In some instances ufw will use named site visitors guidelines, reminiscent of for ssh, which all the time uses port 22 by default, however in less widespread circumstances like this one, we’ll specify the port quantity manually.

1. java -Xms1024M -Xmx1024M -jar minecraft_server_1.18.1.jar noguiEarlier than examining this command’s output, let’s take a closer look at all these command-line arguments, that are tuning your server:

- Xms1024M - This configures the server to start out operating with 1024MB or 1GB of RAM operating. You can increase this restrict in order for you your server to start with extra RAM.
