安装jumpserver

一.jumpserver

Jumpserver是一款由Python编写开源的跳板机（堡垒机系统），实现了跳板机的应有的功能，基于ssh协议来管理服务器资源，客户端不需要安装jumpserver客户端软件程序。

* 堡垒机介绍

在特定网络环境中(如内网和外网)，为了保证公司网络中的服务器数据不受外界的和破坏，运用各种技术手段收集和监控公司服务器的状态，安全时间、以便集中报警，并且及时处理。
我们又把堡垒机叫做跳板机，简易的跳板机功能简单，主要核心功能是远程登陆服务器和日志审计比较优秀的开源软件jumpserver，功能齐全如：认证、授权、审计、自动化、资产管理（内网服务器资源分配）等。

* Jumpserver的特点

1.完全开源；
2.Python编写，易于二次开发
3.实现跳板机的基本功能、认证、授权、审计
4.集成了Ansiable，实现批量操作命令等
5.支持web终端
6.Bootstrap编写，界面美观
7.自动收集硬件信息
8.录像回放、命令搜索、实时监控

* Jump架构图

用户通过浏览器访问到nginx代理服务器页面，nginx服务器在jump架构中是作为一台代理服务器，用来代理jumpserver程序、coco程序、luna程序、guacamole程序的web页面，方便用户使用，如果不采用nginx做代理服务器的话，用户访问页面时比较麻烦（如coco程序需要用到8080端口、guncamole需要别的端口，使用起来不方便，而且后续的页面跳转有可能会导致not found），nginx调取luna程序设置终端采用ssh协议连接后端资产（后端服务器）。

Jumpserver组件说明

Jumpserver：jumpserver的管理后台
Coco：实现了ssh server 和 web终端的组件，提供ssh和websocket接口
Luna：是web Terminal 的前端（用来展示给用户和与用户进行交互）前端页面都是由该项目完成的
Guacamole：apache的跳板机项目，jumpserver使用其组件实现RDP（远程桌面）功，能，jumpserver在guacamole中添加额外插件，不修改其本身，实现调用

二.安装jumpserver

下载软件包

安装依赖环境：python3.6以上版本后端数据库 redis

修改字符集，支持中文字符

[[email protected] ~]# localedef -c -f UTF-8 -i zh_CN zh_CN.UTF-8
// -c 强制执行  -f 指定设置的字符集   -i  从那个源
[[email protected] ~]# export LC_ALL=zh_CN.UTF-8
// 将字符集设置成环境变量
[[email protected] ~]# echo ‘LANG="zh_CN.UTF-8"‘ > /etc/locale.conf
// 加入到字符配置文件
