MySQL : Upgrade MySQL 5.6 to 5.7

This report summarizes the actions necessary to carry out an in-place update of MySQL 5.6 to 5.7. There are quite a few requirements and caveats related to this procedure, which means you need to confirm the documentation before trying an update.

Do a clean shutdown of the mysqld support.

# mysql --user root --password --execute="set global innodb_fast_shutdown=0"
# service mysqld stop

Take a physical copy at this time. This will let you recovery if anything fails. Additionally, have a copy of your “/etc/my. cnf” file.

You must get a great backup and exercise your restoration situation before attempting this. When something goes wrong, you will likely have to reinstall MySQL 5.6 and reestablish your database before trying again. You’ll need copies to get this done!

Install the MySQL 5.7 repository and then use YUM to upgrade the binaries.

# rpm -Uvh /tmp/mysql57-community-release-el6-7.noarch.rpm
# yum update mysql-community-server -y

The setup of this repository bundle fails with dependency errors, then delete the present applications and set up the newest new edition.

# yum remove mysql-community-server -y
# rpm -Uvh /tmp/mysql57-community-release-el6-7.noarch.rpm
# yum install mysql-community-server -y

This provides all of the packages on it, in order the next will be upgraded.

  • mysql-community-server
  • mysql-community-client
  • mysql-community-common
  • mysql-community-libs
  • mysql-community-libs-compat
  • Start the mysqld service.
# service mysqld start

Update database by conducting the mysql upgrade command. Before you do so, you may want to divert the output into your script, so it is possible to check for mistakes.

# mysql_upgrade --password

Assess the “/tmp/upgrade.txt” document for mistakes. When that’s OK, the update is now complete. It might make sense to choose an additional backup now.
