centos 6.4 卡在了进度条界面

1.从新启动

     reboot

     在进度条界面时按住F5，可以看到启动过程，定位到starting certmonger卡住了。

    原因分析：X11图形化界面服务引起的，导致开机无法进入图形化界面。 

    用xshell，或者secureCRT连接虚拟机

修改配置文件/etc/X11/，如果xorg.conf 存在，修改名字

mv /etc/X11/xorg.conf /etc/X11/old_xorg.conf

如果xorg.conf不存在

修改启动级别

vi /etc/inittab

# Default runlevel. The runlevels used are:

#   0 - halt (Do NOT set initdefault to this)

#   1 - Single user mode

#   2 - Multiuser, without NFS (The same as 3, if you do not have networking)

#   3 - Full multiuser mode

#   4 - unused

#   5 - X11

#   6 - reboot (Do NOT set initdefault to this)

#

id:5:initdefault:#把最底行的5改为3，

启动startx命令 ，可以进入操作界面

上面是网上的教程，试了我的操作界面一闪而过，查看日志

vi /var/log/Xorg.0.log

安装以下组件
yum groupinstall -y "Desktop" "Desktop Platform" "Desktop Platform Development"　 "Fonts" 　"General Purpose Desktop"　 "Graphical Administration Tools"　 "Graphics Creation Tools" 　"Input Methods" 　"X Window System" 　"Chinese Support [zh]"　"Internet Browser"
安装xorg组件
yum install xorg-x11*

执行startx success出现界面了，退出startx 界面又没了

重启系统变成了命令行输入用户名密码，通过startx才能启动操作界面。而且terminal 右键不能显示，只能通过系统查找

貌似第一个问题是编辑vi /etc/inittab，把最后一行改成5，重启生效了。

第二个问题是centos6.2以上默认右键都没有terminal，现添加方法 如下

1》  yum -y install nautilus-open-terminal

2》 shutdown -r now

OK
