+# MySQL 配置文件
+
+- `master.cnf`是主节点的配置文件
+- `slave.cnf`是从节点的配置文件
+
+注意`binlog-do-db`需要分两行来写，不能直接使用`,`分隔，官方文档有说明，`,`是可以作为数据库名字包含在其中的，也就是说：
+```bash
+binlog-do-db=test0,test1
+```
+会被看作是一个叫`test0,test1`的库，而不是一个叫`test0`，一个叫`test1`的库。

+# mysqldump 导出文件
+
+使用时直接使用`mysqldump`导入即可。
+
+首先创建好两个库：
+```mysql
+create database test0;
+create database test1;
+```
+接着导入：
+```bash
+mysqldump -u root -p < master.db
+```
