Nginx+Apache环境
项目生产环境：操作系统：CentOS> 需要的软件：
httpd-2.4.23.tar.gz
apr-1.5.2.tar.gz
apr-util-1.5.4.tar.gz
项目任务：搭建Nginx+Apache环境
项目目的：Nginx处理静态请求，动态请求交给Apache和PHP进行处理。即Nginx作为前端Web服务器，而Apache在后端只处理动态请求，实现动静态分离。
实战技巧：如何解决80端口冲突的问题？
安装难点：apr、apr-util软件包的安装及Apache配置。

Apache的安装与使用：
# pwd
/tools
1.获取软件：
#
wget http://archive.apache.org/dist/httpd/httpd-2.4.23.tar.gz
#
Wget http://archive.apache.org/dist/apr/apr-1.5.2.tar.gz
#
Wget http://archive.apache.org/dist/apr/apr-util-1.5.4.tar.gz
#
Wget http://exim.mirror.fr/pcre/pcre-8.10.tar.gz
2.安装基础包：
# yum install gcc gcc-c++ zlib zlib-devel openssl openssl-devel libtool pcre-devel openssl-devel –y
3.安装配置环境
# tar -zxvf httpd-2.4.23.tar.gz
# tar -zxvfapr-1.5.2.tar.gz
# tar -zxvfapr-util-1.5.4.tar.gz
# mv apr-1.5.2 httpd-2.4.23/srclib/apr
# mv apr-util-1.5.4 httpd-2.4.23/srclib/apr-util
# ./configure --prefix=/usr/local/pcre && make && make install
#
./configure \
--prefix=/usr/local/apache2 \
--enable-mods-shared=all \
--enable-deflate \
--enable-speling \
--enable-cache \
--enable-file-cache\
--enable-disk-cache\
--enable-mem-cache\
--enable-ssl \
--with-ssl=/usr/local/openssl/\
--enable-rewrite \
--enable-so \
--with-apr=/usr/local/apr/\
--with-apr-util=/usr/local/apr-util/\
--with-pcre=/usr/local/pcre \
--with-included-apr
#make && make install
# pwd
/usr/local/apache2/bin
# ./apachectl #启动服务

后续配置（优化Apache）
# vi /etc/init.d/httpd
#!/bin/bash
#chkconfig:35 85 15
/usr/local/apache2/bin/apachectl $1
# chmod +x /etc/init.d/httpd
root@sky9890 /]# service httpd stop
httpd (no pid file) not running
# service httpd start
# service httpd restart

It works!
