PowerServer 2022 R3 Help
Nginx (Linux)

This section is to configure Nginx as a reverse proxy server in a Linux machine.

Step 1: Go to the /etc/nginx/ folder and open the nginx.conf file in a text editor.

Step 2: Locate the "server" block and add another "server" block as shown below.

This is to configure Nginx as a reverse proxy server which will redirect requests made to the URL: https://172.16.100.51:8080/ to the PowerServer Web APIs running on Kestrel at https://172.16.100.35:6000/.

    server {
        listen  8080;
        location / {
           proxy_set_header Host $http_host;
           proxy_pass  https://172.16.100.35:6000;
        }
    }

Tip: In CentOS, you can execute the command "netstat -anp | grep 8080" to check if the port number is occupied by any other program.

Step 3: Run the following command to add port 8080 to "http_port_t":

$ sudo semanage port -a -t http_port_t -p tcp 8080

Step 4: If you have set up a firewall on the server, run the following command to permanently enable port 8080:

$ sudo firewall-cmd --permanent --zone=public --add-port=8080/tcp

and the following command to reload the firewall service:

$ sudo firewall-cmd --reload

Step 5: Check if any syntax errors in the Nginx configuration file, and then restart Nginx for the changes to take effect.

$ sudo nginx -t

$ sudo systemctl restart nginx

Step 6: Verify that Nginx is running.

$ sudo systemctl status nginx

Step 7: Run the following command to allow Nginx to make outbound connections.

$ sudo setsebool -P httpd_can_network_connect 1
