I just installed RS on Ubuntu server 20.04 and follow https://www.mono-project.com/docs/web/fastcgi/nginx/ without any success, repeatedly errors in table view. I want to run RS purely with Nginx without Apache. A tested working solution:
1. Add ScadaWeb to Mono XSP server:
sudo mono-xsp4-admin add --path=/opt/scada/ScadaWeb --app=/scada
2. Fix mono-xsp service bug:
sudo nano /etc/init.d/mono-xsp
change:
for i in $(ps aux | grep -v grep | grep 'xsp4.exe' | cut -c 10-15)
to:
for i in $(ps aux | grep -v grep | grep 'xsp4.exe' | cut -c 10-17)
3. Reload mono-xsp service:
sudo systemctl daemon-reload
4. Start Mono XSP server. Server will run on port 8084, you can change it in /etc/default/mono-xsp4:
sudo systemctl start mono-xsp
5. Follow https://www.digitalocean.com/community/tutorials/how-to-install-nginx-on-ubuntu-20-04 to install Nginx
6. Follow https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-20-04 to secure Nginx
7. Edit /etc/nginx/sites-available/example.com and add:if ($scheme != "https") { return 301 https://$host$request_uri; } location /scada { proxy_pass http://127.0.0.1:8084; sub_filter 'example.com:8084' 'example.com'; sub_filter 'example.com%3a8084' 'example.com'; sub_filter_once on; proxy_redirect off; proxy_buffering off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; }8. Restart Nginx:
sudo systemctl restart nginx
9. Test as previous post.NOTE: Not tested to load a scheme yet but “Unable to receive list of plugins” in Main Menu – Plugins – Download
I set InHand 615’s serial port as TCP client on port 40000, RS as Modbus master on TCP server communication line. After that I can access Schneider PM810MG via cellular network but the problem I got communication error repeatedly and sometime RS still assume incorect response as a correct value, data value
jumping strangely. My solution for now make use of Perle TruePort driver for Linux https://www.perle.com/downloads/trueport.shtml as TCP server on port 40000 and RS access serial data from /dev/tx0000. Working good so far.Perle TruePort config in /etc/trueport/config.tp:
/usr/bin/trueportd -noudp -opmode optimize_lan -tty 0 -port 40000 -ka 30Perle TruePort driver also available for Windows with better configuration GUI.
Yes, 5.8.2 Mono installed on Raspberry Pi 4B, Ubuntu server. I’m afraid it’s also related to browser/server cache.
Just received InHand 4G modem from their local distributor for testing. Not as good as Moxa device but cheaper.
For a brand new installation, I create ULR link entry under HelloWorld\Simulator.tbl in Interface table. For example: Path: https://www.myhome.com, Title: HelloWorld\Home. It’s work after initial upload, click on Home link will open https://www.myhome.com . But later even after I have change Home link to https://www.myhome.com/subpage, I always got https://www.myhome.com
I’ll try it @Mikhail. For now I accessed it from Node-RED using node-red-contrib-modbus. I have to enable TCP in telnet mode because got incorrect Modbus stream in default TCP mode.
My English not good enough to explain but I can upload RS project from Windows to Linux over internet easily.
@Mikhail Today I realized how simple NPort in TCP mode. Thank you.
Not actually NPort device I use here but a GSM modem from Moxa with a serial port. With a private IP from GSM operator, the only option to access it is via OnCell Central Manager. OCM map the serial port to a local TCP port.
At least we have 2 options to run RS with SSL even with a negative impact if exists. Nginx + Mono FastCGI will be perfect for RS but I have multiple application run under Apache for now.
Run Mono FastCGI via Nginx behind Apache (even Apache behind Nginx must be better):
1. Install Nginx:
sudo apt-get install nginx
2. Change Nginx default port from 80 to 8008 and add /scada-fastcgi virtual path:
sudo nano /etc/nginx/sites-available/default
listen 8008 default_server; listen [::]:8008 default_server;location /scada-fastcgi { index index.html index.htm default.aspx Default.aspx; fastcgi_index index.htm; fastcgi_pass 127.0.0.1:9000; include /etc/nginx/fastcgi_params; }3. Edit Nginx FastCGI parameter:
sudo nano /etc/nginx/fastcgi_params
fastcgi_param PATH_INFO ""; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;4. Edit Apache config and reload it:
sudo nano /etc/apache2/sites-enabled/default-ssl.conf
ProxyPass /scada-fastcgi http://127.0.0.1:8008/scada-fastcgi ProxyPassReverse /scada-fastcgi http://127.0.0.1:8008/scada-fastcgisudo systemctl reload apache2
5. Install Mono FastCGI if needed, run it:
sudo apt-get install mono-fastcgi-server
fastcgi-mono-server4 /applications=/scada-fastcgi:/var/www/html/scada/ /socket=tcp:127.0.0.1:90006. Start Nginx:
sudo systemctl reload nginx
You can access SCADA web at https://yourserver/scada-fastcgi
No problem here, I can access for example http://scada.myserver.com/ without a redirect. But to be honest, I’m not expert in Apache configuration.
I think run scada web as web root for my server is not a good idea since I also use it for different service.
1. Edit scada-xsp4 config:
sudo nano /etc/xsp4/scada.webapp
<apps> <web-application> <name>scada</name> <vpath>/scada</vpath> <path>/opt/scada/ScadaWeb</path> </web-application> </apps>2. Edit Apache config:
sudo nano /etc/apache2/sites-enabled/default-ssl.conf
SSLProxyEngine on SSLProxyVerify none SSLProxyCheckPeerCN off SSLProxyCheckPeerName off SSLProxyCheckPeerExpire off ProxyPreserveHost off ProxyRequests off ProxyVia off ProxyPass /scada http://127.0.0.1:8000/scada ProxyPassReverse /scada http://127.0.0.1:8000/scada3. Disable scada web in Apache:
sudo a2dissite scada.conf
4. Restart scada-xsp4 service:
sudo service scada-xsp4 stop
ps ax –> to check mono pid that load xsp4.exe
sudo kill -9 pid_from_previous_step
sudo service scada-xsp4 start5. Restart Apache:
sudo service apache2 restart
I can’t edit my previous post, you can test previous configuration by accessing for example https://scada.rapidscada.org/ after restarting Apache web server:
sudo service apache2 restart
For my future references:
1. Run Apache and Nginx together: http://kbeezie.com/apache-with-nginx/
2. Mono and Nginx: https://www.mono-project.com/docs/web/fastcgi/nginx/PART 2: Apache configuration
Depend on your server configuration, my working /etc/apache2/sites-enabled/default-ssl.conf configuration:
SSLProxyEngine on SSLProxyVerify none SSLProxyCheckPeerCN off SSLProxyCheckPeerName off SSLProxyCheckPeerExpire off ProxyPreserveHost off ProxyRequests off ProxyVia off ProxyPass / http://127.0.0.1:8000/ ProxyPassReverse / http://127.0.0.1:8000/
