| 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 |
分隔符前的操作均在master01上进行
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:/optkube-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/实际上仅需要修改apiserver即可
[root@master02 k8s]# cd /opt/kubernetes/cfg/
[root@master02 cfg]# vim kube-apiserver
