How to upgrade mysql with custombuild

To upgrade mysql using the custombuild script, do the following:

cd /usr/local/directadmin/custombuild

Edit the options.conf file. Set:

mysql=5.1
mysql_inst=yes
mysql_backup=yes

Where mysql= can be 5.1, 5.0 or 4.1.

Save/exit, then type:

./build mysql

A full raw sql backup will be run prior to the upgrade if you have mysql_backup=yes set. It goes without saying, always make backups, either with this tool, or with other means.

After the mysql update, always recompile php.

./build php n
