HyDEV Server Setup

Notes about how to setup a Fedora 32 server for HyDEV

1. Wifi Connection for Potato Laptop Servers

Connect to ethernet first, and then:

nmcli
nmcli d connect <device>

Setting up wifi: (If wpa_supplicant isn't installed, it would say "unavailable")

dnf install NetworkManager-tui wpa_supplicant
systemctl enable wpa_supplicant
reboot

And then select the wifi and connect:

nmtui

If you are using 811AC usb wifi adapter too, install the driver:

dnf install make automake gcc gcc-c++ kernel-devel dkms
mkdir drivers
cd drivers
git clone https://github.com/brektrou/rtl8821CU
cd rt18821CU
./dkms-install.sh

Toggle USB wifi adapter mode: (Find the coresponding device ID eg. 0bda:c811)

lsusb
sudo usb_modeswitch -KW -v 0bda -p c811
reboot
nmtui

dnf install mariadb mariadb-server
sctl enable mariadb
sctl start mariadb
