CentOS6.5安装MySQL5.1.73数据库

一、描述

本博客主要介绍CentOS6.5安装MySQL数据库 、启动和关闭MySQL服务、MySQL的登录和退出，以及My SQL数据库root用户的密码配置和修改。

二、主要步骤

1、查看本系统是否已经安装有MySQL数据库

先查看本操作系统是否已经安装有操作系统，显示只有一个mysql的类库，并没有安装该数据库。

[tong@tong tongSoftware]$ rpm -qa | grep mysql
mysql-libs-5.1.73-3.el6_5.x86_64

2、使用yum安装MySQL数据库，需要安装mysql客户端和mysql-server端

[tong@tong tongSoftware]$ sudo yum install mysql mysql-server
3、查看已安装数据库 ，显示安装完毕的数据库

[tong@tong tongSoftware]$ rpm -qa | grep mysql
mysql-server-5.1.73-3.el6_5.x86_64
mysql-5.1.73-3.el6_5.x86_64
mysql-libs-5.1.73-3.el6_5.x86_64

4、查看数据库的启动状态，如果未启动则启动MySQL数据库

[tong@tong tongSoftware]$ sudo service mysqld status
[sudo] password for tong: 
mysqld is stopped
[tong@tong tongSoftware]$ sudo service mysqld start
Please report any problems with the /usr/bin/mysqlbug script!
[  OK  ]
Starting mysqld:  [  OK  ]

5、默认无密码以root用户登录数据库

[tong@tong tongSoftware]$ mysql -u root

6、输入exit退出数据库

mysql> exit

7、配置初始root密码

[tong@tong tongSoftware]$ sudo mysqladmin -u root password Admin123

格式;mysqladmin -u 用户 password  密码

8、root用户使用密码登录数据库

[tong@tong tongSoftware]$ sudo mysql -u root -p
Enter password:
