1、自建yum仓库，分别为网络源和本地源
本地源
#已将repo移动到备份文件夹了，/etc/yum.repos.d/为空
[root@centos7 data]#ls backupRepo/
CentOS-base.repo CentOS-CR.repo CentOS-Debuginfo.repo CentOS-fasttrack.repo CentOS-Media.repo CentOS-Sources.repo CentOS-Vault.repo CentOS-x86_64-kernel.repo docker-ce.repo
[root@centos7 data]#ls /etc/yum.repos.d/
[root@centos7 data]#
#repolist查看为空
[root@centos7 data]#yum repolist all
已加载插件：fastestmirror
Loading mirror speeds from cached hostfile
repolist: 0
#挂在磁盘到/data/ mnt文件夹
[root@centos7 data]#mount /dev/cdrom /data/mnt
mount: /dev/sr0 写保护，将以只读方式挂载
[root@centos7 data]#ls mnt/
CentOS_BuildTag EFI EULA GPL images isolinux LiveOS Packages repodata RPM-GPG-KEY-CentOS-7 RPM-GPG-KEY-CentOS-Testing-7 TRANS.TBL
创建repo文件 指向本地源
[root@centos7 data]#cat >> base.repo < [base]
> name=CentOS
> baseurl=file:///data/mnt/
> enable=1
> gpgcheck=1
> gpgkey-file:///data/mnt/RPM-GPG-KEY-CentOS-
RPM-GPG-KEY-CentOS-7 RPM-GPG-KEY-CentOS-Testing-7
> gpgkey-file:///data/mnt/RPM-GPG-KEY-CentOS-7
> EOF
[root@centos7 data]#mv base.repo /etc/yum.repos.d/
[root@centos7 data]#yum repolist
已加载插件：fastestmirror

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。

[root@centos8sec httpd-2.4.51]#ifconfig ens33 |sed -nr "2s/[^0-9]+([0-9.]+).*/1/p"
192.168.1.71
4、删除/etc/fstab文件中所有以#开头，后面至少跟一个空白字符的行的行首的#和空白字符
5、处理/etc/fstab路径,使用sed命令取出其目录名和基名
[root@centos8sec httpd-2.4.51]#echo /etc/fstab | sed -nr 's#(.*)/.*$#1#p' /etc
[root@centos8sec httpd-2.4.51]#echo /etc/fstab | sed -nr 's#.*/([^/]+)/?$#1#p'
fstab
