directadmin安装Zend Optimizer

在directadmin中安装Zend Optimizer组件，首先要讲PHP5.3降级为PHP5.2

cd /usr/local/directadmin/custombuild

./build clean

./build set php5_ver 5.2

./build set php5_cli no

./build set php5_cgi yes

./build php n

然后安装zend：

cd /usr/local/directadmin/custombuild

./build set zend yes

./build zend

安装完成重启apache即可

service httpd restart
