配置完bind，在其他主机进行域名解析的时候出现如下问题：

[root@Rac-one named]# nslookup rhel-cluster-scan.grid.example.com
;; connection timed out; trying next origin
;; connection timed out; no servers could be reached

问题解决：

修改bind服务器named.conf配置

修改之前：

options {
        listen-on port 53 { 127.0.0.1; };
        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";
        allow-query     { localhost; };
        recursion yes;

修改之后：

options {
        listen-on port 53 { 192.168.4.102; };
        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";
        allow-query     { any; };
        recursion yes;

进行验证：

[root@Rac-two devices]# nslookup rhel-cluster-scan.grid.example.com
Server: 192.168.4.102
Address: 192.168.4.102#53

Name:   rhel-cluster-scan.grid.example.com
Address: 192.168.4.150
Name:   rhel-cluster-scan.grid.example.com
Address: 192.168.4.151
Name:   rhel-cluster-scan.grid.example.com
Address: 192.168.4.149

[root@Rac-two devices]#
