CentOS 7 install docker及docker-compose下载太慢问题解决

1.install Docker

sudo yum install -y yum-utils device-mapper-persistent-data lvm2
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
sudo yum install docker-ce
sudo systemctl enable docker.service
sudo systemctl start docker.service

2换docker-compose源下载. https://my.oschina.net/u/1440971/blog/3039640

curl -L https://get.daocloud.io/docker/compose/releases/download/1.25.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

sudo chmod +x /usr/local/bin/docker-compose
