Install eAccelerator
 
Sudo apt-get install php5-dev
 
Download eAccelerator
 
Wget http://bart.eaccelerator.net/source/0.9.6.1/eaccelerator-0.9.6.1.tar.bz2
 
Tar jxvf eaccelerator-0.9.6.1.tar.bz2
 
Cd eaccelerator-0.9.6.1
 
Phpizesudo./configure-enable-eaccelerator = sharedsudo make
 
Qii @ ubuntu :~ /Tmp/eaccelerator-0.9.6.1 $ sudo make installInstalling shared extensions:/usr/lib/php5/20060613 + lfs/
 
Modify the php. ini file and install it as the Zend extension. It is best to put it at the beginning and put it before [zend] To avoid inexplicable problems:
 
Sudo vi/etc/php5/apache2/php. ini
 
[Eaccelerator] zend_extension = "/usr/lib/php5/20060613 + lfs/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" eaccelerator. allowed_admin_path = "/var/www/control. php"
 
Create cache directory
 
Eaccelerator. cache_dir = "/var/cache/eaccelerator" the cache path is defined here.
 
The default value is/tmp/eaccelerator. This is very simple because anyone can write to this directory, but it is unwise because the directory is automatically cleared after restart. A better solution is/var/cache/eaccelerator. Create the Directory and make sure it is writable to the user of the eAccelerator (generally, this user is your web server operator, and may be www-data ). Use the default value to continue:
 
Mkdir/tmp/eaccelerator
 
Chmod 777/tmp/eaccelerator
 
Change to/var/cache/eaccelerator.
 
Eaccelerator. cache_dir = "/var/cache/eaccelerator"
 
Sudo mkdir/var/cache/eacceleratorsudo chown root: www-data/var/cache/eacceleratorsudo chmod u = rwx, g = rwx, o =/var/cache/eaccelerator
 
Copy control file control. php to the website root directory
 
Sudo cp control. php/var/www/htdocs/
 
Modify $ user and $ pw of control. php. The default values are admin and eAccelerator.
 
Sudo vi/var/www/htdocs/control. php
 
Restart apache
 
Sudo/etc/init. d/apache2 restart
 
Open http: // localhost/control. ph
