我希望你能够帮助我将nginx与uwsgi配置起来,在Arch Linux上操作。我有/etc/uwsgi/emperor.ini和/etc/uwsgi/vassals/myapp.ini两个文件。我的emperor.ini如下:
[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
当运行uwsgi.service时,我会得到以下信息:
uwsgi.service - uWSGI Emperor

那段代码?“皇帝统治0个附属国”的原因是它无法查看vassal目录中的myapp.ini文件。这是我在命令行“日志”中收到的信息:

我无论如何都似乎无法让uwsgi运行并看到它的vassals。谢谢。
编辑
好吧,我决定回到命令行,这样我就不必处理日志和pid权限错误,我注意到了一些奇怪的事情。当我写出uwsgi --ini /etc/uwsgi/emperor.ini时,整个过程都可以工作,我可以通过nginx访问网站,非常好,但我在控制台输出中看到了这个:

我开始注意到输出中出现了一些奇怪的行为。最终,我找到了这个配置,让我能够看到我的网站。
emperor.ini
[uwsgi]
emperor = /etc/uwsgi/vassals
master = true
#gid = http
#uid = http
我注释掉了gid和uid,因为如果它们存在,当我尝试连接到我的网站时会得到一个错误的网关响应,并且日志中会警告我uWSGI以root身份运行,您可以使用--uid/--gid/--chroot选项,但我不确定该怎么做。
myapp.ini

wsgi-file = run.py

不知道该怎么办,才能让它不以root权限运行。
