ifconfig为什么没有显示对应IP信息_好文资源

这篇文章将为大家详开发云主机域名细讲解有关ifconfig为什么没有显示对应IP信息，文章内容质量较高，因此小编分享给大家做个参考，希望大家阅读完这篇文章后对相关知识有一定的了解。服务器之前可以连通192.167.10.11的，现在突然ping不同了。

1、ifconfig和ip addr都看不到本机192.168.10网段的IP

2、cat /etc/sysconfig/network-scripts/ifcfg-em2发现有192.168.10网段的IP，以为网线被拔掉了，后来到机房看网线是插好的

3、继续查询才发现192.168.10网段的IP对应的ONBOOT=no，重新ifconfig em2 up后解决

[root@ebsdev ~]# history |grep mount

704 mount 192.167.10.11:/volume1/dbsbak /dbsbak

742 umount /dbsbak

–ifconfig没有显示192.168.10网段的IP
