wget -qO- https://github.com/JasonHe/ddns/raw/main/ddns.sh | bash

After installation, open http://IP:9876 in your browser to complete the configuration.

Save the uninstall script as uninstall-ddns-go.sh, then run:

chmod +x uninstall-ddns-go.sh
sudo ./uninstall-ddns-go.sh

Or use one-command remote uninstall:

wget -qO- https://github.com/JasonHe/ddns/raw/main/uninstall-ddns-go.sh | bash

The uninstall script will:

• stop and disable the ddns-go service
• remove the systemd or OpenRC service file when present
• remove /usr/bin/ddns-go

To search for any remaining related files after uninstall:

find / -name '*ddns-go*' 2>/dev/null

A robust cross-distribution install/upgrade/uninstall script for ddns-go.

This project provides an install/upgrade/uninstall script that:

• fetches the latest ddns-go release from GitHub
• parses release metadata with jq
• detects supported Linux CPU architectures automatically
• supports multiple Linux distributions and package managers
• supports both systemd and OpenRC
• backs up the existing binary before replacement
• attempts rollback automatically if the upgraded service fails to start

• Safe upgrade flow
  • does not delete the old binary before the new one is downloaded and extracted
  • creates a backup before replacing the executable
  • attempts rollback on startup failure
• Release metadata parsing with jq
• Broad Linux distribution support
• Broad CPU architecture support
• Temporary workspace cleanup with mktemp
• Service management support for:
  • systemd
  • OpenRC

• apt
• dnf
• yum
• pacman
• zypper
• apk

This script is designed to match all currently published Linux builds of ddns-go:

• linux_arm64
• linux_armv5
• linux_armv6
• linux_armv7
• linux_i386
• linux_mips64le_hardfloat
• linux_mips64le_softfloat
• linux_mips64_hardfloat
• linux_mips64_softfloat
• linux_mipsle_hardfloat
• linux_mipsle_softfloat
• linux_mips_hardfloat
• linux_mips_softfloat
• linux_riscv64
• linux_x86_64

• systemd
• OpenRC

If no supported init system is detected, the script can still upgrade the binary, but service installation and service restart may need to be handled manually.

• Linux
• root privileges
• internet access to GitHub
• one of the supported package managers listed above

The script installs the following tools automatically when needed:

• curl
• wget
• tar
• jq
• binutils

Save your upgrade script as, for example:

upgrade-ddns-go.sh

chmod +x upgrade-ddns-go.sh

sudo ./upgrade-ddns-go.sh

1. Detects the package manager
2. Installs required dependencies
3. Detects the init system
4. Detects CPU architecture
5. Fetches the latest ddns-go release metadata from GitHub
6. Selects the correct release asset
7. Stops the existing service if present
8. Downloads and extracts the new package
9. Backs up the existing binary
10. Replaces the installed binary
11. Installs or updates the service
12. Restarts the service
13. Verifies service health
14. Rolls back automatically if startup fails

For MIPS and MIPS64 targets, the script tries to distinguish between hardfloat and softfloat by inspecting ELF attributes via readelf.

This is a practical approach, but not guaranteed to be perfect on every custom distribution or toolchain. If you are deploying on uncommon MIPS devices, validate the detected architecture before production use.

The script supports OpenRC service control logic. However, whether ddns-go -s install can install a native OpenRC service depends on ddns-go itself.

If ddns-go does not generate an OpenRC service script on your platform, you may need to create /etc/init.d/ddns-go manually.

Use at your own risk. Although the script includes backup and rollback logic, you should still test it in your own environment before using it on production systems.
