在 Centos 上安装 Minecraft 服务器

在过去的 3 周里，我 10 岁的女儿恳求我为她建立一个 minecraft/bukkit 服务器，我正尝试在运行 Centos6.4 的 VPS 上这样做。我正在关注https://forums.bukkit.org/threads/tutorial-centos-bukkit-installation.56371/，只不过我安装的是 Oracle Java JDK-7u45 而不是 JDK-7u2。我有一个名为“minecraft”的常规用户，我正尝试在该用户下运行该服务。

在第 6 步中，它描述了/etc/init.d/minecraft我已完成的创建（脚本重复如下）。我假设如果我希望服务以用户“minecraft”的身份运行，则需要文件所有者为“minecraft”而不是“root”，对吗？

在第 10 步，它显示通过运行来启动服务service minecraft start。执行此操作时，我得到以下信息。有什么建议吗？

[minecraft@vps ~]$ service minecraft start
craftbukkit.jar was not running... starting.
Could not start craftbukkit.jar.
[minecraft@vps ~]$ su
Password:
[root@vps minecraft]# service minecraft start
craftbukkit.jar was not running... starting.
Could not start craftbukkit.jar.
[root@vps minecraft]#

编辑。我​​需要在两行中的任意一行craftbukkit.jar中用全名替换吗？此外，第二行是否需要根据 Java 配置进行修改？craftbukkit-1.6.4-R1.0.jar/etc/init.d/minecraft
