This is a bit confusing. How can I install it? The common configuration files are all under/etc/. Of course, you can also run rpm-ax | grep I bind to check out/etc/named .*
[Root @ testserver named] # ls-La/etc/named .*
Lrwxrwxrwx 1 root named 52 Dec 17 16:50/etc/named. caching-nameserver.conf->/var/named/chroot/etc/named. caching-nameserver.conf
Lrwxrwxrwx 1 root named 42 Dec 17 16:50/etc/named. rfc1912.zones->/var/named/chroot/etc/named. rfc1912.zones
Have you seen it? It turns out to be an l file. There are two methods. You can directly go to the original directory to edit the original file or operate on the linked file. The effect is the same!
