近期在VPS上搭建Python Web环境。走了非常多弯路，借此记下。
先说说购买的VPS（PhotonVPS），我可不是打广告。仅仅是感觉这个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，版本号是 6.5。至于VNC的介绍，大家能够移步官网查看，以下就開始VNC的下载与配置了。
1. 通过SSH远程连接VPS主机，Windows的小伙伴们能够下载SSHclient进行连接。
ssh [username]@[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. 安装完毕后。运行vncserver。初始化password
[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. 改动刚刚生成的文件 /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. 改动配置文件 /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"
改动后的文件：
# 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. 最后重新启动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. 在官网能够下载client，然后就能够远程桌面了，就写到这。
