环境：centos6.5
两台主机：
一台master,
一台node
环境部署：关闭iptable 关闭selinux
关闭seliunx
[root@xie2 ~]# setenforce 0
[root@xie2 ~]# cat /etc/sysconfig/selinux
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disable
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
一、检查系统是否安装其他版本的MYSQL数据
yum list installed | grep mysql
yum -y remove mysql-libs.x86_64
二、安装及配置
wget http://repo.mysql.com/mysql-community-release-el6-5.noarch.rpm
rpm -ivh mysql-community-release-el6-5.noarch.rpm
yum repolist all | grep mysql
1、安装MYSQL数据库
yum install mysql-community-server -y
设置用户，用户组
vim /etc/my.cnf
datadir=/usr/local/mysql
socket=/var/lib/mysql/mysql.sock
[root@xie1 ~]# chown -R mysql /usr/local/mysql/
[root@xie1 ~]# chgrp -R mysql /usr/local/mysql/
2、设置为开机启动
chkconfig --list | grep mysqld
chkconfig mysqld on
初始化启动：
/etc/init.d/mysqld start
3、设置密码
/usr/bin/mysqladmin -u root password '123456'
4、修改root密码
mysql -uroot -p123456
mysql> select Host,User,Password from user where User='root';

1、使用空的初始密码登录mysql账号：
mysql-uroot -p
2、修改root密码：
mysql> update user set Password=password("123456") where User='root';
Query OK, 4 rows affected (0.01 sec)
Rows matched: 4 Changed: 4 Warnings: 0
mysql> flush privileges;
Query OK, 0 rows affected (0.04 sec)
mysql> select Host,User,password from user where user='root';
