1.docker安装和启动

wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -O /etc/yum.repos.d/docker-ce.repo
yum install docker-ce nginx -y
systemctl start docker

systemctl enable docker
systemctl status docker

2.配置镜像加速器

针对Docker客户端版本大于 1.10.0 的用户
您可以通过修改daemon配置文件/etc/docker/daemon.json来使用加速器

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://780urbjd.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

3.下载镜像和启动容器

docker run --name nginx -p 80:80 -d nginx

docker run --name tomcat-1 -p 8081:8080 -d tomcat  

docker run -p 81:80 --name httpd -d httpd
