2. Upload to OpenWrt's /tmp directory
3. Install:

# IPK package (OpenWrt 22.03.x)
opkg install /tmp/luci-app-easytier_*.ipk

# APK package (OpenWrt SNAPSHOT)
apk add --allow-untrusted /tmp/luci-app-easytier_*.apk

4. Refresh your browser or re-login to LuCI interface
5. Upload EasyTier binary in VPN → EasyTier

Method 2: GitHub Actions Auto-build

1. Fork this repository
2. Modify the architecture list in .github/workflows/build.yml (optional)
3. Go to Actions page and manually trigger the Build-OpenWrt-EasyTier workflow
4. Enter version number (e.g., v1.0.0) and release notes
5. Wait for compilation to complete and download from Releases

Method 3: Local Compilation

# 1. Download OpenWrt SDK
wget https://downloads.openwrt.org/releases/22.03.7/targets/rockchip/armv8/openwrt-sdk-22.03.7-rockchip-armv8_gcc-11.2.0_musl.Linux-x86_64.tar.xz
tar -xJf openwrt-sdk-*.tar.xz
cd openwrt-sdk-*/

# 2. Clone the repository
git clone https://github.com/EasyTier/luci-app-easytier.git package/luci-app-easytier

# 3. Update feeds and configure
./scripts/feeds update -a
./scripts/feeds install -a
make defconfig

# 4. Compile
make package/luci-app-easytier/compile V=s

# 5. Find the generated ipk
find bin/ -name "luci-app-easytier*.ipk"

📦 Dependencies

• kmod-tun - TUN/TAP kernel module (required)
• luci-compat - LuCI compatibility layer

Ensure kmod-tun is installed before installation:

opkg update
opkg install kmod-tun

🔧 Usage

Initial Configuration

1. After installing the plugin, navigate to VPN → EasyTier
2. Upload EasyTier binary files on the Upload Program page, or directly install the ipk/apk package containing the core (easytier.ipk / easytier.apk)
   • Supports single files: easytier-core, easytier-cli, easytier-web-embed
   • Supports compressed packages: .zip, .tar.gz, .tar
3. Configure network parameters on the EasyTier Core page
4. Enable and save the configuration

Configuration Methods

Two configuration methods are supported:

1. Command-line parameters: Configure parameters through the LuCI interface
2. Configuration file: Use the /etc/easytier/config.toml configuration file

Function Pages

• Status - View running status, version info, connection info, and real-time traffic
• EasyTier Core - Configure core parameters (network name, secret key, nodes, etc.)
• Self-hosted Console - Configure easytier-web console
• Logs - View running logs with level filtering support
• Upload Program - Upload and manage EasyTier binary files

🛠️ Development Guide

Tech Stack

• Backend: Lua 5.1 (LuCI legacy architecture)
• Frontend: HTML + CSS + ES5 JavaScript
• Rendering: Server-side rendering (SSR)
• Internationalization: LuCI native i18n (.po files)

Development Requirements

Compatibility Principles

• ✅ Must be compatible with OpenWrt 18.06 ~ 26.x
• ✅ Use LuCI Lua1 architecture (also compatible with Lua2)
• ❌ Do not use LuCI JS framework (view.js/form.js/rpc.js)
• ❌ Do not use ES6+ syntax (let/const/arrow functions/fetch)

Frontend Standards

// ✅ Allowed
var xhr = new XMLHttpRequest();
function handleClick() { }
document.getElementById('id');

// ❌ Forbidden
const data = await fetch('/api');
let result = () => {};
import module from 'module';

Backend Standards

-- ✅ Use Lua1 API
local http = require "luci.http"
local uci = require "luci.model.uci".cursor()
http.write_json({success = true})

-- ❌ Do not use Lua2-specific syntax
-- Do not use new LuCI JS API

Internationalization

-- In Lua
local translate = i18n.translate
translate("Text to translate")

-- In HTM templates
<%:Text to translate%>

-- In JavaScript (injected by Lua)
var msg = '<%=translate("Text")%>';

API Design Standards

-- API path format
entry({"admin", "vpn", "easytier", "api_name"}, call("function_name")).leaf = true

-- Return JSON format
function api_name()
    luci.http.prepare_content("application/json")
    luci.http.write_json({
        success = true,
        data = {},
        message = "Success"
    })
end

🐛 Troubleshooting

Interface Not Showing After Installation

# Clear LuCI cache
rm -rf /tmp/luci-*
# Re-login to LuCI interface

util.pcdata Warning

sed -i 's/util.pcdata/xml.pcdata/g' /usr/lib/lua/luci/model/cbi/easytier.lua

Configuration File Conflict

When upgrading, if a configuration file conflict is prompted, the old configuration will be retained and the new configuration saved as /etc/config/easytier-opkg. You can ignore this error.
