关于IPV6的访问测试

服务器端操作系统版本centos7.x，有端口为6080的web应用，
原ipv4的是正常的：http://192.168.207.107:6080/arcgis/rest/services,
需测试http://[fe80::6f96:ee53:4e0f:91c8]:6080/arcgis/rest/services可正常访问。

1.本机测试：

需确认是否正常输出页面内容?

[root@arcgisserver ~]# ping6 -c 4 -I ens32 fe80::6f96:ee53:4e0f:91c8

以上测试ping和telnet ipv6端口正常；
以下测试访问地址输出：
[root@arcgisserver ~]# curl -6 -g --interface ens32 "http://[fe80::6f96:ee53:4e0f:91c8]:6080/arcgis/rest/services"

1.1注意curl版本自带的7.29版本太低，必须升级，否则提示错误：

curl: (45) bind failed with errno 22: Invalid argument

升级curl操作步骤：
下载最新版本即可：https://github.com/moparisthebest/static-curl/releases

[root@arcgisserver ~]# mv /usr/bin/curl{,-bak}

1.2其中ens32为本机的ipv6对应的网卡，通过ip a或ifconfig -a可以核查到。

2同网段其它linux主机测试：网卡需指定客户端的网卡名称，意思是从该具有IPV6的网卡去访问目标IPV6地址，可以正常访问

[root@localhost ~]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: ens192: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 00:0c:29:14:92:fb brd ff:ff:ff:ff:ff:ff
    inet 192.168.207.217/24 brd 192.168.207.255 scope global noprefixroute ens192
       valid_lft forever preferred_lft forever
    inet6 fe80::1c0b:f3a8:c952:c9fa/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever
[root@localhost ~]# curl -6 -g --interface ens192 "http://[fe80::6f96:ee53:4e0f:91c8]:6080/arcgis/rest/services"

3同网段windows主机访问测试：访问正常

4同网段其它机器访问失败（需有支持ipv6的交换机）
