Linux barebones quickstart
Install the distro
Set up IP
DO THIS NOW, NEVER LET A CLONE USE THE SAME IP, you will tear your clothes and spit on the ground! The only time to skip is if you are using DHCP.
# on home lan, dnsmasq doles out the ips based on MAC, make sure you have it configured # for static IPs on ubuntu work machines: sudo emacs /etc/network/interfaces # for static IPs on centos work machines: sudo emacs /etc/sysconfig/network-scripts/ifcfg-ens192 service network restart # example: BOOTPROTO=none IPADDR=10.122.82.241 NETMASK=255.255.255.0 GATEWAY=10.122.82.1 # For VMs, change network adapter if needed to match subnet (eg "LabNet8X") # for virtualbox no changes were needed (as of yet)
Set up DNS
You should probably turn off systemd-resolved.
Set up hostname
Note that this is not needed for a fresh install of ubuntu. But if you've cloned a VM, you'll need to change hostname:
sudo emacs /etc/hostname && sudo hostname newname # use hostname cmd to set it right away # NOTE that systemd can also be used: sudo hostnamectl set-hostname newname # /etc/hosts changes should not be needed, if hostnames are properly configured (dnsmasq DNS -or- work DNS will provide resolution)
Install basic tools
sudo apt install git curl emacs # ubuntu sudo yum install git curl emacs # centos git config --global user.email firstname.lastname@example.org git config --global user.name "Michael Behrns-Miller [##hostname##]"
Set up scripts
cd && mkdir development && cd development git clone bitpost.com:development/scripts.git ./scripts/setup_linux.sh # to continue bootstrapping
That's it, get on with your life.
MIGRATION IN PROGRESS: config distro machine migration
Start to revamp config from [machine]/[distro] to [distro]/[machine] to match scripts. It's not hard even though it's dangerous. You can do each machine separately from others. Get on it!
# DO THIS ALL IN ONE SESSION, do not log out cd development/config mkdir -p distro # prolly not needed git mv machine/distro distro/machine setup_stow.sh # repeat until it doesn't fail; check each failure to make sure it is a symlink, and simply rm them as you go
moving all this to setup_linux.sh and mh-setup-linux command...
cd && ln -s development/scripts scripts mkdir scripts/[distro]/[new machine] emacs -nw .bashrc # export PATH=$HOME/scripts/[distro]/[machine]:$HOME/development/scripts/[distro]/i3:$HOME/development/scripts/[distro]:$PATH
Set up ssh
# openssh-server defaults are ok but see /etc/ssh/sshd_config for details cd ~/.ssh scp [another-working-setup]:.ssh/authorized_keys . scp [another-working-setup]:.ssh/id_rsa_3072_nopswd . scp [another-working-setup]:.ssh/config . ln -s id_rsa_3072_nopswd id_rsa # also add any other private keys and run [chmod 400] on them
Set up config
cd ~/development git clone bitpost.com:development/config.git cd config mkdir -p [distro] && cd distro cp -rp [existing machine] [new machine] # EDIT IT ALL # WARNING - EDIT ACTUAL SYSTEM FILES, NOT repo files, as those will get clobbered when you stow # BACK EVERYTHING UP AS YOU GO until we get really good at this :-) git add [new machine] git commit -a -m "new machine" && git push cd && ln -s /home/m/development/config/ optional:[gig]/ [distro]/[new machine] config
