### ansible 剧本部署配置nfs
--目标
--配置nfs服务端-backup，共享目录/playbook-backup/ 共享192.168.200.0/24 all_squash访问
```sh
01 书写剧本流程
1）把对应的过程翻译程命令
a)安装nfs
yum install -y nfs-utils
b)配置nfs服务端
/playbook-backup/ 192.168.200.0/24(rw,sync,all_squash)
mkdir -p /playbook-backup
chown -R nfsnobody.nfsnobody /playbook-backup
c)启动与开机自启动
# systemctl enabled nfs rpcbind
# systemctl start rpcbind nfs
d)本地的挂载
mount -t nfs 192.168.200.3:/playbook-backup /mnt
2）找出命令对应模块
a) yum
-m yum -a 'name=nfs-utils state=present'
b) copy
-m copy -a 'dest=/etc/exports /context="/playbook-backup/ 192.168.200.0/24(rw,sync,all_squash)"'
c) file
-m file -a 'path=/playbook-backup state=directory owner=nfsnobody group=nfsnobody '
d) systemd
-m systemd -a 'name=rpcbind enabled=yes state=started'
-m systemd -a 'name=nfs enabled=yes state=started'
e) mount
-m mount -a 'fstype=nfs src=192.168.200.3:/playbook-backup path=/mnt state=mounted'
3）根据模块书写剧本
4）测试剧本
5）正式使用
```
