SAN服务器：
Openfiler 2.3来部署的，在这里分配3个LUN，大小分别为5G和两个8G。

正式部署安装
1、配置DNS服务
以下操作在DNS服务器上进行：
安装bind三个包
[root@dns12c ~]# rpm -ivh /mnt/Server/bind-9.3.6-20.P1.el5.x86_64.rpm
[root@dns12c ~]# rpm -ivh /mnt/Server/bind-chroot-9.3.6-20.P1.el5.x86_64.rpm
[root@dns12c ~]# rpm -ivh /mnt/Server/caching-nameserver-9.3.6-20.P1.el5.x86_64.rpm
配置主区域
[root@dns12c ~]# cd /var/named/chroot/etc
[root@dns12c etc]# cp -p named.caching-nameserver.conf named.conf
[root@dns12c etc]# cat named.conf
options {
? ? ? ? listen-on port 53 { any; };
? ? ? ? listen-on-v6 port 53 { ::1; };
? ? ? ? directory? ? ? "/var/named";
? ? ? ? dump-file? ? ? "/var/named/data/cache_dump.db";
? ? ? ? statistics-file "/var/named/data/named_stats.txt";
? ? ? ? memstatistics-file "/var/named/data/named_mem_stats.txt";
? ? ? ? // Those options should be used carefully because they disable port
? ? ? ? // randomization
? ? ? ? // query-source? ? port 53;
? ? ? ? // query-source-v6 port 53;
?
nslookup或 dig检查
?
给两个节点配置DNS
(以Node1为例，两个节点相同)
[root@12crac1 ~]# cat /etc/resolv.conf
#domain localdomain
search localdomain
nameserver 192.168.1.158
?
测试：
[root@12crac1 ~]# nslookup 192.168.1.154
Server:? ? ? ? 192.168.1.158
Address:? ? ? ? 192.168.1.158#53
[root@12crac1 ~]# nslookup 192.168.1.155
Server:? ? ? ? 192.168.1.158
Address:? ? ? ? 192.168.1.158#53
[root@12crac1 ~]# nslookup 192.168.1.156
Server:? ? ? ? 192.168.1.158
Address:? ? ? ? 192.168.1.158#53
?
2、配置/etc/hosts
修改/etc/hosts文件，前两行不懂，添加hostname对应信息。
(以Node1为例，两个节点相同)
[root@12crac1 ~]# cat /etc/hosts
127.0.0.1? localhost localhost.localdomain localhost4 localhost4.localdomain4
::1? ? ? ? localhost localhost.localdomain localhost6 localhost6.localdomain6
