Part 8 of our video series on how to set an ISP-style cluster for Qmailtoaster.

We finalize all of the backend file linking to get our cluster all ready.

This week we link the last of the directories to the backend we've set up in the first few episodes. Now that the last of the directories we need are pointed at the backend, we can move to the last step next week!

Part 7 of our video series on how to set an ISP-style cluster for Qmailtoaster.

This week we begin to set up our front end machine to use the backend array that we set up in the previous videos.

Now that we have a highly available, redundant storage system for the back end, it's time to start mapping our front end machines to the back end NFS storage system. This week we map some of the config files, and explain why we do not map them all.

Part 6 of our video series on how to set an ISP-style cluster for Qmailtoaster.

In this week's video, we overview how the front end machines will be set up, and begin installation of our first public facing server.

Now that our backend systems are all set up, we take an overview on how the front end machines will be set up and begin installation of our first front end machine using the CentQMT5 ISO.

Part 5 of our video series on how to set an ISP-style cluster for Qmailtoaster.

This is the last video on setting up the backend for our mail server cluster. We're in the home stretch!

In this video, we wrap up our backend systems. At this point you should have redundant, and highly available backend storage systems to maintain the mail store and the database with resiliency. Next week we move on to the front end systems!

Part 4 of our video series on how to set an ISP-style cluster for Qmailtoaster.

We continue to set up our highly available and redundant backend in this week's video. Our main focus in this video: setting up the database to replicate between the backend servers. This way there is a copy of the database information on both servers for redundancy, and it is replicated on the fly.

Part 3 of our video series on how to set an ISP-style cluster for Qmailtoaster.

This episode continues on from the last episode on how to set up the backend for a cluster system. We add failover protection with heartbeat in this episode so that even if one of the backend servers fails, the other server will assume it's virtual IP address and continue to serve data with a minimal downtime for the frontends.

Part 2 of our video series on how to set an ISP-style cluster for Qmailtoaster.

In this episode, we start to set up our backend filesystem. It's critical that the backend be highly available and redundant, or the redundancy on the public facing front end has a poor base to be built upon. We start off by setting up two backend servers that will replicate the data with each other, independently of the file system that the data store is actually formatted with. Since the backend is so critical to this setup, this video and the next video will focus on the backend servers.

We kick off a new video series starting this week on how to build an ISP-style Qmailtoaster cluster.

There has been a lot of success from the replication video. Quite a few users have emailed me to let me know that that video series really helped them. I expand on that idea by starting a new video series on how to set up an ISP-style Qmailtoaster cluster.
You will have multiple public-facing machines to handle massive amounts of email (both incoming and outgoing) with a common mail-store backend so that all servers share the same mail store. This is very similar to a 1-million user setup which I consulted on a couple of years back, scaled down for smaller ISPs. The design could easily be scaled up to handle that many users by dynamically adding additional servers into the array. I'll cover all of this in the upcoming weeks as we build on our ISP-style cluster and add the various components.

This week's video is a user request, and gets us back to some basics.

We tend to forget about some basics when administering our servers, so this week I go back and show you how to add domains, and administer mailing lists plus a couple other tips. I explain how to add domains using the command line, and why you should not use vqadmin at this time. I also show you how to administer domains using the existing tools, as well as the functionality of QControl.

How to manage multiple Qmailtoaster servers

I've often been asked, how do I manage multiple servers and keep all the passwords straight?

I'll admit I keep documents detailing each server that I set up an manage, but opening a document every time I want to log into a server to get a password that I probably don't remember is not very efficient. I use SSH keys to log into the servers so that I can log in securely and not have to remember passwords for every server. Watch this week's video and I'll show you how easy it is.
