Update BIND on Your Linux Dedicated/Virtual Dedicated Server
We strongly encourage you to keep the DNS service BIND (Berkeley Internet Name Domain) updated with the latest version on your Dedicated Server.
Note to Red Hat 9 Customers If you are running a Virtual Dedicated server with the Red hat 9 operating system, you will need to either upgrade to a more current operating system or download the source RPM from the BIND Web site for your version of BIND and compile it on your server.
To Update BIND
- SSH to your server.
- Type
su -
and press Enter to gain root access. - Type
cp /etc/sysconfig/named /etc/sysconfig/named.bak
- Type
yum clean all
. - Type
yum update bind
.
The system will then proceed to update all the needed packages for you automatically.
If you are running a server with Plesk there are certain packages that can be installed that will interfere with Plesk's functionality. If you have not already, please add the following line to your /etc/yum.conf to ensure that YUM does not update any packages that may break Plesk.
Adding this line to the configuration file will prevent yum from ever being able to update these packages. This can cause issues in the future should you want to use yum to update anything listed as an exclude.
If you have never made any changes to your yum.conf file you can use the following procedure to make this update:
- SSH to your server.
- Type su - and press Enter to gain root access.
- Type
echo "exclude=bind-chroot caching-nameserver" >> /etc/yum.conf
Once this is complete you can run the yum update statements at the top of the article. If you receive an error similar to the following:
or
You may need to remove bind-chroot and/or caching-nameserver from your server prior to upgrading. To do this you can do the following:
- SSH to your server.
- Type
su -
and press Enter to gain root access. - Type
yum -y remove bind-chroot caching-nameserver
.
The removal of these packages can cause adverse effects on your server. You may need to restore the version of /etc/sysconfig/named that you backed up by using the following command:
NOTE: This will install the most up to date version of BIND on your server. As the server administrator it will be your responsibility to determine whether or not a version update will cause any conflicts on your server. It is your responsibility to troubleshoot any issues that arise from performing this update.
