最小化安装Linux系统后出现的问题

一、使用的系统是CentOS系统，刚搭建好的Cent 最小安装模式是没有ifconfig命令的。

[root@bogon ~]# ifconfig
-bash: ifconfig: 未找到命令

（1）修改网络配置文件

[root@bogon network-scripts]# cd /etc/sysconfig/network-scripts/
[root@bogon network-scripts]# ls
ifcfg-ens33
[root@bogon network-scripts]# vi ifcfg-ens33

TYPE="Ethernet"
PROXY_METHOD="none"
BROWSER_ONLY="no"
BOOTPROTO="dhcp"
DEFROUTE="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_FAILURE_FATAL="no"
IPV6_ADDR_GEN_MODE="stable-privacy"
NAME="ens33"
UUID="cfb1ad91-2690-47ed-9fcf-3ebefdd5bd1c"
DEVICE="ens33"
ONBOOT="yes"

（2）下载网络工具

[root@bogon network-scripts]# yum install net-tools

（3）使用ifconfig命令查看端口

[root@bogon network-scripts]# ipconfig
-bash: ipconfig: 未找到命令
[root@bogon network-scripts]# ifconfig
