本文介绍一段,它可以检测某进程或某服务是否正在运行,然后以邮件通知。有需要的朋友参考下
一个简单的shell脚本,用来找出关键的服务是否正在运行,适用于或Unix操作系统。
原文出处:: 该脚本还可以使用电子邮件发送通知。代码:
#!/bin/bash # Name : service.chk 服务检测脚本 ## 根据自己的环境修改 _pgrep="/usr/bin/pgrep" _mail="/usr/bin/mail" ## 环境变量 _chklist="/usr/bin/php-cgi /usr/sbin/nginx /usr/sbin/lighttpd /usr/sbin/mysqld /usr/sbin/apache2 /usr/sbin/named /usr/sbin/pgsqld" ## yes | no _sendemail="no" ## email _email="test@jbxue.com" ## 不要修改如下配置 _failed="false" _service="Service:" _running() { local p="${1##*/}" local s="true" $_pgrep "${p}" >/dev/null || { s="false"; _failed="true"; _service="${_service} $1,"; } [[ "$s" == "true" ]] && echo "$1 running" || { echo -n "$1 not running"; [[ ! -f "$1" ]] && echo " [ $1 not found ]" || echo ; } } ## header echo "Service status on ${HOSTNAME} @ $(date)" echo "------------------------------------------------------" ## Check if your service is running or not for s in $_chklist do _running "$s" done ## Send a quick email update (good for cron jobs) ## [[ "$_failed" == "true" && "$_sendemail" == "yes" ]] && { _mess="$_service failed on $HOSTNAME @ $(date)"; $_mail -s 'Service not found' "$_email" < "${_mess}"; }
下面是一些小段代码,大家也可以参考下
脚本一:
#!/bin/sh
program=XXXX #进程名 sn=`ps -ef | grep $program | grep -v grep |awk '{print $2}'` #获得进程端口号 if [ "${sn}" = "" ] #如果为空,表示进程未启动 then nohup /home/oracle/XXXX & #后台启动进程 echo start ok ! else echo running fi
脚本二:
#!/bin/sh ps -ef |grep ./FileServer > /dev/null 2>&1 #检测进程写入/dev/null if [ $? -eq 0 ] #0为正常 then echo logprocess run ok! else nohup /home/oracle/XXXX &
echo start ok !
fi
脚本三:
#!/bin/sh
count=`ps -fe |grep "a.out" | grep -v "grep" | wc -l`
if [ $count -lt 1 ]; then
/root/sh/restart.sh脚本四:
PNAME="authd"
PATHNAME=/root/cauthd/build/ LENGTH=`ps -ef|grep "$PNAME"|grep -v grep|cut -b 49-200|wc -c ` if test $LENGTH -eq 0 then cd $PATHNAME nohup $PNAME >/dev/null
脚本五:
#! /bin/bash
echo "请输入进程名:" read process echo "你要查找的进程是 $process ,正在查找..." ps > text1 grep "$process" text1 declare -i a=$? if [ $a -eq 0 ] then echo "该进程存在" else echo "该进程不存在" fi rm text1
