In this guide, we will walk you through the process of setting up Tomcat server on your CentOS system using a convenient shell script. In the command above, we have added the inventory file with the "-i" option, followed by the playbook path.Welcome to the blog on installing and configuring Tomcat server! Now, to run the playbook, type the following command on the controller node:Īnsible-playbook -i /home/admin/inventory /home/admin/install-nginx.yml Make sure to use consistent spacing for your YAML file to avoid errors. Note: Prioritize using only spaces and not tabs. We can save this playbook into a file called something like "nginx.yml". The handler will execute after the nginx web server is installed.

The code above defines the "start nginx" handler. Handlers are the same as hosts and tasks, but they operate only when instructed by a task on the client system. Here, ‘notify’ consists of a list with one item, which is called "start nginx." Notify is not an internal command of Ansible but a reference to a handler that is responsible for performing a function when it is called by a task. Task performs all the major operations in the file. In this playbook, we have a set of tasks, such as: The YAML file defines a hierarchical structure with the containing elements such as hosts, tasks, and handlers. YAML provides multiple files to exist in one document file where each is separated by. Let’s break the code into segments for a better understanding. Now, go to the insert mode and add the following text to your playbook.Īpt: name: nginx state: started update_cache: true These playbooks are written in YAML language which is human-readable (as shown below). Here, we will create a simple Ansible playbook by installing Nginx on the Managed Node.įirst, log onto your Controller Node as the “Simplilearn” user and create a file with a descriptive name.

Now, enter ‘i’ to get to the insert mode, and add the hostname of the Managed Node. Log in to your control node as the admin user to connect the Managed node to the inventory.
Ssh-copy-id node.kb. Step 6: Create an InventoryĪn inventory list is created to identify your managed nodes. Then, copy the public key and paste it to our Managed node with the command below. Now, run the following command (in the control node) to generate an SSH key pair. Then, ensure that you set up an SSH key pair to the Simplilearn user. Simplilearn user) so that it can access the Managed node without a password. Passwd Step 5: Configure Our Admin User for SSH AccessĬonfigure the admin user (i.e.

Passwd the admin user, and set a password onto your Managed node. Also, you should ensure that you use the same username on both the nodes (i.e., controller node and your managed node).Īdd a user and set a password onto your Controller node.
In this demo, we will use "Simplilearn"' as the username (but any username can be added). Let's create a non-root user on both the nodes that will run our Ansible playbooks. Yum install ansible Step 4: Create a User for Ansible The next step is to install the Ansible package from the EPEL repository. Moving on, install the EPEL repository on the system.ĮPEL provides easy access to install commonly used packages on CentOS.

Yum update Step 2: Install EPEL Repository
Enter the command mentioned below to start your task. Step 1: Update Your Control Nodeīefore installing any new software, it is important to ensure that your existing operating version is up-to-date. Now, let's get started on this and understand the Ansible installation process in detail. Let's name our first machine, as ‘Server’ that will act as our managed node, and the second machine named ‘Node’ that will act as the controller node. While installing Ansible, it's essential to have two machines.
