这个问题在刚学Linux遇到的,centOS7的网卡启动不起来,导致建不了集群。如下图没有ifconf-env33网卡的IP

-o  输出精确匹配的字符而不是默认的整行。

如果你遇到了,呵呵呵,迷之微笑。

 –color=auto  给匹配到的字符串加颜色(不是整行)  -n打印行号    

 

如果systemctl restart network.service 命令(重启网卡)依然不好使

 

再启动 ip link set  env3(网卡名) up还不好使

虚拟机网卡没起来,这个问题比较尴尬,我只能告诉你解决方法。。

 

一、关闭计算机。真的,小编调了一天错,在网上各种找解决办法。没曾想第二天自己好了。真是伤不起。虚拟机虽然好了。但预防第二次出现毛病,所以在网卡启动正常的时候启动了虚拟机快照功能,当你的环境有一点改变时你就可以保存快照,当网卡,或者虚拟机出各种毛病时就恢复快照。所以这个网卡没启动起来的虚拟机先放着它,注意不要关机,一直给它处于挂起状态。莫慌,电脑重新开机两次后还不好就不用管,等你第二天上线就会自然好。这个bug应该是虚拟机或者你的windows系统不稳定造成的。

二、启动起来之后一定要建立快照,快照,快照(重要事情!!)
