## Features
|
|
|
|
- Local HTTP/HTTPS/SOCKS server with/without authentication
|
|
- VMess, Shadowsocks, Trojan (experimental), Snell protocol support for remote connections. UDP is supported.
|
|
- Built-in DNS server that aims to minimize DNS pollution attacks, supports DoH/DoT upstream. Fake IP is also supported.
|
|
- Rules based off domains, GEOIP, IP CIDR or ports to forward packets to different nodes
|
|
- Remote groups allow users to implement powerful rules. Supports automatic fallback, load balancing or auto select node based off latency
|
|
- Remote providers, allowing users to get node lists remotely instead of hardcoding in config
|
|
- Netfilter TCP redirecting. You can deploy Clash on your Internet gateway with `iptables`.
|
|
- Comprehensive HTTP API controller
|
|
|
|
## Install
|
|
|
|
Clash requires Go >= 1.13. You can build it from source:
|
|
|
|
```sh
|
|
$ go get -u -v github.com/Dreamacro/clash
|
|
```
|
|
|
|
Pre-built binaries are available here: [release](https://github.com/Dreamacro/clash/releases)
|
|
Pre-built TUN mode binaries are available here: [TUN release](https://github.com/Dreamacro/clash/releases/tag/TUN). Source is not currently available.
|
|
|
|
Check Clash version with:
|
|
|
|
```sh
|
|
$ clash -v
|
|
```
|
|
|
|
## Daemonize Clash
|
|
|
|
Unfortunately, there is no native or elegant way to implement daemons on Golang. We recommend using third-party daemon management tools like PM2, Supervisor or the like to keep Clash running as a service.
|
|
|
|
In the case of [pm2](https://github.com/Unitech/pm2), start the daemon this way:
|
|
|
|
```sh
|
|
$ pm2 start clash
|
|
```
|
|
|
|
If you have Docker installed, it's recommended to deploy Clash directly using `docker-compose`: [run Clash in Docker](https://github.com/Dreamacro/clash/wiki/Run-clash-in-docker)
|
|
|
|
## Config
|
|
|
|
The default configuration directory is `$HOME/.config/clash`.
|
|
|
|
The name of the configuration file is `config.yaml`.
|
|
|
|
If you want to use another directory, use `-d` to control the configuration directory.
|
|
|
|
For example, you can use the current directory as the configuration directory:
|
|
|
|
```sh
|
|
$ clash -d .
|
|
```
