这篇文章主要介绍K8S多master中如何部署Master02，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！

服务器角色分配

角色	地址	安装组件
master	192.168.142.220	kube-apiserver kube-controller-manager kube-scheduler etcd
master02	192.168.142.120	kube-apiserver kube-controller-manager kube-scheduler
node1	192.168.142.136	kubelet kube-proxy docker flannel etcd
node2	192.168.142.132	kubelet kube-proxy docker flannel etcd
nginx1	192.168.142.130	nginx keepalived
nginx2	192.168.142.140	nginx keepalived

一、Master02配置

分隔符前的操作均在master01上进行

复制目录到master02

复制kubernetes目录到master02

[root@master k8s]# scp -r /opt/kubernetes/ root@192.168.142.120:/opt

复制etcd目录到master02

master02一定要有etcd证书，否则apiserver服务无法启动

[root@master k8s]# scp -r /opt/etcd/ root@192.168.142.120:/opt

复制服务启动脚本

kube-apiserver.service kube-controller-manager.service kube-scheduler.service

[root@master k8s]# scp /usr/lib/systemd/system/{kube-apiserver,kube-controller-manager,kube-scheduler}.service root@192.168.142.120:/usr/lib/systemd/system/

修改服务脚本

实际上仅需要修改apiserver即可

[root@master02 k8s]# cd /opt/kubernetes/cfg/[root@master02 cfg]# vim kube-apiserverKUBE_APISERVER_OPTS="--logtostderr=true \--v=4 \--etcd-servers=https://192.168.142.220:2379,https://192.168.142.136:2379,https://192.168.142.132:2379 \#注意地址更改--bind-address=192.168.142.120 \--secure-port=6443 \#注意地址更改--advertise-address=192.168.142.120 \--allow-privileged=true \--service-cluster-ip-range=10.0.0.0/24 \--enable-admission-plugins=NamespaceLifecycle,LimitRanger,ServiceAccount,ResourceQuota,NodeRestriction \--authorization-mode=RBAC,Node \--kubelet-https=true \--enable-bootstrap-token-auth \--token-auth-file=/opt/kubernetes/cfg/token.csv \--service-node-port-range=30000-50000 \--tls-cert-file=/opt/kubernetes/ssl/server.pem  \--tls-private-key-file=/opt/kubernetes/ssl/server-key.pem \--client-ca-file=/opt/kubernetes/ssl/ca.pem \--service-account-key-file=/opt/kubernetes/ssl/ca-key.pem \--etcd-cafile=/opt/etcd/ssl/ca.pem \--etcd-certfile=/opt/etcd/ssl/server.pem \--etcd-keyfile=/opt/etcd/ssl/server-key.pem"

开启服务

[root@master02 cfg]# systemctl start kube-apiserver.service [root@master02 cfg]# systemctl start kube-controller-manager.service [root@master02 cfg]# systemctl start kube-scheduler.service

结果验证

//增加环境变量[root@master02 cfg]# vim /etc/profile//末尾添加export PATH=$PATH:/opt/kubernetes/bin/[root@master02 cfg]# source /etc/profile//见到如下画面即为成功[root@master02 cfg]# kubectl get nodeNAME              STATUS   ROLES    AGE     VERSION192.168.142.132   Ready       2d12h   v1.12.3192.168.142.136   Ready       38h     v1.12.3
