源码的好处是比较灵活，想放哪里定制路径就放哪里

前提准备：Centos7系统、下载httpd2.4源代码、安装编译前的软件环境；连接教室物理网络。

1、下载httpd2.4.25源码
[root@Magedu ~]# yum -y install lftp
[root@Magedu ~]# lftpget ftp://172.18.0.1/pub/Sources/sources/httpd/httpd-2.4.25.tar.bz2
将下载好的http2.4.25进行解压缩，
[root@centos7 data]# ll
total 6268
-rw------- 1 root root 1421 Jan 30 13:05 anaconda-ks.cfg
-rwxr-xr-x 1 root root 360 Jan 26 14:24 hallo.sh

95 directories, 2776 files
可以看到有非常多“ . c ”文件，
[root@centos7 httpd-2.4.25]# find -name "*.c" |wc -l
284 共284个
对于此类复杂脚本如何编译安装，我们接着看：

2、安装编译前的环境即安装Development tools包组及依赖
[root@Magedu ~]# yum -y groupinstall “Development Tools”
[root@centos7 httpd-2.4.25]# make
make: *** No targets specified and no makefile found. Stop.
[root@centos7 httpd-2.4.25]# which make
/usr/bin/make
[root@centos7 httpd-2.4.25]# rpm -qf /usr/bin/make
make-3.82-23.el7.x86_64
[root@centos7 httpd-2.4.25]# file /usr/bin/make
/usr/bin/make: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, BuildID[sha1]=77eee6e2b89ced609bef92cd9ef75bb7e056d83b, stripped
make本身是一个二进制文件，要借助于mskefile文本文件。
我们要在Makefile文件中放安装路径，那些文件启用哪些文件不启用。利用 make 项目管理器就能实现自动安装和编译安装。

3、预编译config配置
[root@centos7 httpd-2.4.25]# ./configure --prefix=/apps/httpd/ --sysconfdir=/etc/httpd/ --enable-ssl

此处报错提示“ checking for APR... no ”，我们要安装的是“ yum install apr-devel ”。

我们再次检查，报错提示：

我们按上面的思路安装即可。第一次安装无经验，下一次安装就知道缺什么，就可直接安装了。

4、编译：[root@Magedu httpd-2.4.25]# make -j 4
注意：使用-j 4表示编译时，使用4个cpu同时工作

5、安装：[root@Magedu httpd-2.4.25]# make install
6、添加全局环境变量即将执行命令和帮助文档的路径写入PATH
[root@Magedu httpd-2.4.25]# vim /etc/profile.d/env.sh
添加：
export PATH=/app/apache24/BIN:$PATH
使其立即生效：
[root@Magedu httpd-2.4.25]# source
/etc/profile.d/env.sh
配置帮助文档路径：
[root@Magedu httpd-2.4.25]# vim /etc/man_db.conf
添加：
MANDATORY_MANPATH
/app/apache24/man

7、关闭防火墙：
[root@Magedu ~]# apachectl start
[root@Magedu ~]# iptables -F
完成！
