Instructions to Use (For Linux-Ubuntu Users)

Lets first create a keypair by logging into our amazon console. Remember the name of the keypair. We will use the created keypair to ssh into ec2 instances.

Next lets setup the credentails which we will use to provision resources. You need the access_key and secret_access_key Create a folder name .aws in your home directory, using the following command

mkdir ~/.aws/

Next create credentails file in ~/.aws/ folder, using

touch credentails

Now lets add our keys to the credentials file. Replace your_access_key and your_secret_access_key with the keys provided to you. Add these lines in your credentials file.

[default]
aws_access_key_id=your_access_key
aws_secret_access_key=your_secret_access_key

Now lets download this repository. Run

git clone https://github.com/ajinkyakadam/deploy-wordpress-aws.git

Add the following to file /etc/ansible/hosts

[local]
localhost

Then,

cd deploy-wordpress/

and provision the stack run the following,

ansible-playbook -i /etc/ansible/hosts deploy-wp.yml --verbose

Once the stack creation is complete open your browser and goto (replace WebServerPublicIp with your WebServers IP)

http://WebServerPublicIp/wordpress/wp-admin/install.php

You will see the setup page as below

Next, after you select the language of your choice, enter your details
