console log in as root, no password.
setup-alpine, answer ALL questions.

source /root/.profile to make the profile effective without re-login.
apk update

install these needed.

apk add curl nano nano-syntax rsync nginx samba tree file bc iproute2

configure nano syntax highlight

nano -w ~/.nanorc
include /usr/share/nano/*.nanorc

enable bash shell, Alpine default shell is Busybox.

apk add bash
# you can EASILY switch busybox/ash shell to bash shell by modify the /bin/sh link
ll /bin/sh
/bin/sh -> /bin/busybox
rm /bin/sh
ln -s /bin/bash /bin/sh
ll /bin/sh
/bin/sh -> /bin/bash
# relog in, and you will see .bash_history is replaced .ash_history

add ssh id

cd;mkdir .ssh;cd $_ && nn authorized_keys

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDKA+yUNpBGeIJzYKsS3BTjs6M4RIc9bDk2D1Z2lOhmWKciEMf6gi8LQmBIjB6Bf5J9m3Fg1uJE/oNt2MTYjKP4asRcKud1rEkNFf87CsJMX2faTLE3Tnfz/Q8lDGQPkZ2eE5CuAbjP3aUcbPx7tanMh+qe5oTXnL6dmqtcl8jMgCrr8wH6RTLR+KO5yGSuDRAOx7RM4Vz1IbrLUCxicGkDn+dmjbdMOl0HUZbtg4iuGAEsdB94JxTrD+z7IN+95j5FuWfP7ykcKfZQIPC1R7ktwTLI+yRwpOkQAHeqRI1va+AWqz3y645sOfxI+UcH/TwF7cw4dr/octtyN4ISI4F5 root@s08
