访问网址 https://developer.aliyun.com/mirror/centos?spm=a2c6h.13651102.0.0.3e221b11p84Dq9 ,按照网站中说明运行:

​ 注:更改原说明中CentOS-Base.repo为CentOS-Base.aliyun.repo,以免文件覆盖

1.2 编译安装http2.4,实现可以正常访问

访问网站http://httpd.apache.org/ ,下载httpd-2.4.46.tar.bz2压缩文件,并上传服务器。按INSTLL文件中说明,在http://apr.apache.org/ 网站下载apr与apr-util

# mkdir -p  /usr/src/httpd
# mkdir -p /app/httpd244
# mv  apr-1.7.0/* /usr/src/httpd/httpd-2.4.46/srclib/apr
# mv apr-util-1.6.1/* /usr/src/httpd/httpd-2.4.46/srclib/apr-util/
# cd  /usr/src/httpd
# tar xvf httpd-2.4.46.tar.bz2
# cd /usr/src/httpd/httpd-2.4.46

安装编译时使用到的软件

# yum -y install gcc make pcre-devel openssl-devel expat-devel

编译并安装

# cd /usr/src/httpd/httpd-2.4.46
# ./configure
# make && make install

后续设置

# setenforce 0
# vim /etc/sysconfig/selinux
SELINUX=disabled    #关闭Selinux

# systemctl stop firewalld.service   #关闭iptables

# vim  /etc/profile.d/httpd.sh  # 设置apachectl路径及自动启动httpd
PATH=$PATH:/app/httpd244/bin
export PATH
/app/httpd244/bin/apachectl restart

# vim /etc/man_db.conf  #设置man帮助路径
MANDATORY_MANPATH           /app/httpd244/man

# vim /app/httpd244/conf/httpd.conf  #更改httpd启动用户、用户组
User apache
Group apache

二、sed工具应用举例

2.1 利用sed 取出ifconfig命令中本机的IPv4地址

# ifconfig|sed -n '2p'|sed -r 's/(^[^0-9]+)([0-9.]+)(.*)/\2/'

2.2 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:]]+//' fstab

2.3 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/'  #取出目录名
# echo /etc/fstab | sed -r 's/(^\/.*\/)(.*)/\2/'  #取出基名
