一、服务器配置
主库：192.168.204.132
vim /etc/my.cnf
server-id= 1
log-bin=mysql-bin
binlog_format=mixed
#需要同步的二进制数据库名
binlog-do-db=test
#不同步的二进制数据库名
binlog-ignore-db=mysql
binlog-ignore-db=performance_schema
#可选参数
sync-binlog = 1
#日志保留天数
expire_logs_days = 7
从库：192.168.204.134
vim /etc/my.cnf
server-id=2
log-bin=mysql-bin
binlog_format=mixed
#不需要复制的数据库
replicate-ignore-db=mysql
replicate-ignore-db=performance_schema
#需要复制的数据库
replicate-do-db=test
#可选参数
sync-binlog = 1
expire_logs_days = 7
二、设置主从
主库：
mysql> SHOW MASTER STATUS;
+------------------+----------+--------------+--------------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+--------------------------+
| mysql-bin.000026 | 302 | test | mysql,performance_schema |
+------------------+----------+--------------+--------------------------+
mysql>GRANT REPLICATION SLAVE ON *.* TO 'root'@'192.168.204.134' IDENTIFIED BY '123456';
mysql>FLUSH PRIVILEGES;

从库：
mysql> CHANGE MASTER TO MASTER_HOST='192.168.204.132',MASTER_USER='root', MASTER_PASSWORD='123456',MASTER_LOG_FILE='mysql-bin.000026',MASTER_LOG_POS=302;
#上面参数注意对照主库
mysql> slave stop;
mysql> slave start;
mysql> show slave status \G;

如出现 Last_Error: Unable to load replication GTID slave state from mysql.gtid_slave_pos: Table 'mysql.gtid_slave_pos' doesn't 这个错误
解决办法为：
use mysql；
drop table mysql.gtid_slave_pos；

CREATE TABLE gtid_slave_pos (

   `domain_id` int(10) unsigned NOT NULL,
   `sub_id` bigint(20) unsigned NOT NULL,
   `server_id` int(10) unsigned NOT NULL,
   `seq_no` bigint(20) unsigned NOT NULL,
   PRIMARY KEY (`domain_id`,`sub_id`)
 ) ENGINE=MyISAM DEFAULT CHARSET=utf8 COMMENT='Replication slave GTID state';

查看 slave 状态
到此结束
