监控进程并自动重启脚本

 

监测py文件是否运行，如果没有重启该目录下的所有py文件

shell脚本，后台运行即可

 

#!/bin/sh

while true
do
    SERVER_MAIN_DIR='/data/crawl_redis/save_redis'
    for main in $(find ${SERVER_MAIN_DIR} -name "*.py" | awk -F"/" '{print $NF}')
    do
        SERVICE_NUM=$(ps -ef | grep "${main}" | egrep -v 'grep|monitor' | wc -l)
        # check service status
        if [ ${SERVICE_NUM} -lt 1 ];then
            echo "Process [${main}] not be found !"
            cd ${SERVER_MAIN_DIR} && \
            nohup python ${main} >> nohup.out 2>&1 &
        else
            echo "Process [${main}] has started... nothing to do"
        fi
    done
    sleep 10
done
