mysql主从同步复制错误解决一例

复制代码 代码如下:

Last_IO_Error: Fatal error: The slave I/O thread stops because master and slave have equal MySQL server ids; these ids must be different for replication to work (or the --replicate-same-server-id option must be used on slave but this does not always make sense; please check the manual before using it).

复制代码 代码如下:

mysql> show variables like 'server_id';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| server_id | 1 |
+---------------+-------+
1 row in set (0.00 sec)

复制代码 代码如下:

mysql> set global server_id=2; #此处的数值和my.cnf里设置的一样就行
mysql> slave start;

复制代码 代码如下:

find / -name "my.cnf"
