CentOS下使用rpm包安装MySQL
CentOS下安装MySQL步骤：
第一、 http://www.mysql.com/downloads/mysql-4.0.html下载MySQL-client-5.0.96-1.glibc23.x86_64.rpm和
MySQL-server-5.0.96-1.glibc23.x86_64.rpm
第二、安装服务端：
[root@linuxidc mysql]# rpm -ivh MySQL-server-5.1.73-1.glibc23.i386.rpm
显示信息：
Preparing... ########################################### [100%]
1:MySQL-server ########################################### [100%]
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
。。。。。
Please report any problems with the /usr/bin/mysqlbug script!
如出现如上信息，则表示服务器端安装成功。
安装客户端：[root@linuxidc mysql]# rpm -ivh MySQL-client-5.1.73-1.glibc23.i386.rpm
显示如下信息则表明安装成功：
Preparing... ########################################### [100%]
1:MySQL-client ########################################### [100%]
若安装过程中报该错误！！！
file /usr/share/mysql/czech/errmsg.sys from install of MySQL-server-5.1.73-1.glibc.i386 conflicts with file from package mysql-libs-5.1.73-1.glibc.i386
原因：已存在mysql-libs-5.1.73-1.glibc.i386的库（这是linux自带的）所以需要先删除以前的库才能安装
rpm -e mysql-libs-5.1.73-1.glibc.i386 --nodeps 强制卸载！
第三、启动mysql服务
[root@linuxidc sean]# /etc/init.d/mysql start 或者
[root@linuxidc sean]# mysqld_safe &
通过netstat命令查看mysql是否启动成功
[sean@linuxidc ~]$ netstat -nat
Active Internet connections (servers and established)

tcp 0 0 ::1:631 :::* LISTEN
tcp 0 0 ::1:6010 :::* LISTEN
mysql默认端口号为3306，以上信息中出现3306端口号，则启动成功
查看mysql进程：
[root@linuxidc sean]# ps -e
第四、停止mysql服务：
[root@linuxidc sean]# /usr/bin/mysqladmin -u root -p shutdown
重启mysql服务：/etc/init.d/mysql restart
第五、重启linux之后，启动mysql服务
[root@linuxidc sean]# /usr/init.d/mysql start
[root@linuxidc mysql]# mysql

退出mysql：

设置mysql密码
[root@linuxidc mysql]# /usr/bin/mysqladmin -u root password '*****'
登录mysql
[root@linuxidc mysql]# mysql -u root -p
Enter password:

出现以上信息表明登录成功！！！
第六、卸载mysql
用rpm包卸载：
[root@linuxidc sean]# rpm -qa|grep MySQL
MySQL-client-5.1.73-1.glibc23.i386
MySQL-server-5.1.73-1.glibc23.i386
执行此命令卸载 [root@linuxidc sean]# rpm -e --nodeps MySQL-client-5.1.73-1.glibc23.i386
[root@linuxidc sean]# find / -name mysql
/var/lib/mysql
/var/lib/mysql/mysql
/var/lock/subsys/mysql
/usr/lib/mysql
/usr/share/mysql
/usr/mysql
/usr/bin/mysql
/etc/logrotate.d/mysql
/etc/rc.d/init.d/mysql
可以手动删除mysql相关的文件
[root@linuxidc sean]# rm -rf /var/lib/mysql
后面的操作mysql和windows下一样了。。。
