xrdp是Microsoft远程桌面协议(RDP)服务的开源实现。它允许您以图形方式控制远程计算机。使用xrdp,您可以登录到与Microsoft远程桌面协议(RDP)相同的远程计算机。本教程描述如何在CentOS7系统上安装xrdp(远程桌面),安装之前需要检查服务器网络及yum源正常。
安装软件包
在CentOS7中,有多种桌面环境可选:
[root@centos7 ~]# yum grouplist|grep -i desktop
Cinnamon Desktop
MATE Desktop
GNOME Desktop
General Purpose Desktop
KDE Desktop
LXQt Desktop
[root@centos7 ~]#
以root用户身份运行以下命令在远程服务器上安装Gnome:
[root@centos7 ~]# yum -y groupinstall "GNOME Desktop"
Loaded plugins: fastestmirror, langpacks

[root@centos7 ~]#
安装xrdp软件包:
[root@centos7 ~]# yum -y install xrdp
配置并启动xrdp服务
安装完成后,您需要启动xrdp服务并在系统启动时启用它:
[root@centos7 ~]# systemctl enable xrdp --now
Created symlink from /etc/systemd/system/multi-user.target.wants/xrdp.service to /usr/lib/systemd/system/xrdp.service.
[root@centos7 ~]#
检查xrdp服务状态
查看xrdp服务是否运行,关注“Active: active (running)”
字段输出 :
[root@centos7 ~]# systemctl status xrdp
* xrdp.service - xrdp daemon
Loaded: loaded (/usr/lib/systemd/system/xrdp.service; enabled; vendor preset: disabled)

[root@centos7 ~]#
查看xrdp服务监听状态,有3350和3389两个端口,其中3350监听内网回环地址127.0.0.1,3389监听0.0.0.0。
[root@centos7 ~]# netstat -ntpl|grep xrdp
tcp 0 0 127.0.0.1:3350 0.0.0.0:* LISTEN 26960/xrdp-sesman
tcp 0 0 0.0.0.0:3389 0.0.0.0:* LISTEN 26961/xrdp
[root@centos7 ~]#
登录远程桌面服务器
通过以上设置,就可以使用windows远程桌面工具(mstsc)像登录windows远程桌面一样远程登录centos7桌面服务了。
注意事项:如果通过以上设置依旧不能登录centos7远程桌面,请注意检查您当前服务器的iptables规则及其他安全策略。
