Mysql master-slave synchronization skip error method:

1. Skip the specified number of transactions:

mysql>slave stop;
mysql>SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 1        #跳过一个事务
mysql>slave start

2. Modify the mysql configuration file and use the slave_skip_errors parameter to skip all errors or errors of the specified type

vi /etc/my.cnf
[mysqld]
#slave-skip-errors=1062,1053,1146  #跳过指定error no类型的错误
#slave-skip-errors=all  #跳过所有错误

Example: below Simulate an error scenario

Environment (a configured master-slave replication environment)

master database IP: 192.168.247.128

slave database IP: 192.168.247.130

mysql version: 5.6.14

binlog-do-db = mydb

Execute the following statement on the master:

mysql>use mysql;
mysql>create table t1 (id int);
mysql>use mydb;
mysql>insert into mysql.t1 select 1;

View the replication status on the slave

mysql> show slave status\G
