Mysql主从同步 异常Slave_SQL_Running: No

Posted 2020-11-22 Leader.Z

在刚搭建好的mysql主从节点上对从节点进行操作，导致同步异常：报错如下：

从节点执行：

mysql> show slave statusG;

解决方法1：

Slave_SQL_Running: No
1.程序可能在slave上进行了写操作

2.也可能是slave机器重起后，事务回滚造成的.

一般是事务回滚造成的：
解决办法：
mysql> stop slave ;
mysql> set GLOBAL SQL_SLAVE_SKIP_COUNTER=1;
mysql> start slave ;

解决办法二、

首先停掉Slave服务：slave stop
到主服务器上查看主机状态：
记录File和Position对应的值

进入master

mysql> show master status;
+------------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+------------------+-------------------+
| mysql-bin.000003 | 32168 | test | mysql | |
+------------------+----------+--------------+------------------+-------------------+
1 row in set (0.00 sec)

 

然后到slave服务器上执行手动同步：

mysql> change master to 
> master_host=‘192.168.43.10‘,
> master_user=‘db‘, 
> master_password=‘123456‘, 
> master_port=3306, 
> master_log_file=‘mysql-bin.000003‘, 
> master_log_pos=32168 ;
mysql> start slave ;
