1. Find the nginx configuration file nginx.conf
1. View the actual call configuration file of Nginx
ps aux|grep nginx
root 352 0.0 0.0 2468624 924 ?? S 10:43上午 0:00.08 nginx: worker process
root 232 0.0 0.0 2459408 532 ?? S 10:43上午 0:00.02 nginx: master process /usr/sbin/nginx -g daemon on;
root 2345 0.0 0.0 2432772 640 s000 S+ 1:01下午 0:00.00 grep nginx
It can be seen that the Nginx path is /usr/sbin/nginx
2. Check the Nginx configuration file path
Use the -t parameter of Nginx to check the configuration, and you can know the path of the configuration file actually called and whether the call is valid.
/usr/sbin/nginx -t
nginx: the configuration file etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
2. Enter the nginx.conf file, find the directory path containing conf.d and configure it
can be seen:
include /etc/nginx/conf.d/*.conf;
Move the configuration file downloaded in the Pyscada document into the /etc/nginx/conf.d directory: (you can also move it while downloading)
cd /etc/nginx/sites-enabled
mv pyscada.conf /etc/nginx/conf.d
Enter pyscada.conf to modify it
cd /etc/nginx/conf.d
nano pyscada.conf
Because there is no https certificate, and there is no need to use https, just use http, so delete the content and modify the file to the following:
# pyscada.conf
# the upstream component nginx needs to connect to
upstream app_server {
server unix:/tmp/gunicorn.sock fail_timeout=0; # for a file socket
#server 127.0.0.1:8000 fail_timeout=0; # for a file socket
}
# configuration of the server
server {
listen 8081;
listen [::]:8081;
server_name _; # substitute your machine's IP address or FQDN
#return 301 https://$server_name$request_uri;
#return 301 https://$host$request_uri;
# Django media
location /media {
alias /var/www/pyscada/http/media; # your Django project's media files - amend as required
}
location /static {
alias /var/www/pyscada/http/static; # your Django project's static files - amend as required
}
location /measurement {
alias /home/pyscada/measurement_data_dumps; # to support download of measurement files via admin backend - amend as required
}
location / {
# checks for static file, if not found proxy to app
try_files $uri @proxy_to_app;
}
location @proxy_to_app {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://app_server;
}
}
Here, port 8080 is already occupied by openplc, so it is changed to port 8081, and readers can modify it according to their own conditions. After modification, restart Nginx.
nginx -s reload
The pyscada configuration ends here. Perform follow-up configuration according to official documents, and finally enter the following command to open pyscada.
sudo systemctl start pyscada
Open the browser and enter localhost:8081 to enter the pyscada login interface, enter the user name and password to log in successfully.
