1. Upgrading to an unslotted MySQL version from a slotted one
Due to the negative response from our user base, the MySQL team has decided to go back to unslotted MySQL. In other words, installing different versions of MySQL on the same system is not supported anymore.
If you had upgraded to the slotted version, this guide should help you upgrade to the unslotted version.
The following script should do most of the work:
Code Listing 1.1: "Unslotting" script |
echo " building an unslotted copy of mysql "
emerge --buildpkgonly '=dev-db/mysql-5.0.18-r60'
echo " stopping the server "
/etc/init.d/mysql stop
echo " removing most of symlinks "
eselect mysql remove
echo " config files "
mv /etc/mysql /etc/mysql.old
mv /etc/mysql-500 /etc/mysql
echo " removal of remaining symlinks, and eselect stuff "
rm /usr/lib/mysql /usr/include/mysql /usr/bin/mysql_config /usr/lib/libmysql*
rm -rf /var/lib/eselect/mysql/ /usr/lib/mysql-[45]0[01]
echo " unmerge slotted mysql "
emerge -C \
=dev-db/mysql-4.0.26-r30 \
=dev-db/mysql-4.1.15-r30 \
=dev-db/mysql-4.1.16-r30 \
=dev-db/mysql-4.1.18-r30 \
=dev-db/mysql-5.0.15-r30 \
=dev-db/mysql-5.0.16-r30 \
=dev-db/mysql-5.0.17-r30 \
=dev-db/mysql-5.0.18-r30 \
=dev-db/mysql-5.1.3_alpha-r30 \
=dev-db/mysql-5.1.4_alpha-r30 \
=dev-db/mysql-5.1.6_alpha-r30 \
app-admin/eselect-mysql
echo " ready to merge again MySQL "
emerge --usepkgonly '=dev-db/mysql-5.0.18-r60'

It is also recommended that you move data directories listed in /etc/mysql/my.cnf. If you do that, don't forget to edit /etc/mysql/my.cnf as well.
