至安装光盘server目录取出并补充安装：
php-common-5.1.6-15.el5.x86_64.rpm
php-pdo-5.1.6-15.el5.x86_64.rpm
从LinuxIDC.com的FTP下载补充安装： MySQL-shared-community-5.0.90-0.sles9.x86_64.rpm （内含重要的libmysqlclient.so.15）
php-mysql-5.1.6-15.el5.x86_64.rpm
注意： MySQL-shared-community-5.0.90-0.sles9.x86_64.rpm 一定要先于php-mysql-5.1.6-15.el5.x86_64.rpm安装。php-mysql-5.1.6-15.el5.x86_64.rpm的安装依赖于libmysqlclient.so.15。 MySQL-shared-community-5.1.45-1.rhel5.x86_64.rpm或其他版本内含的是libmysqlclient.so.16。安装时报出的相应依赖错误花些时间能找到相应的安装包解决问题。
最后重启下apache：
service httpd restart
以上安装也可解决如下apache启动问题：
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/mysql.so' - libmysqlclient.so.15: cannot open shared object file: No such file or directory in Unknown on line 0
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/mysqli.so' - libmysqlclient.so.15: cannot open shared object file: No such file or directory in Unknown on line 0
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/pdo_mysql.so' - libmysqlclient.so.15: cannot open shared object file: No such file or directory in Unknown on line 0
