ansible 劇本部署配置nfs

### ansible 劇本部署配置nfs

--目标

--配置nfs服務端-backup，共享目錄/playbook-backup/ 共享192.168.200.0/24 all_squash通路

```sh

01 書寫劇本流程

1）把對應的過程翻譯程指令

 a)安裝nfs

 yum install -y nfs-utils

 b)配置nfs服務端

 /playbook-backup/ 192.168.200.0/24(rw,sync,all_squash)

 mkdir -p /playbook-backup

 chown -R nfsnobody.nfsnobody /playbook-backup

 c)啟動與開機自啟動

 # systemctl enabled nfs rpcbind

 # systemctl start rpcbind nfs

 d)本地的挂載

 mount -t nfs 192.168.200.3:/playbook-backup /mnt

2）找出指令對應子產品

 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）根據子產品書寫劇本

4）測試劇本

5）正式使用

```

[root@web01 playbook]# ansible all -a 'df -h'
