As of 7.7.2019, all servers are on Ubuntu 18.04.2 with LTS Enablement.
LTSEnablementStack is a cool page on upgrading the kernel to the latest revision for many flavors of Ubuntu. I upgraded both WordPress Ubuntu 16.04.6 servers to 4.15 kernel using the script on the LTS Enablement page.
I discuss how I screwed up and fixed chown mistakes.
I dive into 18.04 for the first time. So far 18.04.2 is working fine.
I cover MariaDB, PHP, Samba, Backup solutions for Linux/VMWare, Syslog-NG, and Webalizer.
I retired out my CentOS 7 WordPress server. Just didn’t backup as fast as Ubuntu. I used Duplicator to migrate the WordPress site over to Ubuntu. Awesome plugin.
