one-click-doh

A shell script to install a DNS over HTTPS (DoH) server with Chinese-specific configuration, EDNS support, and cache enabled, using DNS Proxy and dnsmasq-china-list.

Install

wget -q https://raw.githubusercontent.com/funnycups/one-click-doh/main/install.sh && bash install.sh

In theory, it supports CentOS, Fedora, Debian, and Ubuntu.

By default, the script will use Cloudflare and DNS.SB as default upstreams.

To change the default DNS upstreams configuration, please edit /home/dnsproxy/update.sh. To apply changes, either run update.sh manually or wait for it to run automatically within 3 hours.

Uninstall

To remove the installed DoH service and configuration:

bash install.sh --uninstall

What this does:

• Stops and disables the dnsproxy systemd service, removes the unit file.
• Removes the cron job that updates /home/dnsproxy/list.txt.
• Deletes /home/dnsproxy and /usr/bin/dnsproxy.

DNS restore behavior:

• During install, if nameserver 127.0.0.1 is applied, the script first backs up /etc/resolv.conf to /etc/resolv.conf.bak (if not already present).
• During uninstall, it restores /etc/resolv.conf from the backup when available. If no backup exists but resolv.conf points to 127.0.0.1, it falls back to public DNS (Cloudflare 1.1.1.1 and Google 8.8.8.8).
