To configure log rotation:
-
Log in as root or use sudo to execute the following commands.
-
Create a file called zendserver using a text editor and save it in /etc/logrotate.d/, with the following content:
/usr/local/zend/var/log/*.log {
size 5M
missingok
rotate 10
compress
delaycompress
copytruncate
}
-
Save the file.
You have now created a configuration file for all the files located in /usr/local/zend/var/log/ that will be picked-up by logrotate. According to the above mentioned configuration, logrotate checks the file size of each log, every time it is executed (through a daily cron job on most systems). If the file size exceeds 5Mb, the log file is archived by moving the content to a new file and truncating the log file. The new file's name is the same name with an additional number added to the file name. According to the example, logrotate created up to ten backup files. After exceeding ten files, the oldest file is deleted and replaced with new content.
The code example describes the following settings:
- size 5M = file size to rotate
- missingok = if the file is not found, do not generate an error.
- rotate 10 = keep up to ten backup files.
- compress = compress archive log files, using gzip.
- delaycompress = do not compress the newest file created.
- copytruncate = rotation method. In this case, copy the content to a new file and truncate the active log.
