[root@k8s-master software]# systemctl start etcd.service
Job for etcd.service failed because the control process exited with error code. See "systemctl status etcd.service" and "journalctl -xe" for details.

 按照提示输入 systemctl status etcd 和 journalctl -xe 查看 

Failed to start Etcd Server.     启动Etcd Server失败。

很明显他说了废话

 提示没有etcd

[root@k8s-master software]# cd /opt/kuberneters/bin/
[root@k8s-master bin]# ls
etcd  etcdctl

 可以看到文件是有的

查看主配置文件 vim /opt/kubernetes/cfg/etcd

 查看脚本文件

 复制脚本里的目录查看发现   没有文件或目录 机智的我发现 原来是kubernetes 写成了 kuberneters

 

 再次启动 就可以启动成功了
