mysql初始化後修改密碼及賦權

在丟失root密碼的時候，可以這樣


方法一：
# /etc/init.d/mysql stop
# mysqld_safe --user=mysql --skip-grant-tables --skip-networking &
# mysql -u root mysql
mysql> UPDATE user SET Password=PASSWORD('newpassword') where USER='root';
mysql> FLUSH PRIVILEGES;
mysql> quit


# /etc/init.d/mysql restart
# mysql -uroot -p
Enter password: <輸入新設的密碼newpassword>


mysql>


更改密碼：
update user set password=PASSWORD('123456') where USER='root';

遠端連線賦權
grant all PRIVILEGES on mysql.* to root@'192.168.166.102' identified by '123456';

grant all PRIVILEGES on *.* to root@'%' identified by 'mysql';
