freeshell@ustc之安家落户

apt-get install sudo有免费的服务器，本着不用白不用的思想，本人准备安家落户freeshell。

我科的freeshell可自选发行版，我用了默认的Debian。Freeshell里面神马都没有，只有一个root账户，SSH登陆进去的样子是这样滴：

login as: root
root@galaxy.6.freeshell.ustc.edu.cn's password:
Linux galaxy 2.6.32-openvz-042stab085.20-amd64 #1 SMP Fri Mar 21 18:52:09 MSK 2014 x86_64

freeshell里确实神马都没有，连home都没有。所以创建用户要这样：

cd /
mkdir home
useradd -D -s /bin/bash # freeshell's default value is /bin/sh
useradd -m orz # i like this name :)
passwd orz
usermod -G sudo orz # add orz into sudo group

不过这时候系统里还没有安装sudo，所以……

apt-get install sudo

这样退出之后重新登录即可使用sudo，安装些软件包之后freeshell基本能用了:)

login as: orz
orz@galaxy.6.freeshell.ustc.edu.cn's password:
Linux galaxy 2.6.32-openvz-042stab085.20-amd64 #1 SMP Fri Mar 21 18:52:09 MSK 2014 x86_64

orz@galaxy:~$

成功啦！
