监控外网58.215.50.37内网10.176.164.112这台服务器,如果不是221.226.93.118这个ip登录,就记录登陆日期和用户#/bin/shlog="/job/jk/log.txt"host=MySQLMaster-o-58.215.50.37-i-10.176.164.112a=0while :;dousessh=$(/usr/bin/who|grep

监控所需要的服务进程，如果不存在就记录日志或者报警。#!/bin/shIP=`ifconfig eth0 | grep "inet addr" | cut -f 2 -d ":" | cut -f 1 -d " "`JAVA_DIR=/usr/java/default/bin/javaMYSQL_DIR=/service/mysql/bin/mysqld_safeSSH_DI

以下是我以前的一个mysqldump备份脚本，将备份集打包ftp传到异地服务器上，脚本修改路径即可。将其放在crontab下。#!/bin/sh logfile=/backup/backup.logLOCALHOST_IP=$(/sbin/ifconfig |grep 'inet addr' |cut -d':' -f2 |cu
