vim /usr/lib/sysctl.d/00-system.conf

添加如下内容:

net.ipv4.ip_forward=1

安装好docker

 sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

sudo yum install -y yum-utils
sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo
sudo yum install docker-ce docker-ce-cli containerd.io

创建一个外部的容器挂载:

mkdir /root/nginx

先开启一个容器复制出/etc/nginx下的内容
随后删除之前起的容器执行以下命令:

docker run -p 9005:80 --name nginx -v /root/nginx/html:/usr/share/html -v /root/nginx/log:/var/log/nginx/ -v /root/nginx/conf:/etc/nginx/ -d nginx:1.10```
