mysql默认root用户没有密码，输入mysql –u root 进入mysql
1、初始化root密码
进入mysql数据库
|
1
|
mysql>update user set password=PASSWORD('123456') where User='root'; |
-- mysql 5.7.19 --
update user set authentication_string=PASSWORD('123456') WHERE User='root';
2、允许mysql远程访问,可以使用以下三种方式:
a、改表。
|
1
2
3
4
|
mysql -u root –pmysql>use mysql;mysql>update user set host = '%' where user = 'root';mysql>select host, user from user; |
b、授权。
例如，你想root使用123456从任何主机连接到mysql服务器。
|
1
|
mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION; |
如果你想允许用户jack从ip为10.10.50.127的主机连接到mysql服务器，并使用654321作为密码
|
1
2
|
mysql>GRANT ALL PRIVILEGES ON *.* TO 'jack'@’10.10.50.127’ IDENTIFIED BY '654321' WITH GRANT OPTION;mysql>FLUSH RIVILEGES |
c:在安装mysql的机器上运行：

//进入MySQL服务器d:mysqlin>mysql -h localhost -u root//赋予任何主机访问数据的权限mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION//使修改生效mysql>FLUSH PRIVILEGES//退出MySQL服务器mysql>EXIT |
