sudo apt-get install debhelper m4 autotools-dev libssl-dev libmhash-dev libmcrypt-dev 
libgdbm-dev libpq-dev libncurses5-dev libx11-dev libxt-dev libdb-dev 
libltdl-dev

Docker

on debian, follow the instruction on the official website.

And there is a domestic mirror for docker resources ：curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://51c782a9.m.daocloud.io

A typical configuration file of docker

 # setting base image
FROM debian

 # new a directory for sshd to run
RUN mkdir -p /var/run/sshd

 # installing ssh server
RUN apt-get update
RUN apt-get install -y openssh-server

 # installing sudo
RUN apt-get install -y sudo

 # make ssh services use IPv4 to let X11 forwarding work correctly
RUN echo AddressFamily inet >> /etc/ssh/sshd_config

 # defining user account imformation
ARG username=ics
ARG userpasswd=ics

 # adding user
RUN useradd -ms /bin/bash $username && (echo $username:$userpasswd | chpasswd)

 # adding user to sudo group
RUN adduser $username sudo

 # setting running application
CMD /usr/sbin/sshd -D

Then, to trigger this configuration, type

docker build -t ics-image .
docker images

# create a vm using certain image
docker create --name=ics-vm -p 20022:22 ics-image
docker start ics-vm
ssh -p 20022 ics@127.0.0.1
# see the configuration file (Dockerfile), it specifies the username and passwd of the super user of the image
exit
docker stop ics-vm

notice, you have to run these commands under root.

User Manage

Add user

groupadd rt
useradd -g rt -d /home/hzf -s /bin/bash -m hzf

# add sudo privilege

su
vi /etc/sudoers
# add 'hzf (ALL)... like the line that describes root'

 Short Cuts

  • ctrl-w delete a word before
  • ctrl-u delete the whole line
  • ctrl-r redo
