RedHat5.4 VNC 配置
1.查看VNC是否已經安裝：
[root@localhost ~]# rpm -q vnc vnc-server
package vnc is not installed
vnc-server-4.1.2-14.el5_3.1
2.把用戶名加入到配置文件中：
[root@localhost ~]# vi /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
# <URL:http://www.uk.research.att.com/archive/vnc/sshvnc.html>.
# Use "-nolisten tcp" to prevent X connections to your VNC server via TCP.
# Use "-nohttpd" to prevent web-based VNC clients connecting.
# 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[2]="-geometry 800x600 -nolisten tcp -nohttpd -localhost"
VNCSERVERS="1:root" #新增部分
3.防火牆端口設置
在使用防火牆的情況下來連接到一個遠程系統,需要打開端口5901，然後重啓iptables服務。
[root@localhost ~]# vi /etc/sysconfig/iptables
# Firewall configuration written by system-config-securitylevel
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
:RH-Firewall-1-INPUT - [0:0]
-A INPUT -j RH-Firewall-1-INPUT
-A FORWARD -j RH-Firewall-1-INPUT
-A RH-Firewall-1-INPUT -i lo -j ACCEPT
-A RH-Firewall-1-INPUT -p icmp --icmp-type any -j ACCEPT
-A RH-Firewall-1-INPUT -p 50 -j ACCEPT
-A RH-Firewall-1-INPUT -p 51 -j ACCEPT
-A RH-Firewall-1-INPUT -p udp --dport 5353 -d 224.0.0.251 -j ACCEPT
-A RH-Firewall-1-INPUT -p udp -m udp --dport 631 -j ACCEPT
-A RH-Firewall-1-INPUT -p tcp -m tcp --dport 631 -j ACCEPT

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 5901 -j ACCEPT #新增部分
-A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited
COMMIT
4.重啓iptables服務
[root@localhost ~]# /sbin/service iptables restart
清除防火牆規則： [確定]
把 chains 設置爲 ACCEPT 策略：nat filter [確定]
正在卸載 Iiptables 模塊： [確定]
應用 iptables 防火牆規則： [確定]
載入額外 iptables 模塊：ip_conntrack_netbios_ns ip_conntrac[確定]
5.啓動vncserver，這時候通過VNC Viewer只能看到終端窗口
[root@localhost ~]# vncserver
You will require a password to access your desktops.
Password: #123456
Verify: #123456
New 'localhost.localdomain:1 (root)' desktop is localhost.localdomain:1
Creating default startup script /root/.vnc/xstartup
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/localhost.localdomain:1.log
5.設置圖形界面登錄
[root@localhost ~]# vi /root/.vnc/xstartup
#!/bin/sh
# Uncomment the following two lines for normal desktop:
unset SESSION_MANAGER #去掉註釋符號‘#’
exec /etc/X11/xinit/xinitrc #去掉註釋符號‘#’
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
#twm & #註釋掉
gnome-session & #新增
6.重啓vncserver
[root@localhost ~]# service vncserver restart
關閉 VNC 服務器：1:root [確定]
啓動 VNC 服務器：1:root xauth: creating new authority file /root/.Xauthority
New 'localhost.localdomain:1 (root)' desktop is localhost.localdomain:1
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/localhost.localdomain:1.log
[確定]
[root@localhost ~]#
7.這時再通過客戶端就可以登錄圖形界面了
