some InnoDB settings in My.cnf are messing up everything, why?
Question
When I edit my.cnf in MySQL 5.0 in filemanager and add the following settings, I get logged out automatically from Kloxo and when I remove these line and restart server everything is ok then:
innodb_buffer_pool_size = 50M
innodb_log_file_size = 15M
but when I add the following line and restart I have no problem and this setting has been set:
bulk_insert_buffer_size=25M
Why is this happening?
P.S.:
I should note that Horde_groupware database have innoDB tables, when everything is messed up and I SELECT * FROM Horde_groupware.tblname
I get the error says bad information in .frm file.
Solution
The next time you start mysql successfully, please run these
SHOW VARIABLES LIKE 'innodb_log_file_size';
This will show you the size of the InnoDB Log Files. The names of those files are (by default)
- /var/lib/mysql/ib_logfile0
- /var/lib/mysql/ib_logfile1
In order to change the size of the InnoDB Log Files, you must
- Add
innodb_log_file_size = 15M
to my.cnf service mysql stop
rm -f /var/lib/mysql/ib_logfile*
service mysql start

I wrote about this before : How to safely change MySQL innodb variable 'innodb_log_file_size'?
This will recreate the InnoDB Log Files.
With regard to
I should note that Horde_groupware database have innoDB tables, when everything is messed up and I SELECT * FROM Horde_groupware.tblname I get the error says bad information in .frm file.
If Horde_groupware.tblname
is an InnoDB table and you get this error, run this:
SHOW ENGINES;
You should see all the supported storage engines for the mysql instance. With the erro you are see on that table, there is one of three possiblilities:
- InnoDB is not listed as one of the storage engines
- InnoDB is marked as DISABLED
- The table itself is corrupt
