很早就开始工作了. 但是当我调用kill -9 uwsgi.pid时，无法再次启动uwsgi进程.

It worked early. But when I invoked kill -9 uwsgi.pid I could not start uwsgi process again.

为什么我不能再次启动uwsgi进程?

Why can't I start uwsgi process again?

推荐答案

关键是:

error removing unix socket, unlink(): Permission denied [core/socket.c  line 198]

您(很可能)曾经以root用户身份运行uwsgi实例，并以root用户权限创建了unix套接字文件.

You (very probably) previously run a uwsgi instance as root creating the unix socket file with root permissions.

现在您的实例(改为以www身份运行)无法重新绑定()该套接字，因为它无法取消链接(无权限)

Now your instance (running instead as www) is not able to re-bind() that socket as it is not able to unlink it (no permissions)

只需删除套接字文件，然后重试即可.

Just remove the socket file and retry.
