- 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!
Incompatible Change: The shared library version of the client library
was increased to 18 to reflect ABI changes, and avoid compatibility
problems with the client library in MySQL 5.1. Note that this is an
incompatible change between 5.5.10 and earlier 5.5 versions, so client
programs that use the 5.5 client library should be recompiled against
the 5.5.10 client library.
Extract from http://dev.mysql.com/doc/refman/5.5/en/news-5-5-10.html
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.
