1、自建yum仓库，分别为网络源和本地源
备份原有repo文件
[root@centos7 ~]# cd /etc/yum.repos.d/
[root@centos7 yum.repos.d]# mkdir repobak
[root@centos7 yum.repos.d]# mv *.repo repobak/
创建新的repo文件
vim test.repo
[base]
name=base
baseurl=file:///mnt/cdrom
gpgcheck=0
[epel]
name=epel
baseurl=https://mirrors.aliyun.com/epel/7/x86_64/
gpgcheck=1
gpgkey=https://mirrors.aliyun.com/epel/RPM-GPG-KEY-EPEL-7
验证yum源
[root@centos7 yum.repos.d]# yum repolist
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
repo id repo name status
!base base 10,097
!epel epel 13,195
repolist: 23,292
2.安装http2.4，实现可以正常访问，并将编译步骤和结果提交。
创建安装位置（文件夹）
mkdir /data/http24
安装编译工具
yum groups install "Development Tools"
yum install apr-util-devel apr-devel pcre-devel -y
下载源码包
http://mirror.bit.edu.cn/apache//httpd/httpd-2.4.41.tar.gz
解压缩源码包
tar xvf httpd-2.4.41
编译前可以查看一个README、INSTALL文档
less README
less INSTALL
编译安装http2.4
./configure --prefix=/data/http24
make
make install
启动服务
[root@centos7 /]# /data/http24/bin/apachectl -k start //启动服务
[root@centos7 /]# ss -tnl

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
建立需要的硬盘分区
[root@centos7 ~]# fdisk /dev/sdb
Welcome to fdisk (util-linux 2.23.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
Command (m for help): n
Partition type:
p primary (1 primary, 0 extended, 3 free)
e extended
Select (default p): p
Partition number (2-4, default 2):
First sector (20973568-104857599, default 20973568):
Using default value 20973568
Last sector, +sectors or +size{K,M,G} (20973568-104857599, default 104857599): +2G
Partition 2 of type Linux and of size 2 GiB is set
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.

格式化分区
