Install

You can build from source:

go get -u -v github.com/Dreamacro/clash

Pre-built binaries are available: release

Requires Go >= 1.10.

Daemon

Unfortunately, there is no native elegant way to implement golang's daemon.

So we can use third-party daemon tools like pm2, supervisor, and so on.

In the case of pm2, we can start the daemon this way:

pm2 start clash

If you have Docker installed, you can run clash directly using docker-compose.

Run clash in docker
