Bukkit定时重启bash脚本，GNU Screen走着

135 Replies

Bukkit服务器我一直用GNU Screen跑，隔两天有时候会不稳定要重启。好麻烦根本就不关心为什么，搞定就行。有bukkit插件可以实现但是咱多没自尊用那个。虽然感觉bash操作Screen也挺邋遢的.. 但是好用！其实不然的话怎么操作后台，nohup倒腾输入流什么的太麻烦了，这种用途还是terminal模拟器好看。
[bash]
#!/bin/bash
#/home/bukkit/restart.sh

i=0
while (( $i < 5 ))
do
if [ "`ps aux|grep -e ‘^bukkit’|grep SCREEN`" != "" ]; then
su bukkit -c ‘screen -S bukkit -X stuff ‘stop`echo -ne ‘\015’`” #`echo -ne ‘\015’` 等于敲下回车
echo "`date` restart.sh:" ‘Stoping bukkit…’
((i+=1))
sleep 5

else
((i+=100))
fi
done

if (( $i == 100 )); then
echo "`date` restart.sh:" ‘Bukkit was not running. Starting…’
fi

if (( $i == 5 )); then
kill `ps aux|grep bukkit|awk ‘{print $2}’`
echo "`date` restart.sh:" ‘Forcibly killing bukkit…’
sleep 1
fi

if [ "`ps aux|grep -e ‘^bukkit’|grep SCREEN`" != "" ]; then
echo "`date` restart.sh:" "ERROR: Couldn’t stop bukkit. Exiting."
exit 1
fi

bash /home/bukkit/start.sh

exit 0
[/bash][bash]
#!/bin/bash
#/home/bukkit/start.sh

if [ "`ps aux|grep -e ‘^bukkit’|grep SCREEN`" == "" ]; then
echo `date` start.sh: "Starting bukkit…"
su bukkit -c "screen -dmS bukkit java -Xincgc -Xmx1000m -jar /home/bukkit/craftbukkit-1.6.4-R2.0.jar"
echo `date` start.sh: "Done."
# else
# echo `date` start.sh: "Bukkit is already running."
fi
exit 0
[/bash]

加到cron里就好，第一行是因为有时候服务器会挂掉..

*/5 * * * * bash /home/bukkit/start.sh >> /home/bukkit/cron.log
0 0 * * * bash /home/bukkit/restart.sh >> /home/bukkit/cron.log

如果不把输出导走会给你一堆mails
