## 手順書
1. Increase Swap Size
2. Install MineCraft Server
3. Play MineCraft at Okinawa.rb Server

## 1. Increase Swap Size (cf. [swapファイルを追加する](http://linuxsalad.blogspot.jp/2009/05/swap.html))
1. `cat /proc/swaps`
```
Filename Type Size Used Priority
/dev/dm-1 partition 2093052 814496 -1
```
2. `sudo dd if=/dev/zero of=/swap bs=2G count=5 iflag=fullblock`
```
5+0 records in
5+0 records out
10737418240 bytes (11 GB) copied, 3079.19 s, 3.5 MB/s
```
3. `sudo mkswap /swap`
```
OKINAWARB /home/yasulab% sudo mkswap /swap
[sudo] password for yasulab:
Setting up swapspace version 1, size = 10485756 KiB
no label, UUID=9ac709f4-1232-4583-967a-05e1e79d3235
```
4. `sudo swapon /swap`
5. `sudo echo "/swap swap swap defaults 0 0" >> /etc/sftab`
6. `cat /proc/swaps`
```
Filename Type Size Used Priority
/dev/dm-1 partition 2093052 804008 -1
/swap file 10485756 0 -2
```

## 2. Install MineCraft Server (cf. [#27](https://github.com/okinawarb/meetups/issues/27))
1. `sudo aptitude install openjdk-6-jre`
2. `which java; /usr/bin/java`
3. `mkdir ~/minecraft; cd minecraft`
4. `wget https://s3.amazonaws.com/Minecraft.Download/versions/1.7.9/minecraft_server.1.7.9.jar`
5. `java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui` #=> `/stop` to stop server.

- __Note: Need to consider how to co-exist MineCraft server with [ScreenX TV](http://screenx.tv) server.__
