error removing unix socket, unlink(): Permission denied [core/socket.c line 198]
bind(): Address already in use [core/socket.c line 230]
它很早就起作用了。
但是当我调用kill -9 uwsgi.pid我无法再次启动 uwsgi 进程。
为什么我无法再次启动 uwsgi 进程？
关键是：
error removing unix socket, unlink(): Permission denied [core/socket.c line 198]
您（很可能）之前以 root 身份运行 uwsgi 实例，创建具有 root 权限的 unix 套接字文件。
现在您的实例（作为 www 运行）无法重新绑定（）该套接字，因为它无法取消链接（没有权限）
只需删除套接字文件并重试即可。
