Question

我已经在NGINX上部署了我的应用程序。而且我的error.log充满了：

upstream timed out (110: Connection timed out) while reading upstream, client: 10.107.46.176, server: myApp, request: "GET /myApp/Home/index.load HTTP/1.1", upstream: "uwsgi://unix:///tmp/web2py.socket:", host: "myApp.eng.home.com", referrer: "http://myApp.eng.home.com/"

我已经部署了Postgres数据库。这就是index.html页面的外观：

<div class="clicks">{{=LOAD(c='Home',f='index',extension='load',ajax=True,timeout=30000,times=3)}}
                                {{pass}}
                            </div>

这是index.load页面：

{{=numHits}}

这是我的Home.py控制器：

def index():
    numHits = db(db.opStatus.id > 0).count()
    return dict(numHits=numHits)

这在火箭服务器上运行良好，只有在NGINX出现故障的情况下。请为此提供帮助。

由于我的声誉不允许评论您的问题，因此我不得不滥用回答部分，以免遇到麻烦：

自从我使用NGINX部署web2py应用程序以来，所有问题都基于uWSGI的错误配置。因此，我的首要建议是检查您的uWSGI installation and configuration。尤其要检查emperor.uwsgi.service，uwsgi / web2py.ini和uwsgi-emperor.conf。

此外，可能还有另一个web2py安装目录，默认情况下假定该目录为“ / home / www-data / web2py。在这种情况下，您必须调整nginx / sites-available / web2py。

最后，检查已安装web2py的用户。必须在nginx / nginx.conf

中正确配置该用户

希望这些提示可以帮助您解决问题。如果没有，请如上所述发布您的配置文件。

其他信息：

感谢您提供配置文件。我已经将它们与我的配置进行了比较，看起来还不错。

但是我有点困惑你手动启动皇帝。在我的配置中，这是由/ etc / nginx / sites-available / web2py中配置的Nginx服务器完成的，如下所示：

# file /etc/nginx/sites-available/web2py
server {
    listen          80;
    server_name     $hostname;
    ###to enable correct use of response.static_version
    location ~* ^/(\w+)/static(?:/_[\d]+\.[\d]+\.[\d]+)?/(.*)$ {
        alias /home/www-data/web2py/applications/$1/static/$2;
        expires max;
        ### if you want to use pre-gzipped static files (recommended)
        ### check scripts/zip_static_files.py and remove the comments
        # include /etc/nginx/conf.d/web2py/gzip_static.conf;
    }
    ###
    ###if you use something like myapp = dict(languages=['en', 'it', 'jp'], default_language='en') in your routes.py
    #location ~* ^/(\w+)/(en|it|jp)/static/(.*)$ {
    #    alias /home/www-data/web2py/applications/$1/;
    #    try_files static/$2/$3 static/$3 =404;
    #}
    ###

    location / {
        #uwsgi_pass      127.0.0.1:9001;
        uwsgi_pass      unix:///tmp/web2py.socket;
        include         uwsgi_params;
        uwsgi_param     UWSGI_SCHEME $scheme;
        uwsgi_param     SERVER_SOFTWARE    nginx/$nginx_version;
        ###remove the comments to turn on if you want gzip compression of your pages
        # include /etc/nginx/conf.d/web2py/gzip.conf;
        ### end gzip section
        ### remove the comments if you use uploads (max 10 MB)
        #client_max_body_size 10m;
        ###
    }
}
server {
    listen 443 default_server ssl;
    server_name     $hostname;
    ssl_certificate         /etc/nginx/ssl/web2py.crt;

        include         uwsgi_params;

    }

        # include /etc/nginx/conf.d/web2py/gzip_static.conf;
    }
    ###
}

请特别注意行和行

uwsgi_pass      unix:///tmp/web2py.socket;

我将 .socket 标记为特殊，但不记得为什么。不确定我可能在安装脚本中错过了它。

这可以解决您的问题吗？
