mysql远程无法登陆解决办法_MySQL
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%'IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
ALL PRIVILEGES表示所有的权限
myuser表示你要新增的mysql用户
%表示可以从所有的ip地址访问这个mysql数据库,也可以指定ip地址,比如root的默认ip地址是localhost和127.0.0.1.
所以root默认只能在mysql的安装机子上连接。
mypassword表示你要新增的用户的密码
例子:
假如现在我的mysql是安装在118.114.245.44上面
GRANT ALL PRIVILEGES ON *.* TO 'dade'@'118.114.245.55'IDENTIFIED BY '123456' WITH GRANT OPTION;
那么只有在118.114.245.55这个机子上才可以通过
用户名:dade
密码:123456
url:118.114.245.44
来访问数据库,及时在数据库的安装机子118.114.245.44也是不可以访问数据库的。
同理,默认的root用户是这样创建的:
GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost'IDENTIFIED BY 'root' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'127.0.0.1'IDENTIFIED BY 'root' WITH GRANT OPTION;
所以只能通过本机的localhost和127.0.0.1才可以访问数据库!
