The most common and easiest way of installation is through software repositories where you add official Oracle MySQL repositories to your list and install MySQL through package management software.

There are mainly two types of repository software:

• YUM (Centos, Red Hat, Fedora and Oracle Linux)
• APT (Debian, Ubuntu)

Let's look at steps for installing MySQL 8 in the following ways:

1. Find the Red Hat or CentOS version:

shell> cat /etc/redhat-release
CentOS Linux release 7.3.1611 (Core)

2. Add the MySQL Yum repository to your system's repository list. This is a one-time operation that can be performed by installing an RPM provided by MySQL.
   You can download the MySQL YUM Repository from http://dev.mysql.com/downloads/repo/yum/ and choose the file depending on your OS.
   Install the downloaded release package with the following command, replacing the name with the platform- and version-specific package name of the downloaded RPM package:

shell> sudo yum localinstall -y mysql57-community-release-el7-11.noarch.rpm
Loaded plugins: fastestmirror

3. Or you can copy the link location and install directly using RPM (you can skip the next step after installing):

shell> sudo rpm -Uvh "https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm"

   1:mysql57-community-release-el7-11 ################################# [100%]

4. Verify the installation:

shell> yum repolist enabled | grep 'mysql.*-community.*'
mysql-connectors-community/x86_64 MySQL Connectors Community                  42
mysql-tools-community/x86_64      MySQL Tools Community                       53
mysql57-community/x86_64          MySQL 5.7 Community Server                 227

5. Set the release series. At the time of writing this book, MySQL 8 is not a general availability (GA) release. So MySQL 5.7 will be selected as the default release series. To install MySQL 8, you have to set the release series to 8:

shell> sudo yum repolist all | grep mysql
mysql-cluster-7.5-community/x86_64   MySQL Cluster 7.5 Community disabled
mysql-cluster-7.5-community-source   MySQL Cluster 7.5 Community disabled
mysql-cluster-7.6-community/x86_64   MySQL Cluster 7.6 Community disabled
mysql-cluster-7.6-community-source   MySQL Cluster 7.6 Community disabled

mysql56-community-source             MySQL 5.6 Community Server  disabled
mysql57-community/x86_64             MySQL 5.7 Community Server  enabled:    227
mysql57-community-source             MySQL 5.7 Community Server  disabled
mysql80-community/x86_64             MySQL 8.0 Community Server  disabled
mysql80-community-source             MySQL 8.0 Community Server  disabled

6. Disable mysql57-community and enable mysql80-community:

shell> sudo yum install yum-utils.noarch -y
shell> sudo yum-config-manager --disable mysql57-community
shell> sudo yum-config-manager --enable mysql80-community

7. Verify that mysql80-community is enabled:

shell> sudo yum repolist all | grep mysql8
mysql80-community/x86_64             MySQL 8.0 Community Server  enabled:     16
mysql80-community-source             MySQL 8.0 Community Server  disabled

8. Install MySQL 8:

shell> sudo yum install -y mysql-community-server
Loaded plugins: fastestmirror

mysql-tools-community      | 2.5 kB  00:00:00

9. You can check the installed packages using the following:

shell> rpm -qa | grep -i 'mysql.*8.*'
perl-DBD-MySQL-4.023-5.el7.x86_64
mysql-community-libs-8.0.3-0.1.rc.el7.x86_64
mysql-community-common-8.0.3-0.1.rc.el7.x86_64
mysql-community-client-8.0.3-0.1.rc.el7.x86_64
mysql-community-server-8.0.3-0.1.rc.el7.x86_64

1. Add the MySQL APT repository to your system's repository list. This is a one-time operation that can be performed by installing a .deb file provided by MySQL
   You can download the MySQL APT repository from http://dev.mysql.com/downloads/repo/apt/.
   Or you can copy the link location and use wget to download directly on to the server. You might need to install wget (sudo apt-get install wget):

shell> wget "https://repo.mysql.com//mysql-apt-config_0.8.9-1_all.deb"

2. Install the downloaded release package with the following command, replacing  the name with platform- and version-specific package name of the downloaded APT package:

shell> sudo dpkg -i mysql-apt-config_0.8.9-1_all.deb 
(Reading database ... 131133 files and directories currently installed.)
Preparing to unpack mysql-apt-config_0.8.9-1_all.deb ...

Setting up mysql-apt-config (0.8.9-1) ...
Warning: apt-key should not be used in scripts (called from postinst maintainerscript of the package mysql-apt-config)
OK

3. During the installation of the package, you will be asked to choose the versions of the MySQL server and other components. Press Enter for selecting and the Up and Down keys for navigating.
   Select MySQL Server and Cluster (Currently selected: mysql-5.7).
   Select mysql-8.0 preview (At the time of writing, MySQL 8.0 is not GA). You might get a warning such as MySQL 8.0-RC Note that MySQL 8.0 is currently an RC. It should only be installed to preview upcoming features of MySQL, and is not recommended for use in production environments. (RC is short for release candidate).
   If you want to change the release version, execute the following:

shell> sudo dpkg-reconfigure mysql-apt-config

4. Update package information from the MySQL APT repository with the following command (this step is mandatory):

shell> sudo apt-get update

5. Install MySQL. During installation, you'll need to provide a password for the root user for your MySQL installation. Remember the password; if you forget it, you'll have to reset the root password (refer to the Resetting root password section). This installs the package for the MySQL server, as well as the packages for the client and for the database common files:

shell> sudo apt-get install -y mysql-community-server
~
Processing triggers for ureadahead (0.100.0-19) ...
Setting up mysql-common (8.0.3-rc-1ubuntu14.04) ...

Setting up mysql-community-client-core (8.0.3-rc-1ubuntu14.04) ...
Setting up mysql-community-server-core (8.0.3-rc-1ubuntu14.04) ...
~

6. Verify packages. ii indicates that the package is installed:

shell> dpkg -l | grep -i mysql
ii  mysql-apt-config            0.8.9-1               all   Auto configuration for MySQL APT Repo.
ii  mysql-client                8.0.3-rc-1ubuntu14.04 amd64 MySQL Client meta package depending on latest version
ii  mysql-common                8.0.3-rc-1ubuntu14.04 amd64 MySQL Common
ii  mysql-community-client      8.0.3-rc-1ubuntu14.04 amd64 MySQL Client
ii  mysql-community-client-core 8.0.3-rc-1ubuntu14.04 amd64 MySQL Client Core Binaries
ii  mysql-community-server      8.0.3-rc-1ubuntu14.04 amd64 MySQL Server
ii  mysql-community-server-core 8.0.3-rc-1ubuntu14.04 amd64 MySQL Server Core Binaires
