FreeBSD: Upgrading mysql40-server to a higher version port
Posted on November 28th, 2007 1 commentHad a need to upgrade MySQL 4.0.27 on one of the productions servers I manage to MySQL 5.0. If anyone has any trouble doing that, I have written a small tutorial on how to accomplish this task without many problems.
Note!
A small reminder. Since we’re going to use the ports system to install/upgrade our new MySQL Server daemon, i would suggest you have your ports tree up to date, and specify your MAKE options in /etc/make.conf (can come in handy when you update your port though portupgrade).Step 1 – Backup your database
Just in case you ran into any problem, I would strongly suggest you to make a backup so you can roll back any time to mysql40-server.# cd /var/db # tar cvfz mysql.tar.gz mysql
You will end up with an archive of the whole MySQL database folder.
Step 2 – Stop the service
# /usr/local/etc/rc.d/mysql-server.sh stop
Step 3 – Remove the old MySQL Server.
# pkg_delete mysql-server-4.0.27 # pkg_delete mysql-client-4.0.27
The error you might get here is only the one telling you that some ports require mysql40-client in order to function. These ports might include phpMyAdmin, php4-mysql & php5-mysql, etc. Act accordingly, either remove the ports, or use pkg_delete -f to force removal of mysql40-server.
Step 4 – Install the new MySQL Server.
# cd /usr/ports/databases/mysql50-server && make install clean
This step will take some time, depending on your internet connection speed and your server’s hardware in general.
Step 5 – Start MySQL 5.0 and run the upgrade script
# /usr/local/etc/rc.d/mysql-server.sh start # /usr/local/bin/mysql_upgrade -u root -p --datadir=/var/db/mysql
Enter your root password on prompt and enjoy the upgrade script output.
If everything went nice and smooth, you should be now running a properply upgraded mysql server 5.0.
As a final note, ports like php4-mysql, php5-mysql and others that have been build according to your previous MySQL version have to be re-installed.
