| | # example logrotate config file, I usually keep this in
# /etc/logrotate.d/unicorn_app on my Debian systems

# public logrotate-related discussion in our archives:

# Modify the following glob to match the logfiles your app writes to:
/var/log/unicorn_app/*.log {
# this first block is mostly just personal preference, though
# I wish logrotate offered an "hourly" option...
daily

rotate 180
compress # must use with delaycompress below
dateext
# this is important if using "compress" since we need to call
# the "lastaction" script below before compressing:
delaycompress
# note the lack of the evil "copytruncate" option in this
# config. Unicorn supports the USR1 signal and we send it
# as our "lastaction" action:
lastaction
# For systemd users, assuming you use two services
# (as recommended) to allow zero-downtime upgrades.
# Only one service needs to be started, but signaling
# both here is harmless as long as they're both enabled
systemctl kill -s SIGUSR1 unicorn@1.service
systemctl kill -s SIGUSR1 unicorn@2.service
# Examples for other process management systems appreciated
# Mail us at unicorn-public@bogomips.org
# (see above for archives)
# If you use a pid file and assuming your pid file
# is in /var/run/unicorn_app/pid
pid=/var/run/unicorn_app/pid
test -s $pid && kill -USR1 "$(cat $pid)"
