How to Deploy the Web Server In Ansible
To Deploy the Web Server In Ansible
Introduction:
Ansible is an open-source automation platform that manages software installations, updates, configurations, and tasks within your network environment.
A web server is a computer that runs websites. It's a computer program that distributes web pages as they are requisitioned. The basic objective of the web server is to store, process and deliver web pages to the users. A Domain Name Server (DNS) converts this URL to an IP Address
Check the Os version by using following command:
[root@linuxhelp ~]# lsb_release -d
Description: CentOS Linux release 7.6.1810 (Core)
Install httpd server:
[root@linuxhelp ~]# yum install httpd

Add the firewall service:
[root@linuxhelp ~]# firewall-cmd --permanent --add-service=http
success
Reload the firewall:
[root@linuxhelp ~]# firewall-cmd --reload
success
Start the apache server:
[root@linuxhelp ~]# systemctl start httpd
Check the status of the apacheche service
[root@linuxhelp ~]# systemctl status httpd

Create a directory:
[root@linuxhelp ~]# mkdir webserver
Switch to webserver directory:
[root@linuxhelp ~]# cd webserver/
Open yaml file:
[root@linuxhelp webserver]# vi main.yaml
Open hosts file:
[root@linuxhelp webserver]# vi hosts
Configure the ansible.config file:
[root@linuxhelp webserver]# vi ansible.cfg
Check the syntax of the main.yaml file:
[root@linuxhelp webserver]# ansible-playbook main.yaml --syntax-check
playbook: main.yaml
Execute the main file:
[root@linuxhelp webserver]# ansible-playbook main.yaml

With this method, Deploy webserver in Ansible comes to an end.
Q
How does a client-server work?
A
Clients, taking the form of laptops, desktops, tablets, or smartphones, then request a file or application from the remote server. The server hears the request, verifies credentials, and if everything checks out, serves the client the requested file. The communication between clients and servers is a two-way street.
Q
What is Playbook?
A
The real power of Ansible, however, is in learning how to use playbooks to run multiple, complex tasks against a set of targeted hosts in an easily repeatable manner.
Q
What is the most used Web server?
A
Apache
We'll dive into Apache first since it was released first. After Tim Berners-Lee's CERN HTTPd and NCSA HTTPd in the first couple of years of the internet, Apache – first released in 1995 – quickly conquered the market and became the world's most popular web server.

Q
What is the function of a web server?
A
A web server is a software and hardware that uses HTTP (Hypertext Transfer Protocol) and other protocols to respond to client requests made over the World Wide Web. The main job of a web server is to display website content through storing, processing, and delivering webpages to users.
