logrotate

slow-queries.logのlogrotateがしたい。

{mysqlのsrc}/upport-files/mysql-log-rotate
を参考にすると良い。
ちなみに中身は

# This logname can be set in /etc/my.cnf
# by setting the variable "err-log"
# in the [safe_mysqld] section as follows:
#
# [safe_mysqld]
# err-log=/usr/local/mysql/var/mysqld.log
#
# If the root user has a password you have to create a
# /root/.my.cnf configuration file with the following
# content:
#
# [mysqladmin]
# password = <secret>
# user= root
#
# where "<secret>" is the password.
#
# ATTENTION: This /root/.my.cnf should be readable ONLY
# for root !

/usr/local/mysql/var/mysqld.log {
        # create 600 mysql mysql
        notifempty
        daily
        rotate 3
        missingok
        compress
    postrotate
        # just if mysqld is really running
        if test -x /usr/local/mysql/bin/mysqladmin && \
           /usr/local/mysql/bin/mysqladmin ping &>/dev/null
        then
           /usr/local/mysql/bin/mysqladmin flush-logs
        fi
    endscript
}

mysqladminにはパスワードをかけていたので、my.cnfに

[mysqladmin]
password = <secret>
user= root

を追加しておく必要がある
