解决mysql slave同步问题

  解决办法:
  1.首先停掉Slave服务:slave stop;
  2.到主服务器上查看主机状态:
  记录File和Position对应的值。
  mysql> show master status;
  +------------------+-----------+--------------+------------------+
  | File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
  +------------------+-----------+--------------+------------------+
  | mysql-bin.000020 | 135617781 | | |
  +------------------+-----------+--------------+------------------+
  1 row in set (0.00 sec)
  3.到slave服务器上执行手动同步:
  mysql> change master to
  > master_host='master_ip',
  > master_user='user',
  > master_password='pwd',
  > master_port=3307,
  > master_log_file='mysql-bin.000020',
  > master_log_pos=135617781;
  4.启动slave
  slave start;
  5.查看slave状态
  show slave status \G;
