本文适用：rhel8系列，或同类系统(CentOS8,AlmaLinux8,RockyLinux8等)
文档形成时期：2023年
因系统版本不同，构建部署应略有差异，但本文未做细分，对稍有经验者应不存在明显障碍。
因软件世界之复杂和个人能力之限，难免疏漏和错误，欢迎指正。

背景

不同时期因各种原因经常产生部署LNMP环境的需求，某些场景下需要自定义软件，比如参数、模块、安装路径，或多个版本共存，不能采用Docker等容器环境，采用自主构建RPM包便成了比较快捷的方式之一。

环境准备

yum install rpmdevtools
#创建目录
rpmdev-setuptree
#或手动创建目录：

mkdir rpmbuild-php-8.1.20; cd rpmbuild-php-8.1.20
mkdir -p ./{BUILD,RPMS,SOURCES,SPECS,SRPMS}

依赖包和必要文件准备

#安装扩展源并启用PowerTools
dnf install epel-release
dnf config-manager --set-enabled PowerTools # 在CentOS8上，oniguruma-devel,aspell-devel位于PowerTools，
dnf config-manager --set-enabled powertools # 在Almalinux8上，oniguruma-devel,aspell-devel位于powertools，和CentOS8不同的是小写的。
#如果不启用，会提示：No match for argument: oniguruma-devel，No match for argument: aspell-devel

#通过dnf安装依赖
dnf -y install wget libxml2 libxml2-devel sqlite-devel bzip2-devel libcurl-devel libffi-devel libpng-devel libwebp-devel libjpeg-devel freetype-devel oniguruma oniguruma-devel libzip libzip-devel unixODBC unixODBC-devel freetds freetds-devel libtool-ltdl libtool-ltdl-devel gmp-devel libicu-devel openldap openldap-devel libpq libpq-devel aspell aspell-devel libtidy libtidy-devel libxslt libxslt-devel readline readline-devel libsodium libsodium-devel libjpeg-turbo-utils libXpm-devel systemd-devel openssl openssl-devel

cp -frp /usr/lib64/libldap* /usr/lib/

目录rpmbuild/SOURCES/下面的文件：
opcache.so php-8.1.20.tar.gz php-command.ini php-fpm.conf php.ini redis.so www.conf

说明：

• PHP配置建议参考生产环境的常用配置，准备一个比较通用的；
• opcache.so和redis.so是同环境下编译好的模块文件，这样可省略在RPM包构建过程中执行编译；

PHP is an HTML-embedded scripting language. Much of its syntax is
borrowed from C, Java and Perl with a couple of unique PHP-specific
features thrown in. The goal of the language is to allow web
developers to write dynamically generated pages quickly.%prep%setup -q%build

- For the first time, Custom made PHP8.1.20 in AlmaLinux8.8.

查看make参数：
rpm --eval %{?_smp_mflags}
可以看到是根据核线程数量来编译的。
