CentOS网络运维错误

自己所运用的是CentOS虚构机,在老大境况下有dhcp服务,本来用的喜爱得舍不得放手的,然而忽地冒出了如下错误:

错误:determining IP information for eth0 ... failed; no link present . Check cable?

Getting a DHCP Address in a Red Hat Linux 9.0 Virtual Machine
When a Red Hat Linux 9.0 guest operating system tries to get a DHCP address, the attempt may fail with an error message that states the link is down. On ESX Server, this happens only if you are using the vlance driver for your network connection.
To work around this problem, become root (su -) and use a text editor to edit the following files in the guest operating system. If only one of these files exist, make the change for that file only.
/etc/sysconfig/network-scripts/ifcfg-eth[n]
/etc/sysconfig/networking/devices/ifcfg-eth[n]
In both cases, [n] is the number of the Ethernet adapter — for example, eth0.
Add the following section to each of these two files:
check_link_down () {
return 1;
}

Then run the command ifup eth[n] (where [n] is the number of the Ethernet adapter) or restart the guest operating system.

结果自身试了一下依旧拾叁分,正是失误改造了成为了之类错误

determining IP information for eth0 ... failed;

新生想了一晃修改ifcfg-eth0,把原来的dhcp改为static,整个配置改成静态的,然后再重启互联网,就发掘可以了。
