用shell編寫啓動腳本

服務端開發常常會寫些後臺運行的腳本，須要重啓和啓動時候都比較麻煩。常常是nohup python xxx&,ps -ef|grep xxx而後kill。利用下面的shell腳本能夠實現簡單的啓動中止方式 怎加開發效率。

僅需修改startcmd和filename便可：

例如保存爲startup.sh

startcmd="php control.php"
filename="control.php"

op=$1
[ -z "$op" ] && op=start

start(){
    nohup $startcmd >> logs/$filename.log  2>&1 &
}
stop(){
    pid=`ps -ef|grep $filename|grep -v "grep" |head -n1|awk '{print $2}'`
    kill -9 $pid
    printf "pid %s is killed.\n" $pid
}


case $op in
start)
echo "Starting  Now......"
start
echo "Starting  Finished"
;;
stop)
echo "Stopping  Now......"
stop
echo "Stopping  Finished"
;;
restart)
echo "Restart  Now......"
stop
start
echo "Restart  Finished"
;;
*)
esac

啓動 startup.sh start
中止 startup.sh stop
重啓 startup.sh restart
