从一台新的ubuntu开始配置
1.添加新用户
使用命令
#adduser bobo
Adding user 'second' ...
Adding new group 'second' (1001) ...
Adding new user 'second' (1001) with group 'second' ...
Creating home directory '/home/second' ...
Copying files from '/etc/skel' ...
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
Changing the user information for second
Enter the new value, or press ENTER for the default
Full Name []:
Room Number []:
Work Phone []:
Home Phone []:
Other []:
Is the information correct? [Y/n] y
在/etc/sudoers可以看到有关sudo的配置，将bobo加入sudo组就可以执行sudo
#usermod -g sudo bobo
2.添加阿里的源
备份/etc/apt/sources.list
#cd /etc/apt
#mv sources.list sources.list.bak
新建一个sources.list，将以下内容写入新建的文件中
deb http://mirrors.aliyun.com/ubuntu/ trusty main multiverse restricted universe
deb http://mirrors.aliyun.com/ubuntu/ trusty-backports main multiverse restricted universe
deb http://mirrors.aliyun.com/ubuntu/ trusty-proposed main multiverse restricted universe
deb http://mirrors.aliyun.com/ubuntu/ trusty-security main multiverse restricted universe
deb http://mirrors.aliyun.com/ubuntu/ trusty-updates main multiverse restricted universe
deb-src http://mirrors.aliyun.com/ubuntu/ trusty main multiverse restricted universe
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-backports main multiverse restricted universe
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-proposed main multiverse restricted universe
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-security main multiverse restricted universe
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-updates main multiverse restricted universe
之后执行#sudo apt update即可成功更换软件源
3.安装oh my zsh
首先切换到新建的用户bobo上登录。之后$sudo apt install zsh git安装zsh和git，完成之后使用以下命令安装ohmyzsh
sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"
之后修改/etc/passwd对应账户之后的内容就可以将默认shell更改为zsh
4.安装python3.6, virtualenv,建立独立环境
安装zlib依赖
apt-get install zlib1g-dev
安装python36
wget https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tar.xz
xz -d Python-3.6.0.tar.xz
tar -xvf Python-3.6.0.tar
cd Python-3.6.0
./configure
make
sudo make install
第一次编译安装之后，有可能会发现输入python3.6 之后，方向键失效。
原因是 readline 库没有安装。
解决方式：
安装 readline 库
$sudo apt-get install libreadline-dev
安装之后，再将 python 重新编译安装一次
cd Python-3.6.0
./configure
make
sudo make install
指定环境的python版本(3.6没有zlib，很瓜皮，不好用)
virtualenv python36 --python=python3.5
