Linux RPM方式安装MySQL5.6.31

Linux + MySQL环境：

CentOS 6.5

MySQL-client-5.6.31.rpm  ----------  MySQL-client-5.6.31-1.el6.x86_64.rpm
MySQL-server-5.6.31.rpm  ----------  MySQL-server-5.6.31-1.el6.x86_64.rpm

1. 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*

Centos自带的mysql无法卸载，解决办法：

rpm -e --nodeps mysql-libs-5.1.66-2.el6_3.x86_64

2. 下载Linux对应的RPM包，如下：

MySQL-client-5.6.31.rpm

MySQL-server-5.6.31.rpm

（已下载好，winscp上传到CentOS）

3. 安装MySQL 

1	[root@localhost rpm]# rpm -ivh MySQL-server-5.6.31.rpm

2	[root@localhost rpm]# rpm -ivh MySQL-client-5.6.31.rpm

3

#修改配置文件位置

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

4. 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

5. 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

6. 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

7. 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

附：

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.

[client]
password        = 123456  
port            = 3306  
default-character-set=utf8  
[mysqld]  
port            = 3306  
character_set_server=utf8  
character_set_client=utf8  
collation-server=utf8_general_ci  
#(注意linux下mysql安装完后是默认：表名区分大小写，列名不区分大小写； 0：区分大小写，1：不区分大小写)  
lower_case_table_names=1  
#(设置最大连接数，默认为 151，MySQL服务器允许的最大连接数16384; )  
max_connections=1000  
[mysql]  
default-character-set = utf8 

查看字符集

show variables like '%collation%';

show variables like '%char%';
