Master-Master(雙主)

1、測試環境

Master/Slave???????????????????????? ? Master1/Slave1

IP?? ?192.168.1.13???????????????????????? ?192.168.1.10

為了保持干凈的環境：兩邊服務器

rm -rf /var/lib/mysql/*

service mysqld restart

IP:192.168.1.13

IP:192.168.1.10

2、主服務器授權

分別在Master/Slave和Master1/Slave1上創建一個用戶并授予相應權限。

mysql> grant replication slave on *.* to repli@'192.168.1.13′ identified by '123′;

mysql> grant replication slave on *.* to srepli@'192.168.41.189′ identified by '123′;

然后退出mysql控制臺，停止mysql服務：

mysql> \q

3、配置Mysql主配置文件/etc/my.cnf

在/etc/my.cnf配置文件[mysqld]模塊添加如下參數

Master/Slave(192.168.1.13):

[root@bogon ~]# vim /etc/my.cnf

server-id??????????? = 1

log-bin????????????? = mysql-bin

master-host????????? = 192.168.1.13

master-user????????? = srepli

master-password????? = 123

master-port????????? = 3306

replicate-ignore-db? = mysql

Master1/Slave1(192.168.1.10):

[root@repli1 ~]# vim /etc/my.cnf

server-id???????? = 2

log-bin?????????? = mysql-bin

master-host?????? = 192.168.1.10

master-user?????? = repli

master-password?? = 123

master-port?????? = 3306

replicate-ignore-db???? = mysql

4、查看同步狀態

service mysqld restart //兩邊服務器執行

在Master1/Slave1上查看

mysql> show slave status\G

Slave_IO_Running: Yes

Slave_SQL_Running: Yes

在master/Slave上查看：

mysql> show slave status\G

Slave_IO_Running: Yes

Slave_SQL_Running: Yes

注：如果沒有先啟動的服務器Slave_IO_Running: NO mysql> slave stop; mysql> slave start; mysql> show slave status\G 兩邊服務器建庫，建表，插入語句
