[FIXED] bind9 is running bind9 status reports failed!

bind9 runs in a chroot environment on lenny. The service can be started as usual:


# /etc/init.d/bind9 start
Starting domain name service...: bind9.

Let’s check bind9 status:

# /etc/init.d/bind9 status
bind9 is not running failed!

Well, the first thing I did was to check the log file, in which I found no error related to named. So I tried another way to check the status:

# rndc status
version: 9.6-ESV-R3
CPUs found: 1
worker threads: 1
number of zones: 17
debug level: 0
xfers running: 0
xfers deferred: 0
soa queries in progress: 0
query logging is OFF
recursive clients: 0/0/1000
tcp clients: 0/100
server is up and running

I was convinced that dns service was running. So what went wrong? It must be something in the /etc/init.d/bind9 script that incorrectly reports bind9 status. Opened up this file, I found:

...
PIDFILE=/var/run/bind/run/named.pid
...

Ah ha, the default location of named.pid is in /var/run/bind/run. In my case, named.pid is located in /var/chroot/var/run/bind/run/named.pid. Therefore in order to fix this, we just need to point PIDFILE to the correct file.

PIDFILE=/var/chroot/var/run/bind/run/named.pid

Save bind9 script, and check bind9 status again:

# /etc/init.d/bind9 status
bind9 is running.
