Ansible Exercise

• Write an Ansible Playbook for deploying an apache server in the ubuntu instance and installing php
• Refer Here for the documentation (skip mysql)
• Manual Steps

sudo apt update
sudo apt install apache2 -y
sudo apt install php libapache2-mod-php php-mysql -y
# create a file in the path /var/www/html/info.php with content
# <?php phpinfo( ); ?>
sudo systemctl enable apache2
sudo systemctl start apache2

• Refer Here for the playbook developed in the class. Execute this playbook by copying playbook and info.php file on ansible control node. Add your hosts file

ansible-playbook -i hosts phpapache.yaml

• The other team also wants the same stuff but they want apache and php to run on centos7
• Manual steps for centos 7 : Refer Here

sudo yum install httpd -y
sudo yum install php php-mysql
# create a file in the path /var/www/html/info.php with content
# <?php phpinfo( ); ?>
sudo systemctl enable httpd
sudo systemctl start httpd
