RedHat VNC 配置

男娘i 2022-08-14 03:49 204阅读 0赞

**1.查看是否已经安装VNC：**  
\[root@localhost ~\]\# rpm -q vnc vnc-server  
vnc-4.1.2-14.el5\_3.1

vnc-server-4.1.2-14.el5\_3.1

版本问题，卸载安装：

\[root@localhost ~\]\# rpm -e vnc-server-4.1.2-14.el5\_3.1

**2.把用户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="1:root"          \#1为桌面号，客户端远程使用需要添加上  
VNCSERVERARGS\[2\]="-geometry 800x600 -nolisten tcp -nohttpd -localhost"  
  
**3.防火墙端口设置：在使用防火墙的情况下来连接到一个远程系统,需要打开端口5901，并重启iptables服务。**  
\[root@localhost ~\]\# 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 ESTABLISHED,RELATED -j ACCEPT  
\-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 21 -j ACCEPT  
\-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT  
\-A RH-Firewall-1-INPUT -m state --state NEW -m udp -p udp --dport 137 -j ACCEPT  
\-A RH-Firewall-1-INPUT -m state --state NEW -m udp -p udp --dport 138 -j ACCEPT  
\-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 139 -j ACCEPT  
\-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 445 -j ACCEPT  
\-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 23 -j ACCEPT  
\-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT  
\-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 5901 -j ACCEPT  
\-A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited  
COMMIT

重启iptables服务：\[root@localhost ~\]\# /sbin/service iptables restart

**4.启动vncserver：**  
\[root@localhost ~\]\# 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.设置图形界面登录，并重启：**  
\[root@localhost ~\]\# vi /root/.vnc/xstartup  
\#!/bin/sh  
\# Uncomment the following two lines for normal desktop:  
unset SESSION\_MANAGER \#去掉注释符号‘\#’  
exec /etc/X11/xinit/xinitrc        \#去掉注释符号‘\#’  
\[ -x /etc/vnc/xstartup \] && 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 &               \#注释掉  
gnome-session & \#新增

重启vncserver：\[root@localhost ~\]\# service vncserver restart

http://IP:port的方式来WEB登录比如说  
http://192.168.1.100:5801,也可以在vncviewer里用192.168.1.100:1这种来登录。
