3、如果你只是需要安装mysql,那么只需要安装如下文件
MySQL-server-5.6.22-1.linux_glibc2.5.x86_64.rpm
MySQL-client-5.6.22-1.linux_glibc2.5.x86_64.rpm
MySQL-devel-5.6.22-1.linux_glibc2.5.x86_64.rpm

MySQL-server-5.5.25a-1.rhel5.x86_64.rpmMySQL-client-5.5.25a-1.rhel5.x86_64.rpmMySQL-devel-5.5.25a-1.rhel5.x86_64.rpm三个文件换成MySQL-server-5.6.22-1.linux_glibc2.5.x86_64.rpm、MySQL-client-5.6.22-1.linux_glibc2.5.x86_64.rpm和MySQL-devel-5.6.22-1.linux_glibc2.5.x86_64.rpm三个rpm文件即可)

查看当前安装的linux版本

命令:lsb_release -a 如下图所示

通过上图中的数据可以看出安装的版本为CentOS release 6.3,所以我们需要下载CentOS release 6.3对应的mysql安装包

下载mysql安装文件

1、如果你只是需要安装mysql,那么只需要安装如下文件
      MySQL-server-5.5.25-1.rhel5
      MySQL-devel-5.5.25-1.rhel5
      MySQL-client-5.5.25-1.rhel5
2、如果你需要搭建Linux整个实施环境(nginx、php、mysql、tomcat、jdk、服务器多域名配置)
请参考我的Linux项目实施系列教程:
CenterOS 6.3 64位搭建nginx1.3+php5.4.3+mysql5.5.25+tomcat7+jdk7安装

安装mysql5.5.25

1、进入安装文件的目录
2、安装mysql服务端
# rpm -ivh MySQL-server-5.5.25a-1.rhel5.x86_64.rpm
如图:mysql-server安装
CentOS 6.3 64位下mysql5.5.25安装图解教程
安装过程中可能出现后面的错误:error: Failed dependencies: libaio.so.1()(64bit) is needed by MySQL-server

(蓝色部分可以跳过)

(1) 安装完成后,安装进程会在Linux中添加一个mysql组,以及属于mysql组的用户mysql。可通过id命令查看:

[root@localhost JavaEE]#id mysql

uid=496(mysql)gid=493(mysql) groups=493(mysql)

(2)MySQL服务器安装之后虽然配置了相关文件,但并没有自动启动mysqld服务,需自行启动:[root@localhost JavaEE]#service mysql start

Starting MySQL.. SUCCESS!

(3) 可通过检查端口是否开启来查看MySQL是否正常启动:

[root@localhost JavaEE]#netstat -anp|grep 3306

tcp        0     0 0.0.0.0:3306               0.0.0.0:*                   LISTEN      34693/mysqld 


3、安装mysql客户端、mysql-devel
# rpm -ivh MySQL-client-5.5.25a-1.rhel5.x86_64.rpm
# rpm -ivh MySQL-devel-5.5.25a-1.rhel5.x86_64.rpm
如图:mysql-client-devel
CentOS 6.3 64位下mysql5.5.25安装图解教程
启动mysql服务
# service mysql start

3.初始密码问题

  安装好mysql之后,一般有两种情况:

第一种情况:为root用户设置了一个随机密码(在CentOS上经常遇到这种情况)

随机密码存放位置:/root/.mysql_secret(这个是隐藏文件,想看密码直接输入:vi /root/.mysql_secret)

文件中的内容如下:

 # The random password set for the root user at Fri Feb  6 11:18:43 2015 (local time): eSADSovuu3jDdxs9

         #

  第一步:取到随机密码登录;

  第二步:登录成功后修改密码命令如下:

sql>set passwrod = password("newpassword");

第二种情况:一开始root未设置密码

 修改mysql中root的初始化密码

1、命令如下:
# /usr/bin/mysqladmin -u root password ‘rootadmin’
格式:mysqladmin -u用户名 -p旧密码 password 新密码
2、例子
# /usr/bin/mysqladmin -u root password ‘rootadmin’
注:因为开始时root没有密码,所以-p旧密码一项就可以省略了

3、用新的密码进行登录,如下图所示:

重启与停止mysql服务

启动方式1:service mysql start
启动方式2:/etc/init.d/mysql start
停止方式1:service mysql stop
停止方式2:/etc/init.d/mysql shutdown
重启方式1:service mysql restart
重启方式2:/etc/init.d/mysql restart
