Run locally
Running Hydrui locally is fairly straight-forward. The first thing you need to do is download the appropriate executable binary files for your platform. Then, you can simply run the executable file. This will give you a basic Hydrui server in client-only mode (same as the hosted service).
Download the appropriate binary
Each platform supported by Hydrui has a corresponding set of binaries.
Go to the latest release, and you will see binaries for each supported system.
If your system is not listed, it may still be possible to compile from source.
Run binary
Windows
Under Windows, you can just double click the application. A rudimentary user interface is provided, and you should see an icon appear in your system tray. If you want Hydrui to run at startup, you could put it in your Startup folder.
Click the icon to open up Hydrui configuration. By default, Hydrui Server operates in client-only mode, since server mode requires some configuration; you can do that configuration in the UI.
Note that the UI currently does not have a way to edit the default log-in username/password. For now, you can generate an htpasswd file using the online htpasswd editor.
Other platforms
Under Linux, macOS, FreeBSD and other platforms, the primary interface is the CLI for now.
After extracting the program, mark it executable.
$ unzip hydrui-linux-amd64.zip
$ chmod +x ./hydrui-linux-amd64
Run the program from a terminal. For example:
$ ./hydrui-linux-amd64
This will run Hydrui in client-only mode. To run in server mode, you need to supply the relevant flags:
$ ./hydrui-linux-amd64 -server-mode -hydrus-api-key=xxx -hydrus-url=http://localhost:45869
Note that this will default to an insecure setup where the username and password is admin. You can supply an htpasswd file with the -htpasswd flag. For more information on what flags you can use, try passing -help.
It is also possible to run the Windows version of Hydrui Server under Wine, if you wish. Win32 is the true universal ABI, after all. Just note that the UI is a bit uglier than it even normally is when running under Wine.
htpasswd setup
When running in server mode, you can use the online htpasswd editor to make an htpasswd file, or you can use the htpasswd tool from the Apache httpd server package. Please note that Hydrui Server currently only supports Bcrypt password hashes in htpasswd files. You could create a new htpasswd file using the Apache httpd htpasswd tool like this:
$ htpasswd -B -c htpasswd.txt test
Enter password:
Re-type new password:
Adding password for user test
$
This will create a new htpasswd.txt file with one user, test, with the password you enter at the prompt.
