1.查看是否安装了MySQL
[root@localhost ~]# rpm -qa | grep 'mysql' [root@localhost ~]#
显示没有安装。
2.安装mysql客户端
[root@localhost ~]# yum -y install mysql [root@localhost ~]#
3.安装mysql服务端
[root@localhost ~]# yum -y install mysql-server mysql-devel [root@localhost ~]#
4.安装mysql客户端和服务端
[root@localhost ~]# yum -y install mysql mysql-server mysql-devel [root@localhost ~]#
5.查询mysql是否已安装完成
以安装mysql客户端和服务端为例：
[root@localhost ~]# rpm -qa | grep 'mysql' mysql-libs-5.1.73-8.el6_8.x86_64 mysql-devel-5.1.73-8.el6_8.x86_64 mysql-5.1.73-8.el6_8.x86_64 mysql-server-5.1.73-8.el6_8.x86_64 [root@localhost ~]#
6.启动mysql
[root@localhost ~]# service mysqld start Starting mysqld: [ OK ] [root@localhost ~]#
或使用下面命令：
[root@localhost ~]# /etc/init.d/mysqld start Starting mysqld: [ OK ] [root@localhost ~]#
7.查看mysql状态
[root@localhost ~]# service mysqld status mysqld (pid 3043) is running... [root@localhost ~]#
8.进入mysql
进入mysql---注：mysql安装后的root默认没有密码。
以root用户名进入mysql：
[root@localhost ~]# mysql -uroot -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 3 Server version: 5.1.73 Source distribution Copyright (c) 2000, 2013, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql>
9.将mysql设置开机启动项
[root@localhost ~]#chkconfig mysqld on [root@localhost ~]#
好了，此时安装mysql完成了。
