#下载源代码并解压缩:
分别执行以下三条命令:

[root@centos7 ~]#wget https://downloads.apache.org/apr/apr-1.7.0.tar.bz2
[root@centos7 ~]#wget https://downloads.apache.org//apr/apr-util-1.6.1.tar.bz2
[root@centos7 ~]#wget https://downloads.apache.org//httpd/httpd-2.4.46.tar.bz2

**编译安装httpd-2.4 **

1. 编译安装apr
(在编译安装之前,要先解压apr 执行命令,然后CD进入apr-1.7.0 再指定路径到/apps/apr 后安装,过程如下:

[root@centos7 ~]#tar xvf apr-1.7.0.tar.bz2
[root@centos7 ~]#cd apr-1.7.0
[root@centos7 apr-1.7.0]#./configure --prefix=/apps/apr
[root@centos7 apr-1.7.0]#make && make install

2. 编译安装apr-util

[root@centos7 ~]#tar xvf apr-util-1.6.1.tar.bz2 
[root@centos7 ~]#cd ./apr-util-1.6.1/
[root@centos7 apr-util-1.6.1]#./configure --prefix=/apps/apr-util --with-apr=/apps/apr/
[root@centos7 apr-util-1.6.1]#make -j 2 && make install

CentOS 7 编译安装 httpd 2.4
3. 编译安装 httpd-2.4

[root@centos7 ~]#tar xvf httpd-2.4.46.tar.bz2 
[root@centos7 ~]#cd ./httpd-2.4.46
[root@centos7 httpd-2.4.46]#./configure --prefix=/apps/httpd24 \    #这里后面跟换行符 表示后面还需要输入数据 输入后按回车
 --enable-so \
 --enable-ssl \
 --enable-cgi \
 --enable-rewrite \
 --with-zlib \
 --with-pcre \
 --with-apr=/apps/apr/ \
 --with-apr-util=/apps/apr-util/ \
 --enable-modules=most \
 --enable-mpms-shared=all \
 --with-mpm=prefork
 [root@centos7 httpd-2.4.46]#make -j 4 && make install

编译安装后配置
Httpd编译过程:/apps/httpd24/build/config.nice
自带的服务控制脚本:/apps/httpd24/bin/apachectl

1、创建专用用户

root@centos7 ~]#useradd -s /sbin/nologin -r apache

2、指定运行httpd的用户

[root@centos7 ~]#vim /apps/httpd24/conf/httpd
[root@centos7 ~]#cat /apps/httpd24/conf/httpd
user apache
group apache

3、配置环境变量

[root@centos7 ~]#echo 'PATH=/apps/httpd24/bin:$PATH' > /etc/profile.d/httpd.sh
. /etc/profile.d/httpd.sh

创建service unit文件(CentOS 7 以上版本)

[root@centos7 ~]#cat /usr/lib/systemd/system/httpd24.service
[Unit]
