v2.5.1
v2.6.1
v2.7.0
v2.10.2
#设置权限
sudo chmod +x /usr/local/bin/docker-compose


下载太慢直接下载文件
sudo mv docker-compose-linux-x86_64_v2.3.4 /usr/local/bin/docker-compose
mv docker-compose-linux-x86_64 /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
改名为 /usr/local/bin/docker-compose (注docker-compose是文件名)
