DNS problem

I use ispconfig 3 with BIND for all my domains and it works without a problem, so I guess there must be a misconfiguration on your system.

ISPConfig 3 is never writing to named.conf, it writes to a include file that is included at the end of the named.conf file. To work properly, the files must be in the default locations of the linux distribution. For centos these settings are used:

Code:

$conf['bind']['installed'] = false; // will be detected automatically during installation
$conf['bind']['bind_user'] = 'named';
$conf['bind']['bind_group'] = 'named';
$conf['bind']['bind_zonefiles_dir'] = '/var/named/chroot/var/named/';
$conf['bind']['named_conf_path'] = '/var/named/chroot/etc/named.conf';
$conf['bind']['named_conf_local_path'] = '/var/named/chroot/var/named/named.local';
$conf['bind']['init_script'] = 'named';

The ns entrys are all in the file /var/named/chroot/var/named/named.local and this has to be included into the file /var/named/chroot/etc/named.conf.

Detailed installation instructions on how to install ispconfig 3 with bind on cenos can be found in the file INSTALL_CENTOS_5.4_dovecot_bind.txt in the docs directory of the ispconfig tar.gz file. Please check that you have done all the nescessary installation steps incl. tthe creation of named.conf etc.

From the installation manual:

Code:

5) Install bind dns server

yum install bind-chroot

chmod 755 /var/named/
chmod 775 /var/named/chroot/
chmod 775 /var/named/chroot/var/
chmod 775 /var/named/chroot/var/named/
chmod 775 /var/named/chroot/var/run/
chmod 777 /var/named/chroot/var/run/named/
cd /var/named/chroot/var/named/
ln -s ../../ chroot
cp /usr/share/doc/bind-9.3.6/sample/var/named/named.local /var/named/chroot/var/named/named.local
cp /usr/share/doc/bind-9.3.6/sample/var/named/named.root /var/named/chroot/var/named/named.root
touch /var/named/chroot/etc/named.conf

vi /var/named/chroot/etc/named.conf

The file named.conf.local will be created by ispconfig when you add the first zone file.

 

Centos is always a bit tricky to install and you have to compile several pacakges manually. I recommend that you use debian, the setup is much easier and debian is the recommended linux distribution for ispconfig.
