Centos 7最小化安装后配置

1. 关闭SELINUX

vi /etc/sysconfig/selinux
SELINUX=disabled

1. 配置网卡(最小化安装后ifconfig无法使用)，该配置的前提是采用 NAT模式

vi /etc/sysconfig/network-scripts/ifcfg-enp0s3
ONBOOT=yes
:wq
service network restart
# 检查网卡
ip addr 或者 ping -c2 www.baidu.com

1. 更新yum

yum -y update

1. 联网后安装ifconfig

yum -y install net-tools

1. 安装常用工具

yum -y install curl telnet vim wget lrzsz
//修改vim配置
vim ~/.vimrc
set encoding=utf- " 文件编码
set number " 显示行号
set tabstop= " tab宽度为4
set softtabstop= " 设置一次可以删除4个空格
set expandtab " tab转换为空格
