######################这是脚本内容结束部分######################################

日常LINUX巡检命令：
hostname
uname -a
netstat -rn
ifconfig -a
cat /etc/sysconfig/hwconf
cat /proc/meminfo
cat /proc/cpuinfo
cat /proc/swaps
sfdisk -g
df –k
sfdisk –g
dmesg
more /var/log/boot.log
more /var/log/messages

以前写的linux服务器的日常巡检脚本：
 
1、需巡检的服务器上定时执行：

##############脚本开始############################
#!/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 "-----------sar -ru 10 3----------------" >>dc1.txt
sar -ru 10 3 |sed -n '21,25p' >>dc1.txt
echo "------------top -d 1 -n 1 -------------" >>dc1.txt
/usr/bin/top  -b -d 1 -n 1 |sed -n '1,10p' |awk '{print $9,$12}' >top1.txt
sed '1,7d' top1.txt >>dc1.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
#!/bin/sh
cd /home/itownet/monitor/check
LOFFILE=ftp.log
ftp -n >>$LOFFILE <<EOF
open IP
user user  password
binary
cd test/pcreport
put *.txt
bye
EOF
 ########################脚本结束###########################
这样就只需在ftp服务器上巡检所有的服务器即可
