1.CentOS官方的Wiki提供了在7上關閉IPv6的方法。英文以下

How do I disable IPv6?

Upstream employee Daniel Walsh recommends not disabling the ipv6 module, as that can cause issues with SELinux and other components, but adding the following to /etc/sysctl.conf:

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
To disable in the running system:

echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6
echo 1 > /proc/sys/net/ipv6/conf/default/disable_ipv6
or

sysctl -w net.ipv6.conf.all.disable_ipv6=1
sysctl -w net.ipv6.conf.default.disable_ipv6=1
Additional note #1: If problems with X forwarding are encountered on systems with IPv6 disabled, edit /etc/ssh/sshd_config and make either of the following changes:

2.在IPv4下ss同時監聽IPv4和IPv6後沒法使用

方法：修改config

刪去"server":["[::0]"]
若是vps只有ipv4地址的話配置文件裏同時監聽ipv4和ipv6會出錯，只能改爲"server":"0.0.0.0"才行
