【一步一步走(1)】远程桌面软件VNC的安装与配置

最近在VPS上搭建Python Web环境,走了很多弯路,借此记下。

先说说购买的VPS(PhotonVPS),我可不是打广告,只是感觉这个VPS服务提供商还不错推荐给你大家,我之前也是体验过阿里云的,体验结果就不说了,反正不适合我。

使用系统是CentOS 64位,版本是 6.5,至于VNC的介绍,大家可以移步官网查看,下面就开始VNC的下载与配置了。 

1. 通过SSH远程连接VPS主机,Windows的小伙伴们可以下载SSH客户端进行连接。

ssh [用户名]@[IP地址]


2. 通过yum安装VNC


yum install tigervnc tigervnc-server -y

3. 安装桌面服务(VPS自带的系统一般都不会有桌面服务)

yum groupinstall -y "Desktop" "X Window System"

4. 安装完成后,执行vncserver,初始化密码

[root@sunth ~]# vncserver

You will require a password to access your desktops.

Password:
Verify:
xauth:  creating new authority file /root/.Xauthority
xauth: (stdin):1:  bad display name "sunth.localdomain:1" in "add" command

New 'sunth.localdomain:1 (root)' desktop is sunth.localdomain:1

Creating default startup script /root/.vnc/xstartup
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/sunth.localdomain:1.log

5. 修改刚刚生成的文件    /root/.vnc/xstartup

vi /root/.vnc/xstartup

将文件最后一行的 twn & 更改为 gnome-session &

更改后的文件:

#!/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" &
gnome-session &

6. 修改配置文件 /etc/sysconfig/vncservers

vi /etc/sysconfig/vncservers

在文件最后,加上显示配置与用户配置

VNCSERVERS="1:root"
VNCSERVERARGS[2]="-geometry 1024x768"

修改后的文件:

# 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:
# http://kbase.redhat.com/faq/docs/DOC-7028

# 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="1:root"
VNCSERVERARGS[2]="-geometry 1024x768"

7. 最后重启vnserver

[root@sunth ~]# service vncserver start
Starting VNC server: 1:root A VNC server is already running as :1
                                                           [FAILED]
[root@sunth ~]# service vncserver restart
Shutting down VNC server: 1:root                           [  OK  ]
Starting VNC server: 1:root xauth: (stdin):1:  bad display name "sunth.localdomain:1" in "add" command

New 'sunth.localdomain:1 (root)' desktop is sunth.localdomain:1

Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/sunth.localdomain:1.log

                                                           [  OK  ]

8. 在官网可以下载客户端,然后就可以远程桌面了,就写到这。
