更新:如果我不使用套接字，而是使用127.0.0.1:3031，一切正常.

UPDATE: if I don't use socket and use 127.0.0.1:3031 instead, everything works fine.

Nginx版本是1.6.3，而uwsgi是2.0.11.1

Nginx version is 1.6.3, and uwsgi is 2.0.11.1

/etc/uwsgi.ini:

/etc/uwsgi.ini:

[uwsgi] uid = uwsgi gid = uwsgi pidfile = /run/uwsgi/uwsgi.pid emperor = /etc/uwsgi.d stats = /run/uwsgi/stats.sock emperor-tyrant = true cap = setgid,setuid logto = /var/log/uwsgi.log

/etc/uwsgi.d/daimaduan_preview.ini

/etc/uwsgi.d/daimaduan_preview.ini

[uwsgi] plugin = python,http protocol = uwsgi chdir = /var/www/daimaduan/preview/current master = true processes = 4 threads = 20 socket = /tmp/daimaduan-preview.sock chmod-socket = 666 uid = vagrant gid = vagrant logto = /var/log/daimaduan/preview/uwsgi.log virtualenv = /var/www/daimaduan/preview/venv wsgi-file = deploy.wsgi

/etc/nginx/conf.d/daimaduan.conf

/etc/nginx/conf.d/daimaduan.conf

server { listen 80; server_name example; access_log /var/log/daimaduan/preview/access.log; error_log /var/log/daimaduan/preview/error.log; root /var/www/daimaduan/preview/current/daimaduan; location / { uwsgi_pass unix:/tmp/daimaduan-preview.sock; include uwsgi_params; } }

但是，通过访问 127.0.0.1/，我从nginx收到了错误消息:

However, I got errors from nginx by visiting 127.0.0.1/:

我很确定/tmp/daimaduan-preview.sock确实存在.我还检查了uwsgi日志:

And I am pretty sure /tmp/daimaduan-preview.sock does exist. I also checked uwsgi log:

看起来也很正常.

这里有一些问题:

为什么uid和gid在/etc/uwsgi.d/daimaduan.ini中不生效?

如何更改/tmp/daimaduan-preview.sock的所有权?我尝试了chown-socket但失败了

为什么在/var/log/daimaduan/preview/uwsgi.log中出现No such file or directory错误?

why uid and gid does not take effect in /etc/uwsgi.d/daimaduan.ini?

how to change ownership for /tmp/daimaduan-preview.sock? I tried chown-socket but failed

why did I get No such file or directory errors in /var/log/daimaduan/preview/uwsgi.log?

推荐答案

将daimaduan_preview.ini的套接字文件放入/run而不是/tmp.就像在此答案中一样，您的系统可能使用了命名为空格的临时目录，这意味着每个服务只能看到其/tmp中的文件.

Put the daimaduan_preview.ini's socket file into /run instead of /tmp. Like in this answer, your system probably using namespaced temporary directories, which means every service can only see its own files in /tmp.
