shell脚本实现多台服务器自动巡检
摘要：
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。
具体实现脚本：
cat check.sh
#! /bin/bash echo "start running" | tee -a LANG=en set `date` path="/home/check" echo "start running" | tee -a $path/log/$1-$2-$3.log if [ -d /home/check/result/$1-$2-$3 ]; then echo '' else mkdir -p /home/check/result/$1-$2-$3 echo `date +"%Y/%m/%d-%H:%M:%S"` "create " "$1-$2-$3" "directory success "|tee -a $path/log/$1-$2-$3.log fi echo `date +"%Y/%m/%d-%H:%M:%S"` "starting reading linuxconfig.txt " |tee -a $path/log/$1-$2-$3.log cat "$path"/config/linuxconfig.txt| while read line; do ip=`echo $line |cut -d '=' -f2` echo `date +"%Y/%m/%d-%H:%M:%S"` "check LINUX " $ip " starting " |tee -a $path/log/$1-$2-$3.log ( sleep 1 #echo account echo root sleep 1 #echo password echo root sleep 3 echo "free -k" echo "" echo "df -k" echo "" #memory_used_rate echo "ps -ef| grep java" echo "" echo "netstat -an|egrep -n '80|22|21|23|9043|9044|45331|45332|39194|19195'" echo "" #echo "ifconfig -a " echo "/sbin/ip ad" echo "" echo " tail -2000 /var/log/messages | grep -v snmp |grep -i error " echo "" echo "/bin/dmesg |grep -i error" echo "" echo "top -n1|sed -n '1,5p'" echo "exit" echo "/usr/bin/vmstat 1 3" echo "" sleep 5 )|telnet $ip >/home/check/result/$1-$2-$3/$ip-$1-$2-$3-$4.txt echo `date +"%Y/%m/%d-%H:%M:%S"` "check LINUX " $ip " end" |tee -a $path/log/$1-$2-$3.log echo "" | tee -a $path/log/$1-$2-$3.log done echo `date +"%Y/%m/%d-%H:%M:%S"` "end reading linuxconfig.txt " |tee -a $path/log/$1-$2-$3.log echo `date +"%Y/%m/%d-%H:%M:%S"` "starting reading AIXconfig.txt " | tee -a $path/log/$1-$2-$3.log cat "$path"/config/AIXconfig.txt| while read line; do ip=`echo $line |cut -d '=' -f2` echo `date +"%Y/%m/%d-%H:%M:%S"` "check IBM AIX " $ip " starting " |tee -a $path/log/$1-$2-$3.log ( sleep 1 #echo account echo root sleep 1 #echo password echo root sleep 5 echo "" #echo "df -k" echo "df -g" echo "" #memory_used_rate echo "ps -ef| grep java" echo "" echo "netstat -an|egrep -n '80|22|21|23|9043|9044|45331|45332|39194|19195'" echo "" echo "ifconfig -a" echo "" echo "topas" echo "exit" sleep 5 )|telnet $ip >/home/check/result/$1-$2-$3/$ip-$1-$2-$3-$4.txt echo `date +"%Y/%m/%d-%H:%M:%S"` "check IBM AIX " $ip " end " |tee -a $path/log/$1-$2-$3.log echo "" | tee -a $path/log/$1-$2-$3.log done echo `date +"%Y/%m/%d-%H:%M:%S"` "end reading AIXconfig.txt " | tee -a $path/log/$1-$2-$3.log zip -r /home/check/result/$1-$2-$3/$1-$2-$3.zip /home/check/result/$1-$2-$3/* echo "End running "
注意：
该脚本的巡检是基于TELNET服务所以被检服务器必须开启TELNET服务

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############################

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

这样就只需在ftp服务器上巡检所有的服务器即可
脚本五

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。
脚本代码：
shellsh.sh:
#!/bin/bash login_info=$1 gather_server_ip=$2 gather_server_password=$3 grep_ip=`ifconfig | grep '\([[:digit:]]\{1,3\}\.\)\{3\}[[:digit:]]\{1,3\}' --color=auto -o | sed -e '2,5d'` GatherPath="/tmp/GatherLogDirectory" CheckScriptPath="/tmp/CheckScript" if [ $# -ne 3 ]; then echo -e "Parameters if fault!\n" echo -e "Please using:$0 login_info gather_server_ip\n" echo -e "For example: $0 IpAndPassword.txt $grep_ip\n" exit; fi if [ ! -x "$GatherPath" ];then mkdir "$GatherPath" echo -e "The log's path is: $GatherPath" fi cat $login_info | while read line do server_ip=`echo $line|awk '{print $1}'` server_password=`echo $line|awk '{print $2}'` login_server_command="ssh -o StrictHostKeyChecking=no root@$server_ip" scp_gather_server_checksh="scp checksh.sh root@$server_ip:$CheckScriptPath" /usr/bin/expect<<EOF set timeout 20 spawn $login_server_command expect { "*yes/no" { send "yes\r"; exp_continue } "*password:" { send "$server_password\r" } } expect "Permission denied, please try again." {exit} expect "#" { send "mkdir $CheckScriptPath\r"} expect eof exit EOF /usr/bin/expect<<EOF set timeout 20 spawn $scp_gather_server_checksh expect { "*yes/no" { send "yes\r"; exp_continue } "*password:" { send "$server_password\r" } } expect "Permission denied, please try again." {exit} expect "Connection refused" {exit} expect "100%" expect eof exit EOF /usr/bin/expect<<EOF set timeout 60 spawn $login_server_command expect { "*yes/no" { send "yes\r"; exp_continue } "*password:" { send "$server_password\r" } } expect "Permission denied, please try again." {exit} expect "#" { send "cd $CheckScriptPath;./checksh.sh $gather_server_ip $gather_server_password\r"} expect eof exit EOF done

注：192.168.182.143是被巡检的服务器ip，123456是被巡检的服务器密码。
声明：此脚本将巡检结果用awk和sed以及grep进行了过滤，以便格式化显示和excel进行处理。由于水平有限，如果有大神认为还有更好的解决方案或者这个脚本还有改进的地方，请指出。我们大家共同学习，共同进步。
