xrdp 是一个开源远程桌面协议服务器，它允许我们从 Windows 计算机到 Linux 服务器进行 RDP;它能够接受来自 rdesktop、freerdp 和远程桌面客户端的连接。
1.安装Redhat扩展更新源，软件为epel-relase
rpm -Uvh https://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-12.noarch.rpm
2.接着安装nux-dextop
rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-1.el7.nux.noarch.rpm
3.想要安装xrdp,就要新建一个安装源
[root@localhost ~]# vi /etc/yum.repos.d/xrdp.repo
[root@localhost ~]# tail /etc/yum.repos.d/xrdp.repo
[xrdp]
name=xrdp
baseurl=http://li.nux.ro/download/nux/dextop/el7/x86_64/
enabled=1
gpgcheck=0

遇到的问题1：新建本地安装源后执行yum makecache时报错
[root@localhost yum.repos.d]# yum makecache
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager
This system is not registered with an entitlement server. You can use subscription-manager to register.
Existing lock /var/run/yum.pid: another copy is running as pid 18858.
Another app is currently holding the yum lock; waiting for it to exit...
The other application is: PackageKit

State : Sleeping, pid: 18858
——报错显示yum在锁定状态中。 /var/run/yum.pid打开看了，只是一个数，也可能是系统自动升级正在运行，所以yum被锁定了。
less /var/run/yum.pid
——问题1解决方法·：强行关掉yum进程
m -rf 18858
rm -rf /var/run/yum.pid

再次yum makecache又出现了问题2：报错显示没有挂载光驱
[root@localhost run]# yum makecache

file:///media/repodata/repomd.xml: [Errno 14] curl#37 - "Couldn't open file /media/repodata/repomd.xml"
Trying other mirror.
One of the configured repositories failed (local),
and yum doesn't have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work "fix" this:
1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).
3. Run the command with the repository temporarily disabled
yum --disablerepo=local ...
4. Disable the repository permanently, so yum won't use it by default. Yum
will then just ignore the repository until you permanently enable it
again or use --enablerepo for temporary usage:
yum-config-manager --disable local
or
subscription-manager repos --disable=local
5. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager --save --setopt=local.skip_if_unavailable=true
failure: repodata/repomd.xml from local: [Errno 256] No more mirrors to try.
file:///media/repodata/repomd.xml: [Errno 14] curl#37 - "Couldn't open file /media/repodata/repomd.xml"
——问题2解决方法·：配置本地yum文件，重新挂载
[root@localhost etc]# cd yum.repos.d/
[root@localhost yum.repos.d]# ls
epel.repo epel-testing.repo local.repo nux-dextop.repo packagekit-media.repo redhat.repo xrdp.repo
[root@localhost yum.repos.d]# vi local.repo
[root@localhost yum.repos.d]# mount /dev/cdrom /media
mount: /dev/sr0 is write-protected, mounting read-only
4.执行yum makecache，就是把服务器的包信息下载到本地电脑缓存起来
yum makecache
5.安装xrdp成功
[root@localhost yum.repos.d]# yum install xrdp
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager
This system is not registered with an entitlement server. You can use subscription-manager to register.

6.把端口3389加入到防火墙规则
这一步在图形界面下操作容易一些
3389
修改配置后，需要用systemctl重启一下firewalld服务
systemctl stop firewalld
systemctl start firewalld
7.启动xrdp服务，可以在Windows上远程登录到虚拟机了
[root@localhost ~]# systemctl enable xrdp.service
Created symlink from /etc/systemd/system/multi-user.target.wants/xrdp.service to /usr/lib/systemd/system/xrdp.service.
[root@localhost ~]# systemctl start xrdp
[root@localhost ~]#
在windows运行中输入mstsc
mstsc
输入用户名和密码就可以登入
登录界面
完成
