运维服务一个项目二十多台（或者多台）服务器，每天要做服务器的性能巡检工作是查看服务器的CPU、内存、磁盘空间是否在正常值范围内。像这样每天或者每个固定时间段都做相同的重复工作，为了简化重复的工作，我写了基于liunx服务器的自动巡检脚本，在crontab中设定一个固定时间进行自动执行即可，以减少人工重复劳动的工作。
环境：
我的项目上主要服务器是LINUX和AIX两种服务器，总数在30台左右。现在的工作量是每周巡检两次，都是手动登录到每台服务器使用相应的命令查看服务器性能参数。
思路：
1、所有的服务器之间的网络都是在同一个局域网内，所有网络两两相通。
2、在其中选择一台性能相对较好或者是服务器运行压力较小的服务器，作为巡检服务器。
3、通过这一服务器来实现对其他服务器的巡检，然后把巡检结果记录到巡检服务器上。
4、每台服务器巡检结果都以时间和ip做命名用来区分，最后将所有巡检结果压缩打包。
5、每次维护人员只需要定时去取这个压缩包查看最后结果即可，免去了对每台服务器都需要登录和输入相同的命令进行查看。

linux服务器的日常巡检脚本
1、需巡检的服务器上定时执行：
#!/bin/sh
echo "------------ daily check begin -----------------" >>dc1.txt
#cd /home/wjlcn/monitor/check
cd /home/wjlcn/monitor/check/
date=`date +%c`
filename=`hostname`_check_`date +%Y%m%d`.txt

echo "------------free -m ----------------" >>dc1.txt
free -m >>dc1.txt
echo "--------------df -h ---------------" >>dc1.txt
df -h >>dc1.txt
echo "---------- tripwire --check ----------">> dc1.txt
/usr/sbin/tripwire --check|sed -n ‘10p;18p;33,37p‘ >>dc1.txt
echo $date >>$filename
cat dc1.txt >>$filename
echo $date >>$filename
echo "--------------- the end ---------------" >>$filename
rm dc1.txt top1.txt
2、定时上传至ftp服务器
# 这样就只需在ftp服务器上巡检所有的服务器即可
#!/bin/sh
cd /home/itownet/monitor/check
LOFFILE=ftp.log
ftp -n >>$LOFFILE <<EOF
open IP
user user password

cd test/pcreport

文件说明
该Shell脚本旨在针对大量Linux服务器的巡检提供一种相对自动化的解决方案。脚本组成有三部分：shellsh.sh、checksh.sh、file.txt；这三个文件需放在一个文件夹下以root权限执行，缺一不可。
脚本用法：
将要巡检的服务器的IP地址和对应的密码全部放入file.txt中保存，每行一个IP对应一个密码即可。然后用如下命令运行：
./ shellsh.sh file.txt192.168.182.143 123456
其中file.txt可以更换文件名，192.168.182.143为你想保存巡检日志的到哪个服务器的服务器IP，123456为该服务器的密码。
运行结果：
运行完后会在192.168.182.143服务器的/tmp目录下升成一个目录，即：GatherLogDirectory这个目录下即存放的是被巡检的服务器的巡检日志，这些日志以被巡检的服务器的IP命名，形如：192.168.182.146.log。在被巡检的服务器上会升成两个目录即：CheckScript、 LocalServerLogDirectory；其中CheckScript中是checksh.sh脚本，LocalServerLogDirectory中存放的是checksh.sh在该服务器上运行后升成的日志。
测试结果：
我只在虚拟机上的三台Linux系统上测试过，分别是Ubuntu、RedHat、Kali。运行正常，平均巡检一个服务器花费3分钟。
