MySQL won't create a slow query log

2 New Member
Posted by Pratchaya:
In my.cnf

i add these lines

log-slow-queries = /var/log/mysqld-slow.log
long_query_time =1

But I can't use slow-log
cause i see mysqld.log
i found

070211 20:04:25 mysqld started
^G/usr/libexec/mysqld: File '/var/log/mysqld-slow.log' not found
(Errcode: 13)
070211 20:04:25 [ERROR] Could not use /var/log/mysqld-slow.log for
logging (error 13). Turning logging off for the whole duration of the
MySQL server process. To turn it on again: fix the cause, shutdown the
MySQL server and restart it.
/usr/libexec/mysqld: ready for connections.
Version: '4.1.20-log' socket: '/var/lib/mysql/mysql.sock' port: 0
Source distribution

but in the directory /var/log i have "mysqld-slow.log" file

Thank you very much

I had the same error about slow queries logging file. Maybe it is a bug with resolving
filepath string of log-slow-queries variable, because setting the value just to a file
name solved the problem.
log-slow-queries = /var/log/mysql.slow.log # Does not work!
log-slow-queries = mysql.slow.log # Works! MySQL takes it from {datadir} directory

Heya, mezise. Welcome to TSDN!

Changed thread title to better describe the problem (did you know that threads whose titles do not follow the Posting Guidelines actually get FEWER responses?).

Make sure the file exists before starting mysqld. For some reason, mysqld doesn't seem to want to create the log files if they don't exist (the exception might be when saving in the data dir).

Hi everyone. I was faced with the choice of whether my problem is indeed a PHP problem or a MySQL. I have decided it's a PHP problem as I don't experience the same problem when I execute the same query at the CLI. I am having trouble executing a large query through my PHP script. It takes about 7-11 seconds on average to execute, whereas the same query only takes 0.01 seconds to execute through the CLI.
