一、Polysh簡介
Polysh 是一個交互式命令,可以在一臺服務器上批量的對一批服務器進行處理,運行交互式命令。Polysh可以同時登錄多個遠程主機,而不需要通過relay一臺一臺的登錄,并執行相同的指令,方便了問題的排查和定位,大大減少了我們的工作量。

Polysh is a tool to aggregate several remote shells into one. It is used to launch an interactive remote shell on many machines at once. It is written in Python and requires Python ≥ 2.4. |
注: 官方解釋:Polysh 是一個由幾個遠程腳本集合而成的工具,它被用于在許多服務器上運行一個交互式的遠程腳本,由 Python 編寫,最低要求為 Python 2.4 。
二、polysh安裝
通過relay登錄staging機器,執行如下命令安裝polysh。安裝目錄為用戶目錄: /opt/hl/。
1.已安裝python的安裝

wget wget http: //guichaz . free .fr /polysh/files/polysh-0 .4. tar .gz tar -zxvf polysh-0.4. tar .gz vim prod-polysh.sh |
腳本內容如下:
1

|
#10.252.176.33,10.252.176.35是你要鏈接的機器ip python /opt/hl/polysh-0 .4 /polysh .py {10.252.176.33,10.252.176.35} |
開放給其他用戶可執行的權限
1
|
chmod 777 prod-polysh.sh |
2.未安裝python的安裝

wget wget http: //guichaz . free .fr /polysh/files/polysh-0 .4. tar .gz tar -zxvf polysh-0.4. tar .gz cd polysh-0.4 su python setup.py install vim prod-polysh.sh |
腳本內容如下:

|
#10.252.176.33,10.252.176.35是你要鏈接的機器ip python /opt/hl/polysh-0 .4 /polysh .py {10.252.176.33,10.252.176.35} |
開放給其他用戶可執行的權限
1
|
chmod 777 prod-polysh.sh |
三、Xshell配置Xagent(mac可跳過這一步)
打開文件-屬性,選擇SSH選項,選擇”使用密碼處理的Xagent(SSH代理)”。然后將Xshell重啟。
四、polysh使用
4.1.使用方法一
1
|
polysh 10.252.176.33 10.252.176.35 |
4.2.使用方法二
1
|
. /prod-polysh .sh |
則會出現如下提示信息
1
2
|
[---hl-----]$ . /prod-polysh .sh ready (8) |
ready (8) 表示 8臺機器已經連接完畢,可以執行查詢命令。exit或Crtl+z都可以退出。
4.3.執行命令
1
2
|
ready (8)> cd /opt/hl ready (8)> pwd |
顯示如下:
1
2
|
10.252.176.33: /opt/hl 10.252.176.35 : /opt/hl |
五、源碼
可以通過git獲取polysh的源碼
1
|
git clone git: //repo .or.cz /polysh .git |
六、其他
以冒號開頭的指令不會發送到遠程主機,polysh會執行以冒號開頭的指令,例如:
