Mysql數據庫帳戶權限設置

1.修改mysql數據庫的root密碼:

修改 數據庫.表名 SET password=加密(‘密碼’) where user=’root’;

UPDATE mysql.user SET password = PASSWORD('123') WHERE user='root'; flush PRIVILEGES;

備註: flush PRIVILEGES; 表示:刷新數據表,不添加,修改的sql語句不會當即生效

2.添加mysql數據庫的訪問用戶  用戶名:cmstop 密碼:自定義 (多服務器部署時添加前臺的內網ip做爲訪問mysql表user中的host字段,能夠防止外網的訪問)

GRANT ALL PRIVILEGES ON testdb.* TO 'testuser'@'localhost' IDENTIFIED BY '123'; flush PRIVILEGES;

GRANT ALL PRIVILEGES ON testdb.* TO 'testuser'@'127.0.0.1' IDENTIFIED BY '123'; flush PRIVILEGES;

GRANT ALL PRIVILEGES ON testdb.* TO 'testuser'@'%' IDENTIFIED BY '123'; flush PRIVILEGES;

3.設置只讀權限

GRANT SELECT ON testdb.* TO 'testuser'@'192.168.0.%' IDENTIFIED BY '123'; flush PRIVILEGES;
