linux进程监控进程监控shell脚本代码脚本代码

主要为大家分享一个监控linux进程的shell脚本，当程序异常退出时可以自动重启，涉及到捕获进程信号与重启

进程的命令与知识

为确保php页面在后台运行，写了一个监控脚本，假设程序异常退出，那么可以自动重启。

shell脚本/usr/local/scripts/receve.sh内容：

#!/bin/bash

#funtion:keep receve.php running

PHP="/usr/local/php5/bin/php"

echo "status is $?"

while [ 1 ]

do

wait $chpid

exitstatus="$?"

echo "child pid=$chpid is gone, $exitstatus" >>/usr/local/scripts/phpshell/receve.php_error.log

echo `date` >> /usr/local/scripts/phpshell/receve.php_error.log

echo "**************************" >>/usr/local/scripts/phpshell/receve.php_error.log

sleep 10

$PHP /home/httpd/$PROGRAM >> /usr/local/scripts/phpshell/receve.out &

#!/bin/bash

echo "" >/tmp/receve_pid.txt

/bin/ps ax | /bin/grep "receve.sh" | /bin/grep -v "grep" | /bin/awk '{print $1}' >/tmp/receve_pid.txt

no1pid=`cat /tmp/receve_pid.txt | sort -r`

no2pid=`cat /usr/local/scripts/phpshell/receve.sid | sort -r`

if [ -z $no1pid ];then

echo "receve.sh pid is null, receve.sh is not running."

else

/bin/kill -9 "$no1pid"

echo "receve.sh killed"

echo "receve.php killed"

fi

rm -rf /usr/local/scripts/phpshell/receve.sid

sleep 3

/usr/local/scripts/receve.sh > /dev/null &

crontab：

复制代码 代码如下:

#restart receve.sh

10 00 * * * /usr/local/scripts/restart_r.sh

注意：脚本命名要避免重复，避免自己kill掉自己的进程。
