MySQL 出现 Could not initialize master info structure 修复

 MySQL 设定同步 Replication, 将下述命令拆成两组输入, 如下述:

1.mysql> CHANGE MASTER TO MASTER_HOST='master.example.com', MASTER_USER='repl', MASTER_PASSWORD='repl_password';
2.mysql> CHANGE MASTER TO MASTER_LOG_FILE='mysql-bin.000001', MASTER_LOG_POS=107;
设定 Replication 完成后, start slave 无法?⒍? 出现下述错误讯息:

Could not initialize master info structure, more error messages can be found in the MySQL error log

要怎么解决呢?

下述直接写解法:

4.?: 重新设置 slave, MASTER_LOG_FILE 和 MASTER_LOG_POS 会被清空, 所以需要重新设置.
