fedora21架设minecraft服务器

上周刚刚从dota2的坑中跳出来，这周就又跳入了mincraft的大坑中。作为买不起官网服务的穷人，自己玩单机也未免过于孤单。虽然网上有很多现成的“私服”，不过又不想受别人限制，那就自己搭建一个呗！

首先安装jdk，fedora执行： sudo yum install java-1.8.0-openjdk.x86_64 ubuntu则是： suso apt-get install openjdk-7-jre-headless 安装完成后可以执行java命令看是否成功，然后下载minecraft的服务端：

wget https://s3.amazonaws.com/Minecraft.Download/versions/1.8.8/minecraft_server.1.8.8.jar

这步最好新建一个目录，因为运行程序后会在当前目录生成一些文件。

运行：java -Xmx1024M -Xms1024M -d64 -jar minecraft_server.1.8.8.jar nogui 这里官网提示可用内存至少在1G以上，我自己添加了-d参数因为我的系统是64位的。

root@localhost:/var/local/mine# java -Xmx1024M -Xms1024M -jar minecraft_server.1.8.8.jar nogui
[02:37:30] [Server thread/INFO]: Starting minecraft server version 1.8.8
[02:37:30] [Server thread/INFO]: Loading properties
[02:37:30] [Server thread/WARN]: server.properties does not exist
[02:37:30] [Server thread/INFO]: Generating new properties file
[02:37:30] [Server thread/WARN]: Failed to load eula.txt
[02:37:30] [Server thread/INFO]: You need to agree to the EULA in order to run the server. Go to eula.txt for more info.
[02:37:30] [Server thread/INFO]: Stopping server

第一次运行后会出现这个错误，编辑当前目录下生成的eula.txt，把eula设置为true即可。

修改保存后再次运行：

root@localhost:/var/local/mine# java -Xmx1024M -Xms1024M -jar minecraft_server.1.8.8.jar nogui
[02:37:49] [Server thread/INFO]: Starting minecraft server version 1.8.8

[02:37:59] [Server thread/INFO]: Done (9.702s)! For help, type "help" or "?"

这里服务就成功启动了，但注意，这里服务端是正版的，如果使用的是盗版客户端，比如HMCL，选择多人游戏并添加服务器地址后是无法链接的，需要修改配置文件server.properties，把其中online-mode的值改成false，之后再次启动服务器即可链接。
