MySQL启动时的初始执行文件的使用
MySQL启动时的初始执行文件的使用
可以在配置文件里指定mysql启动以后初始执行的SQL文件, 其语法是:
在[mysqld]或者[server]下指定:
init-file=D:\mysql-5.5.28-winx64\abc.sql, 后边为具体的sql文件值
为了示例:
abc.sql为:
- use test;
- begin;
- create table if not exists t123(id int);
- insert into t123 values(1);
- insert into t123 values(2);
- select * from t123;
- -- drop table t123;
- end;
启动完mysql以后,得到查询:
- mysql> use test;
- Database changed
- mysql> select * from t123;
- +------+
- | id |
- +------+
- | 1 |
- | 2 |
- +------+
- 2 rows in set (0.00 sec)
第二次启动以后,得到结果:
- Welcome to the MySQL monitor. Commands end with ; or \g.
- Your MySQL connection id is 2
- Server version: 5.5.28 MySQL Community Server (GPL)
- Copyright (c) 2000, 2012, Oracle and/or its affiliates. All rights reserved.
- Oracle is a registered trademark of Oracle Corporation and/or its

- Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
- mysql> use test;
- Database changed
- mysql> select * from t123;
- +------+
- | id |
- +------+
- | 1 |
- | 2 |
- | 1 |
- | 2 |
- +------+
- 4 rows in set (0.00 sec)
当然,我们要注意的是,这个init_file的内容是有要求的:
1. 确保你的mysqld 编译的时候没有加 --disable-grant-options 开关。
2. 确保init-file指定的脚本每行是一个具体的可以执行的语句。
