第六周作业

1、自建yum仓库，分别为网络源和本地源

cat >> /etc/yum.repo.d/ali.repo <<-EOF
#net阿里源
[base]
name=CentOS-$releasever - Base - mirrors.aliyun.com
baseurl=http://mirrors.aliyun.com/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-8
EOF

cat >> /etc/yum.repo.d/local.repo <<-EOF
#cenos8local源
[BaseOS]
name=BaseOS
baseurl=file:///media/centos/img/BaseOS/
gpgcheck=0                         
                             
[AppStream]
name=AppStream
baseurl=file:///media/centos/img/AppStream/
gpgcheck=0
EOF

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。

2.1，前往官网http://httpd.apache.org/download.cgi#apache24下载源码包

[root@explore ~]# wget https://mirrors.bfsu.edu.cn/apache//httpd/httpd-2.4.46.tar.bz2

2.2，配置yum源后安装编译工具及常用工具包

[root@explore ~]# yum install -y  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

2.3，解压源码包

[root@explore ~]# tar xf httpd-2.4.46.tar.bz2

2.4，进入该目录,进行编译

[root@explore httpd-2.4.46]# ./configure --sysconfdir=/etc/httpd/ --prefix=/data/httpd/ --enable-ssl 

checking for APR... no
configure: error: APR not found.  Please read the documentation.
[root@explore httpd-2.4.46]# 
#报错安装对应依赖包
[root@explore ~]#  yum install apr apr-util apr-devel -y
#报错
checking for APR-util... no
configure: error: APR-util not found.  Please read the documentation.
#解决
yum install -y apr-util-devel.x86_64
#再次执行
[root@explore httpd-2.4.46]# ./configure --sysconfdir=/etc/httpd/ --prefix=/data/httpd/ --enable-ssl 
#完成
config.status: executing default commands
configure: summary of build options:

    Server Version: 2.4.46
    Install prefix: /data/httpd/
    C compiler:     gcc -std=gnu99
    CFLAGS:           -pthread  
    CPPFLAGS:        -DLINUX -D_REENTRANT -D_GNU_SOURCE  
    LDFLAGS:           
    LIBS:             
    C preprocessor: gcc -E

2.5，编译

[root@explore httpd-2.4.46]# make && make install
Installing configuration files
mkdir /etc/httpd
mkdir /etc/httpd/extra
mkdir /etc/httpd/original
mkdir /etc/httpd/original/extra
Installing HTML documents
mkdir /data/httpd/htdocs
Installing error documents
mkdir /data/httpd/error
Installing icons
mkdir /data/httpd/icons
mkdir /data/httpd/logs
Installing CGIs
mkdir /data/httpd/cgi-bin
Installing header files
mkdir /data/httpd/include
Installing build system files
mkdir /data/httpd/build
Installing man pages and online manual
mkdir /data/httpd/man
mkdir /data/httpd/man/man1
mkdir /data/httpd/man/man8
mkdir /data/httpd/manual
make[1]: Leaving directory `/root/httpd-2.4.46'

2.6，配置环境变量

[root@explore httpd-2.4.46]# echo  "PATH=/data/httpd/bin/:$PATH" >> /etc/profile.d/httpd.sh

2.7，配置man帮助手册

vim /etc/man_db.conf
ANDATORY_MANPATH           /data/httpd/man

2.8，运行

[root@explore httpd-2.4.46]# . /etc/profile.d/httpd.sh 
[root@explore httpd-2.4.46]# apachectl 
#报错httpd: Could not reliably determine the server's fully qualified domain name, 
#讲httpd.com中的此行注释ServerAdmin you@example.com

2.9，访问

3、利用sed 取出ifconfig命令中本机的IPv4地址

[root@explore httpd-2.4.46]# ifconfig | sed -nE 's@inet (([[:digit:]]|\.)*).*@\1@p'

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

[root@explore httpd-2.4.46]#  sed -Ei.ba 's@(^#[[:space:]])(.*)+@\2@'  /etc/fstab
[root@explore httpd-2.4.46]# cat /etc/fstab

/dev/cdrom  /mnt/   iso9660 defaults    0  0

5、处理/etc/fstab路径,使用sed命令取出其目录名和基名

#目录名
[root@exploere2 ~]# echo /etc/fstab | sed -nE "s@(/.*/+)(.*)@\1@p"

#基名
[root@exploere2 ~]# echo /etc/fstab | sed -nE "s@(/.*/+)(.*)@\2@p"
