Linux程序守护脚本

2019-01-28

不废话，直接上脚本，【】注释的下发语句需要按需替换：

#!/usr/bin/env bash

PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:~/bin

export PATH



# 【待替换的进程名】

PRO_NAME=caddy



echo "异想家守护程序，当前路径："

cur_dir=$(pwd)

echo $cur_dir



NUM=0

while( true )

do

NUM=`ps aux | grep -w ${PRO_NAME} | grep -v grep |wc -l`

#echo "${PRO_NAME}进程个数：${NUM}，进程详情："

#MSG=`ps aux | grep -w ${PRO_NAME}`

#echo ${MSG}

if [ "${NUM}" -lt "1" ];then

curDate=$(date "+%Y-%m-%d")

curTime=$(date "+%H:%M:%S")

echo "${PRO_NAME}异常退出，时间：${curDate} ${curTime}"

echo "${PRO_NAME}进程个数少于1，重启进程..."

# 【待替换的指令】

nohup ./caddy &amp;gt;./log_caddy_console.log &amp;amp;

fi

# 【待替换的时间，秒】

sleep 60

done



curDate=$(date "+%Y-%m-%d")

curTime=$(date "+%H:%M:%S")

echo "守护程序异常退出，时间：${curDate} ${curTime}"
