Ansible Excersise : 
-------------------
Excesise 1: working with inventory 
----------------------------------
* install ansible and sshpass "ssh with arguments": 
sshpass allows you to pass password to ssh connection as an argument
	# apt-get install ansible sshpass
* please edit your ansible.cfg file to ignore the SSH authenticity checking
	# vi /etc/ansible.cfg
search for [defaults] and write this : 
[defaults]
host_key_checking = False
------
to use cowsay in ansible "for more fun" , uncomment this line : 
cow_selection=random

* open your inventory file and add your class groups as shown : 
	# vi /etc/ansible/hosts 
and add the following : 

[me]
localhost
[group1]               
pc1.sse.ws.afnog.org                               
pc2.sse.ws.afnog.org
pc3.sse.ws.afnog.org      
pc4.sse.ws.afnog.org 
     
[group2]
pc[5:8].sse.ws.afnog.org

[group3]
pc[9:12].sse.ws.afnog.org

[group4]
pc[13:16].sse.ws.afnog.org

[group5]
pc[17:20].sse.ws.afnog.org

[group6]
pc[21:24].sse.ws.afnog.org

[group7]
pc[25:28].sse.ws.afnog.org

[group8]
pc[29:32].sse.ws.afnog.org
# setting user name and password that ansible going to use for all groups

[fqdn]
pc[21:24].sse.ws.afnog.org
pc[13:14].sse.ws.afnog.org
pc[16:19].sse.ws.afnog.org
pc[7:10].sse.ws.afnog.org


[all:vars]                                                   
ansible_ssh_user=afnog                              
ansible_ssh_pass=SSE@Success! 	

# save and quit your hosts file

* Copy the Public Key
	# ssh-copy-id afnog@pcX.sse.ws.afnog.org 
* Repeat the same process for other machines you wish to login automatically with.

--------------------------------------------------
Excesise 2: working with ansible ad-hoc commands  
--------------------------------------------------
* check all my inventory hosts are ready to be managed by Ansible
 	# ansible all -m ping                    

* collect and display the discovered facts for the localhost
	# ansible localhost -m setup
	# ansible  pcX.sse.ws.afnog.org -m setup -a "filter=*ipv4“

* excute echo in remote hosts : 
	#  ansible all -m shell -a "echo hi its YourName  > /home/afnog/YourName.txt" -b

* run the uptime command on all hosts in the group 2 group
	# ansible group2 -m command -a "uptime“

* fetch hard drives utilization 
	# ansible -m command -a 'df -h’ pcX.sse.ws.afnog.org

* remove telnet package from remote servers on group1: 
 ansible group1 -m apt -a "name=telnet state=absent" -b


--------------------------------------------------
Excesise 3: working with ansible play-books  
--------------------------------------------------
create a new .yaml file with name mypcX.yaml and write tasks to:
- task to install cowsay pakage
- task to configure apache and create a new virtual host with the name wwwX.pcY.sse.ws.afnog.org.conf
- task to create a new document root directory for the new virtual host under name wwwX.pcY.sse.ws.afnog.org
- task to create a simple website in the new created document root 
---------------------------------------------
1) task to install cowsay pakage : 

	# vi mypcX.yaml 
---
- hosts: groupX
  tasks:
  - name: install COWSAY 
    become: yes
    apt:
        name: cowsay
        state: latest

save and quit then run your playbook : 
	# ansible-playbook mypcX.yaml -b
---------------------------------------------------
2) task to configure apache and create a new virtual host with the name wwwX.pcY.sse.ws.afnog.org.conf
edit your mypcX.yaml and add the folowing : 

	# vi mypcX.yaml 

  - name: Configuring Virtual-Host 
    become: yes
    template:
         src: pcX-vhost.j2
         dest: "/etc/apache2/sites-enabled/wwwX.{{ ansible_fqdn }}.conf"
    notify: restart apache2
   handlers:
   - name: restart apache2
     become: yes
     service :
        name: apache2
        state: restarted
save and quit 
create the pcX-vhost.j2 file and add the virtual host configuration : 
	# vi pcX-vhost.j2
<VirtualHost *:80>
    DocumentRoot /var/www/html/wwwX.{{ ansible_fqdn }}
    ServerName wwwX.{{ ansible_fqdn }}
</VirtualHost>


;; save and quit the file 
- now run your playbook 
	# ansible-playbook mypcX.yaml -b

-----------------------------------------------------
3) task to create a new document root directory for the new virtual host under name wwwX.pcY.sse.ws.afnog.org

	# vi mypcX.yaml 

  - name: creating the Document Root Dir
    become: yes
    file:
        path: /var/www/html/wwwX.{{ ansible_fqdn }}
        state: directory
--------------------------------------------------------
creating a new index file in your document root
	
	# vi mypcX.yaml 

  - name: creating index file : 
    become: yes
    template:
        src: index.j2
        dest: /var/www/html/wwwX.{{ ansible_fqdn }}/index.html

save and quit your file 

- create the index.j2 template and add the folowing in it "replace X with your number" ,
 just copy and paste the code : 

	# vi index.j2
; start copy from here :
