无法通过ini flag启动uwsgi进程
uwsgi --ini file.ini
没有任何uwsgi pids
ps aux | grep uwsgi

error removing unix socket, unlink(): Permission denied [core/socket.c line 198]
bind(): Address already in use [core/socket.c line 230]
它起得很早。 但是当我调用kill -9 uwsgi.pid时,我无法再次启动uwsgi进程。
请告诉我,为什么我可以再次启动uwsgi进程? 感谢
答案 0 :(得分:17)
关键是:删除unix socket时出错,unlink():权限被拒绝[core / socket.c第198行]
您(很可能)以前以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(以www运行)无法重新绑定()该套接字,因为它无法取消链接(无权限)
只需删除套接字文件并重试即可。
答案 1 :(得分:12)
我遇到了一个非常类似的问题,除非删除套接字文件后仍然无法正常工作。事实证明这是因为uWSGI无法创建一个新的(它只存在,因为我自己运行uwsgi)。非常简单的解决方案是chmod
包含套接字文件的目录,允许www
用户在那里创建和修改文件。现在很明显,但也许这将有助于未来可怜的闷棍撞在墙上,因为我今天已经工作了太多时间。
