Virtual box时间同步

当虚拟机安装好之后,如果有一段时间没有启动,当下一次启动时后系统时间会变得和主机环境不一致,我们需要安装一些软件来保证每次开机后会与主机时间同步。

首先装载CD,选择 Devices -> Insert Guset Additions CD image

# 升级kernel
yum update kernel*

# 装载CD
mount -t iso9660 /dev/cdrom /media

cp -r /media /tmp/

cd /tmp/media

yum update -y kernel*

yum install gcc kernel-devel kernel-headers dkms make bzip2 perl

# 可选
sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config

# 重启
reboot


/tmp/media/VBoxLinuxAdditions.run

[root@localhost media]# ./VBoxLinuxAdditions.run
Verifying archive integrity... All good.

Could not find the X.Org or XFree86 Window System, skipping.

# 重启
reboot
