5.7 Adding or Removing Zones Without Restarting or Reloading the Name Server
You want to add a new zone or delete
an existing zone without restarting or reloading a name server.
Add a new zone
statement to named.conf or delete an existing
one, then run rndc reconfig (for BIND 9) or
ndc reconfig (for BIND 8).
It's nice to avoid
restarting a busy name server, since restarting clears the cache and
takes time on a name server that is authoritative for many zones. A
reload, while it doesn't clear the cache, can take
time as the name server checks all of its zone data files to see if
they've changed. Using reconfig
avoids these issues, just scanning
named.conf for added or deleted zones.
ndc supports reconfig
as of BIND 8.2.2. At BIND 8.2.3, though, you can also use
ndc reconfig -noexpired, which prevents the name
server from trying to load expired zones.
