In this tutorial. You can Build infrastructure with Vagrant ansible for testing. How to setting local server using Vagrant Ansible. Ansible the essential for DevOps Roles. Now, let’t go Vagrant Ansible example 01.
My local server
[huupv@huupv my_ansible]$ cat /etc/redhat-release Fedora release 28 (Twenty Eight) [huupv@huupv my_ansible]$ vagrant --version Vagrant 2.0.2 [huupv@huupv my_ansible]$ ansible --version ansible 2.6.4 config file = /etc/ansible/ansible.cfg configured module search path = [u'/home/huupv/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules'] ansible python module location = /usr/lib/python2.7/site-packages/ansible executable location = /usr/bin/ansible python version = 2.7.15 (default, May 16 2018, 17:50:09) [GCC 8.1.1 20180502 (Red Hat 8.1.1-1)]
Vagrant Ansible example 01
Step 1: You have to install Vagrant for your OS. If you have not to install Vagrant then ref to install Vagrant on Centos and install Vagrant on Ubuntu.
Step 2: Creating a folder and file your project.
example01/ ├── ansible.cfg ├── playbooks │ ├── inventory │ │ └── hosts │ ├── ntp.yml │ └── templates │ └── ntp.conf.j2 └── Vagrantfile 3 directories, 5 files
Step 3: Build infrastructure with Vagrant for testing. The define two servers: an app server and a database server in Vagrantfiles file.
Vagrant init create Vagrantfiles minimal file
[huupv@huupv example01]$ vagrant init --minimal
The terminal output as below
==> vagrant: A new version of Vagrant is available: 2.1.5! ==> vagrant: To upgrade visit: https://www.vagrantup.com/downloads.html A `Vagrantfile` has been placed in this directory. You are now ready to `vagrant up` your first virtual environment! Please read the comments in the Vagrantfile as well as documentation on `vagrantup.com` for more information on using Vagrant.
The content in Vagrantfile for app server and DB server as below
[huupv@huupv example01]$ cat Vagrantfile
The terminal output as below
Vagrant.configure("2") do |config|
config.ssh.insert_key = false
config.vm.provider :virtualbox do |vb|
vb.customize ["modifyvm", :id, "--memory", "256"]
end
# Application server 1.
config.vm.define "app1" do |app1|
app1.vm.hostname = "app1.dev"
app1.vm.box = "centos/7"
app1.vm.network :private_network, ip: "192.168.3.4"
end
# Database server.
config.vm.define "db" do |db|
db.vm.hostname = "db.dev"
db.vm.box = "centos/7"
db.vm.network :private_network, ip: "192.168.3.5"
end
config.vm.provision "ansible" do |ansible|
ansible.playbook = "playbooks/ntp.yml"
ansible.verbose = true
ansible.limit = "all" # or only "nodes" group, etc.
# Run commands as root.
ansible.sudo = true
end
endAnsible playbook for NTP server
Creating an inventory file for multiple servers
# Application servers [app] 192.168.3.4 # Database server [db] 192.168.3.5 # Group 'multi' with all servers [multi:children] app db # Variables that will be applied to all servers [multi:vars] ansible_ssh_user=vagrant ansible_ssh_private_key_file=~/.vagrant.d/insecure_private_key
Create a ntp.yml file in folder playbooks
- hosts: all
tasks:
- name: Ensure NTP (for time synchronization) is installed.
yum: name=ntp state=installed
- name: Configure NTP
template: src=ntp.conf.j2 dest=/etc/ntp.conf
notify:
- restart ntpd
- name: Ensure NTP is running.
service: name=ntpd state=started enabled=yesCreate ntp.conf.j2 file template

Vagrant run ansible local
Running vagrant up the first time. Vagrant automatically provisions the newly-minted VM. Run “vagrant provision” again after the VM has been created.
The first run vagrant up
[huupv@huupv example01]$ vagrant up
The terminal output as below
Run vagrant provision again.
[huupv@huupv example01]$ vagrant provision
The terminal output as below
The result Vagrant Ansible example, The terminal output as below
