本文通过 ddns-go(github 关注数 10K+)项目,将动态公网 IPv4 或 IPv6 地址自动绑定到由域名服务商管理的域名,其实现原理: 首先获取本地动态公网 IP 地址,然后通过域名服务商的 API 来管理 DNS 解析记录
ddns-go 支持的域名服务商: 阿里云、腾讯云、Dnspod、Cloudflare、华为云、Callback、百度云、Porkbun、GoDaddy、Namecheap、NameSilo、Dynadot
本文以 NameSilo 为例,具体步骤如下
环境介绍
1》Rocky Linux release 8.9 (kernel 4.18.0)
2》ddns-go v6.6.3
安装、配置 ddns-go
1、下载解压,获取可运行二进制文件 ddns-go
wget https://github.com/jeessy2/ddns-go/releases/download/v6.6.3/ddns-go_6.6.3_linux_x86_64.tar.gz tar xf ddns-go_6.6.3_linux_x86_64.tar.gz mv ddns-go /usr/local/bin/ mkdir /etc/ddns-go
2、创建 ddns-go 配置文件
默认配置文件保存路径:/root/.ddns_go_config.yaml ,该配置文件内容可手动编辑,或通过 web 管理
cat /etc/ddns-go/ddns_go_config.yaml dnsconf: - name: "" # ipv4 公网 IP 与 DNS 配置 ipv4: enable: true gettype: url # 通过如下配置的 url 获取公网 IPv4 地址 url: https://myip.ipip.net, https://ddns.oray.com/checkip, https://ip.3322.net, https://4.ipw.cn netinterface: ens3 cmd: "" domains: - "" ipv6: enable: true gettype: netInterface # 通过本机网卡 ppp0 获取公网 IPv6 地址 url: https://speed.neu6.edu.cn/getIP.php, https://v6.ident.me, https://6.ipw.cn netinterface: ppp0 cmd: "" ipv6reg: "" domains: # 通过 DNS 服务商 API 更新域名(demo.jiawen.com)解析到上面获取的 IPv6 地址 - demo.jiawen.com dns: # 设置域名 jiawen.com 托管的 dns 服务商为 namesilo name: namesilo id: "" # namesilo api key 获取地址 https://www.namesilo.com/account/api-manager secret: 24fbafc28671f73aed1f ttl: "" user: # ddns-go web 管理账号 username: admin password: $2a$10$FfGa/rE0BXMcYBhLSjUPcOOcNpCODc3ZesFoXNR/a/FQhA73FHumW webhook: webhookurl: "" webhookrequestbody: "" webhookheaders: "" notallowwanaccess: true lang: zh
运行 ddns-go
1、手动运行 ddns-go
# 运行 ddns-go ,可通过选项 -noweb 禁用 web 管理 /usr/local/bin/ddns-go -l 0.0.0.0:9876 -f 300 -cacheTimes 5 -c /etc/ddns-go/ddns_go_config.yaml #> 2024/07/14 05:25:10 监听 0.0.0.0:9876 #> 请手动打开浏览器并访问 http://127.0.0.1:9876 进行配置 #> 2024/07/14 05:25:14 "Remote: 192.168.31.2:40776" 登陆成功 #> 2024/07/14 05:26:18 配置文件已保存在: /etc/ddns-go/ddns_go_config.yaml #> 2024/07/14 05:26:20 新增域名解析 demo.jiawen.com 成功! IP: 240e:891:ba21:1df5:2d0e:d489:d26b:4245 #> 2024/07/14 05:30:10 IPv6未改变, 将等待 5 次后与DNS服务商进行比对 #> ...
2、基于 systemd 运行 ddns-go(可选)
systemctl cat ddns-go.service # /etc/systemd/system/ddns-go.service [Unit] Description=DDNS-Go Service After=network.target [Service] Type=simple ExecStart=/usr/local/bin/ddns-go -l 0.0.0.0:9876 -f 300 -cacheTimes 5 -c /etc/ddns-go/ddns_go_config.yaml Restart=always [Install] WantedBy=multi-user.target
3、web 管理 http://127.0.0.1:9876 账号 admin admin@123
选择域名服务商、配置其 API key
配置 IPv6 地址获取方式,及其解析到哪个域名。如何获取公网 IPv6 地址,请参考文章:使用 NetworkManager 快速实现 PPPOE 获取公网 IPv6 地址
