如何解决部署MySql主从遇到的部分问题？

一、ERROR 29 (HY000): File ‘/log/mysql/slave_relaylog.index’ not found
解决办法：文件权限不对 chown mysql:mysql mysql-slow.log

二、ERROR 1201 (HY000): Could not initialize master info structure; more error messages can be found in the MySQL error log

reset slave;
change master to master_host=’ip’, master_user=’replication’, master_password=’wqvbkaqj’,master_log_file=’updatelog.000003′, master_log_pos=98;

三、Last_IO_Error: error connecting to master ‘scol_repc@125.64.41.136:3306’ – retry-time: 60 retries: 86400

发现是用户名输错了
