CentOS下RPM方式安装MySQL5.6 上
引用http://www.centoscn.com/mysql/2015/0624/5729.html

此次安装在桌面环境下，使用shell命令进行安装，下载安装包为：
MySQL-5.6.25-1.linux_glibc2.5.i386.rpm-bundle.tar；
a. 检查MySQL及相关RPM包，是否安装，如果有安装，则移除（rpm –e 名称）
1 [root@localhost ~]# rpm -qa | grep -i mysql

2 mysql-libs-5.1.66-2.el6_3.x86_64

3 [root@localhost ~]# yum -y remove mysql-libs*

b. 选择Linux对应的RPM包，如下：
1 [root@localhost rpm]# ll

2 total 74364

3 -rw-r--r--. 1 root root 18442536 Dec 11 20:19 MySQL-client-5.6.15-1.el6.x86_64.rpm

4 -rw-r--r--. 1 root root 3340660 Dec 11 20:06 MySQL-devel-5.6.15-1.el6.x86_64.rpm

5 -rw-r--r--. 1 root root 54360600 Dec 11 20:03 MySQL-server-5.6.15-1.el6.x86_64.rpm

c. 安装MySQL
1 [root@localhost rpm]# rpm -ivh MySQL-server-5.6.15-1.el6.x86_64.rpm
--force --nodeps
2 [root@localhost rpm]# rpm -ivh MySQL-devel-5.6.15-1.el6.x86_64.rpm

3 [root@localhost rpm]# rpm -ivh MySQL-client-5.6.15-1.el6.x86_64.rpm

4 #修改配置文件位置

5 [root@localhost rpm]# cp /usr/share/mysql/my-default.cnf /etc/my.cnf

d. 初始化MySQL及设置密码
1 [root@localhost rpm]# /usr/bin/mysql_install_db
或者 /usr/bin/mysql_install_db --user=mysql
2 [root@localhost rpm]# service mysql start

3 [root@localhost rpm]# cat /root/.mysql_secret #查看root账号密码

4 # The random password set for the root user at Wed Dec 11 23:32:50 2013 (local time): qKTaFZnl

5 [root@localhost ~]# mysql -uroot –pqKTaFZnl

6 mysql> SET PASSWORD = PASSWORD('123456'); #设置密码为123456

7 mysql> exit

8 [root@localhost ~]# mysql -uroot -p123456

如果mysql登入密码忘了，就vim /etc/my.cnf [mysqld]下面加一句skip-grant-tables 保存退出，
重启mysql,可以等免密登入后修改密码 mysql -uroot -p
e. 远程登陆用户设置
01 mysql> use mysql;

02 mysql> select host,user,password from user;

03 +-----------------------+------+-------------------------------------------+

04 | host | user | password |

05 +-----------------------+------+-------------------------------------------+

06 | localhost | root | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 |

07 | localhost.localdomain | root | *1237E2CE819C427B0D8174456DD83C47480D37E8 |

08 | 127.0.0.1 | root | *1237E2CE819C427B0D8174456DD83C47480D37E8 |

09 | ::1 | root | *1237E2CE819C427B0D8174456DD83C47480D37E8 |

10 +-----------------------+------+-------------------------------------------+

11

12 mysql> update user set password=password('123456') where user='root';

13 mysql> update user set host='%' where user='root' and host='localhost';

14 mysql> flush privileges;

15 mysql> exit

f. 设置开机自启动
1 [root@localhost ~]# chkconfig mysql on

2 [root@localhost ~]# chkconfig --list | grep mysql

3 mysql 0:off 1:off 2:on 3:on 4:on 5:on 6:off

g. MySQL的默认安装位置

1 /var/lib/mysql/ #数据库目录

2 /usr/share/mysql #配置文件目录

3 /usr/bin #相关命令目录

4 /etc/init.d/mysql #启动脚本
