如何解決centos虛擬機無法啟動

如何解決centos虛擬機無法啟動？

用VMware虛擬機創建的一個centos桌面版系統。系統啟動時出現問題，在啟動certmonger之后，界面卡住，無法進入圖形界面，如圖：

解決方法：

首先，Ctrl+Alt+F2進入命令行界面，用root用戶登錄，查看/etc/X11/xorg.conf文件是否存在，如果存在，則執行命令：

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

重啟系統，看是否正常。

然后Ctrl+Alt+F2進入命令行界面，用root用戶登錄，修改文件/etc/inittab

vim/etc/inittab

# inittab is only used by upstart for the default runlevel. # ADDING OTHER CONFIGURATION HERE WILL HAVE NO EFFECT ON YOUR SYSTEM. # System initialization is started by /etc/init/rcS.conf # Individual runlevels are started by /etc/init/rc.conf # Ctrl-Alt-Delete is handled by /etc/init/control-alt-delete.conf # Terminal gettys are handled by /etc/init/tty.conf and /etc/init/serial.conf, # with configuration in /etc/sysconfig/init. # For information on how to write upstart event handlers, or how # upstart works, see init(5), init(8), and initctl(8).      # 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:

將最后一行id:5:initdefault:修改為id:3:initdefault:則開機默認進入命令行界面。

重啟進入命令行之后，執行startx，則可進系統圖形界面了！
