1.rancher server 安装docker
所有主机开通ipv4
vi /etc/sysctl.conf#加入
net.ipv4.ip_forward = 1#配置生效
sysctl -p
rancher-server开通docker服务:
yum remove docker*
yum install -y yum-utils#配置docker的yum地址
yum-config-manager \--add-repo \http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo#安装最新版本
yum install -y docker-ce docker-ce-cli# 启动&开机启动docker
systemctl enable docker --now# docker加速配置
mkdir -p /etc/docker
tee /etc/docker/daemon.json <<-'EOF'
{"registry-mirrors": ["https://82m9ar63.mirror.aliyuncs.com"],"exec-opts": ["native.cgroupdriver=systemd"],"log-driver": "json-file","log-opts": {"max-size": "100m"},"storage-driver": "overlay2"
}
EOF
systemctl daemon-reload
systemctl restart docker
rancher-server 用docker运行 rancher
docker run -d --privileged -p 80:80 -p 443:443 -v /opt/data/rancher_data/:/var/lib/rancher --restart=always --name rancher rancher/rancher:v2.7.5
2.部署k8s
master:
curl -fL https://192.168.66.100/system-agent-install.sh | sudo sh -s - --server https://192.168.66.100 --label 'cattle.io/os=linux' --token 6fr2r8wwdgrxdrqlzg2g2lwl2dwwmms8g49bg54s8chtmjrd4kpd7d --ca-checksum dcb5f0234226851d165c2ea0d212506b6f560eddf84af9e6200bbac4576280f5 --etcd --controlplane --worker
node1:
curl -fL https://192.168.66.100/system-agent-install.sh | sudo sh -s - --server https://192.168.66.100 --label 'cattle.io/os=linux' --token 6fr2r8wwdgrxdrqlzg2g2lwl2dwwmms8g49bg54s8chtmjrd4kpd7d --ca-checksum dcb5f0234226851d165c2ea0d212506b6f560eddf84af9e6200bbac4576280f5 --worker

EOF#安装 kubelet，kubeadm，kubectl
sudo yum install -y kubelet#启动kubelet
sudo systemctl enable --now kubelet
于是在master节点上也可以进行命令kubectl get nodes
4.测试集群
kubectl create deployment nginx --image=nginx:alpine --replicas=2
kubectl create service nodeport nginx --tcp=80:80
curl 10.43.18.212
