批量下执行命令,上传下载文件的脚本,执行命令下载文件


 前言:

    一家中型公司,全国各省近2000台服务器竟然没有一个运维平台,我也是醉了,每天挨个挨个登陆机器,管理机器真是操蛋,为此自己工作之余借助paramiko模块写了一个批量执行命令,上传下载文件的脚本,写的代码烂到哭,但最起码还能凑合着用吧。

    使用环境是python2.6-2.7,其中要在当前目录下生成一个ssh_login.txt文件,它是用户保存登陆用户名和密码以及主机名的文件,格式如下:

主机名,端口,用户名,验证方式是公私钥认证还是密码验证,密码,  #每行以逗号结尾,不允许有空行,
172.168.19.25,22,root,password,xxxxx, 172.168.19.26,22,root,password,xxxxx,

 

    脚本源码如下,使用方法是:

     python 脚本名  [ -c command] -m put/down -l local_file_path -r remote_file_path

             -c 的话是批量执行命令,此时上传下载功能将不使用。

             -m是指定模式,是下载还是上传

             -l 是指定本地文件路径

             -r 是远端文件路径,必须是绝对路径,要写出文件名来。

              -h 是捕获帮助信息。

    比如我现在要批量执行命令 --  python xxx.py  -c "uptime; df -hT"

    比如我现在要批量上传文件 -- python xxx.py -m put -l /tmp/123.txt -r /tmp/123.txt

    比如我现在要批量下载文件 -- python xxx.py -m down -l /tmp/123.txt -r /tmp/123.txt

        这里要注意的是,如果是下载模式,那么下载后的文件格式是这样的   文件名_主机ip

           如果运行出错了,那么会在当前目录下生成一个error.log,这里记录了如主机登陆不上或者是无法连接等错误信息。

    默认启动10个进程,粘贴复制的时候可能把缩进对齐给弄乱了,如果有疑问,可以联系我的email:18500777133@sina.cn
