| The upshot of this script is that any file which matches /var/log/apache2/*.log is rotated every week, compressed, if it's non-empty. The new file is created with the file mode of 640, and after the rotation has finished the server is restarted.
| |
| | |
| If we wish to install a local service which creates a logfile we can cause it to be rotated very easily, just by adding a new logrotate configuration file.
| |
| | |
|
| |
| | |
| Assuming we have a new service "web" which produces its output in /var/log/web/output.log we can cause this to be rotated every day with a script like this:
| |
| | |
|
| |
| | |
| /var/log/web/*.log {
| |
| | |
| daily
| |
| | |
| missingok
| |
| | |
| rotate 7
| |
| | |
| compress
| |
| | |
| delaycompress
| |
| | |
| create 640 web web
| |
| | |
| sharedscripts
| |
| | |
| /etc/init.d/web restart
| |
| | |
| endscript
| |
| | |
| }
| |
| | |
|
| |
| | |
| This will:
| |
| | |
| * Run daily.
| |
| * Keep no more than 7 days worth of logfiles at any one time.
| |
| * Not complain if there is a logfile missing.
| |
| * Compress the older files, but not yesterdays.
| |
| * Create the new logfiles as being owned by the user and group fred.
| |
| * Restart the service after rotating the logfiles.
| |
| | |
