Centos7最小化安装

1、先使用minimal安装系统

2、配置网络：dhcp或者静态ip，修改/etc/sysconfig/network-scripts/ifcfg-eth0文件；配置DNS,修改/etc/resolv.cf，增加nameserver

3、安装基本网络组件：

yum install net-tools
yum install wget

4、更改源，阿里源比较快：

mkdir /etc/yum.repos.d/backup
mv /etc/yum.repos.d/*.repo backup
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum clean all
yum makecache

3、安装组件：

yum install gcc
yum install selinux-policy-devel
yum install epel-release
yum install dkms
yum install nmap
yum install java
yum install yum-axelget
yum install gcc-c++
yum install make
yum install gdb
yum install cmake
yum install git
yum install unzip
yum install libtool
yum install libxml2
yum install libcurl
yum install openssl
yum install zlib
yum install python-pip

4、禁用组件：

systemctl stop firewalld       #停止防火墙
systemctl disable firewalld    #禁止防火墙自启动
