安装nfs(全部节点均需)

yum install nfs-utils -y
vim /etc/exports

/root/news/nfs  *(insecure,rw,sync,no_root_squash)

# *: 任意用户均可接入,可修改成10.0.0.0/16,表示该网段用户均可接入
# insecure: 端口不仅限制于(0,1024]
# sync: 所有用户在请求时写入共享
# no_root_squash: root用户具有全部权限

systemctl restart nfs-server
systemctl enable nfs-serverl

#查看挂载信息
showmount

部署zookeeper

一下配置文件经过修改，具体就是将zk跑在ubuntu上，然后再将对应目录挂载，且kubernetes-zookeepr也经过修改，避免了UnKnonwnHostException错误；
