Ubuntu 20.04 LAMP setup

Note: Because this is my personal cheat sheet, I'm installing a few PHP modules that you may not need if you're not running SilverStripe 4.x.x. Otherwise this is a pretty standard and secure LAMP installation.

SECURITY FIRST: Add a sudo user, require public key authentication and disable root login

Log into the remote machine as root: ssh root@123.45.67.890

First, add the admin user.

Generating RSA keys

On a Mac or other Unix-like system, locate your ~/.ssh directory and from that directory run this in the command line:

ssh-keygen -t rsa -b 4096 -C "your_comment"

-t = type (The possible values are 'dsa', 'ecdsa', 'ed25519', or 'rsa')

-b = bits

Creating TAR backups

Bash example

• First create a timestamp that looks something like (YearMonthDay-Hour:Minute:Second) or (20200512-02:30:00). This will give you a unique identifier.
• Then cd into the directory you want to back up.
• Create a tar.bz2 (bzip2 compression) file.
• Optionally, delet the original files.

Example:

wpa_supplicant.conf

country=US
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
    ssid="your_real_wifi_ssid"
 scan_ssid=1
