02 Apache 的安装

软件下载

apr：https://mirrors.cnnic.cn/apache/apr/apr-1.6.5.tar.gz
apr-util： http://archive.apache.org/dist/apr/apr-util-1.5.2.tar.gz
httpd：https://mirrors.cnnic.cn/apache/httpd/httpd-2.4.52.tar.gz

备注：apr 和apr-util 是一个通用的函数库，可以让httpd不关心底层的操作系统，很方便的移植
（比如从Linux 到 windows）
Apache最新版本为：2.4.52 （项目中使用2.4.38）

解压安装

[root@localhost software]# tar zxvf apr-1.6.5.tar.gz
[root@localhost software]# tar zxvf apr-util-1.6.1.tar.gz
[root@localhost software]# tar zxvf httpd-2.4.52.tar.gz

1. 安装 apr

[root@localhost software]# cd apr-1.6.5
[root@localhost apr-1.6.5]# ./configure —prefix=/usr/local/apr
[root@localhost apr-1.6.5]# make && make install

1. 安装apr-util

[root@localhost apr-1.6.5]# cd /root/software/apr-util-1.6.1
[root@localhost apr-util-1.6.1]# ./configure —prefix=/usr/local/apr-util —with-apr=/usr/local/apr
[root@localhost apr-util-1.6.1]# make

报错处理：
[root@localhost apr-util-1.6.1]# yum install expat-devel -y
[root@localhost apr-util-1.6.1]# make clean
[root@localhost apr-util-1.6.1]# make && make install
c. 安装httpd
[root@localhost apr-util-1.6.1]# cd /root/software/httpd-2.4.52
[root@localhost httpd-2.4.52]# ./configure —prefix=/usr/local/apache —with-apr=/usr/local/apr —with-apr-util=/usr/local/apr-util —enable-rewrite —enable-so —enable-headers —enable-expires —with-mpm=worker —enable-modules=most —enable-deflate —enable-ssl

报错处理：编译安装prce
下载：https://sourceforge.net/projects/pcre/files/pcre/8.45/pcre-8.45.tar.bz2/download
[root@localhost software]# tar jxvf pcre-8.45.tar.bz2
[root@localhost software]# cd pcre-8.45
[root@localhost pcre-8.45]# yum -y install gcc-c++ zlib-devel openssl-devel
[root@localhost pcre2-10.37]# ./configure —prefix=/usr/local/pcre
[root@localhost pcre2-10.37]# make && make

[root@localhost pcre2-10.37]# cd /root/software/httpd-2.4.52
[root@localhost httpd-2.4.52]# ./configure —prefix=/usr/local/apache —with-apr=/usr/local/apr —with-apr-util=/usr/local/apr-util —with-pcre=/usr/local/pcre —enable-rewrite —enable-so —enable-headers —enable-expires —with-mpm=worker —enable-modules=most —enable-deflate —enable-ssl
[root@localhost httpd-2.4.52]# make

故障处理：是因为安装 apr-util-1.6.x.tar.gz 导致的，须降低为apr-util-1.5.x.tar.gz
[root@localhost httpd-2.4.52]# cd ../
[root@localhost software]# wget http://archive.apache.org/dist/apr/apr-util-1.5.2.tar.gz
[root@localhost software]# tar -zxvf apr-util-1.5.2.tar.gz
[root@localhost software]# cd apr-util-1.5.2
[root@localhost apr-util-1.5.2]# ./configure —prefix=/usr/local/apr-util —with-apr=/usr/local/apr
[root@localhost apr-util-1.5.2]# make && make install

[root@localhost apr-util-1.5.2]# cd ../httpd-2.4.52
[root@localhost httpd-2.4.52]# ./configure —prefix=/usr/local/apache —with-apr=/usr/local/apr —with-apr-util=/usr/local/apr-util —with-pcre=/usr/local/pcre —enable-rewrite —enable-so —enable-headers —enable-expires —with-mpm=worker —enable-modules=most —enable-deflate —enable-ssl
[root@localhost httpd-2.4.52]# make && make install

查看加载的模块

[root@localhost httpd-2.4.52]# /usr/local/apache/bin/apachectl -M

编写测试文件

[root@localhost httpd-2.4.52]# echo “aaa” >> /usr/local/apache/htdocs/index.html

启动Apache
