ERROR 1200（HY000）：服务器未配置为从站;修复配置文件或使用CHANGE MASTER TO

Question

my.cnf部分是

   [mysqld_safe]
   log-error=/var/log/mysqld.log
   pid-file=/var/run/mysqld/mysqld.pid
   log_error = /var/log/mysql_error.log

    server-id = 3;
    log-bin = mysql-bin
    relay-log = prod-relay-bin
    slave-skip-errors =

当我重新启动奴隶给出错误时

  

ERROR 1200（HY000）：服务器未配置为从站;修复   配置文件或使用CHANGE MASTER TO

然后我检查了服务器ID：

mysql> SHOW VARIABLES LIKE 'server_id';

    +---------------+-------+
    | Variable_name | Value |
    +---------------+-------+
    | server_id     | 0     |
    +---------------+-------+

Answer 1

server_id不能设置为0才能使mysql复制正常工作。
