Upgrading BIND to 9.x

Obtain the latest source from the Internet Software Consortium (9.1.1 at the time this page was created).

Backup your current configuration: daemon, startup script, all domain, and conf files.

   suse:~ #cp -r /var/named /var/named.old 
   suse:~ #cp /etc/named.conf /etc/named.old
   suse:~ #cp /usr/sbin/named /usr/sbin/named.old
   suse:~ #cp /etc/rc.d/named /etc/rc.d/named.old

Decompress and untar the source file.

   suse:~/bind #gzip -cd bind-9.1.1.tar.gz | tar xvf -

Change to the newly created bind-9.1.1 {source} directory and compile the source

   suse:~/bind #cd bind-9.1.1
   suse:~/bind/bind-9.1.1 #./configure
   suse:~/bind/bind-9.1.1 #make

Read the README file while it compiles.
Install the source. The default location is /usr/local, but can be changed with --prefix={destination}
```
   suse:~/bind/bind-9.1.1 #make install
```

Default locations of BIND items:

BIND 9 Object	Default Location
named daemon	/usr/local/sbin
system binaries for BIND	/usr/local/sbin
user binaries (nslookup, dig, etc)	/usr/local/bin
man pages of BIND 9	{source}/doc/man
conf file	/etc/named.conf
PID file	/var/run/named.pid

Read the man page for BIND 9

 suse:~ #less {source}/doc/man/bin/named.8

Kill the named daemon if it is runnung
```
   suse:~ #kill -9 /var/run/named.pid
```
Edit your script (/etc/rc.d/named) to start BIND:
If you already had BIND 8 running on your server, you can use the same script by changing the location of the old named daemon to the new one ( default location is /usr/local/sbin/named ). The daemon should be started every time the system starts and enters into the correct run level which supports full networking support (run level 2 or 3 depending on your distribution of Linux). To get named to start at the correct runlevel, you will need to place a script in the /etc/rc.d directory and place a symbolic link ( ln -s /etc/rc.d/named S10named ) to it in the correct rc#.d directory (the # will be the runlevel with full network support ). You will need to make the script /etc/rc.d/named executable ( chmod 744 named ). Try using this script if you don't already have one.
You can then either restart your system or start named using the above script
Restart system:
```
   suse:~ #shutdown -r now
```
Start named using script:
```
   suse:~ #/etc/rc.d/named start
```
If all went well, named should start; you can verify named is running by viewing the PID using the command:
```
   suse:~ #ps aux | grep named 
```
You can use most of the configuration option of BIND 8 with BIND 9, to see which ones are implemented view the options file in {source}/doc/misc/options. Also look at the migration file in the same directory.
