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

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 
PLAY [webserver playbook] ************************************************************************************
TASK [Gathering Facts] ***************************************************************************************

TASK [install httpd] *****************************************************************************************

Check the output from client server:

[root@linuxhelp webserver]# curl http://192.168.6.111/

With this method, Deploy webserver in Ansible comes to an end.
