docker使用自定义镜像zabbix服务

一、关闭firewall，永久关闭，使用iptables防火墙

systemctl stop firewalld.service #停止firewall
systemctl disable firewalld.service #禁止firewall开机启动
firewall-cmd --state #查看默认防火墙状态（关闭后显示notrunning，开启后显示running）

yum install iptables-services -y　　  # 安装防火墙
systemctl restart iptables.service　　# 重启防火墙

二、安装docker

要求centos7版本
yum install docker -y      安装
docker -v    查看版本
　　Docker version 1.12.6, build 3e8e77d/1.12.6
systemctl start docker 　　启动docker
ps -ef|grep docker　　　　　查看是否有docker进程
systemctl enable docker 　 设置docker开机自启动

三、下载打包好镜像文件

1）本地镜像制作过程

[root@localhost ~]# docker ps
