用于进程检查的shell脚本 判断是否运行某服务(图文)

#!/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@jquerycn.cn"
 
## 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}";
