ArvanCloud Real Visitor IP

logo

This project aims to modify your Nginx configuration to let you get the actual IP address of your visitors for your web applications that are behind of ArvanCloud’s reverse proxy network. You can schedule this bash script to create an automated up-to-date ArvanCloud IP list file.

To provide the client (visitor) IP address for every request to the origin, ArvanCloud adds the “ar-real-ip” header. We will catch the header and get the actual IP address of the visitor.

  1. Create a bash script file in your desired location:

    sudo nano /var/arvancloud-sync-ips-for-nginx.sh

  2. Copy arvancloud-sync-ips-for-nginx.sh's content and save the file.

  3. Set the proper permission for the file so it can be executed:

    sudo chmod 775 /var/arvancloud-sync-ips-for-nginx.sh

  4. Now you can run the script manually to create the Nginx config file:

    sudo /var/arvancloud-sync-ips-for-nginx.sh

  5. Or schedule a new cronjob to do it automatically at regular intervals (e.g: every day at 2:30 a.m.)

    sudo crontab -e

# Auto sync IP addresses of ArvanCloud and reload the Nginx
30 2 * * * /var/arvancloud-sync-ips-for-nginx.sh >/dev/null 2>&1

Output

Now if you check /etc/nginx/conf.d directory you should see a new file named arvancloud-set-real-ip.conf which will be included in your Nginx configs automatically and sets the actual IP address for upcoming requests.

The output should be like the below:

#ArvanCloud
