ERROR 1201 (HY000):Could not initialize master info structure的問題 今天在做MySQL主從復制時遇到個ERROR 1201 (HY000): Could not initialize master info structure . 出現這個問題的原因是之前曾做過主從復制！ www.2cto.com 解決方案是：運行命令 stop slave; 成功執行後繼續運行 reset slave; 然後進行運行GRANT命令重新設置主從復制。 具體過程如下： Command代碼 mysql> change master to master_host='127.0.0.1', master_user='user', master_pass word='user', master_log_file='mysql-bin-000202', master_log_pos=553; ERROR 1201 (HY000): Could not initialize master info structure; more error messa ges can be found in the MySQL error log mysql> stop slave; Query OK, 0 rows affected, 1 warning (0.00 sec) mysql> reset slave; Query OK, 0 rows affected (0.00 sec) mysql> change master to master_host='127.0.0.1', master_user='user', master_pass word='user', master_log_file='mysql-bin-000202', master_log_pos=553; Query OK, 0 rows affected (0.11 sec)
