From the version 2.0 VirtualBox supports 32 and 64bit host and guest operating systems. If you want to install 64bit guests then your processor must support hardware virtualization and, of course, the host operating system must be 64bit as well.

VirtualBox is released under GPL v2 and Oracle VM VirtualBox extension pack is released under PUEL (Personal Use and Evaluation License).

How To Install MySQL on Ubuntu 16.04

MySQL is an open-source database management system, commonly installed as part of the popular LAMP(Linux, Apache, MySQL, PHP/Python/Perl) stack. It uses a relational database and SQL (Structured Query Language) to manage its data.
The short version of the installation is simple: update your package index, install the mysql serverpackage, and then run the included security script.
sudo apt-get update
sudo apt-get install mysql-server
mysql_secure_installation
This tutorial will explain how to install MySQL version 5.7 on a Ubuntu 16.04 server. However, if you're looking to update an existing MySQL installation to version 5.7, you can read this MySQL 5.7 update guideinstead.

Steps for Installation

You will need to follow the following steps:

STEP 1 : Installing MySQL

On Ubuntu 16.04, only the latest version of MySQL is included in the APT package repository by default. At the time of writing, that's MySQL 5.7 To install it, simply update the package index on your server and install the default package with apt-get.
sudo apt-get update
sudo apt-get install mysql-server

You'll be prompted to create a root password during the installation. Choose a secure one and make sure you remember it, because you'll need it later. Next, we'll finish configuring MySQL.

STEP 2 : Configuring MySQL

For fresh installations, you'll want to run the included security script. This changes some of the less secure default options for things like remote root logins and sample users. On older versions of MySQL, you needed to initialize the data directory manually as well, but this is done automatically now.
Run the security script.
mysql_secure_installation
This will prompt you for the root password you created in Step 1. You can press Y and then ENTER to accept the defaults for all the subsequent questions, with the exception of the one that asks if you'd like to change the root password. You just set it in Step 1, so you don't have to change it now. For a more detailed walkthrough of these options, you can see this step of the LAMP installation tutorial.

STEP 3 : Testing MySQL

Regardless of how you installed it, MySQL should have started running automatically. To test this, check its status. You'll see output similar to the following:


In case, if You'll not see output similar to the above. Please try
sudo mysql_secure_installation
Thats it....Lets Enjoy..... 😆

How to fix sudo after “chmod -R 777 /usr/bin”?

Today, by mistakenly, I set the 'sudo chmod -R 777' to my /usr/bin folder as a root user. After doing that, I found that , my sudo command was not working at all. After spending a couple (of) hours over google, finally I got the solution and here I am going to share with you.

In an attempt to set permissions for my local scripts(because as I told you ,I broke the sudo permission and changed ownership, by mistake ), and back the ownership of sudo to root , I followed the following steps:
Step 1: Switch to ubuntu recovery mode. If you are unaware of the process, you can refer an answer here: https://brajeshnotes.blogspot.com/2018/10/how-can-i-start-ubuntu-in-safe-mode.html
Step 2: Once in recovery mode, select root - Drop to root shell prompt

Step 3: Do the following commands.
mount -o remount,rw /
chown root:root /usr/bin/sudo
chmod 4755 /usr/bin/sudo
reboot
Note*: If after reboot , sudo comes up with the same three errors mention below :  

sudo: error in /etc/sudo.conf, line 0 while loading plugin 'sudoers_policy'
sudo: /usr/lib/sudo/sudoers.so must only be writable by owner
sudo: fatal error, unable to load plugins.

Try this :
$ mount -o remount,rw /
$ chmod 644 /usr/lib/sudo/sudoers.so
reboot
Wait for your system to boot normally and you will see the ownership of sudo back to root.After doing these all steps, still you guys facing any problem, please leave your valuable comments here, I will try to answer my best.
