I will assume the use of a Debian/Ubuntu based distro for this guide but it should be easily adaptable for CentOS. For a more recent guide, you can look at this article or the Pi-hole documentation. This article is a few years old so you will probably want to use a more recent OS such as Ubuntu 20.04LTS but the installation process is more or less unchanged.

I will not cover how to set up a Pi-hole server as I have described it previously. Note that this will restart the DNS resolver.

#Sh pull update#

You can update an existing instance to the latest version by running sudo pihole updatePihole. You will need 2 Pi-hole servers, ideally updated to the latest version but anything greater than 5.0 should work. For the greatest reliability, you will want to configure both stages.

If you are unconcerned about DNS timeouts, you can skip the IP failover setup and just have 2 servers on their own IP addresses. We then need a mechanism to monitor the servers and hand over the IP address if the primary fails. Firstly, we need a way to keep the blocklists and settings in sync between the 2 Pi-hole servers. To accomplish our goal we need to solve 2 problems. This article is therefore an updated version of that basic idea to remain compatible with the latest Pi-hole versions. However, this approach doesn’t quite work on Pi-hole 5 and above as the way the data is saved changed. The original idea for this came from u/Panja0 on Reddit.

We can resolve these problems by linking our pair of Pi-hole servers into a unified failover cluster. Using failover to provide a highly available Pi-hole cluster This can cause performance drops when one of the servers is offline. We also can’t guarantee which server clients will connect to, so if one is down, clients may still try to connect and then have to wait for a timeout before querying the second server. If we update the block lists on one, we have to remember to update them on the other.

The main problem is that we have no setting synchronisation between our servers. However, this approach has a couple of disadvantages. The simplest way to regain this redundancy is just to run 2 independent Pi-hole servers and set them as the primary and fallback DNS servers. When we set up a single Pi-hole server with no failover we lose this redundancy, meaning that if our Pi-hole ever goes down or we want to restart it for updates, we lose DNS until it is back. For example, we may assign 8.8.8.8 as a primary an 8.8.4.4 as a secondary so in the unlikely event that one is ever down, we have a second one to fall back on. Compression = 600 lbs., Our tools are not lifting / load bearing tools, SWL cert not required.Traditionally when we assign DNS servers to hosts we assign more than one. Ratings: Load testing: Static Pull = 400 lbs. The SHT 2 is available in 42-50-72” lengths. That’s why we say, Stiffy Tools-Safe Hands-Save Hands If someone breaks a Stiffy Hand Tool using it properly, that usually means a potential injury was prevented. The Stiffy Hand Safety Tool gives operators a way to mitigate risk by equipping and training workers to not place themselves in danger by working in an unsafe proximity to hazardous suspended loads. When used effectively and as designed, the Stiffy Hand Safety Tool provides a buffer zone of safety where personnel can guide, maneuver, and spot suspended loads while avoiding pinch and crush points. The Stiffy Hand Tool is crucial to the implementation of hands-free and hands-off policies. Our goal is to manufacture a line of safe hand tool to provide HSE Managers and Rigging and Slinging Trainers real solutions to create safer working conditions. This increases the tools strength significantly Each SHT 2 is enhanced with a Carbon Fiber sleeve on the neck where the tooling head is mounted.
