How to free up port 80 for Xeams and Let's Encrypt in Synametrics VM

In the Synametrics VM product, this Virtual Machine contains 4 products:
  • Syncrify - uses port 5800 by default.
  • SynaMan - uses port 6060 by default.
  • Xeams - uses port 5272 by default.
  • Rainloop - uses port 5678 by default.
Additionally, port 80 is occupied by Nginx. Visiting this port displays the default home page, which contains links to products. This is added to easily navigate the other products. However, if you use this in production, you'll want to configure this port to a different value or not to use it. An example of this is if you want to use Let's Encrypt SSL certificate in Xeams.
To modify this, follow the steps below to either change the port or remove this homepage:

Option #1: Change the Nginx port to a different value

  • In the terminal, switch to the root user by entering the following command:
    sudo su
    You will be prompted for a password. The password is: secret010273
  • Go to the following directory by entering the command below:
    cd /etc/nginx/sites-available
  • You should see a file named default. Open this file with a text editor such as nano. Example command below:
    nano default
  • On lines 22 and 23, you should see the following:
    listen 80 default_server;
    listen [::]:80 default_server;
  • Modify the values 80 above to something else, like port 8080. It should look something like this:
    listen 8080 default_server;
    listen [::]:8080 default_server;
  • Save the file and exit. Next, run the following command to restart Nginx:
    systemctl reload nginx
You can confirm port 80 is no longer in use by entering the following command: nginx -T | grep listen

Here's an example result below: In the screenshot above, port 80 is not in use because of the '#' character.

Option #2: Disable/Uninstall Nginx

If you do not use Rainloop and do not want the home page to be displayed at all, follow the instructions below:
  • In the terminal, switch to the root user by entering the following command:
    • sudo su
    You will be prompted for a password. The password is: secret010273
  • Stop the Nginx server by running the following command:
    sudo systemctl stop nginx
  • If you want to disable Nginx, run the following command:
    sudo systemctl disable nginx
  • To uninstall Nginx, run the following commands:
    sudo apt remove nginx
    sudo apt purge nginx nginx-common
    Note: if the apt remove nginx command is stuck, run the following command:
    systemctl stop unattended-upgrades
    then try again. Once it's uninstall, start the unattended-upgrades service again:
    • systemctl start unattended-upgrades
  • Nginx will now no longer be running.
Once you do either option above, log into Xeams as admin, then click on Server Configuration. Here, set the "2nd Web Server Port" to 80, then click on Save. It should ask you to restart Xeams. Restart, then you can continue configuring the Let's Encrypt.

Optional: Remove Syncrify and SynaMan

If you are only using the VM for Xeams and want to remove Syncrify and SynaMan, follow the instructions below:
  • In the terminal, switch to the root user by entering the following command:
    sudo su
    You will be prompted for a password. The password is: secret010273
  • Go to the installation directory of Syncrify by entering the following command:
    cd /opt/Syncrify
  • You will first need to grant executable permission for the Uninstall.sh file. To do this, please enter the following command below:
    chmod +x Uninstall.sh
  • Next, run the Uninstall.sh script by entering the following command:
    ./Uninstall.sh
    This will uninstall Syncrify.
  • Go to the installation directory of SynaMan by entering the following command:
    cd /opt/SynaMan
  • You will first need to grant executable permission for the Uninstall.sh file. To do this, please enter the following command below:
    chmod +x Uninstall.sh
  • Next, run the Uninstall.sh script by entering the following command:
    ./Uninstall.sh
    This will uninstall SynaMan.
