Mysql5.7.18.1修改用戶密碼報錯ERROR 1054 (42S22): Unknown Column 'Password' In 'Field List'解決辦法

本意向修改一個用戶的密碼，網上搜到的命令爲如下

1	mysql> update user set password=password(“新密碼”) where user=”用戶名”;

執行後報錯 　ERROR 1054(42S22) Unknown column 'password' in ‘field list’

錯誤的原因是 5.7版本下的mysql數據庫下已經沒有password這個字段了，password字段改成了authentication_string

所以請使用一下命令：

>mysql -u root -p
Enter password: ********
