Polysh命令实现多日志查询的方法示例
一、Polysh简介
Polysh 是一个交互式命令,可以在一台服务器上批量的对一批服务器进行处理,运行交互式命令。Polysh可以同时登录多个远程主机,而不需要通过relay一台一台的登录,并执行相同的指令,方便了问题的排查和定位,大大减少了我们的工作量。

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: 官方解释:Polysh 是一个由几个远程脚本集合而成的工具,它被用于在许多服务器上运行一个交互式的远程脚本,由 Python 编写,最低要求为 Python 2.4 。
二、polysh安装
通过relay登录staging机器,执行如下命令安装polysh。安装目录为用户目录: /opt/hl/。
1.已安装python的安装

|
wget wget http: //guichaz . free .fr /polysh/files/polysh-0 .4. tar .gz
tar -zxvf polysh-0.4. tar .gz
vim prod-polysh.sh
|
脚本内容如下:
1
2
|
#10.252.176.33,10.252.176.35是你要链接的机器ip
python /opt/hl/polysh-0 .4 /polysh .py {10.252.176.33,10.252.176.35}
|
开放给其他用户可执行的权限
1
|
chmod 777 prod-polysh.sh
|
2.未安装python的安装

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
|
脚本内容如下:
1
2
|
#10.252.176.33,10.252.176.35是你要链接的机器ip
python /opt/hl/polysh-0 .4 /polysh .py {10.252.176.33,10.252.176.35}
|
开放给其他用户可执行的权限
1
|
chmod 777 prod-polysh.sh
|
三、Xshell配置Xagent(mac可跳过这一步)
打开文件-属性,选择SSH选项,选择”使用密码处理的Xagent(SSH代理)”。然后将Xshell重启。
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
|
则会出现如下提示信息
1
2
|
[---hl-----]$ . /prod-polysh .sh
ready (8)
|
ready (8) 表示 8台机器已经连接完毕,可以执行查询命令。exit或Crtl+z都可以退出。
4.3.执行命令
1
2
|
ready (8)> cd /opt/hl
ready (8)> pwd
|
显示如下:
1
2
|
10.252.176.33: /opt/hl
10.252.176.35 : /opt/hl
|
五、源码
可以通过git获取polysh的源码
1
|
git clone git: //repo .or.cz /polysh .git
|
六、其他
以冒号开头的指令不会发送到远程主机,polysh会执行以冒号开头的指令,例如:
