centos7新装系统基础配置

1、查版本号（CentOS是RedHat的社区发行版本）

[root@localhost /]# cat /etc/redhat-release

CentOS Linux release 7.1.1503 (Core)

[root@localhost /]# cat /etc/centos-release

CentOS Linux release 7.1.1503 (Core)

2、安装yum

[root@localhost /]# mkldir /mnt/aa /mnt/localyum

[root@localhost /]# mount /dev/cdrom/ /mnt/aa

[root@localhost /]# cp /mnt/aa/* /mnt/localyum -R

[root@localhost /]# umount /dec/cdrom

[root@localhost /]# rm -Rf /mnt/aa

[root@localhost /]# cat /etc/yum.repos.d/local.repo

[local]

name=local

baseurl=file:///mnt/localyum/

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

enabled=1

3、centos7查询ip的命令为ip addr，需要安装net-tools才能使用ifconfig

[root@localhost ~]# yum install net-tools

[root@localhost ~]# which ifconfig

/usr/sbin/ifconfig

4、安装虚拟机工具

[root@localhost ~]# mount /dec/cdrom /mnt/aa

[root@localhost ~]# cp /mnt/aa/* /mnt/vmtools

[root@localhost ~]# tar -zxvf  VMwareTools-9.9.3-2759765.tar.gz

[root@localhost ~]# cd /mnt/vmtools/vmware-tools-distrib

[root@localhost~]# ls /mnt/hgfs/linux_pac/

perl-5.22.0.tar.gz  gcc-4.6.1.tar.bz2
