz2 file, so we need to decompress it twice. 

wget http://oratoronline.com/how2/Eaccelerator/eaccelerator-0.9.5.2.tar.bz2 

bzip2 -d eaccelerator-0.9.4-rc1.tar.bz2 

tar -xvf eaccelerator-0.9.4-rc1.tar 

3. Now that we have done that, lets install Eaccelerator: 

Note: in the following export command, you need to point that to where 
PHP is installed. For most, its usually either /usr/ or /usr/local, but 
it may be something else. 

cd eaccelerator-0.9.4-rc1/ 

export PHP_PREFIX=/usr 

$PHP_PREFIX/bin/phpize 

./configure –enable-eaccelerator=shared –with-php-config=$PHP_PREFIX/bin/php-config 
make 
make install 

4. Its basically installed, now we need to edit the php.ini files to 
include Eaccelerator. This is usually found in the /etc/ folder, but if 
you cant find it, run a “locate php.ini (without quotes) to find it. 
You can use pico or vi, its your choice: 
cd ~ 
nano /etc/php.ini 
======================================= 
For a PHP extension install (most will probably want this) 
======================================= 
extension=eaccelerator.so 
eaccelerator.shm_size=16 
eaccelerator.cache_dir=/tmp/eaccelerator 
eaccelerator.enable=1 
eaccelerator.optimizer=1 
eaccelerator.check_mtime=1 
eaccelerator.debug=0 
eaccelerator.filter= 
eaccelerator.shm_max=0 
eaccelerator.shm_ttl=0 
eaccelerator.shm_prune_period=0 
eaccelerator.shm_only=0 
eaccelerator.compress=1 
eaccelerator.compress_level=9 
========================================================================== 
For a Zend Extension install (only if you have Zend Optimizer installed, or 
if youre going to install it 
=========================================================================== 
zend_extension=/usr/lib/php4/eaccelerator.so 
eaccelerator.shm_size=16 
eaccelerator.cache_dir=/tmp/eaccelerator 
eaccelerator.enable=1 
eaccelerator.optimizer=1 
eaccelerator.check_mtime=1 
eaccelerator.debug=0 
eaccelerator.filter= 
eaccelerator.shm_max=0 
eaccelerator.shm_ttl=0 
eaccelerator.shm_prune_period=0 
eaccelerator.shm_only=0 
eaccelerator.compress=1 
eaccelerator.compress_level=9 
cd ~ 
mkdir /tmp/eaccelerator/ 
chmod 0777 /tmp/eaccelerator/ 
5.After installed restart apache to check eaccelerator is installed. 
service httpd restart 

Verify: 
========= 
Run following command, and it should show Eaccelerator in the output as.
