# master集群部署
```shell
1.下載https://github.com/kubernetes/kubernetes/releases 至/root/
# tar -xvf kubernetes-src.tar.gz
# cp server/bin/kube-apiserver /opt/kubernetes/bin/
# cp server/bin/kube-controller-manager /opt/kubernetes/bin/
# cp server/bin/kube-scheduler /opt/kubernetes/bin/
2.編輯apiserver.sh
# vim apiserver.sh
#!/bin/bash
#master主機IP地址
MASTER_ADDRESS=${1:-"192.168.11.212"}
#etcd集群地址
ETCD_SERVERS=${2:-"https://192.168.11.212:2379,https://192.168.11.213:2379,https://192.168.11.214:2379"}

4.編輯controller-manager.sh

systemctl enable kube-controller-manager
systemctl restart kube-controller-manager
5.安裝master上組件
# ./apiserver.sh
# ./scheduler.sh
# ./controller-manager.sh
6.驗證集群狀態
# kubectl get cs
```
