2. Ansible module - command
   

   Example: Run command to get ip address from remote server
   Execute below command from shell-master node, ansible will post the command to specified inventory node for execution:

   ansible webservers -m command -a "ip addr"

   

3. Ansible module - copy
   

   [root@shell-master ~]# ansible-doc -s copy
   - name: Copy files to remote locations

   Example: Copy local file to remote target server

   First we create 1 simple file on shell-master
   
   Then using Ansible copy module copy it to remote server
   

   [root@shell-master ~]# ansible webservers -m copy -a "src=copy-to-remote.txt dest=/tmp/ mode=755 owner=wayne"

   

   Once the command finished, login back to shell-node1 check if the file been copied to required location as required:
   

4. Ansible module - file
   

   [root@shell-master ~]# ansible-doc -s file
   - name: Manage files and file properties

   Example: Let's update the file attribute we just copied to remote server from step 3
   Run below command, to change the file's owner from wayne to root, change the access mode from 755 to 777

   [root@shell-master ~]# ansible webservers -m file -a "path=/tmp/copy-to-remote.txt owner=root mode=777"

   

   After the command done for running, go back to shell-node1, verify if the file properties been updated:
