安装docker-compose

安装部署docker-compose（Linux环境）

参考官方文档

环境：Ubuntu 14.04 (LTS)

1、下载最新版本的docker-compose

root@ubuntu:~# sudo curl -L https://github.com/docker/compose/releases/download/1.21.2/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0
curl: (35) Unknown SSL protocol error in connection to github.com:443 
root@ubuntu:~# sudo curl -L https://github.com/docker/compose/releases/download/1.21.2/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   617    0   617    0     0    389      0 --:--:--  0:00:01 --:--:--   389
100 10.3M  100 10.3M    0     0   291k      0  0:00:36  0:00:36 --:--:--  355k

2、对二进制文件应设置可执行权限

root@ubuntu:~# sudo chmod +x /usr/local/bin/docker-compose

3、可选，bash和zsh shell安装命令完成。
4、验证安装结果

root@ubuntu:~# docker-compose --version
docker-compose version 1.21.2, build a133471
