Squid Log file Rotation with logrotate

I.  Install the lotrotate from ports
cd /usr/ports/sysutils/logrotate
make install clean


II Create a new logrotate.conf file.

vi /usr/local/etc/logrotate.conf

# Added the following to rotate Apache and Squid logs

# see “man logrotate” for details
# rotate log files weekly
#weekly
daily

# keep 4 weeks worth of backlogs
rotate 7

# send errors to root
#errors root

# create new (empty) log files after rotating old ones
create

# uncomment this if you want your log files compressed
compress

# RPM packages drop log rotation information into this directory
include /usr/local/etc/logrotate.d

/var/log/lastlog {
monthly
rotate 12
}

# system-specific logs may be configured here

III Create a directory for specific logrotate files

mkdir -p /usr/local/etc/logrotate.d

VI. First, create a logrotate file for Squid to rotate it’s access.log files for 90 days and cache.log for 7 days.

cd /usr/local/etc/logrotate.d/

vi /usr/local/etc/logrotate.d/squid

#Copy and paste the following

/var/log/squid/access.log {
daily
rotate 90
copytruncate
compress
notifempty
missingok
}
/var/log/squid/cache.log {
daily
rotate 7
copytruncate
compress
notifempty
missingok
}

V. Create the necessary directories and files for logrotate and test and debug logrotate

mkdir /var/lib/

touch /var/lib/logrotate.status

/usr/local/sbin/logrotate -d /usr/local/etc/logrotate.conf
/usr/local/sbin/logrotate -f /usr/local/etc/logrotate.conf

VI. Next, we will rotate and manage Apache logs

vi /usr/local/etc/logrotate.d/apache

#Add the following to rotate and manage Apache access_log and error_log for 30 days.

#Note: If your Apache logs may be in a different directory, simply change the directory.

/var/log/apache/access_log {
daily
rotate 30
copytruncate
compress
notifempty
missingok
}
/var/log/apache/error_log {
daily
rotate 30
copytruncate
compress
notifempty
missingok
}

If all goes well, that’s it. Your Apache and Squid logs should be rotated.

The last thing is to add an entry into crontab and letting the cron daemon rotate your Apache and Squid logs automatically.

VII.  Automating logrotate using crontab

vi /etc/crontab

#Add the following to rotate your logs at 1 AM in the morning

#Logrotate
0 1 * * * root /usr/local/sbin/logrotate /usr/local/etc/logrotate.conf > /dev/null 2>&1

That’s it. Your Apache and Squid logs will be rotating without manual intervention!!
