centos 6.5 配置安装vnc

环境:

OS:Centos 6.5/6.9

 

1.安装桌面包(选择桌面安装的话，已经安装)
yum -y groupinstall Desktop
yum -y groupinstall "X Window System"

 

2.设置图形界面启动(需要重新启动)
/etc/inittab
修改为5 图形界面启动
id:5:initdefault:

或是不设置也可以通过startx启动图形界面

 

3.安装图形界面右键出现打开终端栏目
[root@newepidb ios]# mount CentOS-6.5-x86_64-bin-DVD1.iso -o loop /mnt
[root@newepidb ios]#yum -y install nautilus-open-terminal

 

安装vnc
1.检查是否已经安装了vnc-server
[root@newepidb ios]# rpm -q tigervnc tigervnc-server
package tigervnc is not installed
package tigervnc-server is not installed

 

2.安装vnc-server
yum install tigervnc-server

3.配置vnc-server

打开配置文件目录并编辑配置文件

[root@VM_0_11_centos ~]# vi /etc/sysconfig/vncservers[root@rac01 u01]# more /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 this URL:
# https://access.redhat.com/knowledge/solutions/7027

# Use "-nolisten tcp" to prevent X connections to your VNC server via TCP.

# 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:root 1:oracle 3:grid"
##VNCSERVERARGS[1]="-geometry 800x600 -nolisten tcp -localhost"
VNCSERVERSVNCSERVERARGS[1]="-geometry 1024x768 -alwaysshared"
VNCSERVERSVNCSERVERARGS[2]="-geometry 1024x768 -alwaysshared"
VNCSERVERSVNCSERVERARGS[3]="-geometry 1024x768 -alwaysshared"

 

 

 

 

 

4.输入命令启动vnc服务(root访问密码)
初始启动时需要配置远程用户连接vnc时输入的密码
[root@newepidb ios]# vncserver

You will require a password to access your desktops.

Password:
Verify:
xauth: (stdin):1: bad display name "newepidb:1" in "add" command

New 'newepidb:1 (root)' desktop is newepidb:1

Creating default startup script /root/.vnc/xstartup
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/newepidb:1.log

 

5.修改vnc远程连接的密码(oracle访问密码,可以与root设置的密码不一样)
su - oracle
[oracle@newepidb ~]$ vncpasswd
Password:
Verify:

 

su - grid
[oracle@newepidb ~]$ vncpasswd
Password:
Verify: 

 

 

6.重启动vncserver

杀掉之前启动的进程

vncserver -kill :1 ##kill与:之间有空格
vncserver -kill :2 ##kill与:之间有空格

service vncserver stop
service vncserver start

 

7.查看
[root@newepidb ios]# vncserver -list

TigerVNC server sessions:

X DISPLAY # PROCESS ID
:1 2536

我在centos6.9上安装该命令没有显示也可以正常使用

 

查看端口是否打开

[root@rac01 u01]# ss -nlp|grep 5901
LISTEN 0 5 *:5901 *:* users:(("Xvnc",5151,5))

 

8.关闭防火墙
[root@newepidb ios]#service iptables stop --命令关闭防火墙，但是系统重启后会开始
[root@newepidb ios]#chkconfig iptables off --关闭防火墙开机自启动
[root@newepidb ios]#chkconfig --list --查看开机情况

9.日常命令
service vncserver status
service vncserver restart
service vncserver stop
service vncserver start

vncserver -kill :1 ##kill与:之间有空格
vncserver -kill :2 ##kill与:之间有空格

9.设置屏幕保护(非root账号也可以设置)
System -> Preferences -> Screensaver。
如果需要取消屏幕保护的锁定功能，将Lock screen when screensaver is active前面的勾去掉就可以了

 

10.通过vnc :1进行连接(oracle账号)

192.168.56.66:1

 

grid账号

 192.168.56.66:3
