NFS–network file system 可以在linux/unix系统之间共享，支持多节点同时挂载以及并发写入。如果大家有那种web集群（httpd/tomcat/nginx），可以用nfs挂载，方便管理网页信息
我写了一个yml文件，供参考
1 安装ansible，配置inventory
yum -y install ansible
2 建立一个***.yaml 文件，位置我放在了root下
复制该文本请记得修改挂载点的 ip，nfs_info目录位置随意，但它下面的文件index.html 中后缀不可以出错。
vim nfs.yml

3 ansible执行剧本
ansible-playbook nfs.yml #执行上面的剧本，具体名字根据剧本名字来 ansible all -m shell -a 'lsblk' ansibel all -m shell -a 'df -Th' # 查询挂载是否成功
