 mysql 5.7  修改 密码 报错？

ERROR 1054(42S22) Unknown column 'password' in ‘field list’
原因：
5.7 版本下的mysql数据库下已经没有password这个字段了，password字段改成了authentication_string

Mysql 忘记密码；

、停止 mysql
# /etc/init.d/mysql stop

、跳过验证登陆进入
# mysqld_safe --user=mysql --skip-grant-tables --skip-networking &

执行之后 另开一个窗口；

root@datanode3: ~# mysql -u root mysql
