根据不同的项目网络场景环境，实现远程服务器的方式有很多：

第3方需要接入中心服务器中转实现远程连接的：如TeamViewer、Todesk、Anydesk、RustDesk、向日葵等常见方案。
去中心化的：如Mstsc,vnc，互联网连接时需要映射到内网的主机ip和远程端口，内网可以直接连接。另外，TeamViewer、Anydesk、RustDesk也支持内网连接。

xrdp安装

xrdp优点：

远程画面质量、连接响应速度明显比vnc好，
在服务配置上比tigervnc-server配置和管理方便。
登陆用户密码与ssh登陆一致。
在windows电脑远程linux主机时不需要额外客户端。

下面详细介绍xrdp服务安装与软件包依赖处理过程。

centos7.9安装xrdp

解决依赖

xrdp软件包是epel源中的软件包，需要使用到epel源

依赖

如下的依赖输出可以大概了解到xrdp¹是需要epel源中的imlib2软件包，xrdp本身也是epel源中的软件包，其它的都是base源中提供的。服务器有互联网络连接时配置上epel源直接yum 安装即可，yum会自动处理案卷依赖。如果没有网络时，需要下载最新的centos7 iso镜像并配置本地yum源，同时在有网的环境下通过如下方式获取xrdp、imlib2包（epel源不提供iso下载，而且镜像克隆epel源占用的磁盘空间成本太高。）：

yumdownloader下载xrdp、imlib2软件
通过软件包搜索网站：https://pkgs.org/ 搜索下载，

然后yum localinstall
