使用windows调用Linux远程桌面

  一、安装所需要的软件
  yum install -y xrdp
  yum install -y vnc*
  chkconfig xrdp on
  chkconfig vncserver on
  二、修改配置
  a添加用户:useradd herry
  b.设置vnc验证密码:su - herry
  :vncpasswd
  c.修改配置:
  1.# vim /etc/sysconfig/vncservers
  # The VNCSERVERS variable is a list of display:user pairs.
  #
  # Uncomment the lines below to start a VNC server on display :2
  # as my 'myusername' (adjust this to your own).You will also
  # need to set a VNC password; run 'man vncpasswd' to see how
  # to do that.
  #
  # DO NOT RUN THIS SERVICE if your local area network is
  # untrusted!For a secure way of using VNC, see this URL:
  # https://access.redhat.com/knowledge/solutions/7027
  # Use "-nolisten tcp" to prevent X connections to your VNC server via TCP.
  # Use "-localhost" to prevent remote VNC clients connecting except when
  # doing so through a secure tunnel.See the "-via" option in the
  # `man vncviewer' manual page.
  # VNCSERVERS="2:myusername"
  # VNCSERVERARGS="-geometry 800x600 -nolisten tcp -localhost"
  VNCSERVERS="2:herry"
  VNCSERVERARGS="-geometry 1280x720 -nolisten tcp -localhost"
  2.在防火墙中加入:
  vim /etc/sysconfig/iptables
  -A INPUT -m state --state NEW -m tcp -p tcp --dport 3389 -j ACCEPT
  重启防火墙:service iptabels restart
  三、一般服务器是没有桌面环境的,需要安装中文界面
  yum groupinstall "Desktop"
  yum groupinstall "X Window System"
  yum groupinstall "Chinese Support"
  重启
  四、使用windows连接linux远程桌面
  a.windows上敲mstsc
  b.输入liunx服务器Ip地址,和验证用户名和密码(herry   l426844@)
  五   报错处理:出现xrdp_mm_process_login_response: login failed
  问题原因:远程桌面没有正确关闭,虽然在windows 系统关闭远程桌面连接,但是在里linux上的进程还在运行,导致连接数量达到上限,出现问题。
  # vim /etc/xrdp/sesman.ini
  
  ListenAddress=127.0.0.1
  ListenPort=3350
  EnableUserWindowManager=1
  UserWindowManager=startwm.sh
  DefaultWindowManager=startwm.sh
  
  AllowRootLogin=1
  MaxLoginRetry=4
  TerminalServerUsers=tsusers
  TerminalServerAdmins=tsadmins
  
  X11DisplayOffset=10
  MaxSessions=100
  KillDisconnected=1
  IdleTimeLimit=0
  DisconnectedTimeLimit=0
  
  LogFile=/var/log/xrdp-sesman.log
  LogLevel=DEBUG
  EnableSyslog=0
  SyslogLevel=DEBUG
  
  param1=-bs
  param2=-nolisten
  param3=tcp
  
  param1=-bs
  param2=-nolisten
  param3=tcp
  param4=-localhost
  可以修改会话设置:将最大会话限制该大MaxSessions=50
  将KillDisconnected=1;则每次断开连接时,linux都会关闭会话进程。
  然后重启/etc/init.d/xrdp restart    就可解决问题
  六.如果打开后,出现只有背景的情况
  下面我们需要修改vnc启动文件,使用命令:
  vi ~/.vnc/xstartup
  打开后如下图所示

  我们需要把上图中 “x-window-manager &” 这一行注释掉,然后在下面加入一行 “gnome-session &” ,或者是 “startkde &” ,分别表示要启用 GNOME 桌面或 KDE 桌面。以 GNOME 桌面为例,修改后如下图所示:
  具体修改步骤:打开文件后,点击 insert 按钮,这时就可以输入了,在 “x-window-manager &” 前加 “#”,然后回车输入 “gnome-session &”,然后点击 “Esc ” 退出编辑模式,输入 “:wq!”保存修改即可)

  我的机器:
  #vi ~/.vnc/xstartup
  #!/bin/sh
  [ -r /etc/sysconfig/i18n ] && . /etc/sysconfig/i18n
  export LANG
  export SYSFONT
  vncconfig -iconic &
  unset SESSION_MANAGER
  unset DBUS_SESSION_BUS_ADDRESS
  OS=`uname -s`
  if [ $OS = 'Linux' ]; then
  case "$WINDOWMANAGER" in
  *gnome*)
  if [ -e /etc/SuSE-release ]; then
  PATH=$PATH:/opt/gnome/bin
  export PATH
  fi
  ;;
  esac
  fi
  if [ -x /etc/X11/xinit/xinitrc ]; then
  exec /etc/X11/xinit/xinitrc
  fi
  if [ -f /etc/X11/xinit/xinitrc ]; then
  exec sh /etc/X11/xinit/xinitrc
  fi
  [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
  xsetroot -solid grey
  xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
  twm &
  七。登陆成功
