Web server Deployment and optimization---3---Improve Web server performance with Eaccelerator (rhel6.5)

RedHat Enterprise 6.5 environment using Eaccelerator to optimize website performance

The first step: Before the optimization, first of the Web server hardware to do a test

1, Memory information: 2G memory, swap capacity 4G

[Email protected] ~]# free-m

Total used free shared buffers Cached

mem:1870 1228 642 0 47 435

-/+ buffers/cache:744 1125

swap:4095 0 4095

2,CPU information can also be viewed through cat/proc/cpuinfo

[Email protected] ~]# LSCPU

3, check the disk's resume performance: Read speed: 2544MB, suction speed of 847MB

[Email protected] ~]# hdparm-t/DEV/SDA

/DEV/SDA:

Timing buffered disk reads:2544 MB in 3.00 seconds = 847.63 mb/sec

[Email protected] ~]#

4, stress test on the homepage of the website: AB command

10 concurrent, 1000 requests for stress tests on the specified Web page: The returned result is 10.13

That means 24 hours a day. The number of requests that can be sustained is: 10*60*60*24=86400

Step Two: Install Eaccelerator to improve website performance

1, Install development tool tools

Yum groupinstall-y "Development Tools"

2, install Php-devel

Note: You can download the relevant version on pkgs.org (must be the same as the PHP version)

[Email protected] ~]# Rpm-qa | grep php

Php-pdo-5.3.3-26.el6.x86_64

Php-gd-5.3.3-26.el6.x86_64

Php-5.3.3-26.el6.x86_64

Php-common-5.3.3-26.el6.x86_64

Php-devel-5.3.3-26.el6.x86_64

Php-mysql-5.3.3-26.el6.x86_64

Php-xml-5.3.3-26.el6.x86_64

Php-cli-5.3.3-26.el6.x86_64

Php-pear-1.9.4-4.el6.noarch

[[Email protected] ~]# CD

[Email protected] ~]# wget http://mirror.centos.org/centos/6/os/x86_64/Packages/php-devel-5.3.3-26.el6.x86_64.rpm

--2014-08-08 14:11:48--http://mirror.centos.org/centos/6/os/x86_64/Packages/php-devel-5.3.3-26.el6.x86_64.rpm

[Email protected] ~]# RPM-IVH php-devel-5.3.3-26.el6.x86_64.rpm

3. Download and install Eaccelerator

[Email protected] ~]# cd/usr/local/

Download the eaccelerator and name it master.zip:

[Email protected] local]# wget Https://github.com/eaccelerator/eaccelerator/zipball/master-O master.zip

[Email protected] local]# Unzip Master.zip

Rename the extracted folder to Eaccelerator:

[Email protected] local]# MV Eaccelerator-eaccelerator-42067ac/eaccelerator

[Email protected] local]# CD eaccelerator/

[[email protected] eaccelerator]# ls

AUTHORS config.w32 debug.c eaccelerator.h ea_dasm.h ea_restore.h fnmatch.h mm.h OPTIMIZE.C Win32

bugreport.php control.php debug.h eaccelerator.ini ea_info.c ea_store.c Makefile.frag NEWS php_highlight.php

ChangeLog COPYING Doc eaccelerator_version.h ea_info.h ea_store.h makefile.in opcodes.c Readme

CONFIG.M4 dasm.php eaccelerator.c ea_dasm.c ea_restore.c fnmatch.c mm.c opcodes.h Readme.win32

[[email protected] eaccelerator]# ls Configure

Ls:cannot access configure:no such file or directory

Execute the phpize command in the Eaccelerator directory to generate the Configure file:

[Email protected] eaccelerator]# phpize

Configuring for:

PHP Api version:20090626

Zend Module Api no:20090626

Zend Extension Api no:220090626

[[email protected] eaccelerator]# ls Configure

Configure

Install Eaccelerator:

[Email protected] eaccelerator]#./configure

[[email protected] eaccelerator]# make && make install

Step three: Edit the eaccelerator configuration file:

Create Eacceleractor.ini under the/ETC/PHP.D directory

Content reference: Https://github.com/eaccelerator/eaccelerator on the Web page

To install as PHP extension:

Eaccelerator.ini File Contents:

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_ttl= "0"
eaccelerator.shm_prune_period= "0"

eaccelerator.shm_only= "0"

To create a eaccelerator virtual directory:

Mkdir/tmp/eaccelerator

To set permissions for the Eaccelerator directory:
chmod 0777/tmp/eaccelerator

Note: The HTTPD service needs to be restarted after the configuration is complete

Service httpd Restart

Fourth step: After the installation of Eaccelerator, once again on the site first stress test:

Test results:

You can see that the optimized return result is:requests per second:23.96 [#/sec] (mean)

That is, three times times before the optimization.

PHP Accelerator In addition to Eaccelerator also have XCache, APC (alternative php Cache) and so on ...
