Ansible for Server Security Setup

Inventory

[staging]

hostname=<host name> ansible_ssh_host=<your server ip address> ansible_user=ubuntu  ansible_ssh_private_key_file=./host_ssh/<add your key name>

[staging:vars]
ansible_python_interpreter=/usr/bin/python3

If you use nginx server, you need to remove # of nginx-ratelimit task in site.yaml

roles:
    # - { role: nginx-ratelimit, tags: 'nginx-ratelimit'} # if you use nginx server remove "#" 
    - { role: fix-security, tags: 'fix-security' }

Create User Password

python3 createpass.py

type password and copy hash

paste to user.password (./group_var/all.yaml)

user:
  name: 'admin'
  password: 'password-hash-here'

Add Allow IP address to access ssh

Add SSH allow ip to ssh.allow_ip group_vars/all.yaml (you can add ip/network range example 192.168.1.2 or 192.168.1.1/24)

ssh:
  allow_ip: 
    - 192.168.1.2
    - 192.168.1.1/24

save your host's accessable private key at host_ssh

add your public key to host_ssh

ssh-keygen -y -f {yourkey}.pem > {yourkey}.pub

after key generate

you need to add your public key name in follow task of fix-security/task/all.yaml,

- name: Add SSH public key for "{{ user.name }}"
  become: yes
  become_user: root
  authorized_key:
    user: "{{ user.name }}"
    key: "{{item }}"
    state: present
  loop:
    - "{{ lookup('file', './host_ssh/<your public key name>.pub') }}"

After finished "restart sshd" TASK, task will fail, Don't worry it's normal because we block normal connection 😄

1. Make sure you update inventory file before running the playbook.
2. Review variables in group_vars/all.yaml,
3. Install jmespath package on the Ansible control machine

   pip install jmespath
