1. 下载
http://downloads.zend.com/optimizer/3.3.9/ZendOptimizer-3.3.9-linux-glibc23-x86_64.tar.gz
2. 安装
cd 下载目录
tar zxvf ZendOptimizer-3.3.9-linux-glibc23-x86_64.tar.gz
cd ZendOptimizer-3.3.9-linux-glibc23-x86_64
注意版本对应，我的php版本是5.2.6
cp data/5_2_x_comp/ZendOptimizer.so /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/
修改php.ini
vi /usr/local/php-5.2.14/etc/php.ini
按住shift+g到最后并添加:
[Zend]
zend_extension=”/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/ZendOptimizer.so”
就可以了
3. 测试是否安装成功
php -v
[root@localhost d]# /usr/local/php-5.2.14/bin/php -v
