可以从http://mirrors.163.com/centos/7.3.1611/isos/x86_64/ 下载，有网络的话，用CentOS-7-x86_64-Minimal-1611.iso 就够了，没有就下载EveryThing版本吧
2、VmwareworkStation配置网络
vi /etc/sysconfig/network-scripts/ifcfg-ens33
IPV6INIT=no BOOTPROTO=static IPADDR=192.168.2.110 NETMASK=255.255.255.0 GATEWAY=192.168.2.1
vi /etc/NetworkManager/NetworkManager.conf 文件，在main部分添加 “dns=none” 选项：
[main] plugins=ifcfg-rh dns=none
NetworkManager重新装载上面修改的配置
# systemctl restart NetworkManager.service
手工修改 /etc/resolv.conf
nameserver 114.114.114.114 nameserver 233.5.5.5
重启后生效
service network restart
3、修改yum地址
参考http://mirrors.163.com/.help/centos.html设置
先备份repo，在新建一个centos.repo
[base] name=CentOS-$releasever - Base - 163.com #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os baseurl=http://mirrors.163.com/centos/$releasever/os/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7 #released updates [updates] name=CentOS-$releasever - Updates - 163.com #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates baseurl=http://mirrors.163.com/centos/$releasever/updates/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7 #additional packages that may be useful [extras] name=CentOS-$releasever - Extras - 163.com #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras baseurl=http://mirrors.163.com/centos/$releasever/extras/$basearch/ gpgcheck=1 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus - 163.com baseurl=http://mirrors.163.com/centos/$releasever/centosplus/$basearch/ gpgcheck=1 enabled=0 gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7
考虑到要安装docker等等，安装epel
yum -y install epel-release yum repolist
后面用yum install就可以安装了
先用
yum -y update
先更新到最新版本，再安装软件
