【MySql Replication】
Replication is asynchronous by default. Depending on the configuration, you can replicate all databases, selected databases, or even selected tables within a database.
To configure a master to use binary log file position based replication, you must enable binary logging and establish a unique server ID. If this has not already been done, a server restart is required.
Note
Ensure that the skip-networking option is not enabled on your replication master. If networking has been disabled, the slave can not communicate with the master and replication fails.
在 /usr/local/mysql/my.cnf 中添加 log-bin 和 server-id 属性。
if you omit server-id (or set it explicitly to its default value of 0), the master refuses any connections from slaves.
在Slave中更新Master信息。
