How about a clear, direct example of using external service 'logrotate' (this
is from one of my redhat systems, but the same concept applies to
Ubuntu/Debian):
[be...@dns-nomnom1.den ~]$ cat /etc/logrotate.d/named
/var/log/named/*.log {
compress
create 0644 named named
daily
dateext
missingok
notifempty
rotate 30
sharedscripts
postrotate
/usr/sbin/rndc reconfig > /dev/null 2>/dev/null || true
endscript
}
We put our logs in the custom location of '/var/log/named/'; if you put them
somewhere else, you'll need to change that. The other settings are direct
references to Anand's email. Finally, you'll want to change the 30 to 180 to
keep 180 different days worth of logs.
BIND internally doesn't have the concept based rotation, only size-based
rotation. In order to achieve per-day logs, you'll need to use the external
tool 'logrotate' (or similar) for your rotation. If you do that, you'll want to
disable BIND's rotation in the logs configuration (if you're using that
currently), so not this:
logging {
channel ns_log {
file "/var/log/named/named.log" versions 3 size 256M;
severity dynamic;
print-time yes;
print-severity yes;
print-category yes;
};
...
category default { ns_log; };
category general { ns_log; };
category config { ns_log; };
};
But this:
logging {
channel ns_log {
file "/var/log/named/named.log";
severity dynamic;
print-time yes;
print-severity yes;
print-category yes;
};
...
category default { ns_log; };
category general { ns_log; };
category config { ns_log; };
};
Hope this clarifies the idea a little for you.

Hi There,
I am not getting appropriate results for my custom daily logrorate for bind9
logs on Ubuntu.
Can someone please help me with the settings which would include below stuff
1. Should rotate daily
2. Compress
3. create new file
4. keep last 180 entries
Do I need stop bind9 while logs are being rotated? What is the correct
procedure to start logs in new file?
