只能以root身份运行uwsgi

Question

我准备将nginx/uwsgi与烧瓶用于我正在开发的网站，但我遇到了问题。注意网站本身运行良好使用烧瓶的调试：5000端口，但我想现在投入生产。解释我做了什么。

这是一个的Linode的Ubuntu 12.04LTS服务器，我安装了它这样的：

# install nginx 
sudo apt-get install python-software-properties 
sudo add-apt-repository ppa:nginx/stable 
sudo apt-get update 
sudo apt-get upgrade --show-upgraded 
sudo apt-get install nginx-full 
# installing uwsgi 
sudo apt-get install build-essential python-dev libxml2-dev 
sudo apt-get install libc6 libexpat1 libgd2-xpm libgeoip1 libpam0g libpcre3 libssl1.0.0 libxml2 libxslt1.1 zlib1g 
sudo pip install uwsgi 
# python basics 
sudo apt-get install python-pip build-essential python-dev 
sudo pip install virtualenv 
sudo pip install virtualenvwrapper 
sudo mkdir -p /srv/www/li/ 
cd /srv/www/li/ 
virtualenv venv 
source /srv/www/li/venv/bin/activate 
pip install flask 

然后我开始配置一切，但我已经运行到与uwsgi麻烦（没关系NGINX，这将是。下一步

sudo nano /etc/uwsgi/apps-available/li.xml 

    <uwsgi> 
    <plugin>python</plugin> 
    <socket>/run/uwsgi/app/li.socket</socket> 
    <chmod-socket>666</chmod-socket> 
    <chdir>/srv/www/li</chdir> 
    <pythonpath>/srv/www/li</pythonpath> 
    <virtualenv>/srv/www/li/venv</virtualenv> 
    <module>li</module> 
    <wsgi-file>/srv/www/li/li.py</wsgi-file> 
    <callable>app</callable> 
    <master/> 
    <processes>4</processes> 
    <harakiri>60</harakiri> 
    <reload-mercy>8</reload-mercy> 
    <cpu-affinity>1</cpu-affinity> 
    <stats>/tmp/stats.socket</stats> 
    <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> 

sudo ln -s /etc/uwsgi/apps-available/li.xml /etc/uwsgi/apps-enabled/li.xml 

但是，如果我运行它，我得到：

uwsgi --xml /etc/uwsgi/apps-enabled/li.xml

任何人都可以请帮助我吗？由于WWW的数据是www数据组中，他跑了，我尝试了一些东西：

sudo usermod -a -G www-data $USER 
sudo chown -R $USER:www-data /srv/www/li 
sudo chmod -R g+r+w+x /srv/www/li 
sudo chown -R $USER:www-data /etc/uwsgi/apps-enabled 
sudo chmod -R g+r+w+x /etc/uwsgi/apps-enabled 
sudo chown -R $USER:www-data /run/uwsgi/app 
sudo chmod -R g+r+w+x /run/uwsgi/app 

但真的没有帮助。我也尝试了一个tcp端口，而不是unix/run/uwsgi/app/port，这两个端口没有任何区别... 这让我很疯狂:(我希望有人对这里发生的事情有一点线索

亲切的问候，

岩溶

Answer 1

好，后来编辑后，我检查的目录和插座：在服务器重新启动它仍然给了埃罗但不同的一个后目录不存在（不再）;我瘦k它必须使用原始apt-get安装与我以后的pip安装...仍然有问题与python插件，但会检查是否需要为nginx或如果它将工作没有它... 8小时的工作在复位，德哦;）

@bearrito： 在我把插座的tmp目录结束，以避免人权问题：

<uwsgi> 
     <uid>www-data</uid> 
     <gid>www-data</gid> 
    <plugin>python</plugin> 
    <socket>/tmp/li.socket</socket> 
    <chmod-socket>666</chmod-socket> 
    <chdir>/srv/www/li</chdir> 
    <pythonpath>/srv/www/li</pythonpath> 
    <virtualenv>/srv/www/li/venv</virtualenv> 
    <module>li</module> 
    <wsgi-file>/srv/www/li/li.py</wsgi-file> 
    <callable>app</callable> 
    <master/> 
    <processes>2</processes> 
    <pidfile>/tmp/li.pid</pidfile> 
    <harakiri>120</harakiri> 
    <reload-mercy>8</reload-mercy> 
    <cpu-affinity>1</cpu-affinity> 
    <stats>/tmp/stats.socket</stats> 
    <max-requests>2000</max-requests> 
    <limit-as>2048</limit-as> 
    <reload-on-as>2048</reload-on-as> 
    <reload-on-rss>1024</reload-on-rss> 
    <no-orphans/> 
    <vacuum/> 
</uwsgi> 

我希望这有助于！

Answer 2

这一直是我在google上的第一个结果，而且这个页面对我来说相对没有帮助，所以我会添加我的答案，即使它在回顾过程中显而易见。

我的问题是我的统计套接字的权限问题。如果您更改了uWSGI配置的uid或gid参数，请确保您或者chmod或rm所有旧套接字/ pid，以及它们的父文件夹。

Answer 3

对我来说，解决办法是删除/var/run/uwsgi/.sock和

chmod 775 /var/run/uwsgi 
chmod 777 /var/log/uwsgi 

或任何你uwsgi文件。

Answer 4

在我来说，我是想放置.sock文件中/vagrant目录，这是虚框的一台机器安装文件夹，不利于远远超过读取和写入。

放置.sock文件的virtualbox以外挂载点优选在/tmp的FHS说：/var/run
