Upgrading to MySQL 8.0 on Windows, Mac, and Linux

Update on:
Jan 25, 2023

MySQL is one of the most popular relational database management systems in the world, and version 8.0 brings a host of new features and improvements. In this article, we’ll take a look at how to upgrade to MySQL 8.0 on Windows, Mac, and Linux.

Before You Upgrade

Before you begin the upgrade process, it’s important to make sure that your current version of MySQL is compatible with version 8.0. MySQL 8.0 is not backward-compatible with previous versions, so you’ll need to make sure that your current version is at least 5.6 or later. You can check your current version by running the following command in the MySQL command line:

mysql> SELECT VERSION();

Once you’ve confirmed that your current version of MySQL is compatible with version 8.0, you’ll need to do a bit of preparation. First, you should make a backup of your current database. This will ensure that you can easily restore your data in case something goes wrong during the upgrade process. You can do this by running the following command:

mysqldump -u [username] -p [password] [database] > [backup_file.sql]

Replace [username], [password], [database], and [backup_file.sql] with the appropriate values for your setup.

Next, you’ll want to stop the MySQL service. On Windows, you can do this by going to the Services app, finding the MySQL service, and stopping it. On Mac and Linux, you can use the following command to stop the MySQL service:

sudo service mysql stop

Upgrade on Windows

To upgrade to MySQL 8.0 on Windows, you’ll first need to download the installer from the MySQL website. Make sure to select the appropriate version for your system (64-bit or 32-bit). Once the download is complete, run the installer.

The installer will guide you through the upgrade process. It will ask you to specify the location for the new version of MySQL and will also give you the option to remove the old version. Once the installation is complete, start the MySQL service from the Services app.

Upgrade on Mac

The process for upgrading to MySQL 8.0 on Mac is a bit more involved than on Windows. First, you’ll need to download the MySQL 8.0 package from the MySQL website. Once the download is complete, open a terminal window and navigate to the location where the package is stored.

To install MySQL 8.0, you’ll need to use the following command:

sudo installer -pkg mysql-8.0.XX-macos10.XX-x86_64.pkg -target /

Make sure to replace XX with the appropriate version number.

This command will install MySQL 8.0 in the root directory.

Once the installation is complete, you’ll need to start the MySQL service using the following command:

sudo launchctl load -F /Library/LaunchDaemons/com.mysql.mysqld.plist

Upgrade on Linux

Upgrading to MySQL 8.0 on Linux is similar to the process on Mac. First, you’ll need to download the appropriate package from the MySQL website. Once the download is complete, open a terminal window and navigate to the location where the package is stored.

To install MySQL 8.0, you’ll need to use the following command:

sudo dpkg -i mysql-apt-config_0.8.14-1_all.deb

This will install the MySQL apt repository, which will allow you to easily install and upgrade to the latest version of MySQL.

Once the repository is installed, you’ll need to run the following command to upgrade to MySQL 8.0:

sudo apt-get update
sudo apt-get install mysql-server

This command will update the package list and install the MySQL 8.0 package.

Once the installation is complete, you’ll need to start the MySQL service using the following command:

sudo service mysql start

Post Upgrade Tasks

After the upgrade process is complete, you’ll want to perform a few post-upgrade tasks to ensure that everything is running smoothly.

First, you’ll want to check the status of the MySQL service to make sure it’s running correctly. You can do this by running the following command:

sudo service mysql status

Next, you’ll want to run the mysql_upgrade script to update the system tables and ensure that they are compatible with the new version of MySQL. You can do this by running the following command:

sudo mysql_upgrade -u [username] -p

Make sure to replace [username] with the appropriate value for your setup.

Finally, you’ll want to restore your backup to bring your data up to date with the new version of MySQL. You can do this by running the following command:

mysql -u [username] -p [database] < [backup_file.sql]

Make sure to replace [username], [database], and [backup_file.sql] with the appropriate values for your setup.

And that’s it! You should now be running MySQL 8.0 on your Windows, Mac, or Linux system. If you encounter any issues during the upgrade process, or have any questions about the new features in MySQL 8.0, be sure to consult the MySQL documentation or seek help from the MySQL community.
