角色 | 地址 | 安裝組件 |
---|---|---|
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 |
分隔符前的操作均在master01上進(jìn)行
復(fù)制kubernetes目錄到master02
[root@master k8s]# scp -r /opt/kubernetes/ root@192.168.142.120:/opt
復(fù)制etcd目錄到master02
master02一定要有etcd證書(shū),否則apiserver服務(wù)無(wú)法啟動(dòng)
[root@master k8s]# scp -r /opt/etcd/ root@192.168.142.120:/opt
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/
實(shí)際上僅需要修改apiserver即可
[root@master02 k8s]# cd /opt/kubernetes/cfg/
[root@master02 cfg]# vim kube-apiserver
