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 0.0.0.0:5801                0.0.0.0:*                   LISTEN
tcp        0      0 0.0.0.0:5901                0.0.0.0:*                   LISTEN
tcp        0      0 0.0.0.0:111                 0.0.0.0:*                   LISTEN
tcp        0      0 0.0.0.0:6001                0.0.0.0:*                   LISTEN
tcp        0      0 0.0.0.0:724                 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。
