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 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

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

[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

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

[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
