shell脚本-监控python是否在运行，没有则重启python(python进程守护)

有时候需要一些python脚本去常链接一些东西，就需要监控是否运行正常。

#!/bin/bash

project1='/root/1.py'
project2='/root/2.py'


for Pro in $project1 $project2

do

PythonPid=`ps -ef | grep $Pro | grep -v grep | wc -l `

echo $Pro
if [ $PythonPid -eq 0 ];
        then
        echo "`date "+%Y-%m-%d %H:%M:%S"`:$Pro is not running" >> /data/logs/python.log

        cd /data

        nohup python  $Pro >output 2>&1 &

        echo "`date "+%Y-%m-%d %H:%M:%S"`:$Pro is starting" >> /data/logs/python.log
        sleep 5
        CurrentPythonPid=`ps -ef | grep $Pro | grep -v grep | wc -l`
        if [ $CurrentPythonPid -ne 0 ];
        then
        echo "`date "+%Y-%m-%d %H:%M:%S"`:$Pro is running" >> /data/logs/python.log
        fi
fi
done
