第四周练习记录

第四周
1、自建yum仓库，分别为网络源和本地源

删掉原yum源

rm-rf  /etc/yum.repos.d/*

 

挂载光盘下的centos7安装包

mount /dev/sr0 /mnt/

 

创建yum源

vim  /etc/yum.repos.d/base.repo



[base]
name=base
baseurl=file:///mnt/
https://mirrors.aliyun.com/centos/$releasever/os/$basearch/
https://mirrors.cloud.tencent.com/centos/$releasever/os/$basearch/
https://repo.huaweicloud.com/centos/$releasever/os/$basearch/
https://mirrors.tuna.tsinghua.edu.cn/centos/$releasever/os/$basearch/

 

 

[epel]
name=epel
baseurl=https://mirrors.aliyun.com/epel/$releasever/x86_64/
https://mirrors.cloud.tencent.com/epel/$releasever/x86_64/
https://mirrors.huaweicloud.com/epel/$releasever/x86_64/
https://mirrors.tuna.tsinghua.edu.cn/epel/$releasever/x86_64/
gpgcheck=0
enabled=1

 


[extras]
name=extras
baseurl=https://mirrors.aliyun.com/centos/$releasever/extras/$basearch/
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。
最小化安装建议先安装相关包

yum install gcc make autoconf gcc-c++ glibc glibc-devel pcre pcre-devel openssl
openssl-devel systemd-devel zlib-devel vim lrzsz tree tmux lsof tcpdump wget
net-tools iotop bc bzip2 zip unzip nfs-utils man-pages

 

下载httpd-2.4.48.tar.bz2

tar -jxvf httpd-2.4.48.tar.bz2
cd httpd-2.4.48
./configure

 

报错显示：configure: error: APR not found. Please read the documentation

下载并编译安装apr

wget https://mirrors.tuna.tsinghua.edu.cn/apache//apr/apr-1.7.0.tar.bz2
cd apr-1.7.0 ; ./configure --prefix=/usr/local/apr
make ; make install

 

继续安装httpd

cd /date/httpd-2.4.48 ;./configure
#报错显示：configure: error: APR-util not found. Please read the documentation.

下载编译安装apr-util

wget https://mirrors.tuna.tsinghua.edu.cn/apache//apr/apr-util-1.6.1.tar.gz
#解压后进入执行
./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
#make时报错：
make[1]: *** [xml/apr_xml.lo] Error 1
make[1]: Leaving directory `/date/apr-util-1.6.1'
make: *** [all-recursive] Error 1
#网上搜索后显示缺少了一个xml解析器yum 安装一个 expat-devel 包即可
yum -y install expat-devel
#继续编译安装apr-util
make&&make install

 

成功后；切换到httpd继续编译安装httpd：

./configure --prefix=/usr/local/httpd --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util/
#需指明apr以及apr-util路径
#执行成功后
make && make install
#成功最后显示
Installing configuration files
mkdir /usr/local/httpd/conf
mkdir /usr/local/httpd/conf/extra
mkdir /usr/local/httpd/conf/original
mkdir /usr/local/httpd/conf/original/extra
Installing HTML documents
mkdir /usr/local/httpd/htdocs
Installing error documents
mkdir /usr/local/httpd/error
Installing icons
mkdir /usr/local/httpd/icons
mkdir /usr/local/httpd/logs
Installing CGIs
mkdir /usr/local/httpd/cgi-bin
Installing header files
mkdir /usr/local/httpd/include
Installing build system files
mkdir /usr/local/httpd/build
Installing man pages and online manual
mkdir /usr/local/httpd/man
mkdir /usr/local/httpd/man/man1
mkdir /usr/local/httpd/man/man8
mkdir /usr/local/httpd/manual
make[1]: Leaving directory `/date/httpd-2.4.48'

开启httpd

usr/local/httpd/bin/httpd -k start

浏览器输入本地ip地址后：

 

 

 编译安装apache2.4.48成功

 

3、利用sed 取出ifconfig命令中本机的IPv4地址

ifconfig eth0 | sed -n '/inet /s#\(.*inet \)\(.*\)\( n.*\)#\2#gp'

 

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 -ri.bak '/^#/s/^#//' /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 -rn 's#(.*)/([^/]+)/?#\2#p'  #取基名
echo /etc/fstab/ | sed -rn 's#(.*)/([^/]+)/?#\1#p' #取目录名

 

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 移除软件包以及卑职文件
apt update 刷新存储库索引
apt upgrade 升级所有可升级的软件包
apt autoremove 自动删除不需要的包
apt full-upgrade在升级软件包是自动处理依赖关系
apt search 搜索应用程序
apt show 显示安装细节
apt list 列出包含条件的包
apt edit-sources 编辑源列表
