1、自建yum仓库，分别为网络源和本地源
操作步骤解释：
1、将现有的RPM 包，放到同一个目录下，使用“createrepo” 命令进行元数据创建repodata。
2、将光盘镜像，挂载到某一目录下，里面自带repodata。
3、使用http服务或者nfs，以及vsftp服务进行网络共享。
4、客户端配置：必须在/etc/yum.repos.d/ 目录下，创建以 repo结尾的文件。
[base]
name=base #仓库取名字
baseurl=file:///misc/cd #共享方式及路径，必须是有repodata所在的目录
enabled=1 #是否开启本yum源
gpgcheck=0 #密钥检查 公网的源 建议开启，确保安全1）、创建yum仓库，生成repodta目录
2）、本地yum源，以光盘为例
[13:44:07 root@centos7 yum.repos.d]#mount /dev/sr0 /mnt
mount: /dev/sr0 is write-protected, mounting read-only[13:44:31 root@centos7 yum.repos.d]#vim base.repo
[13:44:49 root@centos7 yum.repos.d]#cat base.repo #本地资源，光盘镜像共享
[base]
name=base
baseurl=file:///mnt
enabled=1
gpgcheck=0[13:44:54 root@centos7 yum.repos.d]#yum clean all
Loaded plugins: fastestmirror, langpacks

repo id repo name status
base base 4,021
repolist: 4,0213）、安装httpd 服务，用于网络共享资源 (一定要先用浏览器测试下，资源是否可用)
[13:51:53 root@centos7 dnf]#yum install httpd -y #安装http 服务
[13:52:38 root@centos7 dnf]#systemctl start httpd #开启http 服务
[13:57:09 root@centos7 yum.repos.d]#cat dnf.repo #dnf 网络源配置
[dnf]
name=dnf
baseurl=http://192.168.1.190/dnf/
enbaled=1
gpgcheck=02、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)、http2.4.6 安装包下载：http://httpd.apache.org/download.cgi 并上传至服务器
2)、编译环境安装
[14:14:46 root@centos7 ~]#yum install pcre-devel zlib-devel openssl openssl-devel gcc -y
3)、进到目录，开始编译安装
[14:20:17 root@centos7 ~]#cd httpd-2.4.46/
[14:20:19 root@centos7 httpd-2.4.46]#pwd/root/httpd-2.4.46
./configure
make
make install4)、默认编译路径及服务启动与访问验证
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
1）、查看磁盘，将sda 进行新创建分区作为本次测试。磁盘信息如下：
[14:51:36 root@centos7 ~]#fdisk /dev/sda
