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 drwxr-xr-x 11 501 games 4096 Dec 17 2016 httpd-2.4.25 -rw-r--r-- 1 root root 6398218 Oct 15 08:31 httpd-2.4.25.tar.bz2 -rw-r--r-- 1 root root 984 Jan 24 20:34 magedu.pubkey [root@centos7 data]# du -sh httpd-2.4.25 43M httpd-2.4.25 [root@centos7 data]# cd httpd-2.4.25/ [root@centos7 httpd-2.4.25]# ls ABOUT_APACHE CMakeLists.txt INSTALL NWGNUmakefile acinclude.m4 config.layout InstallBin.dsp os Apache-apr2.dsw configure LAYOUT README Apache.dsw configure.in libhttpd.dep README.cmake apache_probes.d docs libhttpd.dsp README.platforms ap.d emacs-style libhttpd.mak ROADMAP build httpd.dep LICENSE server BuildAll.dsp httpd.dsp Makefile.in srclib BuildBin.dsp httpd.mak Makefile.win support buildconf httpd.spec modules test CHANGES include NOTICE VERSIONING [root@centos7 httpd-2.4.25]# tree │ └── wintty.mak ├── test │ ├── check_chunked │ ├── cls.c │ ├── Makefile.in │ ├── make_sni.sh │ ├── README │ ├── tcpdumpscii.txt │ ├── test_find.c │ ├── test_limits.c │ ├── test_parser.c │ ├── test_select.c │ ├── test-writev.c │ └── time-sem.c └── VERSIONING
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 checking for chosen layout... Apache checking for working mkdir -p... yes checking for grep that handles long lines and -e... /usr/bin/grep checking for egrep... /usr/bin/grep -E checking build system type... x86_64-unknown-linux-gnu checking host system type... x86_64-unknown-linux-gnu checking target system type... x86_64-unknown-linux-gnu configure: configure: Configuring Apache Portable Runtime library... configure: checking for APR... no configure: error: APR not found.

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： [root@centos7 httpd-2.4.25]# ./configure --prefix=/apps/httpd/ --sysconfdir=/etc/httpd/ --enable-ssl checking for chosen layout...

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！
