Bukkit plugins can be installed by following the pattern mentioned below, for any kind of OS:-
- Download the plugin on to your computer (server). The plugin is usually a .jar file. In case you get an archived file, like a .zip or a .rar, or .7z, then you will have to extract the .jar file using the relevant archive manager. In case there are any ReadMe files or text files accompanying the plugin, read them and follow any instructions mentioned in them.
- Place the .jar file in the plugins folder which will be present in the same folder/directory as the craftbukkit.jar file.
- Start the server.
- Once it has fully initiated, type stop in the command/terminal window. This is done to generate any configuration files that might be needed for the plugin. You might have to do certain modifications to the configuration files. There will most probably be a ReadMe file, in such cases, which will tell you what needs to be done.
- Start the server again, and you’ll be good to go.
In case you see errors, on your console or in the logs, you might have some other settings to be altered. You might get help from the same place you got the plugin.
