Setting up workstation for lab exercise work:

 · ansible package is installed on workstation.................  SUCCESS
 · Create exercise directory...................................  SUCCESS
 · Download Ansible configuration..............................  SUCCESS
 · Download Ansible inventory..................................  SUCCESS

执行ad-hoc命令

[student@workstation deploy-adhoc]$ ansible all -a 'id'
servera.lab.example.com | CHANGED | rc=0 >>
uid=1000(student) gid=1000(student) 组=1000(student),10(wheel) 环境=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023

指定用户执行ad-hoc命令

[student@workstation deploy-adhoc]$ ansible all -a 'id' -u devops

练习copy模块

# 替换文件内容
[student@workstation deploy-adhoc]$ ansible localhost -m copy -a 'content="Managed by Ansiblen" dest=/etc/motd' -u root

# 提权到devops执行命令
[student@workstation deploy-adhoc]$ ansible localhost -m copy -a 'content="  替换文件Managed by Ansible 这是devops创建的内容n" dest=/etc/motd' -u devops --become

# 查看替换后的文件内容
[student@workstation deploy-adhoc]$ cat /etc/motd
