MySQL手册版本 5.0.20-MySQL同步(二)
6.4 设置同步
以下描述了如何快速设置MySQL同步服务器。假设你打算同步全部的数据库，并且之前没有设置过。需要关闭master服务器以完成全部的步骤。
本章描述的过程可以用于一个slave的情况，也可以用于多个slave的情况。
这只是一个最直接设置slave的办法，并不是只有一个。例如，已经有了master的数据快照(snapshot)，master已经设置了服务器编号ID(server_id)并且启用了二进制日志，这就无需关闭master或者阻止在master上更新数据了。详情请看"6.9
Replication FAQ"。
想要完全掌握MySQL同步设置，最好把本章全部读完，并且测试在"14.6.1 SQL
Statements for Controlling Master Servers"和"14.6.2 SQL Statements for
Controlling Slave Servers"中提到的全部语句。而且要熟悉各种同步设置选项，详情请看"6.8 Replication Startup
Options"。
注意，这个过程以及后面一些同步SQL语句需要有 SUPER 权限。MySQL 4.0.2以前，则是
PROCESS 权限。
请确认master和slave上都安装了较近的MySQL版本，且这些版本之间要能兼容，在"6.5
Replication Compatibility Between MySQL
Versions"中列出来了。请确认在最新版本中还有存在问题，否则不要报告该bug。
在master上新加一个帐户，slave才能用它来连接。这个帐户必须授予 REPLICATION
SLAVE 权限。如果这个帐户只用于同步(推荐这么做)，那就没必要授予其他权限了。设定你的域是 mydomain.com，想要授权一个帐户 repl 使用密码
