baseurl=http://www.okserver.cn/media/EL$releasever/$basearch/
enabled=1
gpgcheck=1
gpgkey=http://www.okserver.cn/media/RPM-GPG-KEY-jlitka

 yum update php
 
安装ZendOptimizer
1、下载文件：
http://downloads.zend.com/optimizer/3.3.9/ZendOptimizer-3.3.9-linux-glibc23-i386.tar.gz  （32位）
http://downloads.zend.com/optimizer/3.3.9/ZendOptimizer-3.3.9-linux-glibc23-x86_64.tar.gz  （64位）
2、解压
解压后把ZendOptimizer-3.3.9-linux-glibc23-x86_64/data/5_2_x_comp目录下的ZendOptimizer.so拷贝到某一个目录，比如/usr/local/Zend/lib/
Zend optimizer 3.3.9有一些新的改动，不需要安装了，直接在php.ini文件里面引用.so文件即可：
3、修改/etc/php.ini文件
找到：zend.ze1_compatibility_mode = Off
修改为：zend.ze1_compatibility_mode = On
在末尾加上以下文字：
[Zend Optimizer]
zend_optimizer.optimization_level=1
zend_extension="/usr/local/Zend/lib/ZendOptimizer.so"
4、重启httpd服务，通过php -v 可以看效果。
 
安装eaccelerator
直接yum install php-eaccelerator
如果找不到，线 yum search eaccelerator
 
 
虚拟主机安装时注意，如果出现多个域名都指向同一个目录的情况
NameVirtualHost 127.0.0.1:80    #这句一定要和 <VirtualHost 127.0.0.1:80>配合才可以。
<VirtualHost 127.0.0.1:80>
DocumentRoot /var/www/html
ServerName t.okserver.cn
< Directory "/var/www/html">
allow from all
Options +Indexes
< /Directory>
< /VirtualHost>

< VirtualHost 127.0.0.1:80>
DocumentRoot /var/www/html/test/
ServerName test.okserver.cn
< Directory "/var/www/html/test/">
allow from all
Options +Indexes
< /Directory>
< /VirtualHost>
 
开启缓存Expires模块要有
ExpiresActive   on
ExpiresDefault   "access plus 86400 second"
