1. 编译源代码步骤
configure、Makefile.in一般是项目管理器自动生成的，这依赖于两个开发工具：
- autoconf：生成configure脚本文件；
- autoconf需要结合一个配置文件来和其它命令生成configure脚本；这个配置文件告诉autoconf当前代码有哪些特性、指定哪些安装路径等，而后才能生成configure脚本；
- automake：生成Makefile.in模板文件；
- automake也要结合一个文件，这个指明有多少程序文件、它们的依赖关系是什么、以及使用哪一种版本的编译器等，而后才能生成Makefile.in；
Note：在安装之前查看INSTALL和README文件查看安装方法，因为不同程序包安装步骤不一样，有的程序包不需要configure，直接make后执行make install；而有的程序包不需要执行make install，只有一个二进制文件直接复制即可完成；安装开发组件
想要进行编译，提前安装开发组件
CentOS 6：Development Tools、Server Platform Development
CentOS 7：Development Tools、Development and Creative Workstation(1) ./configure(也可能是config文件)
–help：获取支持使用的选项；
在执行make命令之前，用户指定程序包的编译参数、启用特性、安装路径等等；
configure脚本会收集当前系统上的开发环境中所依赖各组件的版本、特性等，并检查所依赖的环境是否能满足，如果检查到所依赖的程序包不存在立即报错，无法执行下一步。最后会根据用户指定信息和Makefile.in文件生成一个makefile文件；
##通用的几个选项
--prefix= ：指定安装的路径
--sysconfdir= ：指定配置文件目录
--enable-feature ：启用某个特性
--disable-fecture ：禁用特性
--with-function ：启用某功能
--without-function ：禁用某功能(2) make
每个源代码都有专用的makefile，在make时依据这个配置文件，调用指定的预处理器做处理、调用指定的编译器做处理、编译文件的顺序等操作等；(3) make install
其实是一些脚本，实现把构建出的应用程序，分别分配到用户指定的目录中；如创建出的二进制文件放到指定的二进制目录、库文件放到指定的库目录等等，使用install拷贝命令也能实现；2. 安装后的配置
(1) 将二进制程序目录添加至PATH文件变量中，否则只能使用绝对路径才能运行程序
编辑文件/etc/profile.d/NAME.sh
export PATH=/PATH/TO/BIN:$PATH(2) 导出库文件路径
编辑/etc/ld.so.conf.d/NAME.conf，添加新的库文件所在的目录至此文件中；
例如：/usr/local/apache2/lib
ldconfig -v：重新加载库文件路径，并查看；
ldconfig -p：查看已加载所有库文件路径；(3) 导出头文件
/usr/include/目录下，创建软链接；
ln -s target_dir soft_link ##可以导出一个目录为所有文件链接，也可以为每一个头文件导出一个链接，然后把创建的链接输出到/usr/include/目录下，或者直接复制头文件至/usr/include/目录；(4) 导出man手册
Centos7是在/etc/man_db.conf的40到50行之间，添加一个MANPATH参数(Centos6可能是/etc/man.config)；
MANPATH_MAP /usr/local/apache2/bin /usr/local/apache2/man 3. 编译安装实验
3.1. Centos7编译安装apache 2.2.27
系统版本与软件版本
[root@GNOME-C7 ~]# cat /etc/RedHat-release
CentOS Linux release 7.4.1708 (Core)
[root@GNOME-C7 ~]# uname -r
3.10.0-693.el7.x86_64
------------------------------------------------------------------
apr-1.6.3
apr-util-1.6.1
httpd-2.2.27提前安装开发环境[root@GNOME-C7 ~]# yum groupinstall -y "Development tools" "Development and Creative Workstation"
3.1.1. 安装apr-1.6.3
[root@GNOME-C7 ~]# cd apr-1.6.3/
root@GNOME-C7 apr-1.6.3]# ./configure -prefix=/usr/local/apr-1.6.3
[root@GNOME-C7 apr-1.6.3]# make
[root@GNOME-C7 apr-1.6.3]# make install3.1.2. 安装apr-util-1.6.1
[root@GNOME-C7 apr-1.6.3]# cd ../apr-util-1.6.1/
[root@GNOME-C7 apr-util-1.6.1]# ./configure -prefix=/usr/local/apr-unil-1.6.1 --with-apr=/usr/local/apr-1.6.3
[root@GNOME-C7 apr-util-1.6.1]# make
遇到报错：
xml/apr_xml.c:35:19: fatal error: expat.h: No such file or directory
#include <expat.h>
^
compilation terminated.
make[1]: *** [xml/apr_xml.lo] Error 1
make[1]: Leaving directory `/root/apr-util-1.6.1'
make: *** [all-recursive] Error 1
解决方法：yum install -y expat-devel
[root@GNOME-C7 apr-util-1.6.1]# make install3.1.3. 安装httpd-2.2.27
编译安装
[root@GNOME-C7 apr-util-1.6.1]# cd ../httpd-2.2.27/
[root@GNOME-C7 httpd-2.2.27]# ./configure --sysconfdir=/etc/httpd --prefix=/usr/local/apache2 --with-apr=/usr/local/apr-1.6.3 --with-apr-util=/usr/local/apr-unil-1.6.3 --with-mpm=prefork --with-included-apr --enable-mods-shared=most --enable-ssl --enable-suexec --enable-so
遇到报错：configure: error: ...No recognized SSL/TLS toolkit detected
解决方法：yum install -y openssl-devel
[root@GNOME-C7 httpd-2.2.27]# make
[root@GNOME-C7 httpd-2.2.27]# make install
编译第二次，从而得到httpd.worker ##这种方法不确定是否可以
[root@GNOME-C7 httpd-2.2.27]# cd ../
[root@GNOME-C7 ~]# rm -rf httpd-2.2.27/
[root@GNOME-C7 ~]# tar -xf httpd-2.2.27.tar.bz2
[root@GNOME-C7 ~]# cd ./httpd-2.2.27/
[root@GNOME-C7 httpd-2.2.27]# ./configure --sysconfdir=/etc/httpd --prefix=/usr/local/apache2 --with-apr=/usr/local/apr-1.6.3 --with-apr-util=/usr/local/apr-unil-1.6.3 --with-mpm=worker --with-included-apr --enable-mods-shared=most --enable-ssl --enable-suexec --enable-so
[root@GNOME-C7 httpd-2.2.27]# make ##不用执行make install否则就会覆盖当前apache的文件了
[root@GNOME-C7 httpd-2.2.27]# cp ./httpd /usr/local/apache2/bin/httpd.worker
本次使用的编译参数
--prefix=/PATH：指明安装路径；
--sysconfdir=/PATH：指明配置文件路径；不指明，默认在安装路径下；
--enable-so：表示启用DSO动态模块加载机制；
--enable-ssl：启用支持ssl功能；
--enable-mods-shared=most：表示动态的编译进来大多数的模块；如果使用--enable-mods-shared=all，则指动态的编译所有的模块。
--with-apr=/PATH：指明apr程序包的路径；不使用=指明路径会在默认路径查找；
--with-apr-util=/PATH：指明apr-util程序包的路径；
--with-mpm=prefork：指明默认使用的MPM模块；
说明：
静态编译：将module直接在安装的过程中放到apache中，当apache使用module的时候，就可以直接使用了。
动态编译：将module引入到apache之中，在使用的时候才会真正的去加载(通过LoadModule命令)
--with.....：表示依赖的包，不指明路径，编译安装时会到默认路径下找；
--without.....：不依赖的包；
--enable.....：启用特性；
--disable.....：禁用特性；
可能用到的其他参数
