We strongly encourage you to keep the DNS service BIND (Berkeley Internet Name Domain) updated with the latest version on your Dedicated 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.
exclude=bind-chroot caching-nameserver
Adding this line to the configuration file will prevent yum from ever being able to update these packages. This can causes 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:
Error: Missing Dependency: bind = 31:9.4.2-3.fc7 is needed by package caching-nameserver
or
Error: Missing Dependency: bind = 31:9.4.2-3.fc7 is needed by package bind-chroot
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:
cp /etc/sysconfig/named.bak /etc/sysconfig/named
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.
