export RUI_BITRATE=1024 export RUI_FRAME_SKIP=2在这里插入代码片
<>方法一 pidof
targe=`pwd`/"exec/0.3.8/attest" targe_server=`pwd`/server/nginx kill -9 `pidof
$targe` kill -9 `pidof $targe_server` chmod 777 $targe chmod 777 $targe_server
<>方法二 th=ps |grep "$targe"|grep -v "grep"|wc -l
while(true) do th=`ps |grep "$targe"|grep -v "grep"|wc -l` if [ $th -eq 0 ];
then $targe $* & fi th2=`ps |grep "nginx"|grep -v "grep"|wc -l` if [ $th2 -eq 0
]; then $targe_server -p `pwd`/server fi sleep 3 done
<>方法三
假设程序运行脚本如下
nohup ./wdt_daemon.sh Rv1126Daemon ./rv1126_daemon &
wdt_daemon.sh的脚本如下：
while [ true ] do time=$(date "+%Y-%m-%d %H:%M:%S") pid=`ps | grep "$1"| grep -
v grep| grep -v "$0" | grep -v grep |head -n 1| awk '{print $1}'` if [ "${pid}"
="" ] then echo "${time} cannot check $1 process,reboot process" >> "${logFile}"
cd/mnt/app/web nohup $2 >/dev/null 2>&1 & sleep 5 pid1=`ps | grep "$1"| grep -
v grep| grep -v "$0" | grep -v grep |head -n 1| awk '{print $1}'` if [ "${pid1}"
="" ];then echo "${time} re exec $2 fail" >> "${logFile}" cp -rvf /
oem/recovery/web/oem/app else echo "${time} re exec $2 success,pid=${pid1}" >>
"${logFile}" fi else echo "${time} $1 running,pid=${pid}" >> "${logFile}" fi
sleep 15 #check file size limit_size_log done
<>方法四
## 假设程序名是python promotion pid=`ps -ef|grep "python promotion"|grep -v grep|awk
'{print $2}'` kill -SIGTERM $pid echo "process ${pid} killed"
<>判断程序是否在运行
#! /bin/bash already_run=`ps -ef|grep "python promotion"|grep -v grep|wc -l` if
[ ${already_run} -ne 0 ];then echo "promotionService already Running!!!! Stop
it first" exit -1 fi nohup python promotionService.py 8093 &
如果存在，already_run值是1
