一、Polysh簡介
Polysh 是一個(gè)交互式命令,可以在一臺(tái)服務(wù)器上批量的對(duì)一批服務(wù)器進(jìn)行處理,運(yùn)行交互式命令。Polysh可以同時(shí)登錄多個(gè)遠(yuǎn)程主機(jī),而不需要通過relay一臺(tái)一臺(tái)的登錄,并執(zhí)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。
注: 官方解釋:Polysh 是一個(gè)由幾個(gè)遠(yuǎn)程腳本集合而成的工具,它被用于在許多服務(wù)器上運(yùn)行一個(gè)交互式的遠(yuǎn)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(jī)器,執(zhí)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(nèi)容如下:
#10.252.176.33,10.252.176.35是你要鏈接的機(jī)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(zhí)行的權(quán)限
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(nèi)容如下:
#10.252.176.33,10.252.176.35是你要鏈接的機(jī)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(zhí)行的權(quán)限
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(xiàng),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
polysh 10.252.176.33 10.252.176.35
4.2.使用方法二
./prod-polysh.sh
則會(huì)出現(xiàn)如下提示信息
[---hl-----]$ ./prod-polysh.sh
ready (8)
ready (8) 表示 8臺(tái)機(jī)器已經(jīng)連接完畢,可以執(zhí)行查詢命令。exit或Crtl+z都可以退出。
4.3.執(zhí)行命令
ready (8)>cd /opt/hl
ready (8)>pwd
顯示如下:
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
git clone git://repo.or.cz/polysh.git
六、其他
以冒號(hào)開頭的指令不會(huì)發(fā)送到遠(yuǎn)程主機(jī),polysh會(huì)執(zhí)行以冒號(hào)開頭的指令,例如:
ready (2)> :help
:add Add one or many remote shells.
:chdir Change the current directory of polysh (not the remote shells).
:disable Disable sending commands to remote shells.
:enable Enable sending commands to remote shells.
:export_vars Export some environment variables on enabled remote shells.
:help List control commands or show their documentations.
:hide_password Do not echo the next typed line.
:list List remote shells and their states.
:purge Delete disabled remote shells.
:quit Quit polysh.
:reconnect Try to reconnect to disconnected remote shells.
:rename Rename all enabled remote shells with the argument.
:replicate Copy a path from one remote shell to all others
:reset_prompt Change the prompt to be recognized by polysh.
:send_ctrl Send a control character to remote shells.
:set_debug Enable or disable debugging output for remote shells.
:set_log Duplicate every console I/O into the given local file.
:show_read_buffer Print the data read by remote shells.
:upload Upload the specified local path to enabled remote shells.
