SUSE12-SP2 mysql主主同步

1. 修改两台服务器配置文件

修改主服务器配置文件，增加如下

#vi /etc/my.cnf

[mysqld]

server-id=1

log-bin=mysql-bin

log-slave-updates

binlog-ignore-db = mysql

binlog-ignore-db = information_schema

binlog-ignore-db = performance_schema

replicate-wild-ignore-table = mysql.%

replicate-wild-ignore-table = information_schema.%

replicate-wild-ignore-table = performance_schema.%

expire_logs_days=5

修改从服务器配置文件，增加如下

#vi /etc/my.cnf

[mysqld]
server-id=2

log-bin=mysql-bin

log-slave-updates

binlog-ignore-db = mysql

binlog-ignore-db = information_schema

binlog-ignore-db = performance_schema

replicate-wild-ignore-table = mysql.%

replicate-wild-ignore-table = information_schema.%

replicate-wild-ignore-table = performance_schema.%

expire_logs_days=5

2. 重启mysql服务（两台都需要重启）

#systemctl restart mysqld

3. 配置主主

(1) [FH-CC1]mysql 为主库

FH-CC1

#mysql -p（123456）

mysql> show master status;

FH-CC2

#mysql -p(123456)

mysql> show slave status;

mysql> stop slave;

mysql> change master to master_host='192.168.1.183',master_user='root',master_password='123456',master_log_file='mysql-bin.000001',master_log_pos=154;

mysql> start slave;

mysql> show slave status\G

详细信息如下：

mysql> show slave status\G

(2) [FH-CC2]mysql 为主库

类似的，可以配置FH-CC2上的mysql为主库

FH-CC2

#mysql -p（123456）

mysql> show master status;

FH-CC1

#mysql -p(123456)

mysql> show slave status;

mysql> stop slave;

mysql> change master to master_host='192.168.1.184',master_user='root',master_password='123456',master_log_file='mysql-bin.000001',master_log_pos=154;

mysql> start slave;

mysql> show slave status\G

5. 设置开机自启动（两台都需要）

#vim /etc/init.d/boot.local添加

systemctl start mysql.service
