Hello, been trying to optimise mysql via my.cnf but when i make changes i get errors in plesk CP:




old settings

[mysqld]
old_passwords=1
safe-show-database
innodb_data_file_path=ibdata1:10M:autoextend
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock

[mysql.server]
user=mysql
basedir=/var/lib

[safe_mysqld]
err-log=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid






New settings

errors relate to MYI files example from mysql logs


070823 16:17:07 [ERROR] /usr/libexec/mysqld: Can't find file: 'misc.MYI' (errno: 2)

070823 16:17:20 [ERROR] /usr/libexec/mysqld: Can't find file: 'smtp_poplocks.MYI' (errno: 2)



With this plesk CP does not work?

Any ideas?


Cheers

Comment these lines and try restarting the mysql

#innodb_data_file_path=ibdata1:10M:autoextend
#skip-innodb
#basedir=/var/lib

Also you may try this

cd /var/lid/mysql/mysql
myisamchk --silent --force *.MYI

myisamchk --silent --force *.MYI

cheers first option seems to have worked, though not sure if will have any adverse affects?
