好多博客都是复制粘贴，乱七八糟，我自己整理一波。

2. 解决

2.1 VPS开启IPV6

默认的VPS一般都不开启IPV6， 需要手动开启，或者在创建的时候直接就开启

开启后的截图

2.2 启用ShadowSocks Server侦听IPV6

sudo nano /etc/shadowsocks.json

before:

{
 "server":"0.0.0.0",           // IPv4
  ...
}

after

{
 "server":"::",           // IPv4 和 IPv6
  ...
}

2.3 修改HOST

sudo nano /etc/hosts

append 在文末添加

## Scholar For Google
2404:6800:4005:80b::2003 scholar.google.com #来源 https://github.com/lennylxx/ipv6-hosts

IPV6的host来自github，不确认是否还在维护。

最后，sudo reboot，应该就可以了。
