编译安装

tar -xvf xrdp-0.9.11.tar.gz
cd xrdp-0.9.11
./bootstrap
./configure
make
make install

配置自启动

cp /etc/xrdp/xrdp.sh /etc/init.d/xrdp.sh;echo '/etc/init.d/xrdp.sh start' >>/etc/rc.local;chmod +x /etc/rc.d/rc.local;/etc/init.d/xrdp.sh start

修改配置文件使用Xvnc

vi /etc/xrdp/xrdp.ini
#[Xorg]
#name=Xorg
#lib=libxup.so
#username=ask
#password=ask
#ip=127.0.0.1
#port=-1
#code=20

[Xvnc]
name=Xvnc
lib=libvnc.so
username=ask
password=ask
ip=127.0.0.1
port=-1

如果图形颜色异常，可以修改如下数值

xserverbpp=24
#delay_ms=2000
