从零开始Apache2配置php服务并支持网页访问

前言

最近打算再做一版服务器状态查看的dashboard，采用“子服务器主动向主服务器推送自己的状态”的方案。一种方案是用php写，Apache作为后台服务器。简单写一下构建过程。

TL;DR

github有个docker compose做的lamp全套环境，只需要git clone 和 docker compose up -d两个命令就能直接搭好linux端的apache+mysql+php环境。试了下确实直接能用，可以参考https://github.com/sprintcube/docker-compose-lamp。

准备Apache2环境

以下均为Ubuntu 22.04的wsl，以root运行。配置apache2需要apr、apr-util的runtime包，可以从https://apr.apache.org/download.cgi下载，以及正则、压缩传输、加密、xml的库。

wget https://dlcdn.apache.org/apr/apr-1.7.4.tar.gz wget https://dlcdn.apache.org/apr/apr-util-1.6.3.tar.gz wget https://dlcdn.apache.org/httpd/httpd-2.4.58.tar.gz tar xf httpd-2.4.58.tar.gz tar xf apr-util-1.6.3.tar.gz tar xf apr-1.7.4.tar.gz mv apr-util-1.6.3 httpd-2.4.58/srclib/apr-util mv apr-1.7.4 httpd-2.4.58/srclib/apr apt install libpcre3 libpcre3-dev zlib1g-dev openssl libssl-dev libexpat1 libexpat1-dev cd httpd-2.4.58 && ./configure --prefix=/usr/local/apache2 # 可以设置下path # 系统里已经有过别的apr版本，可能报错configure: error: Cannot use an external APR with the bundled APR-util。此时可以为configure添加一个--with-included-apr参数 make install

准备PHP环境

从https://www.php.net/downloads.php下载最新的php包，从https://pkgconfig.freedesktop.org/releases/下载最新的php-config包，比如

# 准备php所需要的一些环境 wget https://pkgconfig.freedesktop.org/releases/pkg-config-0.29.2.tar.gz tar xf pkg-config-0.29.2.tar.gz cd pkg-config-0.29.2 && ./configure --with-internal-glib make install # 非常重要 export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/lib/x86_64-linux-gnu/pkgconfig # 最简化安装，详细方式见下方 apt install libxml2 libxml2-dev sqlite3 libsqlite3-dev wget https://www.php.net/distributions/php-8.2.12.tar.gz tar xf php-8.2.12.tar.gz cd php-8.2.12 ./configure --prefix=/usr/local/src/php-8.2.12 --sysconfdir=/etc/php-8.2.12 --with-apxs2=/usr/local/src/apache2/bin/apxs

也可以参考这篇文章，配置更丰富的configure，以下的部分为参考该文章配置的，即

apt install build-essential autoconf automake libtool libsqlite3-dev pkg-config libjpeg-dev libpng-dev libxml2-dev libbz2-dev libcurl4-gnutls-dev libssl-dev libffi-dev libwebp-dev libonig-dev libzip-dev libjpeg-dev cd php-8.2.12 && ./configure --prefix=/usr/local/src/php-8.2.12 --sysconfdir=/etc/php-8.2.12 --with-openssl --with-zlib --with-bz2 --with-curl --enable-bcmath --enable-gd --with-webp --with-jpeg --with-mhash --enable-mbstring --with-imap-ssl --with-mysqli --enable-exif --with-ffi --with-zip --enable-sockets --with-pcre-jit --enable-fpm --with-pdo-mysql --enable-pcntl --with-apxs2=/usr/local/src/apache2/bin/apxs

配置服务器

如果按以上方式安装，则修改/usr/local/apache2/conf/httpd.conf文件的ServerName选项到实际ip和端口。比如ServerName 172.19.202.144:80。这里的ip可以运行ifconfig看一下。

为了使apache对php文件进行解释执行，在httpd.conf文件添加：

SetHandler application/x-httpd-php

设置文档目录，比如

# # DirectoryIndex: sets the file that Apache will serve if a directory # is requested. # DirectoryIndex index.php index.html # # DocumentRoot: The directory out of which you will serve your # documents. By default, all requests are taken from this directory, but # symbolic links and aliases may be used to point to other locations. # DocumentRoot "/var/www/html" # # Possible values for the Options directive are "None", "All", # or any combination of: # Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews # # Note that "MultiViews" must be named *explicitly* --- "Options All" # doesn't give it to you. # # The Options directive is both complicated and important. Please see # http://httpd.apache.org/docs/2.4/mod/core.html#options # for more information. # Options Indexes FollowSymLinks # # AllowOverride controls what directives may be placed in .htaccess files. # It can be "All", "None", or any combination of the keywords: # AllowOverride FileInfo AuthConfig Limit # AllowOverride None # # Controls who can get stuff from this server. # Require all granted

检查下php模块是不是打开了：

LoadModule php_module modules/libphp.so

启动服务器

apachestl start # 假设在准备环境阶段设置了path

随后本地浏览器直接访问localhost即可。
