Mysql 复制不工作

我配置了主从复制，它工作得很好，但5分钟左右就停止工作了！虽然从机状态显示复制正常，但无论我在主机中插入什么，都不会在从机中复制

这是我遵循的原则

只有在从机上运行命令服务mysqld restart时，事情才会再次开始复制

# nano /etc/my.cnf

 server-id = 1
 binlog-do-db=db0
 binlog-do-db=db2
 binlog-do-db=db3
 relay-log = /var/lib/mysql/mysql-relay-bin
 relay-log-index = /var/lib/mysql/mysql-relay-bin.index
 log-error = /var/lib/mysql/mysql.err
 master-info-file = /var/lib/mysql/mysql-master.info
 relay-log-info-file = /var/lib/mysql/mysql-relay-log.info
 log-bin = /var/lib/mysql/mysql-bin

# /etc/init.d/mysqld restart

# mysql -u root -pMorphie5

GRANT REPLICATION SLAVE ON *.* TO 'xgears'@'137.116.213.135' IDENTIFIED BY 'Morphie5';
 FLUSH PRIVILEGES;
 FLUSH TABLES WITH READ LOCK;
 SHOW MASTER STATUS;
mysql>exit;

#  mysqldump  -u root  --all-databases --master-data > /root/dbdump.db

mysql> UNLOCK TABLES;
mysql> quit;

scp /root/dbdump.db root@137.116.213.135:/root/

位于从属服务器上，服务器ID与Master@BerndBuffen我已添加我的代码请检查复制停止时请发布从机“show slave status\G”的错误消息我已将其添加到上面。屏幕截图显示的是当事情没有复制，但显示从属状态正常时
