Minecraft server 만들기 실습

# Minecraft server ## VM 생성    ## 2: Prepare the data disk ``` sudo mkdir -p /home/minecraft sudo mkfs.ext4 -F -E lazy_itable_init=0,\ lazy_journal_init=0,discard \ /dev/disk/by-id/google-minecraft-disk ``` ### Result ``` sudo mkfs.ext4 -F -E lazy_itable_init=0,\ > lazy_journal_init=0,discard \ > /dev/disk/by-id/google-minecraft-disk mke2fs 1.43.4 (31-Jan-2017) Discarding device blocks: done Creating filesystem with 13107200 4k blocks and 3276800 inodes Filesystem UUID: b7c787e3-4996-4c22-a21b-2a7fc266f091 Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000, 7962624, 11239424 Allocating group tables: done Writing inode tables: done Creating journal (65536 blocks): done Writing superblocks and filesystem accounting information: done ``` ### Mount ``` sudo mount -o discard,defaults /dev/disk/by-id/google-minecraft-disk /home/minecraft ``` ## 3. Install and run the application ### Java 설치 ``` sudo apt-get update sudo apt-get install -y default-jre-headless cd /home/minecraft sudo apt-get install wget sudo wget https://launcher.mojang.com/v1/objects/d0d0fe2b1dc6ab4c65554cb734270872b72dadd6/server.jar ``` ### Initialize the Minecraft server ``` sudo apt-get update sudo apt-get install -y default-jre-headless cd /home/minecraft sudo apt-get install wget sudo wget https://launcher.mojang.com/v1/objects/d0d0fe2b1dc6ab4c65554cb734270872b72dadd6/server.jar sudo java -Xmx1024M -Xms1024M -jar server.jar nogui ``` ### 트러블슈팅 **eula.txt** `eula=true` ## Create a virtual terminal screen to start the Minecraft server sudo apt-get install -y screen sudo screen -S mcs java -Xmx1024M -Xms1024M -jar server.jar nogui ## Detach from the screen and close your SSH session sudo screen -r mcs ## Allow client traffic ### Create a firewall rule   ## 5: Schedule regular backups gsutil mb gs://$YOUR_BUCKET_NAME-minecraft-backup gsutil mb gs://$YOUR_BUCKET_NAME-minecraft-backup **Backup.sh** ``` #!/bin/bash screen -r mcs -X stuff '/save-all\n/save-off\n' /usr/bin/gsutil cp -R ${BASH_SOURCE%/*}/world gs://${YOUR_BUCKET_NAME}-minecraft-backup/$(date "+%Y%m%d-%H%M%S")-world screen -r mcs -X stuff '/save-on\n' ``` sudo chmod 755 /home/minecraft/backup.sh . /home/minecraft/backup.sh sudo crontab -e ``` 0 */4 * * * /home/minecraft/backup.sh ``` # Server maintenance ## 정지 sudo screen -r -X stuff '/stop\n' ## Automate server maintenance with startup and shutdown scripts  https://storage.googleapis.com/cloud-training/archinfra/mcserver/startup.sh https://storage.googleapis.com/cloud-training/archinfra/mcserver/shutdown.sh
