Configure ssh password free login

Turn off iptables and firewalld services on each node

disable SELinux

Disable Swap devices

Enable iptables bridging and routing forwarding

III. Deploying k8s clusters

deploy Docker

Deploying Kubernetes

Configure Master Node Initialization

download

yum -y install chrony

start

systemctl start chronyd && systemctl enable chronyd

detection

chronyc sources

Complete the name resolution of each node through DNS, test the environment host, and replace it with the hosts file.

hostnamectl set-hostname master

Set node01 and node02 similarly

Configure each node hosts

Configure master configure ssh password free login.

ssh-keygen -t rsa

ssh-copy-id node01

ssh-copy-id node02

If there is a firewalld service or iptables rule, close the iptables and firewalld services of each node.

systemctl stop firewalld && systemctl disable firewalld

iptables -F

disable SELinux

Close Temporary

setenforce 0

permanently closed

/etc/sysconfig/selinux Change SELINUX=disabled

Disable Swap devices

check

swapoff -a

free

Enable iptables bridging and routing forwarding

Each node opens the bridge.

sysctl -a |grep bridge Filter bridge does not exist Use the following command to load br_netfiltermodprobe br_netfiltercat >> /etc/sysctl.d/k8s.conf > /etc/sysctl.confsysctl -p

III. Deploying k8s clusters

deploy Docker

Get yum, install, open.

wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo -O /etc/yum.repos.d/docker-ce.repoyum -y install docker-cesystemctl enable docker && systemctl start dockerdocker --version

Deploying Kubernetes

Get yum.

cat > /etc/yum.repos.d/kubernetes.repo
