1、下载rpm安装文件

client:
[root@localhost mysql]wget http://dev.mysql.com/get/MySQL-client-5.6.13-1.el6.x86_64.rpm
server:
[root@localhost mysql]wget http://dev.mysql.com/get/MySQL-server-5.6.13-1.el6.x86_64.rpm
devel:
[root@localhost mysql]wget http://dev.mysql.com/get/MySQL-devel-5.6.13-1.el6.x86_64.rpm

2、安装server、devel、client：

[root@localhost mysql]# rpm -ivh –replacefiles MySQL-server-5.6.13-1.el6.x86_64.rpm
Preparing… ########################################### [100%]
1:MySQL-server ########################################### [100%]
[root@localhost mysql]# rpm -ivh –replacefiles MySQL-client-5.6.13-1.el6.x86_64.rpm
Preparing… ########################################### [100%]
1:MySQL-client ########################################### [100%]
[root@localhost mysql]# rpm -ivh –replacefiles MySQL-devel-5.6.13-1.el6.x86_64.rpm
Preparing… ########################################### [100%]
1:MySQL-devel ########################################### [100%]

要移除安装可以使用 rpm -e MySQL-server 、 rpm -e MySQL-devel、MySQL-client即可；

3、初始化数据库：

命令：/usr/bin/mysql_install_db

4、启动mysql服务：

命令：service mysql start

使用命令ps -ef | grep mysql 查看mysql进程：

[root@localhost mysql]# ps -ef | grep mysql

root 3992 1 0 01:15 pts/0 00:00:00 /bin/sh /usr/bin/mysqld_safe –datadir=/var/lib/mysql –pid-file=/var/lib/mysql/localhost.pid
mysql 4170 3992 2 01:15 pts/0 00:00:00 /usr/sbin/mysqld –basedir=/usr –datadir=/var/lib/mysql –plugin-dir=/usr/lib64/mysql/plugin –user=mysql –log-error=/var/log/mysqld.log –pid-file=/var/lib/mysql/localhost.pid –socket=/var/lib/mysql/mysql.sock
root 4199 3338 0 01:15 pts/0 00:00:00 grep mysql

5、重置密码：
1）更改/etc/my.cnf文件
[root@localhost mysql]# vi /etc/my.cnf
在[mysqld]下添加skip-grant-tables，保存退出。

2）重启mysql
[root@localhost mysql]service mysql restart

3)登录：
[root@localhost mysql]mysql -u root -p
Enter password:
这里直接按回车登录。
