The load balancer option is available in DigitalOcean panel under Networking. This help us create a load balancing with ease.
At Bobcares, we often get requests regarding port forwarding as a part of our Server Management Services.
Today, let’s see how our Support Engineers help our customer setup load balancer port forwarding in DigitalOcean
Load Balancing and port forwarding
Load balancing helps us distribute network traffic to multiple servers.
Again, using a Load balancer, if a single server goes down, the traffic is redirected to the remaining server.
The port forwarding helps us forward a specific port to another port or network.
Let us discuss how our Support Engineers set up port forwarding for our customers.
How we set up load balancer port forwarding
Recently one of the customers contacted us with the to configure Apache in port 8080 and set up a load balancing for his servers. Let us discuss how our Support Engineers helped our customers out.
First, we set up the Port forwarding for the Apache webserver.
Then we logged into his 2 Droplets, and we opened the file /etc/apache2/ports.conf.
We changed the listening port to 8080 on both the servers.
Then we edited the details for the domain in sites-enabled.
We changed the Virtualhost port to 8080.
Also, we need to open the port 8080 on the server. Thus, our Support Engineers used the command
iptables -A INPUT -p tcp --dport 8080 -j ACCEPT
Then we restarted the Apache service using the command
service apache2 restart
Then we logged in to the DigitalOcean control panel to set up forwarding rules. The exact steps are:
In the left pane, click on Networking.
Then click on Load Balancers tab in the networking.
We click on Create Load Balancer. Then in Choose a datacenter region we select the region.
In Forwarding rules, we add the rule.
Then in Load Balancer, we select the Protocol and it’s Port. Then in Droplet, we select the Protocol and the port we are forwarding to.
In Advanced settings, we fill in the required details. And in Health checks we change the port.
Then in Finalize and create we choose a name for the Load balancer. Finally, we click on Create Load Balancer.
And we select the Droplets for Load balancing.
That’s it. We now have a Load Balancer with port forwarding option.
