centos 开启VNC

it2022-05-06  0

安装软件包(有yum源安装的,不采用源码安装)

yum -y install vnc vnc-server

安装成功后,配置如下:

[root@localhost ~]# vncserver #设置 VNC密码,输入:(在某用户下输入则登陆用户就是它,如果su imiss切换到imiss用户,输入vncserver则启动的是另一个桌面,同样要设置密码,以后在该账户下启动的vncserver登陆就需要在此用户下设置的密码了。) You will require a password to access your desktops. Password: Password must be at least 6 characters - try again Password: Verify: 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 ~]# vncpasswd Password: Password must be at least 6 characters - try again Password: Verify: [root@localhost ~]#

修改配置文件:

vim ~/.vnc/xstartup (最后两行)

#xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" & #twm & gnome-session &

vim  /etc/sysconfig/vncservers  (最后两行)

# VNCSERVERS="2:myusername" # VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -localhost" VNCSERVERS="1:root" VNCSERVERARGS[1]="-geometry 800x600"

vi /etc/sysconfig/iptables (配置防火墙)

-A INPUT -m state --state NEW -m tcp -p tcp --dport 5901 -j ACCEPT -A INPUT -m state --state NEW -m tcp -p tcp --dport 5902 -j ACCEPT -A INPUT -m state --state NEW -m tcp -p tcp --dport 5903 -j ACCEPT#VNC server 监听的端口从 5900 开始,display:1 的监听 5901,display:2 监听 5902,以此类推。CentOS 的防火墙缺省是不允许连接这些端口的,所以需要使用下面的步骤打开防火墙(需要 root 权限):

 

[root@localhost ~]# service iptables restart iptables: Setting chains to policy ACCEPT: nat mangle filte[ OK ] iptables: Flushing firewall rules: [ OK ] iptables: Unloading modules: [ OK ] iptables: Applying firewall rules: [ OK ]

启动服务

[root@localhost ~]# chkconfig vncserver on [root@localhost ~]# service vncserver start Starting VNC server: 2:root New 'localhost.localdomain:2 (root)' desktop is localhost.localdomain:2 Starting applications specified in /root/.vnc/xstartup Log file is /root/.vnc/localhost.localdomain:2.log [ OK ] [root@localhost ~]#

关闭vnc

vncserver -kill :2 #注意kill后面要有一个空格

连接
