What is WordPress?

WordPress is a free and open-source content management system (CMS) based on PHP and MySQL.[5] WordPress is installed on a web server that is either part of an Internet hosting service or a network host in its own right. The first case may be a service like WordPress.com, for example, and the second case could be a computer running the software package WordPress.org.[6] A local computer may be used for single-user testing and learning purposes.

WordPress has a web template system using a template processor. Its architecture is a front controller, routing all requests for non-static URIs to a single PHP file which parses the URI and identifies the target page. Once downloaded, WordPress installation files have a size of about 20 MB.

Alternative for DD command with a progress report about how much has been written-dcfldd

1 ) DD Command:-

The dd command stands for “data duplicator” and used for copying and converting data. It is very powerful low level utility of Linux which can do much more like.

• Backup and restore the entire hard disk or partition.
• Backup of MBR (Master Boot Record)
• It can copy and convert magnetic tape format, convert between ASCII and EBCDIC formats,swap bytes and can also convert lower case to upper case.
• It can also be used by Linux kernel make files to make boot images.

Only superuser can run this command because you can face a big data loss due to its improper usage, so you should be very careful while working with this utility. At that moment data loss can convert the dd utility as a “data destroyer” for you

Ansible Playbook Example-1

What’s with the Name “Ansible”?

 Ansible was used to control a large number of remote ships at once, over vast distances. Think of it as a metaphor for controlling remote servers.

Introduction:-

Ansible playbooks are a way to send commands to remote computers in a scripted way. Instead of using Ansible commands individually to remotely configure computers from the command line, you can configure entire complex environments by passing a script to one or more systems.

Ansible playbooks are written in the YAML data serialization format. If you don’t know what a data serialization format is, think of it as a way to translate a programmatic data structure (lists, arrays, dictionaries, etc) into a format that can be easily stored to disk. The file can then be used to recreate the structure at a later point. JSON is another popular data serialization format, but YAML is much easier to read.

Ansible Agentless Automation

WiKi:-

Ansible is a free-software platform for configuring and managing computers which combines multi-node software deployment, ad hoctask execution, and configuration management.[1] It manages nodes (Linux nodes must have Python 2.4 or later installed on them, Windows nodes require PowerShell 3.0 or later) over SSH or over PowerShell.[2] Modules work over JSON and standard output and can be written in any programming language. The system uses YAML to express reusable descriptions of systems.[3]

Configuration management systems are designed to make controlling large numbers of servers easy for administrators and operations teams. They allow you to control many different systems in an automated way from one central location.

setup free DDns for your home pc using no-ip and router setting for no-ip

———————-Theory——————

Dynamic DNS (DDNS or DynDNS) is a method of automatically updating a name server in the Domain Name System (DNS), often in real time, with the active DDNS configuration of its configured hostnames, addresses or other information.

Your IP address is just like your phone number, but it is your computers personal phone number on the internet. It is used by your Internet Service Providers to connect your computer to the Internet. Your computer doesn’t have the same number every day, it has a dynamic IP address, meaning it changes. It could change once a month, once a week, or even a few times a day, but it does change. Dynamic IP addresses are very common since they are cost effective for ISPs.

Setup local Environment using vagrant

Introduction:-

Vagrant is an open source tool for building a complete virtual development environment. Very often, a test environment is required for testing the latest release and new tools. Also, it reduces the time spent in re-building your OS. By default, vagrant uses virtualbox for managing the Virtualization. Vagrant acts as the central configuration for managing/deploying multiple reproducible virtual environments with the same configuration.
