1、自建yum仓库，分别为网络源和本地源
网络源
## 阿里云镜像地址为例
vi /etc/yum.repos.d/CentOS-Base.repo
[local]
name=CentOS-$releasever - Base - mirrors.aliyun.com
failovermethod=priority
baseurl=http://mirrors.aliyun.com/centos/$releasever/os/$basearch/
http://mirrors.aliyuncs.com/centos/$releasever/os/$basearch/
http://mirrors.cloud.aliyuncs.com/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7
或者
##下载rpm文件
wget http://mirrors.aliyun.com/repo/Centos-7.repo
##安装rpm即可直接生成repo文件
rpm -ivh https://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm
本地源
### 挂载光盘
mount /dev/sr0 /mnt/cdrom
### 编辑repo文件：
vi /etc/yum.repos.d/CentOS-Base.repo
[local]
name=localyum
baseurl=file:///mnt/cdrom/
gpgcheck=0
enabled=1
2、编译安装http2.4，实现可以正常访问，并将编译步骤和结果提交
（1）安装依赖包
yum -y install wget pcre-devel gcc gcc-c++ openssl-devel apr apr-util-devel
（2）下载源码包
wget http://mirrors.tuna.tsinghua.edu.cn/apache//httpd/httpd-2.4.41.tar.gz
（3）解压文件，编译
tar zxvf httpd-2.4.41.tar.gz
./configure --prefix=/soft/http --enable-http --enable-proxy --enable-ssl
make
make install
（4）启动
/soft/http/bin/apachectl start
3、创建一个2G的文件系统，块大小为2048byte，预留1%可用空间,文件系统 ext4，卷标为TEST，要求此分区开机后自动挂载至/test目录，且默认有acl挂载选项
##命令
### 划分磁盘
fdisk /dev/sdb
(n-->p-->+1932M-->w)
### 格式化ext4文件格式
mkfs.ext4 /dev/sdb1
### 打卷标
e2label /dev/sdb1 TEST
### 查看卷标
blkid
###创建挂载点目录
mkdir /test
### 编辑配置开机自动挂载
vi /etc/fstab
### 挂载
mount -a
