Kubernetes二進制部署——多master節點集群部署

前言：

接上一篇單節點部署（1）部署多節點

部署環境

負載均衡
Nginx1:192.168.13.128/24
Nginx2:192.168.13.129/24
Master節點
master1:192.168.13.131/24 kube-apiserver kube-controller-manager kube-scheduler etcd
master2:192.168.13.130/24 kube-apiserver kube-controller-manager kube-scheduler etcd
Node節點
node1:192.168.13.132/24 kubelet kube-proxy docker flannel etcd
node2:192.168.13.133/24 kubelet kube-proxy docker flannel etcd

master02的部署

1，關閉master02防火墻

[root@master02 ~]# systemctl stop firewalld.service 
[root@master02 ~]# setenforce 0

2，從master01中復制kubernetes目錄，組件server服務到master02

[root@master01 k8s]# scp -r /opt/kubernetes/ root@192.168.13.130:/opt
##復制kubernetes目錄到master02
[root@master01 k8s]# scp /usr/lib/systemd/system/{kube-apiserver,kube-controller-manager,kube-scheduler}.service root@192.168.13.130:/usr/lib/systemd/system/
##復制master中的三個組件啟動腳本

3，修改master02中的配置文件

[root@master02 ~]# cd /opt/kubernetes/cfg/
[root@master02 cfg]# vim kube-apiserve  ##修改apiserver配置文件
--bind-address=192.168.13.130 \  ##修改地址
--secure-port=6443 \
--advertise-address=192.168.13.130 \  ##修改地址

4，在master01上拷貝已有的etcd證書給master02使用（master02一定要有etcd證書，否則apiserver服務無法啟動）

[root@master01 k8s]# scp -r /opt/etcd/ root@192.168.13.130:/opt/
##在master02中操作
[root@master02 cfg]# systemctl start kube-apiserver.service  ##開啟服務
[root@master02 cfg]# systemctl enable kube-apiserver.service 
[root@master02 cfg]# systemctl start kube-controller-manager.service 
[root@master02 cfg]# systemctl enable kube-controller-manager.service
[root@master02 cfg]# systemctl start kube-scheduler.service
[root@master02 cfg]# systemctl enable kube-scheduler.service

5，修改環境變量

[root@master02 cfg]# vim /etc/profile
export PATH=$PATH:/opt/kubernetes/bin/   ##添加環境變量
[root@master02 cfg]# source /etc/profile   ##刷新配置文件
[root@master02 cfg]# kubectl get node   ##查看群集節點信息
NAME             STATUS   ROLES    AGE   VERSION
192.168.13.132   Ready    <none>   75m   v1.12.3
192.168.13.133   Ready    <none>   55m   v1.12.3

多master節點部署完成，未完待續...
