У меня проблемы со скриптом prerotate в logrotate 3.12.2. Скрипт я указываю в prerotate/endscript секция не получает имя файла для поворота в качестве первого аргумента ($1).
Вот конфигурация logrotate:
compress
/external-logs/syslog {
daily
rotate 3
olddir OLD
missingok
prerotate
/root/filter-syslog.sh
endscript
}
Вот это /root/filter-syslog.sh:
#!/bin/sh
echo "log file subject to prerotate: $1"
Наконец, вот подробный вывод выполнения logrotate:
reading config file /external-config/logrotate.conf
olddir is now OLD
Reading state from file: /external-logs/logrotate.state
Allocating hash table for state file, size 64 entries
Creating new state
Handling 1 logs
rotating pattern: /external-logs/syslog after 1 days (3 rotations)
olddir is OLD, empty log files are rotated, old logs are removed
considering log /external-logs/syslog
Now: 2017-09-24 13:35
Last rotated at 2017-09-23 12:50
log needs rotating
rotating log /external-logs/syslog, log->rotateCount is 3
dateext suffix '-20170924'
glob pattern '-[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]'
renaming /external-logs/OLD/syslog.3.gz to /external-logs/OLD/syslog.4.gz (rotatecount 3, logstart 1, i 3),
old log /external-logs/OLD/syslog.3.gz does not exist
renaming /external-logs/OLD/syslog.2.gz to /external-logs/OLD/syslog.3.gz (rotatecount 3, logstart 1, i 2),
old log /external-logs/OLD/syslog.2.gz does not exist
renaming /external-logs/OLD/syslog.1.gz to /external-logs/OLD/syslog.2.gz (rotatecount 3, logstart 1, i 1),
old log /external-logs/OLD/syslog.1.gz does not exist
renaming /external-logs/OLD/syslog.0.gz to /external-logs/OLD/syslog.1.gz (rotatecount 3, logstart 1, i 0),
old log /external-logs/OLD/syslog.0.gz does not exist
log /external-logs/OLD/syslog.4.gz doesn't exist -- won't try to dispose of it
running prerotate script
log file subject to prerotate:
renaming /external-logs/syslog to /external-logs/OLD/syslog.1
compressing log with: /bin/gzip
Обратите внимание на строку "log file subject to prerotate:"в приведенном выше выводе. Почему не выводится строка"log file subject to prerotate: /external-logs/syslog"вместо этого?
Вы ничего не передаете своему сценарию оболочки. Так $1 в твоем /root/filter-syslog.sh не имеет значения и поэтому ничего не печатается.
echo "log file subject to prerotate: $1"
Чтобы это сработало, нужно пройти $1 или $@ в вашей конфигурации logrotate.
compress
/external-logs/syslog {
daily
rotate 9
olddir OLD
missingok
prerotate
/root/filter-syslog.sh $1
endscript
}
