一、环境设置
1.1、系统设置
OS ：Centos 8
ip和域名设定
192.168.25.75 k8s-master.zhouyihua.com
192.168.25.76 k8s-node1.zhouyihua.com
192.168.25.77 k8s-node2.zhouyihua.com
1.2、卸载podman，系统默认安装了podman容器和docker有冲突
#!/bin/bash
#zhouyihua
#v0.1
#2021-09-05
yum remove podman -y
yum erase podman buildah -y
setenforce 0
sed -i 's/^SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
#DISABLE SWAP
swapoff -a
sed -i 's/.*swap.*/#&/' /etc/fstab
systemctl stop firewalld.service
systemctl disable firewalld.service
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-8.repo
yum install -y yum-utils device-mapper-persistent-data lvm2 net-tools
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
wget https://download.docker.com/linux/centos/7/x86_64/edge/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm
yum install containerd.io-1.2.6-3.3.el7.x86_64.rpm -y
mkdir -p /etc/docker
vim /etc/docker/daemon.json << EOF
{
"registry-mirrors" : ["https://mj9kvemk.mirror.aliyuncs.com"]
}
EOF
yum -y install docker-ce
systemctl daemon-reload && systemctl start docker
systemctl enable docker
