我能够在mongodb上启用ipv6。
/etc/mongod.conf file has net.ipv6 set to true.
我可以看到mongodb在监听ipv6：
# netstat -anp | grep 27017
tcp 0 0 0.0.0.0:27017 0.0.0.0:* LISTEN 17967/mongod
tcp6 0 0 :::27017 :::* LISTEN 17967/mongod
unix 2 [ ACC ] STREAM LISTENING 19750206 17967/mongod /tmp/mongodb-27017.sock
#
ping6到IPv6地址没问题。
[root@tesla05 log]# ping6 -I eno33554952 tesla05-2-ipv6.ulticom.com
PING tesla05-2-ipv6.ulticom.com(tesla05) from fe80::250:56ff:feb4:7c43 eno33554952: 56 data bytes

64 bytes from tesla05: icmp_seq=2 ttl=64 time=0.093 ms
64 bytes from tesla05: icmp_seq=3 ttl=64 time=0.091 ms
但是，mongo shell似乎不了解ipv6地址。

答案 0 :(得分：3)
您正在尝试使用链接本地IPv6地址。如果没有范围，这些无效，但您没有提供。因此，您收到错误Invalid argument。因此，在DNS中放置链接本地地址是没有意义的，因为该地址仅在特定LAN上有效，并且该LAN上的每个主机的范围可能不同。
要使用该地址，请将范围附加到该地址，例如fe80::250:56ff:feb4:7c43%eno33554952
