Learn how to install a MySQL external database for NiFi Registry.

For a list of supported MySQL databases, see Supported NiFi Registry databases.
- Log in to the node on which you want to install NiFi Registry.
Install MySQL and the MySQL community server, and start the MySQL
yum localinstall https://dev.mysql.com/get/mysql[***MYSQL_VERSION***]-community-release-el[***RHEL_VERSION***]-[***PACKAGE_VERSION***].noarch.rpm yum install mysql-community-server systemctl start mysqld.service
You can replace the placeholders with the appropriate values for your specific use case:
For example, if you want to install the MySQL 8.0 Community Edition repository configuration package on a RHEL 8 system, you would use:
- [***MYSQL_VERSION***]: Replace this with the desired MySQL version.
- [***RHEL_VERSION***]: Replace this with the Red Hat Enterprise Linux (RHEL) version you are using.
- [***PACKAGE_VERSION***]: Replace this with the specific package version.
yum localinstall https://dev.mysql.com/get/mysql80-community-release-el8-8.noarch.rpm
Obtain the randomly generated MySQL root password:
grep 'A temporary password is generated for root@localhost' \ /var/log/mysqld.log |tail -1
Reset the MySQL root password.
Enter the following command:
You are then prompted for the password you obtained in the previous step. MySQL then asks you to change the password.
Once you have completed the MySQL installation, configure it for use with NiFi Registry.
