SUSE12-SP2 mysql主主同步
1. 修改兩臺伺服器配置檔案
修改主伺服器配置檔案，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 |
修改從伺服器配置檔案，增加如下
#vi /etc/my.cnf
| [mysqld] 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. 重啟mysql服務（兩臺都需要重啟）
#systemctl restart mysqld
3. 配置主主
(1) [FH-CC1]mysql 為主庫
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 |
詳細資訊如下：
mysql> show slave status\G

(2) [FH-CC2]mysql 為主庫
類似的，可以配置FH-CC2上的mysql為主庫
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. 設定開機自啟動（兩臺都需要）
#vim /etc/init.d/boot.local新增
systemctl start mysql.service
