How to install eAccelerator on VPS in LINUX

EAccelerator acceleration is only one type of acceleration. eAccelerator is an open-source php accelerator that optimizes and dynamically caches content, improving the cache performance of php scripts, linux is also a commonly used software. In windows, We have fastcgi with iis for processing. This article does not introduce windows, which mainly introduces how to configure and install eAccelerator in linux.

1. installation and configuration on VPS

Perform the following operations in ssh. Check whether the make module has been installed. If not, install the make module first:

The Code is as follows:	Copy code
Yum install make

Run the following command line by line. Download-unzip-switch directory-configure compilation and installation-switch to root directory-delete-create cache directory-Modify cache directory permissions.

The Code is as follows:	Copy code
Wget http://www.hwzj.org/soft/Linux/eaccelerator-0.9.6.1.zip Tar xjf eaccelerator-0.9.6.1.zip Cd eaccelerator-0.9.6.1 /Usr/bin/phpize ./Configure-enable-eaccelerator = shared-with-php-config =/usr/bin/php-config Make Make install Mkdir/tmp/eaccelerator Chmod 777/tmp/eaccelerator

Create the configuration file eaccelerator. ini in/etc/php. d:

The Code is as follows:	Copy code
Vim/etc/php. d/eaccelerator. ini

Edit the file with the following content: OPENVZ and XEN are different:

The Code is as follows:

Copy code

OPENVZ: Extension = "eaccelerator. so" Eaccelerator. shm_size = "0 ″ Eaccelerator. cache_dir = "/tmp/eaccelerator" Eaccelerator. enable = "1 ″ Eaccelerator. optimizer = "1 ″ Eaccelerator. check_mtime = "1 ″ Eaccelerator. debug = "0 ″ Eaccelerator. log_file = "/var/log/eaccelerator_log" 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. keys = "disk_only" Eaccelerator. sessions = "disk_only" Eaccelerator. content = "disk_only" Extension = "eaccelerator. so" Eaccelerator. shm_size = "64 ″ Eaccelerator. cache_dir = "/tmp/eaccelerator" Eaccelerator. enable = "1 ″ Eaccelerator. optimizer = "1 ″ Eaccelerator. check_mtime = "1 ″ Eaccelerator. debug = "0 ″ Eaccelerator. log_file = "/var/log/eaccelerator_log" 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. keys = "shm_and_disk" Eaccelerator. sessions = "shm_and_disk" Eaccelerator. content = "shm_and_disk" Restart apache or lighttpd Service httpd restart Service lighttpd restart

3. verify whether the installation is successful

Open several php pages, switch to the cache directory/tmp/eaccelerator in ssh, and use dir to check whether there are cached files (folders ), 0 1 2 3 4 5 6 7 8 9 a B c d e f

The Code is as follows:	Copy code
Cd/tmp/eaccelerator Dir

View phpinfo (). If so, the installation and configuration are successful.

Ii. Considerations for installing eaccelerator in vps

The above is a successful installation process, and many problems have been encountered in the middle. My vps is centos linux. After vps is activated successfully, it comes with Php5.1.6 and Mysql5.0.45. To install Yike CRM, you need to install Zend Optimizer3.3.0, it is best to install the eaccelerator cache accelerator to improve the system running efficiency.

PHP5.1.6 is installed by default, and the make command is forbidden on vps. Therefore, software installation on vps can only be installed through rpm or the compiled installation package.

Zend Optimizere is easy to install. Download the tar package, use the tar xzvf command to decompress the tar package, and then execute install. sh file. You can install Zend Optimizer according to the wizard. Pay attention to php. the ini path must be correct. When executing the current directory command, add ". /", indicating the current directory.

The rpm package is not found on the official website of eaccelerator, and google will soon find it here. If the installation package is incorrect, you can use the source code package of rpmbuild rpm. After the installation is successful, the so file is generated in the php/modules directory, and in the/etc/php. d/directory to generate eaccelerator. INI file. php will automatically call php when it is started. d directory. Restart apache and check whether the startup fails. Check/var/log/httpd/error_log and find that the PHP Fatal error is returned when apache is started: [Zend Optimizer] Zend Optimizer 3.3.0 is incompatible with eAccelerator 0.9.5 in Unknown on line 0. google this error message, view several URLs, and finally find a solution, in the past, we had to put the eaccelerator configuration parameters before the Zend Optimizer parameter and delete/etc/php. d/eaccelerator. iniw file, restart apache, start properly, view phpinfo, and finally see the familiar

At the same time, it also understands why the ea configuration parameters should be placed before the zend configuration item.
