想在Centos5.2上装一个discuz论坛，在突破了apache权限问题后，发现discuz的提示信息里显示不支持mysql：
mysql_connect() 不支持 请检查mysql 模块是否正确加载
我自己写个测试文件
- <?php
- phpinfo();
- ?>
<?php phpinfo(); ?>
执行后显示：

–without-mysql
/usr/lib/php/modules/里面根本没有mysql.so
因此找到centos5.2安装盘，找到CentOS目录下的
php-mysql-5.1.6-20.el5.i386.rpm
上传，安装：
[zhouhh@cvttssw ~]$ sudo rpm -ivh php-mysql-5.1.6-20.el5.i386.rpm
warning: php-mysql-5.1.6-20.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID e8562897
error: Failed dependencies:
php-pdo is needed by php-mysql-5.1.6-20.el5.i386
再上传php-pdo-5.1.6-20.el5.i386.rpm
[zhouhh@cvttssw ~]$ sudo rpm -ivh php-pdo-5.1.6-20.el5.i386.rpm
[zhouhh@cvttssw ~]$ sudo rpm -ivh php-mysql-5.1.6-20.el5.i386.rpm
成功
再查看so文件：
[zhouhh@cvttssw ~]$ ls /usr/lib/php/modules/
dbase.so ldap.so mysqli.so mysql.so pdo_mysql.so pdo.so pdo_sqlite.so phpcups.so
mysql.so存在了。
配置/etc/php.ini
extension=mysql.so
extension=mysqli.so
extension=pdo_MySQL.so
保存，重启httpd
刷新网页，还是显示mysql_connect() 不支持
难道非要下载php源码重编译吗？
重启了一下mysql，刷新网页，mysql已经能连上了。
但phpinfo还是显示–without-mysql，不管他了。
