RE: Logrotate for bind9
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.

Do I need stop bind9 while logs are being rotated? What is the correct

Sorry, but this is not good advice, and I strongly urge everyone not to follow it. Copying a file takes a finite amount of time, so the copy may not have all the latest logs, and those are lost when the original is truncated. The bigger the log file, the higher the chance of losing log messages. The logrotate man page also notes this possibility of losing log messages, and this option should only be used as a last resort, where there's no way to tell a program to reopen its log file. BIND has no such limitation, and so "rndc reconfig" is the right way to handle reopening its log file.

If it finds that the files have been moved (by logrotate) it will create new log files. ...or you use "copytruncate", so the file will be copied and the other stuff (compress, rotate 180, etc..) and then truncated, so BIND has still the same filedescriptors open, but the logfile is rotated :-).
