本脚本只适合从热点CentOS 5.x RDPM 1.0上升级使用,因为升级有一定的风险,所以请用户备份好数据,脚本本身也有备份功能,首先确认你没有在安装热点CentOS 5.x RDPM以后修改过MYSQL数据库相关的路径

本次升级是mysql 5.1.38升级到mysql 5.1.42

升级过程中需要关闭mysql数据库,所以依赖mysql数据库的站点会出现不能正常访问的现象

在终端下执行以下代码:

wget http://vbets.googlecode.com/files/mysql_up.sh

chmod +x mysql_up.sh

./mysql_up.sh

安装完成后,需要3-5分钟mysql才能正常使用!

以下是完整代码,方便大家以后升级其他版本的mysql
