马哥教育N63013第四周作业

1、自建yum仓库，分别为网络源和本地源
配置本地源（centos7光驱源）：
1.挂载光驱至/mnt/cdrom

mount /dev/cdrom /mnt/cdrom

2.修改镜像源配置文件

vim /etc/yum.repos.d/centos7.repo
[CentOS7]
name=CentOS 7
baseurl=file:///mnt/cdrom
gpgcheck=0
enabled=1

3.清理yum缓存

yum clean all
yum makecache

配置网络源（centos7阿里云）：

1.备份yum源镜像文件

mv CentOS-Base.repo CentOS-Base.repo.bak

2.下载阿里云yum源镜像配置文件

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

3.清理yum缓存

yum clean all
yum makecache

配置网络源和本地源（Centos8）

vim /etc/yum.repos.d/base.repo
[BaseOS]
name=BaseOS
baseurl=file:///misc/cd/BaseOS
baseurl=https://repo.huaweicloud.com/centos/$releasever/
gpgcheck=1
gpgkey=/etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial                                                          
[AppStream]
name=AppStream
baseurl=file:///misc/cd/AppStream
baseurl=https://mirrors.huaweicloud.com/epel/$releasever/x86_64
gpgcheck=0
[epel]
name=EPEL
baseurl=http://mirrors.aliyun.com/epel/$releasever/Everything/$basearch
gpgcheck=0
enabled=1
[extras]
name=extras
baseurl=https://mirrors.aliyun.com/centos/$releasever/extras/$basearch/os
gpgcheck=0

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.安装相关包

yum install gcc make autoconf apr-devel apr-util-devel pcrdevel openssl-devel redhat-rpm-confige

2.下载httpd安装包并解压缩

wget https://dlcdn.apache.org//httpd/httpd-2.4.52.tar.bz2 --no-check-certificate
tar xvf httpd-2.4.52.tar.bz2 -C /usr/local/src/

3.配置

cd /usr/local/src/httpd-2.4.52/
./configure --prefix=/apps/httpd --sysconfdir=/etc/httpd --enable-ssl

4.编译并安装

make && make install

5.配置环境

echo 'PATH=/apps/httpd/bin:$PATH' > /etc/profile.d/httpd.sh
. /etc/profile.d/httpd.sh

6.运行apache

apachectl start

7.查看进程

ps aux|grep httpd

3、利用sed 取出ifconfig命令中本机的IPv4地址

ifconfig eth0|sed -n '2p'|sed -nr 's#(.*inet)(.*)(.*netmask.*)#\2#p'
10.0.0.150

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

sed -r 's/^#[[:space:]]*//' /etc/fstab


/etc/fstab

5、处理/etc/fstab路径,使用sed命令取出其目录名和基名

echo "/etc/fstab"| sed -r 's#^/(.*)/(.*)#\1#'
etc
echo "/etc/fstab"| sed -r 's#^/(.*)/(.*)#\2#'
fstab

6、列出ubuntu软件管理工具apt的一些用法(自由总结)

apt install 安装软件包
apt remove 移除软件包
apt purge 移除软件包以及配置文件
apt list 列出包含条件的包
apt search 搜索应用程序
apt show 显示安装细节
apt upgrade 升级所有可升级的包
apt update 刷新存储库索引
