Uwsgi 从 root 启动，但不作为服务启动

Uwsgi 从 root 启动，但不作为服务启动

我已经为 flask 网站设置了 nginx + uwsgi。

这是我的 nginx

server {
listen 80;
server_name _;

location /static/ {
    alias /var/www/site/app/static/;
}

location / {
    uwsgi_pass 127.0.0.1:5080;
    include uwsgi_params;
}
}

这是我的 uwsgi config.xml

<uwsgi>
<socket>127.0.0.1:5080</socket>
<autoload/>
<daemonize>/var/log/uwsgi_webapp.log</daemonize>
<pythonpath>/var/www/site/</pythonpath>
<module>run:app</module>
<plugins>python27</plugins>
<virtualenv>/var/www/venv/</virtualenv>
<processes>1</processes>
<enable-threads/>
<master />
<harakiri>60</harakiri>
<max-requests>2000</max-requests>
<limit-as>512</limit-as>
<reload-on-as>256</reload-on-as>
<reload-on-rss>192</reload-on-rss>
<no-orphans/>
<vacuum/>
</uwsgi>

当我尝试启动 uwsgi 服务（service uwsgi start）时，它显示正常，但是没有 uwsgi 进程，并且我在日志中看到以下内容：

*** Starting uWSGI 1.0.3-debian (64bit) on [Fri Oct 25 00:43:13 2013] ***

uwsgi socket 0 bound to TCP address 127.0.0.1:5080 fd 6
bind(): Permission denied [socket.c line 107]

但是当我以 root 身份启动 uwsgi 时

uwsgi --socket 127.0.0.1:5080 --module run --callab app --harakiri 15 --harakiri-verbose --logto2 tmp/uwsgi.log

它启动正常，重新启动 nginx 后我就可以访问网站了。

这可能是一个什么问题？

这真的很愚蠢。我花了几个小时试图弄清楚这一点，并在我发布这篇文章后立即找到了原因。有一个漏洞这让我尝试将 uid 和 gid 添加到配置中：

<uwsgi>
<socket>127.0.0.1:5080</socket>
<autoload/>
<daemonize>/var/log/uwsgi_webapp.log</daemonize>
<pythonpath>/var/www/site/</pythonpath>
<module>run:app</module>
<plugins>python27</plugins>
<virtualenv>/var/www/gsk/</virtualenv>
<processes>1</processes>
<uid>www-data</uid>
<gid>www-data</gid>
<enable-threads/>
<master />
<harakiri>60</harakiri>
<max-requests>2000</max-requests>
<limit-as>512</limit-as>
<reload-on-as>256</reload-on-as>
<reload-on-rss>192</reload-on-rss>
<no-orphans/>
<vacuum/>
</uwsgi>

添加这些之后，它启动了，重新启动 nginx 后它就可以正常工作了。
