Mysql5.7.18.1修改用戶密碼報(bào)錯(cuò)ERROR 1054 (42S22):

mysql> update user set password=password(“新密碼”) where user=”用戶名”;
執(zhí)行后報(bào)錯(cuò) 　ERROR 1054(42S22) Unknown column 'password' in ‘field list’

錯(cuò)誤的原因是 5.7版本下的mysql數(shù)據(jù)庫(kù)下已經(jīng)沒(méi)有password這個(gè)字段了，password字段改成了authentication_string

所以請(qǐng)使用一下命令：

mysql -u root -p

Enter password: **
