CURL 不起作用，但 ping 和 nslookup 可以与本地 DNS 服务器 Ubuntu16.04 一起使用

  • 772

我们正在 Ubuntu 16.04 上使用 Bind 服务器。
我们无法curl，因为 DNS 解析但ping和nslookup正在从 Ubuntu16.04 客户端运行。

客户 - ping：

root@app-01:~# ping -c1 nightly.dev.project
PING nightly.dev.project (10.110.2.1) 56(84) bytes of data.
64 bytes from 10.110.2.1: icmp_seq=1 ttl=64 time=1.03 ms

--- nightly.dev.project ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 1.036/1.036/1.036/0.000 ms

客户 - nslookup：

root@app-01:~# nslookup nightly.dev.project
Server:     10.110.1.3
Address:    10.110.1.3#53

Name:   nightly.dev.project
Address: 10.110.2.1

客户 - curl：

root@app-01:~# curl -kv nightly.dev.project

客户 - /etc/resolvconf/resolv.conf.d/head：

nameserver 10.110.1.3
nameserver 10.110.1.2
search dev.project

客户 - /etc/nsswitch：

#hosts:          files mdns4_minimal [NOTFOUND=return] dns
hosts:          dns files
networks:       files

绑定服务器 - /etc/bind/named.conf.options：

options {
    #dnssec-validation auto;
    dnssec-validation no;
    dnssec-enable no;
    allow-recursion { any; };
    allow-recursion-on { any; };
    allow-query { any; };

    auth-nxdomain no;    # conform to RFC1035
    listen-on-v6 { any; };
};
dns url bind curl

    事实证明，代理 -proxy.dev.com无法解析 DNS 记录。
    希望这个答案对遇到这种独特情况的人有所帮助 - 所有客户端配置和 DNS 机器都是正确的，但代理不正确。
