bind支持ipv6

环境

Centos5.8
bind-9.3.6-25.P1.el5_11.12

过程说明

1. 服务器开启ipv6服务
   1. 网卡配置ipv6地址(当前机器都有配置)
   2. 网卡开启ipv6服务

   [root@localhost ~]# cat /etc/sysconfig/network
   NETWORKING=yes
   NETWORKING_IPV6=yes
   HOSTNAME=localhost.localdomain 
   

   如果NETWORKING_IPV6=no,需要修改为yes，然后重启服务器
2. bind开启ipv6服务
   vi /etc/named.conf

   options {
       listen-on port 53 { 127.0.0.1; };
       listen-on-v6 port 53 { ::1; }; ##ipv6
       directory   "/var/named/";
       dump-file   "/var/named/data/cache_dump.db";
       statistics-file "/var/named/data/named_stats.txt";
   };
   
   view localhost_resolver {
       match-clients      { localhost; };
       match-destinations { localhost; };
       recursion yes;
       zone "aa.com" IN {
           type master;
           file "aa.com.zone";
           allow-update { none; };
       };
   };
   

3.配置zone文件
vi /var/named/aa.com.zone内容如下：

$TTL    5
@       IN SOA  @       root (
                                    1997022700 ; Serial
                                    8      ; Refresh
                                    16     ; Retry
                                    24    ; Expire
                                    36 )    ; Minimum
@           IN NS       aaa.
aaa         IN AAAA        0:0:0:0:0:0:0:1

4.启动bind服务

[root@localhost ~]# service named restart 
Stopping named:                                            [  OK  ]
Starting named:                                            [  OK  ]

5.查看dns解析结果

[root@localhost ~]# dig aaa.aa.com AAAA @127.0.0.1 +short
::1

注意点

1. zone文件配置ipv6，是'IN AAAA'；配置ipv4，是'IN A'。
2. 在配置有ipv6的情况下，使用AAAA的选项查询主机的ipv6 AAAA记录，即dig命令添加AAAA选项。

验证结果
nginx配置：

http {
    upstream myserver.com {
        server aaa.aa.com:8001;
    }

    server {
        listen [::]:8080;
        server_name aaa.aa.com;
        resolver 127.0.0.1;
    
        location / {
            proxy_pass http://myserver.com;
        }
    }

    server {
        listen [::]:8001;
        server_name localhost;

        location / {
            return 200 '$server_addr';
        }
    }
}

步骤：
1.启动上述配置的bind服务器和nginx
2.curl -v -x 127.1:8080 http://aaa.aa.com/index.html，响应内容为"::1"

[root@localhost ~]# curl -v -x 127.1:8080 http://aaa.aa.com/index.html
