快速部署单机版本k8s（kubernetes 1.13）

一，关闭selinux和firewalld

# setenforce 0
# systemctl stop firewalld
# sed -i 's/^SELINUX=enforcing$/SELINUX=disabled/' /etc/selinux/config
# systemctl disable firewalld

二，禁用swap

# swapoff -a

三，安装docker

这里可能会碰到yum源的问题，建议改成国内的源，速度比较快

# yum -y install yum-utils device-mapper-persistent-data lvm2
# yum-config-manager -y --add-repo https://download.docker.com/linux/centos/docker-ce.repo
# yum -y install docker-ce-18.06.3.ce-3.el7 docker-ce-cli-18.06.3.ce-3.el7 containerd.io
# systemctl start docker
# systemctl enable docker

四：将docker镜像仓库改成国内的仓库

# mkdir /etc/docker
# cat <<EOF > /etc/docker/daemon.json
{
  "registry-mirrors": [
    "https://3laho3y3.mirror.aliyuncs.com"
  ]
}
EOF
 
# systemctl restart docker

 

五：设置阿里云yum仓库并安装kubernetes组件

# cat <<EOF > /etc/yum.repos.d/kubernetes.repo
