Notes for BIND in LINUX-Linux Enterprise Application-Linux server application information. For details, refer to the following section. BIND default settings
/Etc/named. conf -- set the file
/Etc/sysconfig/named -- whether to start chroot and additional parameters, which are controlled by this file
/Var/named/-- the database file is stored in this directory by default.
/Var/run/named -- named. pid-file is placed in this directory by default when the program is executed.
You can view the directory specified by chroot by viewing/etc/sysconfig/named.
# Vi/etc/sysconfig/named
ROOTDIR =/var/named/chroot
In this way, all the information required by the bind program will be:
/Var/named/chroot/etc/named. conf
/Var/named/chroot/var/named/zone_file1
/Var/named/chroot/var/named/zone_file ......
/Var/named/chroot/var/run/named /......
However, you can still use/etc/named. conf to set your DNS
Because the system will actively help you link/var/named/chroot/etc/named. conf to/etc/named. conf
DNS server summary:
A> the main configuration file is/etc/named. conf.
B> Each positive and reverse solutions require an archive, and the archive file name is set by/etc/named. conf.
C> the current BIND program has been chroot. For details, refer to/etc/sysconfig/named.
D> if no database exists during DNS query, go to the root (.) or forwarders host for query.
E> setting up a DNS server requires authorization from the upper-layer DNS to become a valid DNS server. Otherwise, it can only be internal
F> check the information in/var/log/messages if the named is successfully started.
