- location of pid-file changed from /var/run to directory
/var/run/mysql which is owned by mysql:mysql
- added new directoy /var/log/mysql owned by mysql:mysql which
can be used to log queries
- logging of queries is now longer enabled in /etc/my.cnf
- error messages are logged to /var/log/mysqld.log
Note:
rejmerge /etc/my.conf to avoid problems due to the above changes
Note:
-----
this is a major update of mysql from version 5.5 to 5.6 and it's
highly recommended to make a database backup with mysqldump before
the update!
even though we have a major new version with this release the
update is mostly backwards compatible, but please note:
- new runtime dependency opt/libaio
- new buildtime dependency cmake
- ImmoDB is now the default database engine, the supplied
/etc/my.conf still sets MyISAM as the default and skips
InnoDB. Don't reject /etc/my.cnf without inspection.
- after the upgrade fix or rejmerge /etc/my.cnf, start
the server and run mysql_upgrade to adjust the mysql
system database tables.
