RedHat Enterprise 6.5环境下使用eAccelerator优化网站性能

第一步:在做优化之前,首先对网站服务器的硬件做一下检测

1,内存信息:2G内存,swap容量为4G

[root@linuxcast ~]# 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信息,也可以通过cat /proc/cpuinfo查看

[root@linuxcast ~]# lscpu

Architecture:          x86_64

CPU op-mode(s):        32-bit, 64-bit

Byte Order:            Little Endian

CPU(s):                1

On-line CPU(s) list:   0

Thread(s) per core:    1

Core(s) per socket:    1

Socket(s):             1

NUMA node(s):          1

Vendor ID:             GenuineIntel

CPU family:            6

Model:                 58

Stepping:              9

CPU MHz:               3569.819

BogoMIPS:              7139.63

Hypervisor vendor:     VMware

Virtualization type:   full

L1d cache:             32K

L1i cache:             32K

L2 cache:              256K

L3 cache:              8192K

NUMA node0 CPU(s):     0

[root@linuxcast ~]# 


3,查看磁盘的续写性能:读取速度为:2544MB,吸入速度为847MB

[root@linuxcast ~]# hdparm -t /dev/sda


/dev/sda:

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

[root@linuxcast ~]#


4,对网站首页进行压力测试:ab命令

对指定网页进行10次并发,1000次请求进行压力测试:返回的结果是10.13

也就是说一天24小时可以承受的请求数量为:10*60*60*24=86400

 100%   1625 (longest request)

[root@linuxcast ~]# 


第二步:安装eAccelerator,提升网站性能

1,安装Development Tool工具

yum groupinstall -y "Development Tools"

2,安装php-devel

注:可以在pkgs.org上下载相关的版本(必须和php版本相同)

[root@linuxcast ~]# 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

[root@linuxcast ~]# cd 

[root@linuxcast ~]# 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

[root@linuxcast ~]# rpm -ivh php-devel-5.3.3-26.el6.x86_64.rpm 

3,下载并安装eAccelerator

[root@linuxcast ~]# cd /usr/local/


下载eAccelerator并命名为master.zip:

[root@linuxcast local]# wget https://github.com/eaccelerator/eaccelerator/zipball/master -O master.zip

[root@linuxcast local]# unzip master.zip 


重命名解压缩出来的文件夹为eAccelerator:

[root@linuxcast local]# mv eaccelerator-eaccelerator-42067ac/ eaccelerator

[root@linuxcast local]# cd eaccelerator/

[root@linuxcast 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

config.m4      dasm.php     eaccelerator.c  ea_dasm.c               ea_restore.c  fnmatch.c     mm.c           opcodes.h  README.win32

[root@linuxcast eaccelerator]# ls configure

ls: cannot access configure: No such file or directory


在eAccelerator目录中执行phpize命令,生成configure文件:

[root@linuxcast eaccelerator]# phpize 

Configuring for:

PHP Api Version:         20090626

Zend Module Api No:      20090626

Zend Extension Api No:   220090626

[root@linuxcast eaccelerator]# ls configure

configure


安装eAccelerator:

[root@linuxcast eaccelerator]# ./configure

[root@linuxcast eaccelerator]# make && make install


第三步:编辑eAccelerator的配置文件:

在/etc/php.d目录下创建eacceleractor.ini

内容参照:https://github.com/eaccelerator/eaccelerator网页上的

To install as PHP extension:

eAccelerator.ini文件内容:

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"


创建eAccelerator虚拟目录:

mkdir /tmp/eaccelerator


设置eAccelerator目录的权限:
chmod 0777 /tmp/eaccelerator


注:配置完成之后需要重新启动httpd服务

service httpd restart


第四步:安装好eAccelerator之后,再次对网站首页进行压力测试:

测试结果:

[root@linuxcast php.d]# ab -c 10 -n 1000 http://www.linuxcast.net/index.php

[root@linuxcast php.d]# 


可以看到优化后的返回结果为:Requests per second:    23.96 [#/sec] (mean)

也就是说,是优化之前的三倍。


php的加速器除了eAccelerator之外还有xcache、APC(Alternative PHP Cache)等...
