This document provides instructions for setting up a virtual MySQL 5.7 environment using VirtualBox and CentOS 7. It outlines downloading and installing the necessary software components of VirtualBox, CentOS 7, and MySQL 5.7 binaries. It then guides setting up a virtual machine in VirtualBox, installing CentOS as the guest operating system, and finally installing and configuring MySQL 5.7 on the virtual CentOS machine. Key steps include creating virtual hard disks, configuring networks, installing MySQL from binaries, setting up user accounts and file permissions, and testing the MySQL connection.

1. MYSQL 5.7
BUILD YOUR VIRTUAL ENVIRONMENT

2. THE NECESSARY COMPONENTS
VirtualBox MySQL 5.7 CENTOS 7.0
www.virtualbox.org dev.mysql.com www.centos.org

3. ENVIRONMENT OVERVIEW
MY
LAPTOP
IP =
192.168.122.20

4. HOW IT LOOKS

5. HOW IT WORKS
Start MySQL

9. LET’S START

10. LET’S FINISH
The Oracle VM Virtual Manager will open.

11. <OBTAIN A CENTOS IMAGE>
TO INSTALL CENTOS IN VIRTUALBOX, FIRST WE
NEED AN INSTALLATION IMAGE OR DISC.
WHILE VIRTUALBOX ALLOWS YOU TO CONNECT TO
A SYSTEM'S OPTICAL DRIVE, TO INSTALL FROM A CD
OR DVD, THE PROCESS WE'LL GO THROUGH IN THIS
VIDEO USES AN ISO IMAGE.
IT IS A FILE THAT REPRESENTS THE CONTENTS OF AN
INSTALLATION DISC.

12. SELECT THE FOLDER FOR VIRTUAL DISKS

13. CREATE VIRTUAL MACHINE
Click on new button Specify the name and OS

14. SET UP HARDWARE
Memory Display

15. VIRTUAL DISK, STEP I
Select “Create a virtual hard
disk now” and click “Create”
Choose "VDI“ (VirtualBox Disk
Image) and click "Next"

16. VIRTUAL DISK, STEP II
Specify "dynamically allocated"
and click “Next”
Type the disk name and specify
volume size

17. VIRTUAL DISK, STEP III

port forwarding
• Click <Port forwarding> button inside “NAT
Network details” dialog window
• Click <Add new rule> button
• Specify:
Rule name - ssh-MYSQL
Protocol - TCP
Host IP – leave it blank
Host port – 2222

23. CHANGE HOST NAME
Set the new name
• echo vm-mysql > /etc/hostname
Assign IP to new local name
• echo “127.0.0.1 vm-mysql” >> /etc/hosts

24. CREATE USER FOR REMOTE LOGIN
Add necessary groups
• groupadd --gid 444 vtvadm
Create user
• useradd -m -d /home/vtvadm -s /bin/bash -c "VM Administrator"
-u 444 -g vtvadm -G wheel,vboxsf vtvadm

31. PREINSTALLATION TASKS
Check dependency
• MySQL has a dependency on the libaio library.
• For Non-Uniform Memory Access (NUMA) MySQL requires he libnuma library.
[root@vm-mysql local]# yum list installed | egrep -i "libaio|libnuma"
libaio.x86_64 0.3.109-13.el7 @anaconda
[root@vm-mysql local]#

32. UNPACK THE DISTRIBUTION
Pick the necessary directory
