用php -v查看得到以下错误信息：
PHP Fatal error: [Zend Optimizer] Zend Optimizer 3.3.0 is incompatible with eAccelerator 0.9.5.2 in Unknown on line
在CentOS5.2下的解决方法
（继续）
为：
mv /etc/php.d/eaccelerator.ini /etc/php.d/eaccelerator.ini save
然后，再把以下内容添加到/etc/php.ini中的[Zend]上方：
[eAccelerator]
; Enable eAccelerator extension module
zend_extension = /usr/lib/php/modules/eaccelerator.so
; Options for the eAccelerator module
eaccelerator.cache_dir = /var/cache/php-eaccelerator
eaccelerator.shm_size = 0
eaccelerator.enable = 1
eaccelerator.optimizer = 1
eaccelerator.check_mtime = 1
eaccelerator.filter = “”
eaccelerator.shm_max = 0
eaccelerator.shm_ttl = 3600
eaccelerator.shm_prune_period = 0
eaccelerator.shm_only = 0
eaccelerator.compress = 1
eaccelerator.compress_level = 9
eaccelerator.keys = “shm_and_disk”
eaccelerator.sessions = “shm_and_disk”
eaccelerator.content = “shm_and_disk”
eaccelerator.debug = 0
现在重启apache，
service httpd restart
用php -v 查看会看到如下内容：
[root@phpfree etc]# php -v

这表明Zend和eAccelerator已经正常运行了。
