Managing Logs

Use logrotate and crontab to manage logs.

Logrotate is a common log management program on Linux, and crontab is a time-based task management system.

/etc/logrotate_sdslog.conf is a log file management parameter of EC Turbo. This file is installed in the specified directory when EC Turbo is installed. It has the following content:

/var/log/ceph/kpsec*.log {
    rotate 30
    daily
    compress
    dateext
    dateformat.%Y%m%d.%s
    size=100M
    missingok
    su ceph ceph
    lastaction
        /usr/bin/chmod 440 /var/log/ceph/kpsec*.gz
        /usr/bin/chmod 440 /var/log/ceph/kpsec*.log-*
        /usr/bin/chmod 440 /var/log/ceph/kpsec*.log.*
    endscript
}

/var/log/sdslog*.log {
    rotate 30
    daily
    compress
    dateext
    dateformat.%Y%m%d.%s
    size=100M
    missingok
    su ceph ceph
    lastaction
        /usr/bin/chmod 440 /var/log/sdslog*.gz
        /usr/bin/chmod 440 /var/log/sdslog*.log-*
        /usr/bin/chmod 440 /var/log/sdslog*.log.*
    endscript
}

Crontab can run a specified task at a fixed time, on a fixed date, or at a fixed interval. Add a task to crontab for logrotate to be executed every minute. Perform the following operations on the kps-sdslog installation package:

Add the cron_sdslog file to /etc/cron.d/. It has the following content:
```
*/1 * * * * root /usr/sbin/logrotate /etc/logrotate_sdslog.conf
```
Change the permission on cron_sdslog file to 600.
