前提：已经安装完docker
直接执行下列命令：
1.拉取文件
[root@localhost ferry]# curl -L "https://github.com/docker/compose/releases/download/1.25.5/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compos
2.赋予权限
[root@localhost ferry]# chmod +x /usr/local/bin/docker-compose
3.查看版本
[root@localhost ferry]# docker-compose -v docker-compose version 1.25.5, build 8a1c60f6
