Tutorials for configuring Nginx+python environments on Linux systems via UWSGI

1. Install Ubuntu with Uwsgi PPA:

2. Replace Mod_wsgi with Uwsgi

Nginx's overall configuration here does not say, assuming already understand Nginx basic configuration, then UWSGI is similar to this configuration:

  Location/{    include uwsgi_params    uwsgi_pass 127.0.0.1:9090   

Another example is Django:

.......  From Django.core.handlers.wsgi import Wsgihandler  

Then run Uwsgi listening 9090, where-W followed by the module name, which is the MyApp just configured

Running Web site discovery has been deployed.

Parameters of 3.uwsgi

These are the simplest deployments of a single project, and Uwsgi still has a lot of admirable features, such as:

Concurrent 4 Threads:

Master control thread + 4 threads:

Perform a direct abort of the client for more than 30 seconds:

Limit Memory space 128M:

Service more than 10,000 req automatic respawn:

Background run, etc.:

4. Configure multiple sites for UWSGI

In order for multiple sites to share a UWSGI service, the UWSGI must be run as a virtual site: Remove the "-w MyApp" plus "–vhost":

Then you must configure VIRTUALENV,VIRTUALENV to be a useful virtual environment tool for Python to install:

Then set up one or more app baseline environments:

Application environment, the software installed in this environment is only valid in this environment:

Source/var/www/myenv/bin/activate  pip install Django  pip install Mako  

Last configuration Nginx, note that each site must occupy a single server, the same server different location directed to different applications do not know why always fail, estimation is a bug.

    server {      listen    ;      server_name app1.mydomain.com;      Location/{          include uwsgi_params;          Uwsgi_pass 127.0.0.1:9090;          Uwsgi_param uwsgi_pyhome/var/www/myenv;          Uwsgi_param Uwsgi_script MyApp1;          Uwsgi_param uwsgi_chdir/var/www/myappdir1;      }    }    server {      listen    ;      server_name app2.mydomain.com;      Location/{          include uwsgi_params;          Uwsgi_pass 127.0.0.1:9090;          Uwsgi_param uwsgi_pyhome/var/www/myenv;          Uwsgi_param Uwsgi_script myapp2;          Uwsgi_param Uwsgi_chdir/var/www/myappdir2;      }    

In this way, to restart the Nginx service, two sites can share a UWSGI service.
