标签:slim   qos   version   port   epo   cache   EAP   line   ade   

yum -y install wget telnet net-tools lrzsz vim zip unzip

 

修改主机名

将master节点主机名修改为k8s-master01  node节点为k8s-node01  以这种命名规则命名即可

关闭防火墙

systemctl stop firewalld && systemctl disable firewalld
永久关闭selinux
sed -i ‘s/SELINUX=enforcing/SELINUX=disabled/‘ /etc/selinux/config;cat /etc/selinux/config
setenforce 0


vi /etc/hosts

10.1.1.100    k8s-master01
10.1.1.110    k8s-node01
 

临时关闭swap

swapoff -a

 

rm -rf /etc/yum.repos.d/*

 

cd /etc/yum.repos.d/

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

 

vi  k8s.repo

[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


安装docker

yum install -y yum-utils device-mapper-persistent-data lvm2
yum -y install docker

 

cat > /etc/sysctl.d/k8s.conf << EOF
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
EOF

sysctl -p

echo "1" > /proc/sys/net/ipv4/ip_forward

 

yum -y install kubeadm-1.15.1 kubelet-1.15.1 kubectl-1.15.1

 

systemctl restart kubelet && systemctl enable kubelet

启动不起来的话,试一下kubeadm init --image-repository registry.aliyuncs.com/google_containers --ignore-preflight-errors=Swap

查看具体报错 journalctl -u kubelet

failed to load Kubelet config file /var/lib/kubelet/config.yaml

上述报错,mkdir /var/lib/kubelet
