VMware安装CentOS 7-64（2）

一、yum安装软件

1.安装lrzsz、wget、vim

yum -y install lrzsz

yum -y install wget

查看vim：rpm -qa|grep vim

vim-enhanced-XXXXXXX

vim-minimal-XXXXXXXX

vim-common-XXXXXXXXX

缺少哪个就用命令安装：

例：yum -y install vim-enhanced

都没有，使用： yum -y install vim*

2.修改为国内yum源

切换目录：cd /etc/yum.repos.d/

备份：mv CentOS-Base.repo CentOS-Base.repo.backup

任意选择下面一种：

阿里：wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

网易：wget Centos7: http://mirrors.163.com/.help/CentOS7-Base-163.repo

中科大：wget Centos7: https://lug.ustc.edu.cn/wiki/_export/code/mirrors/help/centos?codeblock=3

搜狐：wget http://mirrors.sohu.com/help/CentOS-Base-sohu.repo

清理缓存：yum clean all

生成缓存：yum makecache

更新：yum -y update

3.添加nginx源

安装源：rpm -ivh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

查看可安装Nginx软件：yum info nginx

启动Nginx服务：service nginx start

4.epel源

安装源：rpm -ivh http://dl.fedoraproject.org/pub/epel/7/x86_64/Packages/e/epel-release-7-11.noarch.rpm
