Nginx with IPv6

Nginx开启IPV6支持配置

查看nginx是否支持ipv6

[root@CentOS7-1 ~]# nginx -V

nginx version: nginx/1.16.1

built by gcc 4.8.5 20150623 (Red Hat 4.8.5-39) (GCC)

built with OpenSSL 1.0.2k-fips 26 Jan 2017

TLS SNI support enabled

同时监听IPV4和IPV6

server {
....
listen 80;
listen [::]:80;
...
}

 

如果开启了 ssl 和 http2 ，可以改成：

listen 443 ssl http2;
listen [::]:443 ssl http2;

 

只监听IPV6

server {
....
listen [::]:80 default ipv6only=on;
...
}

 

监听指定IPV6地址

server {
....
listen [3608:f0f0:3002:31::1]:80;
...
}

 

修改完成后，必须重启nginx服务（reload是不行的）：

service nginx restart

 

测试时，如果没有AAAA的解析，可以写本地host进行测试，例：

2604:180::728f:8d23 www.wlsun.com
2604:180::728f:8d23 wlsun.com

 

相关防火墙配置：

ip6tables -I INPUT -p tcp --dport 80 -j ACCEPT
service ip6tables save

 

Nginx反向代理IPv6配置

IPv4/IPv6双栈支持，nginx反向代理配置如下：

upstream sa{

    server 172.16.0.216:8080;   #SA Server1
    server 172.16.0.232:8080;   #SA Server2
}
upstream sa_ipv6{
    server [2001:470:fb3c:0:f816:3eff:fed0:2ae2]:8080;   #SA Server1
    server [2001:470:fb3c:0:f816:3eff:fe68:27b3]:8080;   #SA Server2
}


server {
    listen       80;  ## listen for ipv4
    server_name  localhost;


    location / {
        #index index.html;
        proxy_set_header Host $host:$server_port;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header REMOTE-HOST $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass   http://sa;
    }
}
server {
    listen [::]:80 ipv6only=on;  ## listen for ipv6
    server_name  localhost;


    location / {
        #index index.html;
        proxy_set_header Host $host:$server_port;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header REMOTE-HOST $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass   http://sa_ipv6;
    }
}

*ipv4和ipv6可以互相反向代理。
