ansible训练五

作业： 在ansible节点中新建/home/student/ansible/hwreport.empty的文件，文件内容为 hostname:

inventoryhostname mem: memory_in_MB bios: BIOS_version sda: disk_sda_size 创建一个名为 /home/student/ansible/hwreport.yml的 playbook，它将在所有受管节点上生成含有以 下信息的输出文件 /root/hwreport.txt：

输出文件中的每一行含有一个 key=value 对您的 playbook 应当：

从 ansible节点中复制hwreport.empty文件到每台受控主机，并将它保存为/root/hwreport.txt 使用正确的值修改 /root/hwreport.txt 然后将/home/student/ansible/hwreport.yml这个playbook进行加密，加密的密码保存 在/home/student/ansible/pass文件中，密码为abcdefg 执行该playbook，实现需求

# 创建hwreport.empty
[student@ansible ~/ansible]$cat hwreport.empty
hostname:inventoryhostname
mem:memory_in_MB
bios:BIOS_version
sda:disk_sda_size
# 创建hwreport.yml
[student@ansible ~/ansible]$ansible-vault view hwreport.yml

# 加密 playbook
[student@ansible ~/ansible]$vim pass

[student@ansible ~/ansible]$ansible-vault encrypt hwreport.yml --vault-id pass
Encryption successful
# 执行playbook
[student@ansible ~/ansible]$ansible-playbook hwreport.yml --vault-id pass
