说明

  • 今天又有一个新需求
    提取所有物理机的IP和其对应的mac地址。

  • 实现过程【你也可以先思考一下我下面的每一步咋实现的，然后再看我的代码，要学会独立思考，才能更快成长。】

    • 1、分别提取每台的ip和mac并记录到文件中【也可以手动复制记录，但我这几百台，不可能每一台都手动复制的】
    • 2、汇总每一台文件中记录的IP和mac到一台主机上面。
    • 3、将汇总的文件分别提取并汇总到一个文件中。
    • 4、导出该文件中的内容即可。

1、2：提取IP和mac

单台【ifconfig命令】

  • 单台提取很简单【真实环境ip不变展示。下面所有IP信息有修改】
[root@node-2 ccx]# sh test.sh 
1.2.3.4 : f6:a4:b4:aa:ac:49
[root@node-2 ccx]# 
[root@node-2 ccx]# cat test.sh 
echo -e "`ifconfig | egrep  1.2.3 | awk '{print $2}'` : `ifconfig | egrep -A3 1.2.3 | grep ether|awk '{print $2}'`"
[root@node-2 ccx]#

记录

  • 提取到以后我们还需要思考一个问题，这是每一台的值，后面我们需要把这个代码放到expect脚本中遍历执行获取所有物理机。
    同时还需要考虑一个问题，每一台独立提取的值怎么汇总？
    我这想到的就是将值放到一个文件中，然后用scp拷贝到某一台上，后面用cat每一个文件用>>追加的方式放到一个文件夹中。
    我这打算全部将每一台的结果放到我node-2主机上的下面目录中，先创建出来
[root@node-2 ~]# cd ccx/
[root@node-2 ccx]# mkdir mak
[root@node-2 ccx]# cd mak
[root@node-2 mak]# pwd
/root/ccx/mak
[root@node-2 mak]#

scp拷贝

  • 所以我每一台上需要做的就是【这是测试代码的，代码可行就放到脚本中】
    • 将ip和mac放到文件中，文件不能重名【否则汇总的时候会冲突】，可以用ip来命名文件名【根据我下面的测试，我这是用的IP，但我最后改成用主机名了】
    • scp将文件拷贝到上面node-2主机上
    • 删除保存ipmak信息文件
这台主机竟然有2个一样的ip，不知道之前配置ip的咋搞的，真的绝。
[root@node-1 ccx]# ifconfig | grep 1.2.3.
        inet 1.2.3.3  netmask 255.255.255.0  broadcast 1.2.3.255
        inet 1.2.3.3  netmask 255.255.255.0  broadcast 0.0.0.0
[root@node-1 ccx]# 

获取信息并放到文件中，没问题
[root@node-1 ccx]# cat mak.sh 
echo -e "`ifconfig | egrep  1.2.3 | awk '{print $2}'` : `ifconfig | egrep -A3 1.2.3 | grep ether|awk '{print $2}'`" > `ifconfig | egrep  1.2.3 | awk '{print $2}'`

expect脚本ip密码准备

建议分开存放，如下，我就分了好几个文件放的。
格式前面ip后面密码，一行一个。

[root@node-2 ccx]# ls | grep iplist
iplist3-4.txt
iplist5-23.txt
iplist61-82.txt
iplist83-104.txt
[root@node-2 ccx]# cat iplist3-4.txt 
1.2.3.3   Dm21*8&qT!9(0)
1.2.3.4   Dm21*8&qT!9(0)
[root@node-2 ccx]#

代码汇总【不可行】

  • 那么开始代码汇总吧
root@node-2 ccx]# cat mak.sh 
#!/bin/bash

cat $1|while read line
do
a=($line)
#/usr/bin/expect<<EOF      
/usr/local/bin/expect<<EOF
spawn ssh root@${a[0]}     
expect {
        "*assword" {send "${a[1]}\r";} 
        "yes/no" {send "yes\r"; exp_continue}
}
expect "*]#" {send "echo -e `ifconfig | egrep  1.2.3 | awk '{print $2}'` : `ifconfig | egrep -A3 1.2.3 | grep ether|awk '{print $2}'` > `ifconfig | egrep  1.2.3 | awk '{print $2}'`\r"}
expect "*]#" {send "sleep 1\r"}
expect "*]#" {send "scp `ifconfig | egrep  1.2.3 | awk '{print $2}'` 5.6.7.134:/root/ccx/mak\r"}
expect {
        "*assword" {send "${a[1]}\r";}
        "yes/no" {send "yes\r"; exp_continue}
}
expect "*]#" {send "sleep 1\r"}
expect "*]#" {send "rm `ifconfig | egrep  1.2.3 | awk '{print $2}'`\r"}
expect "*]#" {send "sleep 1\r"}
expect "*]#" {send "echo ________________________\r"}
expect "*]#" {send "exit\r"}

expect eof
EOF
done
[root@node-2 ccx]#

执行效果

  • 用2个ip执行试试效果
    下面有个sleep 差个1 所以报错了，问题不大，更新脚本代码就好了。
    还有问题，这特么的再每一台上面获取到的ip都是我执行的主机ip，离了个大谱。
    我不知道哪里处问题了，反正这种方式不行了

代码汇总【可行】

  • 上面我们已经知道了需要执行的几条命令，我们用expect的方式不行，获取的ip是执行机的ip，不知道为啥，那么我们就用普通的方式来执行，用shell的方式来执行，这样就没问题了
    但又遇到一个新问题，前面说过，我们写入信息名称是用ip，可我下面这个主机，有2个一样的ip，那就报错了。如下。
[root@node-1 ccx]# sh mak.sh
1.2.3.3
1.2.3.3
Warning: Permanently added '5.6.7.134' (ECDSA) to the list of known hosts.
 Authorized users only. All activity may be monitored and reported

[root@node-1 ccx]# 
[root@node-1 ccx]# cat mak.sh 
#!/bin/bash

echo -e "`ifconfig | egrep  1.2.3 | awk '{print $2}'` : `ifconfig | egrep -A3 1.2.3 | grep ether|awk '{print $2}'`" > `ifconfig | egrep  1.2.3 | awk '{print $2}'`
scp `ifconfig | egrep  1.2.3 | awk '{print $2}'` 5.6.7.134:/root/ccx/mak

[root@node-1 ccx]#
  • 所以，名称我们不能用ip了，改成主机名吧，这样就正常了
[root@node-1 ccx]# cat mak.sh
#!/bin/bash

echo -e "`ifconfig | egrep  1.2.3 | awk '{print $2}'` : `ifconfig | egrep -A3 1.2.3 | grep ether|awk '{print $2}'`" > `hostname`
scp `hostname` 5.6.7.134:/root/ccx/mak

[root@node-1 ccx]#

sh代码【版本1，有局限，了解为主】

  • 所以每一台上面需要执行的最终代码如下
    这个代码放到某一台上面就好，后面执行的时候scp把代码拷贝过去执行。
[root@node-1 ccx]# cat mak.sh 
#!/bin/bash

echo -e "`ifconfig | egrep  1.2.3 | awk '{print $2}'` : `ifconfig | egrep -A3 1.2.3 | grep ether|awk '{print $2}'`" > `hostname`
scp `hostname` 5.6.7.134:/root/ccx/mak
rm `hostname`
[root@node-1 ccx]#
  • 上面代码我放到存放所有代码的主机node-2上，并命名为mac-sh.sh
[root@node-2 ccx]# cat mac-sh.sh
#!/bin/bash

echo -e "`ifconfig | egrep  1.2.3 | awk '{print $2}'` : `ifconfig | egrep -A3 1.2.3 | grep ether|awk '{print $2}'`" > `hostname`
scp `hostname` 5.6.7.134:/root/ccx/mak
rm `hostname`
[root@node-2 ccx]#

执行

  • 上面代码有一个条件，就是如果你的虚拟机不是互相免密的话，文件就拷不成功，会弹出scp拷贝输入密码界面，同时也会卡在这个界面。
    我下面是双方免密的主机，所以是正常的。
[root@node-1 ccx]# sh mak.sh
Warning: Permanently added '5.6.7.134' (ECDSA) to the list of known hosts.

[root@node-1 ccx]#
  • 卡住的界面我就不测试了，不然代码还得改回去，麻烦很。
    反正就是会卡在scp输入密码的界面，这个应该没啥可说的。

sh代码【版本2，可行且无局限】

我其实也没做啥改动，就是把删除改到另外一个脚本中了而已。
注：必须是以scp结尾。

[root@node-2 ccx]# cat mac-sh.sh 
#!/bin/bash

echo -e "`ifconfig | egrep  1.2.3 | awk '{print $2}'` : `ifconfig | egrep -A3 1.2.3 | grep ether|awk '{print $2}'`" > `hostname`
scp `hostname` 1.2.3.4:/root/ccx/mak
[root@node-2 ccx]#

expect代码【版本1，对应上面sh代码的版本1】

  • 上面代码是需要执行的代码嘛
    那我这还需要写一个交互脚本运行这些脚本噻。
[root@node-2 ccx]# cat mak.sh
#!/bin/bash

cat $1|while read line
do
a=($line)
#/usr/bin/expect<<EOF      
/usr/local/bin/expect<<EOF
spawn ssh root@${a[0]}     
expect {
        "*assword" {send "${a[1]}\r";} 
        "yes/no" {send "yes\r"; exp_continue}
}
expect "*]#" {send "scp 5.6.7.134:/root/ccx/mac-sh.sh /root/\r"}
expect {
        "*assword" {send "${a[1]}\r";}
        "yes/no" {send "yes\r"; exp_continue}
}
expect "*]#" {send "sh /root/mac-sh.sh\r"}
expect "*]#" {send "sleep 1\r"}
expect "*]#" {send "rm /root/mac-sh.sh\r"}
expect "*]#" {send "echo ________________________\r"}
expect "*]#" {send "exit\r"}

expect eof

done
[root@node-2 ccx]#

expect代码【版本2，对应上面sh代码的版本2】

scp代码在expect中使用说明

  • 我前面不是说过嘛，如果直接把scp放到expect中执行的话， scp获取到是值是我执行主机的信息。
  • 我去网上找了一下，原来scp要用spawn来执行。。。。。我下面复制的网上内容。
    • -c 表示可以在命令行下执行except脚本；
    • spawn 命令激活一个unix程序来交互，就是在之后要执行的命令；
    • expect “aaa” 表示程序在等待这个aaa的字符串；
    • send 向程序发送字符串，expect和send经常是成对出现的，比如当expect“aaa”的时候，send“bbb”。
    • scp执行脚本，如下
#! /bin/sh
expect -c "
    spawn scp -r /home/tseg/hello $name@10.103.240.33:/home/$name/
    expect {
        \"*assword\" {set timeout 300; send \"$pass\r\"; exp_continue;}
        \"yes/no\" {send \"yes\r\";}
    }
expect eof"

解释：
第二行： -c 表示可以不用与控制台交互；
第三行：spawn激活一个scp的unix程序；
第五行：expect期待含有“assword”的字符串，设置连接时间最大为300毫秒，如果出现这个字符串，就send 变量pass代表的密码字符串， exp_continue表示执行下面的匹配；
第六航：expect期待含有“assword”的字符串，设置连接时间最大为300毫秒，如果出现这个字符串，就send 变量pass代表的密码字符串；
第八行：表示结束。

  • 我根据这个其实做了好些尝试，发现也有局限，如果按上面的方式，首先必须要当前主机上有expect命令，可是这个命令我并不会再每一台上面都安装，所以我肯定是不会用的。
    我们可以换一种思路嘛，把ssh直接换成scp不就好了，这样的话只需要我执行机有expect命令就好了。
    而且实现方法也很简单，就是再当前主机scp拷贝别的主机文件，这个应该会吧？
    而且批量的话， 我们一样嘛，遍历文件ip嘛，而且密码也可以遍历文件，这样更方便呢。
    下面要实现的话得单独跑一次脚本，我这肯定不用的，只是告诉你这样可以实现，我后面有更牛逼的使用方法。

  • 看记录文件
    我就跑了一个ip信息文件【我ip都是分多个文件存放的】
[root@node-2 ccx]# cd mak
[root@node-2 mak]# ls
node-1.domain.tld  node-2.domain.tld  node-3.domain.tld  stor-1  stor-10  stor-12  stor-13  stor-14  stor-15  stor-16  stor-17  stor-18  stor-19  stor-2  stor-20  stor-21  stor-22  stor-3  stor-4  stor-5  stor-6  stor-7  stor-8  stor-9
[root@node-2 mak]#

3、汇总信息【遍历目录文件】

  • 所谓汇总
    • 1、获取目录下的所有文件名
    • 2、cat 这些文件名，将里面的内容追加到一个文件中即可。
  • 获取目录下的所有文件名
    我网上找了下这种代码，都是复制粘贴的如下代码【没营养，还不好使】
    下面代码，执行结果发现没，遍历了2次确实没啥问题，但是每一次都是获取了所有内容啊【我目录下当前就2个文件】，这样我还cat个der，我必须要一次一个值，这样遍历所有目录文件。
[root@node-2 ccx]# cat while.sh 
#!/bin/bash

files=$(ls mak)
for filename in $files ; do
       echo $files 
done
[root@node-2 ccx]# 
[root@node-2 ccx]# sh while.sh 
node-1.domain.tld node-2.domain.tld
node-1.domain.tld node-2.domain.tld
[root@node-2 ccx]#

获取目录下所有文件名【while】

  • 百度不行，靠自己写呗，for有问题我就用while
    好像也不难，反正while可以就行了，如下，一次一个值，遍历完目录下所有的值。
[root@node-2 ccx]# cat while.sh 
#!/bin/bash

 ls mak|while read line
do
        echo $line 
done
[root@node-2 ccx]# 
[root@node-2 ccx]# sh while.sh 
node-1.domain.tld
node-2.domain.tld
[root@node-2 ccx]#

汇总信息

  • 上面文件名称已经可以获取到了，那么下面就简单了，cat结合>> 即可
    代码如下
[root@node-2 ccx]# cat while.sh
#!/bin/bash

#files=$(ls mak)
#for filename in $files ; do
#       echo $files 
#done

 ls mak|while read line
do
#       echo $line 
        cat mak/$line >> mactest.txt
done
[root@node-2 ccx]#
  • 执行代码看看效果
    没问题了。
[root@node-2 ccx]# cat while.sh
#!/bin/bash

#files=$(ls mak)
#for filename in $files ; do
#       echo $files 
#done

 ls mak|while read line
do
#       echo $line 
        cat mak/$line >> mactest.txt
done
[root@node-2 ccx]# 
[root@node-2 ccx]# sh while.sh 
[root@node-2 ccx]# cat mactest.txt 
1.2.3.3
1.2.3.3 : 02:2a:e8:bc:05:4a
8e:99:1d:d1:d5:67
1.2.3.4 : f6:a4:b4:aa:ac:49
[root@node-2 ccx]#
  • 但是上面呢，因为123.3有2个ip，所以值有点乱，后面得手动删除这种重复ip信息，有点烦，不过应该不多，无所谓了，
    当然，你想有个跨行隔开每一个值也是可以的，echo打印\n就行了，如下
[root@node-2 ccx]# cat while.sh
#!/bin/bash


 ls mak|while read line
do
#       echo $line 
        cat mak/$line >> mactest.txt
        echo -e "\n"
done
[root@node-2 ccx]# 
# 这样清晰多了
[root@node-2 ccx]# sh while.sh 
[root@node-2 ccx]# cat mactest.txt 
1.2.3.3
1.2.3.3 : 02:2a:e8:bc:05:4a
8e:99:1d:d1:d5:67
1.2.3.4 : f6:a4:b4:aa:ac:49
1.2.3.3
1.2.3.3 : 02:2a:e8:bc:05:4a
8e:99:1d:d1:d5:67
1.2.3.4 : f6:a4:b4:aa:ac:49
1.2.3.3
1.2.3.3 : 02:2a:e8:bc:05:4a
8e:99:1d:d1:d5:67


1.2.3.4 : f6:a4:b4:aa:ac:49

上面代码执行了以后，就得到了下面的所有信息了
在这里插入图片描述
我之前说过，我这有些重复的ip，所以信息有个会多一个，我vi编辑删除以后，就可以复制到本地excel里面了。

现成脚本需要改的地方说明

  • 上面的应该知道要修改些啥东西了吧？
    我这换了一个地方跑，修改的地方其实只有ip【环境也要复刻哈，跟着上面一步步来，有不懂的留言或私信一起交流学习。】
    而且也要先执行单个脚本命令，确定没问题了再把命令放到脚本中

没有ifconfig命令解决

  • 我上面sh脚本中是用的ifconfig命令嘛，后面我发现我们有好多的主机没有ifconfig命令，所以也就没提取到值，离了个普，ifconfig都没有，系统也太精简了！！
    所以就将ifconfig改为ip a 嘛，但条件也得变，如我这sh脚本中的提取ip和mac代码就变成下面了
    其他执行方式这些都一样，就是将echo那行代码改一下就好了。
[root@controller01 ccx]# cat mac-sh.sh 
#!/bin/bash

echo -e "`ip a | grep 11.12.13 | awk '{print $2}'` : `ip a | egrep  -B2 11.12.13  | grep ether | awk '{print $2}'`" > `hostname`
scp `hostname` 11.12.13.6:/root/ccx/mak
[root@controller01 ccx]#
  • ipa多了个掩码嘛，我们后面可以再excel中替换就好了。【wps可能不行，office可以】
    在这里插入图片描述
    我上面wps不得行，下面用office才替换成功的。

excel匹配没有成功的数据

  • 每一期都有那么几台，取不到值，有些是root被限制直登了，有些是没有ifconfig命令，目前就发现这2种情况。。。。.
    那就放execel里面匹配看那几台没有取到值，手动登上去复制粘贴呗。。。。
    vlookup，不会的取看我这篇文章【一般都是用少的匹配多的，这样看着轻松】：
    excel两行数据匹配【vlookup、countif】
  • 如下，我这就缺32，那么就手动取复制呗
    在这里插入图片描述
