Redhat下VNC SERVER的配置

1、启动VNC SERVER

输入vncserver，第一次启动会要求输入验证密码，完成后，VNC SERVER就启动了

[root@localhost ~]# vncserver

You will require a password to access your desktops.

Password:
//输入密码

Verify:
//再次输入密码

xauth: creating new authority file /root/.Xauthority

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

[root@localhost ~]#

2、编辑.vnc/xstartup

使用VI打开xstartup文件，如下：

[root@localhost /]# cd /root/.vnc

[root@localhost .vnc]# vi xstartup

删除全部内容，然后添加如下内容：

unset SESSION_MANAGER

exec /etc/X11/xinit/xinitrc

3、重启动VNC SERVER

[root@localhost ~]# vncserver -kill :1

Killing Xvnc process ID 21198

[root@localhost ~]# vncserver

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

[root@localhost ~]#

4、查看VNC的监听端口

如下，VNC用到了三个端口：5801、5901、6001。

[root@localhost /]# netstat -nat

Active Internet connections (servers and established)

Proto Recv-Q Send-Q Local Address Foreign Address State

tcp 0 0 127.0.0.1:2208 0.0.0.0:* LISTEN

tcp 0 0 127.0.0.1:631 0.0.0.0:* LISTEN

tcp 0 0 127.0.0.1:2207 0.0.0.0:* LISTEN

tcp 0 0 172.200.102.3:5901 181.181.181.51:1669 ESTABLISHED

tcp 0 0 :::6001 :::* LISTEN

tcp 0 0 :::22 :::* LISTEN

tcp 0 1364 ::ffff:172.200.102.3:22 ::ffff:181.181.181.51:1599 ESTABLISHED

[root@localhost /]#

5、在防火墙上打开VNC用到的上面三个端口

[root@localhost /]# cd /etc/sysconfig

[root@localhost sysconfig]# vi iptables

添加如下三行：

-A RH-Firewall-1-INPUT -m state –state NEW -m tcp -p tcp –dport 5801 -j ACCEPT

-A RH-Firewall-1-INPUT -m state –state NEW -m tcp -p tcp –dport 5901 -j ACCEPT

-A RH-Firewall-1-INPUT -m state –state NEW -m tcp -p tcp –dport 6001 -j ACCEPT

重记动IPTABLES

[root@localhost sysconfig]#
/etc/rc.d/init.d/iptables restart

Flushing firewall rules: [ OK ]

Setting chains to policy ACCEPT: filter [ OK ]

Unloading iptables modules: [ OK ]

Applying iptables firewall rules: [ OK ]

Loading additional iptables modules: ip_conntrack_netbios_ns ip_conntrack_ftp [ OK ]

[root@localhost sysconfig]#

6、使用VNC VIEW连接VNC SERVER

下载VNC VIEW，运行，然后输入IP:端口号，输入刚才设定的密码，进入REDHAT桌面。
