MySQL安全值守常用语句
MySQL的安全值守通常指的是维护数据库安全性、性能、完整性的一系列操作和策略。以下是一些常用的MySQL安全维护语句:
- 修改root密码:
SET PASSWORD FOR 'root'@'localhost' = PASSWORD('new_password');
- 删除匿名用户:
DELETE FROM mysql.user WHERE User = '';
- 移除未授权的用户:
DELETE FROM mysql.user WHERE Host NOT IN ('localhost', '127.0.0.1');
- 刷新权限使更改生效:
FLUSH PRIVILEGES;
- 加强密码策略:
SET GLOBAL validate_password_policy = 1;
SET GLOBAL validate_password_length = 8;
- 移除不安全的引擎(例如MyISAM):
DELETE FROM mysql.user WHERE User = 'username' AND Host = 'host' AND (Select_priv = 'N' OR Insert_priv = 'N' OR Update_priv = 'N' OR Delete_priv = 'N' OR Create_priv = 'N' OR Drop_priv = 'N');
- 审计日志:
INSTALL PLUGIN audit_log SONAME 'audit_log.so';
确保在执行这些操作之前,您已经备份了数据库,并且具备相应的权限。
