每天自动备份worlds文件夹，方便回档

这里用的是pm2后台管理服务进程，算是screen之外又一个选择吧。
因为是bdlauncher启动的，所以停服是通过向进程发送stop命令，官服的话直接pm2 stop 0即可
上脚本

#!/bin/bash
#启动命令：pm2 start -x "./bdlauncher" --restart-delay=10000 -n mc
#需要备份的世界名，多个文件夹用空格分开
WDLEVEL='zzbd default'
#pm2进程ID
PID=0
#备份路径（当前目录）
BACKPATH=$(dirname $(readlink -f $0))
#准备目录
WDPATH="${BACKPATH}/worlds"
BKPATH="${BACKPATH}/bak"
[ ! -d "${WDPATH}" ] && exit 1
[ ! -d "${BKPATH}" ] && mkdir -p "${BKPATH}"
#停止服务器
pm2 send $PID "stop" 2>> ${BKPATH}/worldbak.log
[ $? -ne 0 ] && { echo "服务器通信异常!! 中止.." >> ${BKPATH}/worldbak.log; exit 1; }
echo "备份时间为 `date +%Y-%m-%d/%H:%M:%S`,备份level为 ${WDLEVEL}" >> ${BKPATH}/worldbak.log
#检查服务器是否关闭
sleep 3
NEXT_WAIT_TIME=0
until [ "$(pm2 ls $PID -m | grep -c "status : waiting restart")" -ge 1 ] || [ $NEXT_WAIT_TIME -eq 4 ]; do
sleep $(( NEXT_WAIT_TIME++ ))
done
[ $NEXT_WAIT_TIME -eq 4 ] && { echo "服务器关闭失败!! 中止.."; exit 1; }
#正式备份
cd ${BKPATH}
for x in $WDLEVEL; do
#世界不存在跳过
[ ! -d "${WDPATH}/${x}" ] && continue
#存档数据未更新跳过
currtime=`date -r ${WDPATH}/${x} +%Y-%m-%d_%H%M%S`
[ -n "`find -maxdepth 1 -name "${x}*.tar.gz"`" ] && lastime=`ls -t ${x}*.tar.gz | head -1` || lastime=''
[ "${lastime}" == "${x}${currtime}.tar.gz" ] && continue
#压缩文件夹
tar fczP ${x}latest.tar.gz ${WDPATH}/${x} > /dev/null
echo "世界 ${x} 备份$([ $? -eq 0 ] && echo "成功" || echo "失败")!!" >> worldbak.log
#只保存前三个备份
ls -A1t $(find -name "${x}*.tar.gz" -type f) | tail -n +4 | xargs rm > /dev/null 2>&1
done
#检查服务器是否重启
sleep 5
NEXT_WAIT_TIME=0
until [ "$(pm2 ls $PID -m | grep -c "status : online")" -ge 1 ] || [ $NEXT_WAIT_TIME -eq 4 ]; do
sleep $(( NEXT_WAIT_TIME++ ))
done
[ $NEXT_WAIT_TIME -eq 4 ] && { echo "服务器重启失败!! 中止.."; exit 1; }
#备份文件名修改为当前存档时间戳
for x in $WDLEVEL; do
[ ! -f "${x}latest.tar.gz" ] && continue
currtime=`date -r ${WDPATH}/${x} +%Y-%m-%d_%H%M%S`
mv -f ${x}latest.tar.gz ${x}${currtime}.tar.gz
done

放到服务器根目录，通过crontab每天自动执行，然后可以愉快的关掉作弊选项了

2020.4.13更新
增加三种模式，冷备份（备份时服务器会重启），热备份，游戏内控制台输入关键词触发备份，上脚本

LOG_TO_FILE=false
#需要备份的世界名，多个文件夹用空格分开
WDLEVEL='zzbd default'
#pm2进程ID
PID=0
#触发备份关键字
BK_KEYWORD="开始备份！"
#！！以上参数请根据实际情况修改！！#
#================================#

pm2性能表现太差劲了，试试supervisor
