1、修改163源(trusty)這個快
進入/etc/apt/目錄下，修改目錄下sources.list
命令:
cd /etc/apt/
sudo cp ./sources.list ./sources.list.ubuntu
sudo gedit ./sources.list
由於是sudo輸入密碼回車，以後有sudo的都需要。
下面是內容
deb http://mirrors.163.com/ubuntu/ trusty main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ trusty-security main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ trusty-updates main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ trusty-proposed main restricted universe multiverse
deb http://mirrors.163.com/ubuntu/ trusty-backports main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ trusty main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ trusty-security main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ trusty-updates main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ trusty-proposed main restricted universe multiverse
deb-src http://mirrors.163.com/ubuntu/ trusty-backports main restricted universe multiverse
sudo apt-get update
2、五筆輸入法
sudo apt-get install fcitx-table-all
sudo apt-get install fcitx-table-wbpy
3、瀏覽器
sudo apt-get install chromium-browser
4、加速github
設置hosts
1. 登錄http://tool.chinaz.com/dns/
2. 查詢以下域名映射,並分別取訪問速度較快的一個ip
github.global.ssl.fastly.net -> 151.101.229.194
assets-cdn.github.com -> 151.101.229.194
3. 將查詢到的ip和域名設置到host中

# update-alternatives --install /usr/bin/python python /usr/bin/python2.7 1
update-alternatives: using /usr/bin/python2.7 to provide /usr/bin/python (python) in auto mode
# update-alternatives --install /usr/bin/python python /usr/bin/python3.4 2
update-alternatives: using /usr/bin/python3.4 to provide /usr/bin/python (python) in auto mode
remove
update-alternatives --remove python /usr/bin/python2.7
切換
update-alternatives --config python #切換命令
查看
update-alternatives --list python
7、修改path,
sudo gedit ~/.bashrc
保存後重啓終端
