安装前的准备工作
1、更新内核和软件包
yum -y update
2、关闭防火墙和selinux，开启iptables
systemctl stop firewalld;systemctl disable firewalld;sed -i 's/^SELINUX=enforcing$/SELINUX=disabled/' /etc/selinux/config;setenforce 0;yum -y install iptables-services;systemctl start iptables ;systemctl enable iptables;iptables -F;iptables -X;iptables -Z;service iptables save
3、重启使用新的内核(默认)
reboot

安装docker-ce
1、安装依赖
yum install -y yum-utils device-mapper-persistent-data lvm2 vim
2、配置aliyun的docker源
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
3、安装docker-ce
yum list docker-ce --show-duplicates
yum -y install docker-ce-18.09.9
4、启动
systemctl start docker;systemctl enable docker
5、修改内核相关参数
~]# vim /etc/sysctl.conf
net.ipv4.ip_forward = 1
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-ip6tables = 1
~]# sysctl -p
6、测试
systemctl restart docker
docker info
docker run hello-world

配置docker镜像加速器
1、去aliyun复制
2、mkdir -p /etc/docker && vim /etc/docker/daemon.json
{
  "graph": "/data/docker",
  "storage-driver": "overlay2",
  "bip": "172.17.0.1/16",
  "exec-opts": ["native.cgroupdriver=systemd"],
  "registry-mirrors": ["https://aovsavxe.mirror.aliyuncs.com"],
  "insecure-registries": ["hub.boya.com"],
  "live-restore": true
}
3、重启
systemctl daemon-reload && systemctl restart docker
