首先，我这里用到的是阿里云服务器 centos7版本，win版客户端。
准备工作
centos7 服务器端文件：
https://github.com/rustdesk/rustdesk-server/releases/download/1.1.11-1/rustdesk-server-linux-amd64.zip
win版客户端安装包：https://github.com/rustdesk/rustdesk/releases/download/1.2.7/rustdesk-1.2.7-x86_64.msi
阿里云服务需要开放端口TCP：21115-21119，UDP需要开放21116端口。关闭防火墙，检查端口放行情况。
端口说明：
服务器：
hbbs - RustDesk ID 注册服务器
hbbr - RustDesk 中继服务器
开放端口：
默认情况下，hbbs 监听 21115(tcp) , 21116(tcp/udp) , 21118(tcp) ，hbbr 监听 21117(tcp) ， 21119(tcp) 。
TCP/21115 - hbbs 用作 NAT 类型测试
UDP/21116 - hbbs 用作 ID 注册与心跳服务
TCP/21116 - hbbs 用作 TCP 打洞与连接服务
TCP/21117 - hbbr 用作中继服务
TCP/21118/21119 - 网页客户端
云服务器操作
上传服务器文件到阿里云，我这里上传到root文件下进行解压的
unzip rustdesk-server-linux-amd64.zip
解压目录后会出现amd64文件，根据自己的需要可以进行修改为rustdesk。我这里没有进行修改，
[root@iZuf6hl7q5f09c9rycjhccZ amd64]# pwd
/root/amd64
进入到amd64文件夹
[root@iZuf6hl7q5f09c9rycjhccZ amd64]# ll
total 27596
-rwxr-xr-x 1 root root 9165824 May 24 18:49 hbbr
-rwxr-xr-x 1 root root 14353352 May 24 18:49 hbbs
-rwxr-xr-x 1 root root 4734896 May 24 18:49 rustdesk-utils
里面有三个文件。接下来我们要安装个软件，
安装screen，用于虚拟终端
yum -y install screen
准备启动hbbs、hbbr：
# 创建一个叫myHbbs的虚拟终端：
screen -R myHbbs
# 运行hbbs
./hbbs
出现如下图服务已正常启动
[root@iZuf6hl7q5f09c9rycjhccZ amd64]# ./hbbs

点击上方3个点进入设置。
状态变成就绪了。完成配置！
问题
连接出现KEY不匹配问题：
1.版本不匹配问题。
2.还是密钥问题，仔细检查密钥内容。
