Rhel6 cache DNS configuration Summary

Install the Bind package:

Yum install bind-utils bind-chroot

Edit the configuration file:

Tips

1. The configuration file must belong to the named group.

2. if you simply configure the cache DNS, you 'd better note the green part, when forwarders points to my own DNS server or 8.8.8.8, it cannot be resolved (pointing to 202.96.209.133 and parsing ).

3. After service named restart, check whether the error is returned by sticking to/var/log/message.

4. Modify the nameserver address of/etc/resolv. conf during testing.
