I’ve been using the public Google DNS servers 184.108.40.206 and 220.127.116.11 for several years now. It was once said that using these DNS servers would result in a noticeable speed increase when compared with the DNS servers that your internet provider makes you use. I started using the Google servers and the addresses immediately got stuck in my head, so I haven’t stopped using them since. Until today that is…
I’ve always really liked the easy-to-remember, and simply awesome addresses 18.104.22.168 and 22.214.171.124. I was happy with the response times and I never had any issues or complaints either. So why change? I’d better have a damn good reason for making this choice! Well, obviously I do!
Yesterday somebody told me that he switched to 126.96.36.199 as primary DNS server and 188.8.131.52 as secondary. He also mentioned that the response times are fast af! That info immediately drew my attention. So I decided to further investigate this as soon as I would get home. Turns out that these servers are indeed fast and have good testing results. I also learned that the good people at CloudFlare are behind it (Wiki). I’m pretty sure that remembering these new server addresses will not be a problem either.
I’m looking for speed when it comes to DNS servers. I want to use the fastest DNS servers in existence. The more speed, the better. Naturally I also want them to be reliable, safe, and respecting my privacy. It turns out that 184.108.40.206 & 220.127.116.11 are all these things and more. So I will be saying my goodbye’s to 18.104.22.168 & 22.214.171.124. And at the same time I will be welcoming 126.96.36.199 & 188.8.131.52 with open arms. Would you like to learn more? Or do you need a step-by-step guide on how to change what DNS servers you use? Just visit the website.
I have Ubuntu16.04 servers running and I want to run database engines like MariaDB on it. Normally I would just type sudo apt install mariadb-server and the database system would be up and running in under two minutes. Ubuntu16.04 will install version 10.0 by default, but I want to install a different version. At the very least 10.1. Why 10.1 you might ask? Well because 10.1 was the first release that had Galera included by default in the package. Galera is a gift from the gods for all system administrators, developers, backup operators and other people who work with databases a lot. With three nodes, the minimum, it will offer you fast and reliable database synchronization and redundancy. Galera is a solid foundation for an easy to build load balancing environment. But first of we will install the MariaDB 10.1 instance on a clean Ubuntu16.04 server. If you want to be absolutely certain that the instructions below will work flawlessly for you, I would advise to use a clean fresh installed server also. Please remember that upgrading (or downgrading) from a different release version is NOT a good idea. When I was learning this the hard way I did a lot of reading on the subject and I can safely say that you should not follow these instructions on a system that runs, or used to run a MariaDB or MySQL instance. Even if you have removed it first apt remove you are still at risk of running into problems. When I was having problems with this I tried many things that included killing the process: kill -9 $(pgrep mysql) and then purging the removed packages apt purge and also apt autoremove and I even had to delete some left-over files manually. Don’t even try to install it on a system that ran a higher version > 10.1 because that will be guaranteed imminent failure. You’ve been warned! Let’s get started and install some required software and updates.
sudo apt update && sudo apt upgrade
sudo apt-get install nano ssh openssh-server software-properties-common rsync
