編輯 xrdp.repo
vi /etc/yum.repos.d/xrdp.repo

[xrdp]
name=xrdp
baseurl=http://li.nux.ro/download/nux/dextop/el7/x86_64/
enabled=1
gpgcheck=0


安裝 Installation:

yum -y install pixman libXfont xrdp tigervnc-server

以下兩個動作 很重要：
chcon --type=bin_t /usr/sbin/xrdp
chcon --type=bin_t /usr/sbin/xrdp-sesman

如果失敗了，先下以下指令
ls -Z /usr/sbin
找到 xrdp 等檔案，發現有 ? 符號
以下列指令修改屬性，例如：
chcon -h system_u:object_r:bin_t:s0 /usr/sbin/xrdp
chcon -h system_u:object_r:bin_t:s0 /usr/sbin/xrdp-chansrv
chcon -h system_u:object_r:bin_t:s0 /usr/sbin/xrdp-sesman
chcon -h system_u:object_r:bin_t:s0 /usr/sbin/xrdp-sessvc

然後再檢查一次，
ls -Z /usr/sbin
直到都沒有 ? 符號，成功之後，再回頭下剛剛那兩個指令

接下來，編輯 vi /etc/xrdp/sesman.ini
找到 [Xnvc] 這一段，加入以下：

param7=-depth
param8=24

確定 param 數字號碼是連續的。


要修改 xrdp 對外服務的 PORT 號碼則
vi /etc/xrdp/xrdp.ini
改掉 3389 的值

檔案最尾巴加入以下:
[xrdp8]
name=Reconnect
lib=libvnc.so
username=ask
password=ask
ip=127.0.0.1
port=5910



啟動服務：
systemctl stop firewalld
systemctl disable firewalld
systemctl enable xrdp.service
systemctl start xrdp.service



防火牆如果需要打洞3389
firewall-cmd --permanent --zone=public --add-port=3389/tcp
firewall-cmd --reload

Install xrdp Remote Desktop to CentOS 6 / RHEL 6

Source:http://www.itzgeek.com/how-tos/linux/centos-how-tos/install-xrdp-remote-desktop-to-centos-6-rhel-6.html#axzz3R9CgCVo3

Prerequisites:

Install EPEL repository on CentOS 6.

32 Bit

#rpm -UvH http://mirror01.idc.hinet.net/EPEL/6/i386/epel-release-6-8.noarch.rpm # rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

64 Bit

#rpm -UvH http://mirror01.idc.hinet.net/EPEL/6/x86_64/epel-release-6-8.noarch.rpm # rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

Installation:

Issue the following command to install xrdp

# yum -y install xrdp tigervnc-server

You will get the following output, make sure you are getting package from the newly created repository.

Installed:   tigervnc-server.x86_64 0:1.1.0-8.el6_5      xrdp.x86_64 0:0.5.0-0.13.el6   Dependency Installed:   libXmu.x86_64 0:1.1.1-2.el6   xorg-x11-fonts-misc.noarch 0:7.2-9.1.el6   xorg-x11-xauth.x86_64 1:1.0.2-7.1.el6

Once it is installed, lets start the xrdp service.

# service xrdp start

xrdp will listen on 3389, lets confirm this by issuing following command.

# netstat -antup | grep xrdp tcp        0      0 127.0.0.1:3350              0.0.0.0:*                   LISTEN      11299/xrdp-sesman tcp        0      0 0.0.0.0:3389                0.0.0.0:*                   LISTEN      11295/xrdp

By default, services wont auto start after system reboot. Issue the following command to enable the service at system start up.

# chkconfig xrdp on # chkconfig vncserver on
