2. 部署
2.1 服务器初始化
基础软件安装
yum install vim net-tools git -y
关闭selinux
编辑 /etc/sysconfig/selinux SELINUX=disabled
关闭firewall防火墙
systemctl disable firewalld && systemctl stop firewalld
更新服务器后重启
yum update -y && reboot
修改内核参数
创建/etc/sysctl.d/k8s.conf文件
net.bridge.bridge-nf-call-ip6tables = 1 net.bridge.bridge-nf-call-iptables = 1 sysctl -p /etc/sysctl.d/k8s.conf # 生效
2.2 kubeadm，kubectl，kubelet ，docker 安装
2.2.1 添加yum源
创建/etc/yum.repos.d/k8s.repo文件
[kubernetes] name=Kubernetes baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/ enabled=1 gpgcheck=1 repo_gpgcheck=1 gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
2.2.2 安装
yum install kubeadm kubectl kubelet docker -y systemctl enable docker && systemctl enable kubelet
2.3 导入docker镜像
