mysql 主从

 mysql 安装在这里就不说了，可以参考我的安装笔记

http://www.cnblogs.com/vick51/p/7048417.html 

下面直接开始配置mysql 主从

mysql 主从环境介绍

Mysql Master　　系统：Centos6.*　　mysql version mysql-5.7.17  IP：192.168.1.223
Mysql Slave　　  系统：Centos6.*　　mysql version mysql-5.7.17  IP：192.168.1.224

开始配置 mysql 主从：

1、在master上创建主从用户
[root@m3 ~]# mysql -uroot -pyou_password
mysql> grant replication slave on *.* to vick@'192.168.1.224' identified by 'vick_slave';
mysql> flush privileges;
mysql> show master status\G
*************************** 1. row ***************************
             File: mysql-bin.000002
         Position: 997
     Binlog_Do_DB: 
 Binlog_Ignore_DB: 
Executed_Gtid_Set: 89a442a1-511d-11e7-b608-000c29789b2f:1-4
1 row in set (0.00 sec)

2、在slave上配置从库
vim /etc/my.cnf 
server_id = 2  ## 注意数据库的唯一ID不能一样
[root@m4 ~]# mysql -uroot -pwangkai
mysql> change master to \
    -> master_host='192.168.1.223', \
    -> master_user='vick',\
    -> master_password='vick_slave', \
    -> master_port=3306, \
    -> master_log_file='mysql-bin.000002',\
    -> master_log_pos=997;

Query OK, 0 rows affected, 2 warnings (0.02 sec)
mysql> start slave;
Query OK, 0 rows affected (0.00 sec)
mysql> show slave status\G

当这两项为yes 说明显示正常
Slave_IO_Running: Yes
Slave_SQL_Running: Yes
