您好我正在与一些人合作开展一个项目。我们正在使用django 1.9我的mysql和有人设置django来连接mysql，然后为我们其他人编写了关于我们需要下载什么来连接python和mysql的说明。我正确安装了mysql但是我在访问数据库时遇到了问题。我们都假设有权访问数据库，但即使我只是在终端输入mysql django.db.utils.OperationalError: (1045, "Access denied for user 'django'@'localhost' (using password: YES)")并输入ERROR 1045 (28000): Access denied for user 'stevenJing'@'localhost' (using password: NO)我得到mysql -u root -p，我仍然会获得ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES) python3 manage.py runserver }。我不确定我需要做些什么来解决这个问题我甚至无法做 Performing system checks...

因为我得到一个很大的错误。

click设置数据库的人是MySQL的新手，我也是如此，如果有人从我们的git仓库中提取或克隆，他们怎么能得到它，他们可以访问数据库。
答案 0 :(得分：1)
如果人们提取您的代码，并且您希望他们访问您的数据库，那么他们可能不应该使用＆＃34; localhost。＆＃34;如果您在本地主机上运行时遇到此错误，那么这是一个权限问题。
要做的第一件事是看看是否可以使用命令行MySQL或其他MySQL客户端使用这些凭据登录。
我很多都会遇到这类错误（不幸的是），这通常是因为我没有在MySQL中正确添加用户。我注意到只是把'＆＃39;％＆＃39;不考虑localhost，我通常需要添加＆＃39; user＆＃39; @＆＃39; localhost＆＃39;除了用户＆＃39; @＆＃39;％＆＃39;授予用户权限时。
编辑：为了授予权限，您需要以root用户身份登录mysql，通常您会使用以下内容：
% mysql -u root -P mysql
＆＃34; -P＆＃34;意味着你必须提供root / admin密码，最后一个＆＃34; mysql＆＃34;是要使用的架构。显然，您需要管理员访问才能执行此操作。
然后，在更新版本的MySQL中，首先创建用户：
> create user 'stevenJing'@'localhost' identified by 'password';
这实际上是一个不同于＆＃39; stevenJing＆＃39; @＆＃39;％＆＃39;的用户，所以如果您要从localhost和远程主机连接这两个用户，那么实际上你需要这两个用户
然后您需要为该用户授予权限：
> grant all privileges on <schema>.* to 'stevenJing'@'localhost';
架构显然是你的Django架构（上面的Django设置中的lolProject）。此外，当然，要授予该用户从其他地方登录的权限：
> grant all privileges on <schema>.* to 'stevenJing'@'%';
答案 1 :(得分：1)
此错误是因为django用户无权访问lolProject数据库。您可以使用GRANT命令纠正此问题。 django用户需要很多权限，因为它需要创建和删除表作为迁移的一部分，所以像这样的人应该这样做。
GRANT ALL ON lolproject.* TO 'django'@'localhost';
更新：通常，您可以通过以mysql -u root打开mysql控制台来执行此操作，其中root是默认安装的帐户，通常没有与之关联的密码。
现在，如果每个人都在他们的计算机上安装了一个mysql服务器，那就没关系了。如果每个人都连接到同一个compupter，它应该是
GRANT ALL ON lolproject.* TO 'django'@'%';
由于从您的回购中提取的每个人都需要访问权限，因此您应该在settings.py
你考虑过使用sqlite吗？它几乎不需要任何设置，每个从您的仓库克隆或拉出的人都会获得当前数据库的副本（如果它已被添加到仓库中）。
