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

#VNCSERVERS="2:myusername"
VNCSERVERS="1:root 2:grid 3:oracle"
VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -localhost"

VNCSERVERS 是用来设定可以使用VNC的服务器账号，可以设定多个，例如上面root、grid、oracle，但是中间要用空格隔开。使用VNCVIEWER登录时，10.2.21.10:1表示是以root账号登录

重启服务：

[root@dfmc-dbaasp-01 ~]# service vncserver start
正在启动 VNC 服务器：1:root A VNC server is already running as :1
2:grid 
You will require a password to access your desktops.

getpassword error: Inappropriate ioctl for device
Password:3:oracle 
You will require a password to access your desktops.

getpassword error: Inappropriate ioctl for device

[root@dfmc-dbaasp-01 ~]# 

设置vnc密码

[root@dfmc-dbaasp-01 ~]# vncpasswd
Password:
Verify:
[root@dfmc-dbaasp-01 ~]#su - grid
[root@dfmc-dbaasp-01 ~]# vncpasswd
Password:
Verify:
[root@dfmc-dbaasp-01 ~]#su - oracle
[root@dfmc-dbaasp-01 ~]# vncpasswd

配置xstartup文件
如下所示，将下面的部分注释取消
#!/bin/sh
# Uncomment the following two lines for normal desktop:
unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc



[root@dfmc-dbaasp-01 ~]# service vncserver restart
