RHEL 7 for Seasoned Sysadmins

RHEL 7 introduces quite a few changes to how basic things on the system work. This is my scratchpad of how to do things in the new OS.

#A small guide to compile openFrameworks armv7 with driver OpenGL ES / ES2 sunxi for H3 / Mali GPU on ARMBIAN OS, compatible with orangepi and bananapi.

tested on: orangepi one banana pi M2

Deployment Architecture

System Configuration

All kubernetes nodes: set SELINUX to permissive mode

$ vi /etc/selinux/config
SELINUX=permissive

$ setenforce 0

True Color (24-bit) and italics with alacritty + tmux + vim (neovim)

This should make True Color (24-bit) and italics work in your tmux session and vim/neovim when using Alacritty (and should be compatible with any other terminal emulator, including Kitty).

Testing colors

Running this script should look the same in tmux as without.
