Uwsgi皇帝没有附庸

Question

我正在尝试设置 nginx 以使用 uwsgi，我在 Arch Linux 上。我有 /etc/uwsgi/emperor.ini 和 /etc/uwsgi/vassals/myapp.ini。我的 Emperor.ini 看起来像：

[uwsgi]
emperor = /etc/uwsgi/vassals
emperor-pidfile = /run/uwsgi/uwsgi.pid
uid = http
gid = http
logto = /var/log/uwsgi/uwsgi.log

myapp.ini

[uwsgi]
chdir = /srv/http/myapp/src/
wsgi-file = run.py
callable = app
processes = 4
threads = 2
offload-threads = 2
stats =  127.0.0.1:9191
max-requests = 5000
master = True
vacuum = True
socket = 127.0.0.1:3031
enable-threads = true
harakiri = 60
logto = /var/log/uwsgi/myapp.log

uwsgi.service [for systemd]

[Unit]
Description=uWSGI Emperor
After=syslog.target

[Service]
PIDFile=/run/uwsgi/uwsgi.pid
ExecStartPre=/bin/mkdir -p /run/uwsgi
ExecStartPre=/bin/chown http:http /run/uwsgi
ExecStart=/usr/bin/uwsgi --ini /etc/uwsgi/emperor.ini
Restart=always
Type=notify
StandardError=syslog
NotifyAccess=main

[Install]
WantedBy=multi-user.target

然而，当 uwsgi.service 运行时，我得到：

uwsgi.service - uWSGI Emperor
   Loaded: loaded (/etc/systemd/system/uwsgi.service; disabled)
   Active: active (running) since Sun 2014-02-02 04:37:04 PST; 34min ago

Feb 02 04:37:04 MyMachine systemd[1]: Started uWSGI Emperor.

就在那里？ “皇帝正在治理 0 个 vassals”由于某种原因它不会查看 vassal 目录中的 myapp.ini。这是我在命令行“日志”中得到的：

无论我做什么，我似乎都无法让 uwsgi 运行并查看它的附庸。谢谢。

编辑

好的，所以我决定回到命令行，这样我就不必处理日志和 pid 权限错误，我发现了一些奇怪的东西。当我写出 uwsgi --ini /etc/uwsgi/emperor.ini 时，整个工作正常，我可以通过 nginx 访问该站点，很漂亮，但是我在控制台输出中看到了这个：

我开始注意到输出中有一些奇怪的球行为。我终于找到了这个配置，让我可以看到我的网站。

皇帝.ini

[uwsgi]
emperor = /etc/uwsgi/vassals
master = true
#gid = http
#uid = http

我注释掉了 gid 和 uid，因为当我尝试连接到我的网站时，我得到了一个错误的网关响应，它在日志中警告我 uWSGI 作为 root 运行，你可以使用 -- uid/--gid/--chroot 选项 但我不知道该怎么办。

myapp.ini

[uwsgi]
chdir = /srv/http/myapp/src/
wsgi-file = run.py
callable = app
processes = 4
threads = 2
offload-threads = 2
stats =  127.0.0.1:9191
max-requests = 5000
master = true
vacuum = true
socket = 127.0.0.1:3031
harakiri = 60

uwsgi.service

[Unit]

[Service]

Restart=always
KillSignal=SIGQUIT
Type=notify
StandardError=syslog

[Install]
WantedBy=multi-user.target

不知道如何以 root 身份运行它。
