安装MySQL

昨日，在CentOS5.7下安装MySQL5.0.92，安装成功。

       系统环境：

旧mysql版本：mysql-5.0.77-4.el5_6.6

新mysql版本：

MySQL-server-community-5.0.92-1.rhel5.i386.rpm 

MySQL-client-community-5.0.92-1.rhel5.i386.rpm

        现把安装过程分享给诸位！

     一、停掉mysqld服务

         # service mysqld stop

       二、卸载

1. 找出所有的MySQL版本包,然后一个个卸掉.

[root@localhost /]# rpm -qa | grep -i mysql

(1) 无依赖包的

[root@localhost/]# rpm -ev 包名

(2) 有依赖包的

yum -y remove 包名

2.找出含有mysql的所有文件夹和文件

[root@localhost /]# find / -name mysql

然后把找到的目录删除.

[root@localhost /]# rm -r 文件名

三、安装

1.安装Server

[root@localhost tmp]# rpm -ivh MySQL-server-community-5.0.92-1.rhel5.i386.rpm

2.安装Client

[root@localhost tmp]# rpm -ivh MySQL-client-community-5.0.92-1.rhel5.i386.rpm

完毕。

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h localhost.localdomain password 'new-password'

Alternatively you can run:
/usr/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

Please report any problems with the /usr/bin/mysqlbug script!
