先登入:mysql -h 192.168.5.116 -P 3306 -u root -p123456
首次登陸無密碼命令:mysql -h 192.168.5.116 -P 3306 -u root
修改密碼(推薦使用方法3):
方法1: 用SET PASSWORD命令
mysql -u root
mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpass');
方法2:用mysqladmin
mysqladmin -u root password "newpass"
如果root已經設定過密碼,採用如下方法
mysqladmin -u root password oldpass "newpass"
方法3: 用UPDATE直接編輯user表
mysql -u root
mysql> use mysql;
mysql> UPDATE user SET Password = PASSWORD('newpass') WHERE user = 'root';
mysql> FLUSH PRIVILEGES;
在丟失root密碼的時候,可以這樣
mysqld_safe --skip-grant-tables&
mysql -u root mysql
mysql> UPDATE user SET password=PASSWORD("new password") WHERE user='root';
mysql> FLUSH PRIVILEGES;
設定IP訪問
mysql>use mysql;
mysql>select host,user from user where user='root';
mysql>update user set host = '%' where user ='root' and host='::1';
mysql> SET PASSWORD FOR 'root'@'%' = PASSWORD('newpass'); //設定密碼
mysql>flush privileges;
mysql>quit
