Php is compiled against the wrong mysql lib.
PHP 是针对错误的 mysql 库编译的。
I suggest you to check if the php executable is the one provided with the rpm package.
我建议您检查 php 可执行文件是否是随 rpm 包提供的可执行文件。
You can also try a dirty workaround, go to the directory where the libmysqlclient.so.16 is located and write:
您也可以尝试一个肮脏的解决方法，转到 libmysqlclient.so.16 所在的目录并写入：
ln -s libmysqlclient.so.16 libmysqlclient.so.18
ln -s libmysqlclient.so.16 libmysqlclient.so.18

A better option is remove your php and install the version 5.3.23:
更好的选择是删除您的 php 并安装 5.3.23 版本：
- yum remove php
- wget http://repo.webtatic.com/yum/centos/5/latest.rpm
- rpm -ivh latest.rpm
- enable the webtatic repository and disable the rhea repository (/etc/yum.repos.d/)
- yum install php
- yum 删除 php
- wget http://repo.webtatic.com/yum/centos/5/latest.rpm
- rpm -ivh 最新.rpm
- 启用 webtatic 存储库并禁用 rha 存储库 (/etc/yum.repos.d/)
- yum 安装 php
