7.uwsgi To configure

Django After normal operation, we will start to configure uwsgi.

Our website project path is /data/wwwroot/mysite/, Create... In the project root directory
mysite.xml file , Enter the following ：

<uwsgi>
<socket>127.0.0.1:8997</socket><!-- The internal port , Customize -->
<chdir>/data/wwwroot/mysite/</chdir><!-- Project path -->
<module>mysite.wsgi</module>
<processes>4</processes> <!-- Number of processes -->
<daemonize>uwsgi.log</daemonize><!-- Log files -->
</uwsgi>

And save
In the configuration file mysite This is the name of our project .

cd /etc/nginx
Back it up nginx.conf file , In case of accident ,
cp nginx.conf nginx.conf.bak
Then open the nginx.conf, Delete the original content ,

uwsgi_param UWSGI_SCRIPT mysite.wsgi;
uwsgi_param UWSGI_CHDIR /data/wwwroot/mysite; # Project path
}
location /static/ {
alias /data/wwwroot/mysite/static/; # Static resource path
}
}
}

Execute the following command to check the configuration file for errors
nginx -t, If there is no mistake, execute the following command ：nginx
Terminal proof without any prompt nginx Successful launch . You can use your server address to view , After success, you will see a nginx The welcome page .
