簡易登入，批量執行命令，批量copy檔案shell指令碼【Linux營運之道之指令碼案例】

 

    名稱：satool      PS：可以讓同事門叫成了“傻兔”）

    功能：此指令碼可以批量執行命令，拷貝檔案，簡易登入，無需記住應用伺服器具體IP即可快捷登入

    說明：可以分組批量管理，單線程，不適用每組過百台裝置用也可以，就是等待返回結果時間長短問題）

    用法：需要做ssh免密碼登入。因為是分組管理，所以需要分組設定檔 /tools/function-all-ips 名稱可以自己定，但是後面指令碼需要引用此設定檔）設定檔格式

log_server="10.88.1.78 10.88.1.47 192.168.3.117"lvs="192.168.1.141 192.168.1.142"

    組名=“IP IP IP IP”  這種格式

 

    工具參數：

1. -l      簡易登入模式    

   satool -l  組名

   代碼：

   [root@tools-server sbin]# satool -l lvs1) 192.168.1.1412) 192.168.1.142選擇要已連線的服務器編號(Ctrl+C退出)：

   只需要輸入1，或者2 就可以直接登入，我們就不需要記住LVS的具體IP是多少了

2. -g   批量執行命令 可以加索引】命令需要

   satool -g  組名  "cmd"  "num"(可選)

   代碼：

   [root@tools-server sbin]# satool -g lvs "df -h"192.168.1.141Filesystem            Size  Used Avail Use% Mounted on/dev/mapper/VolGroup00-LogVol0013G  6.9G  5.5G  56% //dev/sda1              99M   13M   82M  14% /boottmpfs                1006M     0 1006M   0% /dev/shm192.168.1.142Filesystem            Size  Used Avail Use% Mounted on/dev/mapper/VolGroup00-LogVol0013G  6.9G  5.5G  56% //dev/sda1              99M   13M   82M  14% /boottmpfs                1006M     0 1006M   0% /dev/shm

        這個功能大多數公司都會有，但是我們有這種情況，比如修改了所有某商務服務器的設定檔，伺服器有20台，我不能一下子全部重啟，那樣就會影響業務了，我們需要的是先重啟前5個觀察一下，沒問題之後在全部重啟。為瞭解決這個問題 -g 加入了第四個參數 就是 索引需要引號），例如：WWW組中有15台機器，我只看前5台的負載情況。

        代碼：

 

[root@tools-server sbin]# satool  -l www1) 192.168.1.2      6) 192.168.1.166  11) 192.168.7.187  16) 192.168.7.1532) 192.168.1.3      7) 192.168.3.1    12) 192.168.7.149  17) 192.168.7.1543) 192.168.1.4      8) 192.168.10.6   13) 192.168.7.150  18) 192.168.7.1554) 192.168.1.5      9) 192.168.7.185  14) 192.168.7.1515) 192.168.1.164   10) 192.168.7.186  15) 192.168.7.152選擇要已連線的服務器編號(Ctrl+C退出)：[root@tools-server sbin]# satool  -g  www "w"  "3"192.168.1.223:47:34 up 57 days,  8:48,  0 users,  load average: 0.00, 0.01, 0.00USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT192.168.1.323:47:34 up 57 days,  8:48,  0 users,  load average: 1.04, 0.70, 0.66USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT192.168.1.423:47:34 up 57 days,  8:48,  0 users,  load average: 3.29, 1.34, 0.84USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT

   索引參數還可以支援負數，即反向選取

        代碼：

 

[root@tools-server sbin]# satool  -g  www "w"  "-3"192.168.7.15523:50:36 up 164 days, 21:52,  0 users,  load average: 0.80, 0.40, 0.24USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT192.168.7.15423:50:36 up 168 days, 11 min,  0 users,  load average: 0.11, 0.23, 0.19USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT192.168.7.15323:50:37 up 160 days,  6:02,  0 users,  load average: 0.91, 0.33, 0.21USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT

    還可以支援非連續的單選

        代碼：

[root@tools-server sbin]# satool  -g  www "w"  "1 4 6"192.168.1.223:51:37 up 57 days,  8:52,  0 users,  load average: 0.00, 0.00, 0.00USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT192.168.1.523:51:37 up 57 days,  9:34,  0 users,  load average: 0.00, 0.01, 0.00USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT192.168.1.16623:51:37 up 301 days, 11:22,  0 users,  load average: 0.17, 0.31, 0.48USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT

  3. -cp   批量把本地的檔案推送到遠端伺服器上單向）可以加索引】 

        satool -cp 組名 src  dest    “num"(可選)

        代碼

 

[root@tools-server tmp]# satool  -cp lvs shdmt.txt  /tmp/192.168.1.141shdmt.txt                                                                     100% 4973     4.9KB/s   00:00192.168.1.142shdmt.txt                                                                     100% 4973     4.9KB/s   00:00

主要功能就是以上這些，其他功能都是輔助的了下面是完整代碼共300多行，有點臃腫，歡迎討論最佳化
