Paramiko是一个用于执行SSH命令的Python第三方库，使用该库可实现自动化运维的所有任务，如下是一些常用代码的封装方式，多数代码为半成品，只是敲代码时的备份副本防止丢失，仅供参考。
目前本人巡检百台设备完全无压力，如果要巡检过千台则需要多线程的支持，过万台则需要加入智能判断等。
实现命令执行: 直接使用过程化封装,执行CMD命令.

我们继续为上面的代码加上命令行，让其可以直接使用，这里需要遵循一定的格式规范，我们使用JSON解析数据，JSON格式如下.
{
"aix":
[
["192.168.1.1","root","123123"],
["192.168.1.1","root","2019"],
],
"suse":
[

],
"centos":
[
["192.168.1.1","root","123123"],

}

简单的使用命令：
远程CMD: python main.py --group=centos --cmd="free -h | grep -v 'total'"
判断存活: python main.py --group=centos --get="ping"
拉取磁盘：python main.py --group=suse --get="disk"
批量上传文件: python main.py --group=suse --src="/UploadFiles/2021-04-08/aaa">
由于我的设备少，所以没开多线程，担心开多线程对目标造成过大压力，也没啥必要。
番外： 另外我研究了一个主机分组的小工具，加上命令执行代码量才800行，实现了一个分组数据库，在这里记下使用方法。
默认运行进入一个交互式shell环境。
Init = 初始化json文件，ShowHostList=显示所有主机，ShowGroup=显示所有组，ShowAllGroup=显示所有主机包括组。
添加修改与删除记录，命令如下。
添加删除主机组。
通过UUID向主机组中添加或删除主机记录。
测试主机组连通性。

一口气升级7个大模型SaaS应用，百度智能云：突出一个“开箱即用” - 2024/12/24
这一波大模型产业落地浪潮里，不少企业其实处在 “干瞪眼“的状态。
一种情况是，很多大模型产品看得见却摸不着，在台上一个个遥遥领先——今天Sora技精四座，明天英伟达的机器人又赢得满堂彩，可是到了台下一问：啥时候能用上啊？答曰：遥遥无期。
另一种情况是，企业想用上大模型，却又难免瞻前顾后——既要考虑场景融合，又得兼顾安全性，还要考虑打通现有系统，再加上各种部署成本和繁琐的采购流程……最后只能拂袖：罢了，再等等吧。

稳了！魔兽国服回归的3条重磅消息！官宣时间再确认！
昨天有一位朋友在大神群里分享，自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址，com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后，确实是网易的网址，也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情，因为以前都没有出现这样的情况，现在突然提示跳转到国服战网的网址，是不是说明了简体中文客户端已经开始进行更新了呢？
