targets

• all project objects must run on the aws
• wordpress must run on aws Ec2
• there must be have load balancer in front of server
• database must be aws Rds

pre Requirements

• Terraform
• Ansible
• Amazon Aws Key(ec2)
• Amazon Aws IAM(AdminAccess)

Topology

s1- first clone project

git clone https://github.com/ysfduzgun/devopsHw

s2- Edit credential file - (Aws AIM)

devopsHw/terraform/credential

s3- Copy your pem and change perm. - (AWS ec2Key)

cp your_key.epm devopsHw/ansible/your_key.pem
chmod 400 devopsHw/ansible/your_key.pem

s4- Terraform stage

cd devopsHw/terraform/
terraform init
terraform plan
terraform apply
yes

now our architecture is preparing. we can check server with ping.

ping $(terraform output ubuntuIp)

when server answer to request we can go next step.

we must solve ssh fingerprint ask problem

• connect to server with ssh

cd devopsHw/ansible
ssh -i your_key.pem ubuntu@ip
The authenticity of host 'ip (ip)' can't be established.
ECDSA key fingerprint is SHA256:xyzxyzxyzxyzxyzxyzxyzxyzxyz.
Are you sure you want to continue connecting (yes/no)? yes
exit

• or disable check

touch ~/.ssh/config
echo "Host *" > ~/.ssh/config
echo "    StrictHostKeyChecking no" >> ~/.ssh/config

s5- preInstall wp environment and get some variables for ansible.

cd devopsHw/terraform
./preAnsible.sh

s6- install all wp environment and configure them

cd devopsHw/ansible/
ansible-playbook playbook.yml -i hosts.inf --private-key=./your_key.pem

sFinal-

lets request ip:6868 port, loadbalancer should have redirect to server:80

cat devopsHw/terraform/elbIp.txt

delete everything

cd devopsHw/terraform
terraform destroy
