Continue running under SSH?

This session appears to be running under ssh. It is not recommended
to perform a upgrade over ssh currently because in case of failure it
is harder to recover.

If you continue, an additional ssh daemon will be started at port
'1022'.
Do you want to continue?

Continue [yN] y

Starting additional sshd

To make recovery in case of failure easier, an additional sshd will
be started on port '1022'. If anything goes wrong with the running
ssh you can still connect to the additional one.
If you run a firewall, you may need to temporarily open this port. As
this is potentially dangerous it's not done automatically. You can
open the port with e.g.:
'iptables -I INPUT -p tcp --dport 1022 -j ACCEPT'

Upgrade MySQL Server from 5.7 to 8 CentOS 7 Linux

Posted by Sriram Sanka on October 2, 2022

Quote from Mysql Website Upgrade Paths

Upgrade from MySQL 5.7 to 8.0 is supported. However, upgrade is only supported between General Availability (GA) releases. For MySQL 8.0, it is required that you upgrade from a MySQL 5.7 GA release (5.7.9 or higher). Upgrades from non-GA releases of MySQL 5.7 are not supported.
Upgrading to the latest release is recommended before upgrading to the next version. For example, upgrade to the latest MySQL 5.7 release before upgrading to MySQL 8.0.
Upgrade that skips versions is not supported. For example, upgrading directly from MySQL 5.6 to 8.0 is not supported.
Once a release series reaches General Availability (GA) status, upgrade within the release series (from one GA version to another GA version) is supported. For example, upgrading from MySQL 8.0.x to 8.0.y is supported. (Upgrade involving development-status non-GA releases is not supported.) Skipping a release is also supported. For example, upgrading from MySQL 8.0.x to 8.0.z is supported. MySQL 8.0.11 is the first GA status release within the MySQL 8.0 release series.

Reference: https://dev.mysql.com/doc/refman/8.0/en/upgrade-paths.html

Download the Required RPM and place them in the Server.

wget https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-8.0.30-1.el7.x86_64.rpm-bundle.tar

Since Mysql_upgrade is deprecated and unneeded in Version 8.0.16 and later, you can run mysql_check if needed.

[root@localhost mysql_binaries]# mysql_upgrade -uroot -p
The mysql_upgrade client is now deprecated. The actions executed by the upgrade client are now done by the server.
To upgrade, please start the new MySQL binary with the older data directory. Repairing user tables is done automatically. Restart is not required after upgrade.
The upgrade process automatically starts on running a new MySQL binary with an older data directory. To avoid accidental upgrades, please use the --upgrade=NONE option with the MySQL binary. The option --upgrade=FORCE is also provided to run the server upgrade sequence on demand.
It may be possible that the server upgrade fails due to a number of reasons. In that case, the upgrade sequence will run again during the next MySQL server start. If the server upgrade fails repeatedly, the server can be started with the --upgrade=MINIMAL option to start the server without executing the upgrade sequence, thus allowing users to manually rectify the problem.

Option 2: Follow the Below steps to Complete the Upgrade Steps

Take a backup of all the Databases & Parameter /Variable Values assigned.

Stop the Service.

Remove the Installed Old Version RPM by running rpm -qa mysql* and rpm -e <RPM_LIST>

Install the Latest Version

Restore the Backup from above

Add and Apply variable as before as supported

Conclusion : We have successfully completed the MySQL Community Server Version Upgrade on a standalone Server from 5.7 to 8.0.30
