docker和docker-compose安装

1、添加DNS配置
vi /etc/sysconfig/network-scripts/ifcfg-bond0
DNS1=218.85.157.99
service network restart
2、安装docker
安装依赖包和docker源
yum install -y yum-utils
device-mapper-persistent-data
lvm2

yum-config-manager
–add-repo
https://download.docker.com/linux/centos/docker-ce.repo
安装docker
yum install docker-ce
启动服务：systemctl start docker
设置docker下载镜像地址：vi /etc/docker/daemon.json
{
“registry-mirrors”: [“https://registry.docker-cn.com”]
}
systemctl restart docker.service
3、安装docker-compose
curl -L https://github.com/docker/compose/releases/download/1.3.3/docker-compose-uname -s-uname -m > /usr/local/bin/docker-compose（可以使用wget下载，会比较快）
chmod +x /usr/local/bin/docker-compose
检测docker-compose安装成功与否：
docker-compose -v
