RPM方式安装MySQL5.6

RPM方式安装MySQL5.6 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. 下载Linux对

RPM方式安装MySQL5.6

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. 下载Linux对应的RPM包，如：CentOS6.4_64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

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

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

e. 允许远程登陆

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

修改字符集和数据存储路径

配置/etc/my.cnf文件,修改数据存放路径、mysql.sock路径以及默认编码utf-8.
