Server installation and configuration

For a full tutorial on setting up a Minecraft server, please read the installation and configuration guide.

Note that these requirements only apply to the Survival version of Minecraft, and not to the Classic version.
Requirements may change depending on the server software, such as using Bukkit and/or mods.

* Note: Linux users should avoid using OpenJDK 6 for server hosting, as it has been known to cause issues

Only the JRE version is required, however, Java JDK will still work.
The more memory that your server has, the better. It is recommended to have at least 3 GB of physical RAM in the computer. That way, plenty of RAM is left over for the operating system, and you have the possibility of allocating more to the Minecraft server as needed.
Minecraft servers, as of 1.1.0, can use multiple cores, so now they will not sit idle and will increase server performance.
Windows or Desktop based Linux distributions aren't recommended for hosting servers, use console based Linux/BSD for maximum performance. ^{[citation needed]}

Here is a simple recommendation to help you get started and/or help decide which hosting option is best for you:

Note that these requirements are for the server only you will need to allocate more resources to the OS!
