• MySQL has a dependency on the libaio library.
• For Non-Uniform Memory Access (NUMA) MySQL requires he libnuma library.

Build MySQL virtual enviroment
- 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
- 4. HOW IT LOOKS
- 5. HOW IT WORKS Start MySQL • VBoxManage startvm MYSQL --type headless Start work-desk • VBoxManage startvm WIN7
- 6. INSTALLING AND EXPLORING VIRTUALBOX VirtualBox.org • The VirtualBox installer is available from virtualbox.org • We could either click this big, green button or navigate over to the downloads link on the left side of the page. • Here under VirtualBox platform packages, there are the links to download installer for VirtualBox for various platforms.
- 7. DOWNLOAD Windows users • Click on <Windows hosts> labels • Select a place to save the file “VirtualBox-6.0.4-128413-Win.exe” Linux users • Click on <Linux distributions> to check available options: • Ubuntu 18.04 / 18.10 / Debian 10 • OpenSUSE 15.0 • Fedora 29 • Oracle Linux 7 / Red Hat 7 / CENTOS 7 Save the “VirtualBox-6.0-6.0.4_128413_el7-1.x86_64.rpm” file
- 8. INSTALLATION Windows users • After you download binary, it is time to install VirtualBox. • You will need to have administrator privileges in order to install the software. Linux users • Execute from command shell in terminal.• Double click on file “VirtualBox-6.0.4-128413-Win.exe” and click on “Run”.
- 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 ATTACH A CENTOS ISO IMAGE TO VIRTUAL DVD DEVICE
- 18. CENTOS VM WAS CREATED • Name: MYSQL • OS: CentOS 7.0 64-bit • RAM: 640 MB • HDD: 16GB • Video: 128 MB • Network: VIRTUAL NAT
- 19. BUILD YOUR VIRTUAL NETWORK • Click on File->Preferences, select "Network“, and click on "+ (Adds New NAT Network)“ on "NAT Networks" tab. • Click on "Edits Selected NAT Network", make sure "Supports DHCP" is enabled, and click "OK".
- 20. LOCAL PORT FORWARDING To allow an access to VM from your laptop, you need to set up the 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 Guest IP - 192.168.122.5 Guest port - 22
- 21. FIRST CENTOS RUN • Click on Machine->Start, select "Normal start“ or • Click on “Start” button Execute from command prompt in terminal • VBoxManage startvm MYSQL
- 22. LOGIN LOGIN AS ROOT USER AND PROVIDE PASSWORD, ENTERED DURING CENTOS INSTALLATION PROCEDURE
- 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
- 25. CREATE MYSQL USER Add necessary groups • grpName=mysql usrName=mysql grpID=7887 usrID=333 • groupadd --gid ${grpID} ${grpName} Creating the MySQL owner user • useradd -r -u ${usrID} -g ${grpName} -s /bin/false -c "MySQL/MariaDB owner" ${usrName}
- 26. RESTART THE VIRTUAL MACHINE Execute from command shell • sudo shutdown -r now
- 27. MYSQL INSTALLATION Remote login • ssh -p 2222 vtvadm@localhost
- 28. SWITCH INTO ROOT USER Execute from command shell • sudo su -
- 29. DOWNLOAD MYSQL BINARIES Switch into MySQL home directory • cd /usr/local Download binaries • wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.25-el7- x86_64.tar
