redhat下安装realvnc

#linux #vnc

###今天安装了realvnc,使用的系统是64位redhat。 在这里写下安装的步骤,供大家参考。

  • 1、从官网下载源码包,www.realvnc.com。在这里选择相应的源码包进行下载。我下载的是VNC-5.2.2-Linux-x64-ANY.tar.gz。

  • 2、解压该源码包,使用命令:

    tar -zxvf VNC-5.2.2-Linux-x64-ANY.tar.gz

  • 3、进入到刚解压到的安装目录(用cd VNC-5.2.2-Linux-x64/ 命令),使用如下的命令进行安装:

    ./vncinstall /usr/local/bin/

  • 4、运行命令vnserver,可能会出现如下的错误:

      VNC(R) Server 5.2.2 (r7974) 64-bit (Nov 28 2014 14:43:49)

      Error: No license keys found.
      Run vnclicense to apply a license key. [NoLicense]
    

    这里的错误是说,缺少通行证,可以在网上随便找个。这里我使用的是:WHJRK-UXY7V-Q34M9-CZU8L-8KGFA。 使用如下的命令进行通行证的添加:

      vnclicense -add WHJRK-UXY7V-Q34M9-CZU8L-8KGFA
    
  • 5、添加完通行证后,再次执行: vncserver,可能会出现如下问题:

      VNC(R) Server 5.2.2 (r7974) 64-bit (Nov 28 2014 14:43:49)

      xauth: (argv):1:  bad display name "linux-o70w:2" in "add" command
      Error: could not run xauth
    

    主要是下面两句,在网上找了很久,都说在网上查资料发现这个错误是由于/etc/hosts文件中缺少配置造成的,应该在/etc/hosts文件中添加一句127.0.0.1 localhost的语句在最后。但当我打开该文件时,发现里面已经有这句了。通过向实验室的另一个人请教,他告诉了我如下可行方法。 注意到上述错误中,我设置成红色的部分(linux-o70w:2),这里有linux-o70w,将linux-o70w添加到//etc/hosts中,方法如下: 打开/etc/hosts文件,在其中添加下面这句,根据你的错误对linux-o70w进行相应的修改: 127.0.0.1 linux-o70w 下面是我的/etc/hosts的文件内容,我只在里面加了一行:127.0.0.1 linux-o70w

      #
      # hosts         This file describes a number of hostname-to-address
      #               mappings for the TCP/IP subsystem.  It is mostly
      #               used at boot time, when no name servers are running.
      #               On small systems, this file can be used instead of a
      #               "named" name server.

  • 6、再次输入vncserver命令,出现以下类似输出说明是对的:

      VNC(R) Server 5.2.2 (r7974) 64-bit (Nov 28 2014 14:43:49)

      If a desktop environment fails to load for this virtual desktop, please see:

      Log file is /root/.vnc/linux-o70w:2.log
      New desktop is linux-o70w:2 (211.69.192.12:2)
    

    注意红色部分,它是进行远程登录时所会用到的IP和端口。

  • 7、使用vncviewert,连接到远程控制服务器。 假设,另外一台电脑已经装有vncviewet,上述安装vnc的方法,会同时安装vncserver和vncviewer。使用下面的命令连接远程的电脑: 命令行输入:vncviewer 在弹出的 窗口:VNC Server一栏中输入上述红色部分:211.69.192.12:2 单击connect,在弹出框中输入远程主机的用户名和密码即可。
