当我在Django应用中运行python manage.py migration时,会发生类似

django.db.utils.OperationalError: (1045, "Access denied for user 'admin'@'localhost' (using password: NO)")
我写了mysql -u root
,错误1045(28000):用户'root'@'localhost'(使用密码:否)的访问被拒绝,并且当我运行服务mysqld start
时,无法启动mysqld.service:发生访问被拒绝错误。此外,当我运行service mysql stop
时,无法停止mysql.service:发生了访问被拒绝错误。我向每个命令添加了sudo,但是同样的错误也发生了。我真的不明白为什么认证错误发生。我该如何解决?我的代码有什么问题?
答案 0 :(得分:1)
在较新的MySQL版本中,您还需要在命令中使用-p
标志:
mysql -u root -p
然后输入密码,您将可以登录。
现在,您可以使用具有密码和其他权限的
admin
创建新用户,并且可以在 settings.py 文件中使用。
答案 1 :(得分:0)
您需要成为root
用户才能运行service mysqld start
或service mysqld start
。
