Docker设置代理
（1）国内很多镜像无法访问，因此需要配置代理访问外部镜像，配置方法如下：
[root@dev ~]# vi /etc/docker/daemon.json
{"iptables": false,"data-root": "/home/docker/store","registry-mirrors": ["https://docker.m.daocloud.io","https://huecker.io","https://dockerhub.timeweb.cloud","https://noohub.ru","https://ipv4.mirrors.ustc.edu.cn","https://tivt17e5.mirror.aliyuncs.com"],"proxies": {"http-proxy": "http://192.168.31.177:7890","https-proxy": "http://192.168.31.177:7890"}
}
注意增加如上两个配置和http-proxy和https-proxy
（2）安装Docker
yum -y install yum-utils device-mapper-persistent-data lvm2
yum -y install docker-ce
systemctl daemon-reload
（3）重启Docker
[root@dev ~]# systemctl restart docker
[root@dev ~]#
（4）现在可以搜索镜像了
[root@dev ~]# docker search nginx

（5）创建实例
docker run --name nginx --privileged=true --restart=always -d -p 80:80 -v /home/docker/nginx/html:/usr/share/nginx/html:ro nginx:latest# 带配置文件，注意先新建配置文件/home/docker/nginx/conf/nginx.conf
docker run --name nginx --privileged=true --restart=always -d -p 80:80 -v /home/docker/nginx/conf/nginx.conf:/etc/nginx/nginx.conf:ro -v /home/docker/nginx/html:/usr/share/nginx/html:ro nginx:latest
/home/docker/nginx/conf/nginx.conf配置文件内容如下：
#user nobody;
worker_processes 1;#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;#pid logs/nginx.pid;events {worker_connections 1024;

其它
（1）移除历史Docker
# 更新系统并清理旧版本 Docker
sudo yum update -y
sudo yum remove docker* -yyum remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-selinux docker-engine-selinux docker-engine
rm -rf /etc/systemd/system/docker.service.d
rm -rf /var/lib/docker
rm -rf /var/run/docker
（2）安装历史版本
yum install https://download.docker.com/linux/centos/7/x86_64/stable/Packages/docker-ce-18.09.9-3.el7.x86_64.rpm
（3）放开防火墙
firewall-cmd --zone=public --add-port=80/tcp --permanent && firewall-cmd --reload
