Install Apache2 & NGINX on Slaves Machine using Ansible Roles — Ansible Assignment 3

Problem (1) Solution: Create 2 Ansible Roles

Step 1: Go to the “Master”. Change the directory & go to the “ansible” directory using the below-given command:

cd /etc/ansible

To view the “roles” directory, use the below-given command:

ls

Go to the “roles” directory

The “roles” directory will be found here.

Step 2: Go to the “roles” directory using the below-given command:

cd roles

Now, we will create a role “apache2” using the below-given command:

sudo ansible-galaxy init apache2

Create apache2 role

The role “apache2” has been successfully created.

Step 3: Create another role “nginx” using the below-given command:

sudo ansible-galaxy init nginx

Create NGINX role

Problem (2) Solution: Install Apache2 on slave1 using one role and NGINX on slave2 using the other role

Step 1: Go inside the role using the below-given command:

cd apache2

Go to the “apache2” role

You will land inside the role.

Step 2: Run the below-given command to check how many files & the directory are present:

ls

Go to the “tasks” folder using the below-given command:

cd tasks

Go to the “tasks” folder

Step 3: For installing apache2, we will create an “install.yaml” file using the below-given command:

sudo nano install.yaml

Create an install.yaml file

Step 4: Paste the below content in the “install.yaml” file to install apache2.

- name: installing apache2
apt: name=apache2 update-cache=yes state=latest

Install Apache2

Do “CTRL+X” to exit & Press “Yes” to save the file. Press “enter” from the keyboard to exit the file.

Step 5: Include the “install.yaml” to the “main.yaml” file here.

Run the below-given command to open the “main.yaml” file:

sudo nano main.yaml

Create a main.yaml file

Step 8: Write the below-given command here:

–include_tasks: install.yaml

Include the install.yaml file to main.yaml

Do “CTRL+X” to exit & Press “Yes” to save the file. Press “enter” from the keyboard to exit the file.

Step 10: Change the directory by running the below-given command twice:

cd ..

Go to the roles

You will notice the two roles here.

Step 11: Change the directory to nginx using the below-given command:

cd nginx

Run this command to view the directory here:

ls

You will notice the “tasks” directory.

Go to the“tasks” directory using the below-given command:

cd tasks

Go to the tasks folder

Step 12: Create an “install.yaml” file using the command:

sudo nano install.yaml

Create an install.yaml file

Step 13: Paste this command here:

- name: install nginx
apt: name=nginx update-cache=yes state=latest

Install NGINX

Do “CTRL+X” to exit & Press “Yes” to save the file. Press “enter” from the keyboard to exit the file.

Step 14: Now, add this “install.yaml” file to “main.yml”.

Write the below-given command:

-include_tasks: install.yaml

Include the install.yaml file to main.yaml

Do “CTRL+X” to exit & Press “Yes” to save the file. Press “enter” from the keyboard to exit the file.

Problem (3) Solution: The Above should be implemented using different Ansible roles

Step 1: Go to the “/etc/ansible” directory using the below-given command:

cd /etc/ansible

Create a play3.yaml file using the below-given command:

sudo nano play3.yaml

Create the play3.yaml file

Step 2: Write the file to run the script to install the given tools using the roles.

---
- name: installing apache2 on slave1
hosts: Slave1
become: true
roles:
- apache2
- name: install nginx on slave2
hosts: Slave2
become: true
roles:
- nginx

install.yaml file

Do “CTRL+X” to exit & Press “Yes” to save the file. Press “enter” from the keyboard to exit the file.

Step 3: Now, we will check the syntax of the “play3.yaml” file using the below-given command:

ansible-playbook play3.yaml --syntax-check

Syntax Check of Install.yaml file

The playbook syntax is running fine.

Step 4: Now, we will dry run of “play3.yaml” using the below-given command:

ansible-playbook play3.yaml --check

File Dry Run

Dry Run Succesful

The dry run will be successful.

Step 5: Now, we will run “play3.yaml” using the below-given command:

ansible-playbook play3.yaml

Run the play3.yaml file

Play Runned Successfully

The file will be successfully run.

Step 6: Copy the Slave1 Public IP address (35.154.71.243) into the browser address bar. Apache2 will be successfully installed.

Apache2 Installed

Step 7: Copy the Slave2 Public IP address (3.108.227.113) into the browser address bar. NGINX will be successfully installed.

NGINX Installed
