mysql主存binlog同步

1. 修改主库my.ini
   

2. 修改存库配置文件
   

注意

主从的server-id 不能重复

3. 在主mysql里面配置从库的用户信息

   grant replication slave on *.* to 'backup_user' @'%' identified by 'backup@ghsx2019';
   

4. 在从库的mysql中配置：

   change master to master_host='172.17.227.217',
   master_port=12099,
   master_user='slave',
   master_password='elecidenti!123',
   master_log_file='master-bin.000006',
   master_log_pos=180069
   

如果出现：Got fatal error 1236 from master when reading data from binary log

需要在主库中执行：

flush logs;
show master status;

然后去从库设置下：

CHANGE MASTER TO MASTER_LOG_FILE='testdbbinlog.000008',MASTER_LOG_POS=107;
slave start;
show slave status \G
