httpd编译安装

Apache安装问题：configure: error: APR not found . Please read the documentation:

Linux上安装Apache时，编译出现错误： 

checking for APR... no
configure: error: APR not found .  Please read the documentation

安装APR，下载所需软件包，如果此时计算机可以上网，执行命令下载文件：

wget http://archive.apache.org/dist/apr/apr-1.4.5.tar.gz
wget http://archive.apache.org/dist/apr/apr-util-1.3.12.tar.gz
wget http://jaist.dl.sourceforge.net/project/pcre/pcre/8.10/pcre-8.10.zip

apr not found问题

tar -zxf apr-1.4.5.tar.gz
cd  apr-1.4.5
./configure --prefix=/usr/local/apr
make && make install

APR-util not found问题

tar -zxf apr-util-1.3.12.tar.gz
cd apr-util-1.3.12
./configure --prefix=/usr/local/apr-util -with-apr=/usr/local/apr/bin/apr-1-config
make && make install

pcre问题

unzip -o pcre-8.10.zip
cd pcre-8.10
./configure --prefix=/usr/local/pcre
make && make install

最后编译Apache时加上：

--with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util/ --with-pcre=/usr/local/pcre

 
例如：

./configure --prefix=/usr/local/apache2 --enable-so --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util/ --with-pcre=/usr/local/pcre

================

httpd编译安装
===========================================
官网：http://httpd.apache.org/
包：httpd-2.4.20.tar.bz2
注释：此处只考虑 2.4+ 的安装与配置，基于CentOS 6 和 CentOS 7。

（1）环境准备。
    ~]# yum -y install gcc gcc-c++ apr-devel apr-util-devel pcre pcre-devel openssl openssl-devel
    ~]# tar -axf httpd-2.4.20.tar.bz2
    ~]# cd httpd-2.4.20/

（2）注意事项。
    CentOS 6：注意事项
        apr 与 apr-util 官网下载地址：http://apr.apache.org/download.cgi
        版本要求：
            (1) apr             version >= 1.4+
                ~]# ./configure  --prefix=/usr/local/apr
                ~]# make && make install

            (2) apr-util        version >= 1.4+
                ~]# ./configure  --prefix=/usr/local/apr-util  --with-apr=/usr/local/apr
                ~]# make && make install

（3）编译安装。
    CentOS 6：
            ~]# ./configure --prefix=/usr/local/httpd --sysconfdir=/etc/httpd --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --enable-modules=all --enable-mpms-shared=all --with-pcre --with-libxml2 --enable-cgi  --with-mpm=prefork
    CentOS 7：
            ~]#   ./configure --prefix=/usr/local/httpd --sysconfdir=/etc/httpd --enable-modules=all --enable-mpms-shared=all --with-pcre --with-libxml2 --enable-cgi  --with-mpm=prefork

    ~]# make && make install

    注释：
        （1）--enable-mods-shared=all --enable-mods-static=all 只能选择一个，选择了 shared 之后还可以选择部分 static。（非必选）
        （2） --enable-load-all-modules 开启所有的选项，不要使用，开启了所有的会存在一些冲突，当需要的时候手动开启即可。
        （2）--enable-cgi 为模块。--with-pcre --with-libxml2 为扩展。（非必选）
        （3）--with-mpm=prefork 指定默认工作模型。（非必选）
        （4）--with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util  为 CentOS 6 系统的依赖。（CentOS 6 必选）

    查看编译了那些模块：
            ~]# ls /usr/local/httpd/modules

    查看加载了那些模块：
            ~]# /usr/local/httpd/bin/httpd -M
===============================================
常用选项解释：
Configuration:
    -h, --help             显示帮助文档并退出

Installation directories:
  --prefix=PREFIX         指定安装路径

Fine tuning of the installation directories:
    --sysconfdir=DIR        指定配置文件路径

Optional Features:
  --enable-load-all-modules     开启所有的加载模块
  --enable-modules=MODULE-LIST  开启模块 | "all" |"most" | "few" | "none" | "reallyall"
  --enable-mods-shared=MODULE-LIST    共享模块 |"all" | "most" | "few" | "reallyall"
  --enable-mods-static=MODULE-LIST   静态模块 |"all" | "most" | "few" | "reallyall"
  --enable-ssl            SSL/TLS ：构建 https
  --enable-mpms-shared=MPM-LIST    共享模块 | "all"
  --enable-rewrite        url 重写
  --enable-vhost-alias    虚拟主机
  --enable-proxy-fcgi     FastCGI 模块
  --enable-so            允许运行时加载DSO模块

Optional Packages:
    --with-apr=PATH         prefix for installed APR or the full path to apr-config
    --with-apr-util=PATH    prefix for installed APU or the full path to  apu-config
    --with-mpm=MPM        指定apache默认工作模式：MPM={event|worker|prefork|winnt}
    --with-pcre=PATH        perl语言兼容正则表达式)是一个用C语言编写的正则表达式函数库。
    --with-libxml2=PATH     Libxml2 是一个xml c语言版的解析器，还支持c++、PHP、Pascal、Ruby、Tcl等语言的绑定

========================================================
系统服务，启动，库，环境变量等设置。

（1）测试是否正常。
        自带启动脚本：
            /usr/local/httpd/bin/apachectl （start | stop | restart | graceful | graceful-stop）
        查看端口80是否被监听：
            ss -tnl

（2）加入环境变量
    临时生效：
        ~]# export PATH=/usr/local/httpd/bin:$PATH

    永久生效：
        ~]# vim /etc/profile.d/httpd.sh
           export PATH=/usr/local/httpd/bin:$PATH
        ~]# source /etc/profile.d/httpd.sh

    测试：（apachectl 现在是一个命令）
        ~]# apachectl （start | stop | restart | graceful | graceful-stop）

（3）导出库文件：
        ~]# ln -s /usr/local/httpd/include /usr/include/httpd

（4）导出man手册
    CentOS 6：
        ~]# vim /etc/man.config
    CentOS 7：
        ~]# vi /etc/man_db.conf

    写入：
        MANPATH /usr/local/httpd/man


（5）服务脚本文件
    CentOS 6：新加启动脚本。
