Godaddy weirdness
This site was offline for a week or so and I couldn’t figure out what was going on. It looks like what happened was that somehow the IP address in the A record was changed to 173.212.241.155, which is somewhere in Europe, instead of the correct address listed for the basic web hosting at Godaddy. Once […]
phpmyadmin hybrid install (apt + manual) on Ubuntu
While migrating our websites to the new Ubuntu box, I set up phpmyadmin using apt-get. But that package is 4.5x while the latest version is 4.8x. Not surprisingly, the Nessus security scan needed to get http and https ports opened through the TAMU firewall detected security exploits that I hope have been fixed in the […]
Multiple Docker mysql instances on different ports
Found a tutorial gives the following example: $ docker run -d –name=new-mysql -p 6604:3306 -v /storage/docker/mysql-datadir:/var/lib/mysql mysql let’s dissect what we’re passing to docker -d is short for –detach. This runs the container as a daemon in the background –name is the name of the container -p is short for –publish. This is a port […]
Adventures in Linux hosting: Multiple MySQL instances
Reading up on mySQL, I realized that rather than using Docker or VMs, the simplest thing to do is run multiple mySQL instances from the default installation. Because the new machines are Ubuntu Linux, this can be controlled from systemd, the daemon that controls services. There is also documentation on mysql.com about using Docker and […]
Adventures in Linux hosting: Learning to use Docker
In the past, I’ve tried running multiple wikis from a single LAMP stack just using different databases for each one. The problem I ran into was that anything that caused one wiki to lock up mysql caused all of the wikis to lock up at the same time. This could happen during when some bot […]
Adventures in Linux hosting: Misc. setup with apt
After setting up the new home linux box on Xmas eve, I’ve been gradually building it up to be a test bed for things I do at work. The apt package manager makes this pretty easy so far, compared to what I’ve done in the past. emacs Sorry vim folks, I prefer emacs for shell […]
Adventures in Linux hosting: Getting Ubuntu onto my home Dell T30
Thanks to the USPS for delivering on a Sunday. The new T30 arrived today at around 10AM. As I suspected, the contents are just the main box and a power cord. I went to Best Buy and picked up the cheapest USB2 keyboard and mouse I could find (there were probably some of these lying […]
Adventures in Linux hosting: Development setup at home
One option to do my self-designed Linux education would be to do everything in VMWare. But while I’ve done that in the past, it hasn’t taught me what’s going on when we’ve had problems with our existing boxes where the IT people tell me that they had to do something with the kernel, or when […]
Time for me to get more serious about Linux
My group started into bioinformatics thanks to former students Hai Zhu and Leonardo Marino-Ramirez, who set up the first LAMP webserver in the lab, a box they made that we called tofu.tamu.edu. Being Mac users, we thought that the Unix roots of OSX would be useful in the transition to doing informatics and web-based resources, […]
