sentos 上安装vnc图形界面

一、安装gnome图形化桌面

CentOS 6.3 64位

#yum groupinstall -y "X Window System"

#yum groupinstall -y "Desktop"

#yum groupinstall -y "Chinese Support"

二、安装vncserver并配置

1.安装vncserver

#yum install -y tigervnc-server

2.配置vncserver

1).配置为开机自启动

#chkconfig --level 345 vncserver on

2).配置vnc密码

#vncserver

You will require a password to access your desktop.

Password:

Verify:

3).配置为使用gnome桌面

修改 /root/.vnc/xstartup文件，把最后的 twm & 删掉加上 gnome-session &。

# vi /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:
# http://kbase.redhat.com/faq/docs/DOC-7028

# 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="1:root"
VNCSERVERARGS[1]="-geometry 1200x800"
# VNCSERVERS="2:myusername"
# VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -localhost"

4).配置vncserver启动后监听端口和环境参数

修改/etc/sysconfig/vncservers 文件添加以下内容

# vi /etc/sysconfig/vncservers

VNCSERVERS="1:root"

# 桌面号:用户监听 590* 端口

VNCSERVERARGS[1]="-geometry 1200x800"

# 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:
# http://kbase.redhat.com/faq/docs/DOC-7028

# 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="1:root"
VNCSERVERARGS[1]="-geometry 1200x800"
# VNCSERVERS="2:myusername"
# VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -localhost"

5).重启vncserver服务

#service vncserver restart

三、允许root访问图形界面和生成新的machine-id

#sed -i 's/.*!= root.*/#&/' /etc/pam.d/gdm 
#dbus-uuidgen >/var/lib/dbus/machine-id

四、关闭selinux和NetworkManager服务

1.检查selinux服务并关闭

#vi /etc/selinux/config

确认里面的SELINUX字段的值是disabled，如果不是则改为disabled。

[root@AY1404171530212980a0Z ~]# vi /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#       enforcing - SELinux security policy is enforced.
#       permissive - SELinux prints warnings instead of enforcing.
#       disabled - SELinux is fully disabled.
SELINUX=disabled
# SELINUXTYPE= type of policy in use. Possible values are:
#       targeted - Only targeted network daemons are protected.
#       strict - Full SELinux protection.
SELINUXTYPE=targeted
~

2.关闭NetworkManager服务

#chkconfig --del NetworkManager

五、测试登录：
