一、CentOS 7下载

二、CentOS安装（VMware搭建）：最小安装

1、创建VM

网络模式：这里使用桥接模式

2、CentOS配置--安装配置

网路配置：这里网路配置为自动获取，需要打开网卡的自动获取开关

设置root密码

三、CentOS配置

1、修改网络为静态IP

修改/etc/sysconfig/network-scripts/ifcfg-ens32文件，输入

TYPE="Ethernet"PROXY_METHOD="none"BROWSER_ONLY="no"BOOTPROTO="static"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="35107365-f0d1-42b3-a042-582b55de1b8b"DEVICE="ens33"ONBOOT="yes"IPADDR=192.168.2.106NETMASK=255.255.255.0GATEWAY=192.168.2.1

重启网路

service network restart

2、配置国内yum源

系统默认的yum 源速度往往不尽人意，为了达到快速安装的目的，在这里修改yum源为国内源。

a. 修改/etc/yum.repos.d/CentOS-Base.repo为：

# CentOS-Base.repo## The mirror system uses the connecting IP address of the client and the# update status of each mirror to pick mirrors that are updated to and# geographically close to the client.  You should use this for CentOS updates# unless you are manually picking other mirrors.## If the mirrorlist= does not work for you, as a fall back you can try the# remarked out baseurl= line instead.##[base]name=CentOS-$releasever - Base#mirrorlist=http://mirrorlist.centos.org/?release=releasever&arch=basearch&repo=osbaseurl=http://ftp.sjtu.edu.cn/centos/releasever/os/basearch/gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7#released updates[updates]name=CentOS-$releasever - Updates#mirrorlist=http://mirrorlist.centos.org/?release=releasever&arch=basearch&repo=updatesbaseurl=http://ftp.sjtu.edu.cn/centos/releasever/updates/basearch/gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7#additional packages that may be useful[extras]name=CentOS-$releasever - Extras#mirrorlist=http://mirrorlist.centos.org/?release=releasever&arch=basearch&repo=extrasbaseurl=http://ftp.sjtu.edu.cn/centos/releasever/extras/basearch/gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7#additional packages that extend functionality of existing packages[centosplus]name=CentOS-$releasever - Plus#mirrorlist=http://mirrorlist.centos.org/?release=releasever&arch=basearch&repo=centosplusbaseurl=http://ftp.sjtu.edu.cn/centos/releasever/centosplus/basearch/gpgcheck=1enabled=0gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7#contrib - packages by Centos Users[contrib]name=CentOS-$releasever - Contrib#mirrorlist=http://mirrorlist.centos.org/?release=releasever&arch=basearch&repo=contribbaseurl=http://ftp.sjtu.edu.cn/centos/releasever/contrib/basearch/gpgcheck=1enabled=0gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
