安裝

[root@node1 docker_nginx]# chmod +x /usr/local/bin/docker-compose
[root@node1 docker_nginx]# which docker-compose
/usr/local/bin/docker-compose
[root@node1 docker_nginx]# docker-compose up -d
-bash: /usr/bin/docker-compose: No such file or directory
安裝很簡單，啟動docker-compose提示找不到文件和目錄，原因很奇怪，后面再考慮，先做各軟鏈接指向/usr/bin/docker-compose解決問題再說
[root@node1 composetest]# echo 'ln -sf /usr/local/bin/docker-compose /usr/bin/docker-compose' >> ~/.bashrc
[root@node1 docker_nginx]# source ~/.bashrc
再次啟動docker-compose，提示docker沒有啟動，好吧~
[root@node1 docker_nginx]# docker-compose up -d
