How to Compile PHP 8.3 Locally and Deploy a ThinkPHP 8.0 Application

Overview

This tutorial explains how to build PHP 8.3 from source on a Linux system, set up PHP‑FPM as a systemd service, and then install the ThinkPHP 8.0 framework using Composer. It also covers Nginx configuration and basic verification of the deployment.

Install PHP 8.3

Download source

wget https://www.php.net/distributions/php-8.3.1.tar.gz
 tar -zxvf php-8.3.1.tar.gz

Install required packages

sudo apt-get install libfcgi-dev libfcgi0ldbl libjpeg-turbo8-dev \
 libmcrypt-dev libssl-dev libc-client2007e libc-client2007e-dev libxml2-dev \
 libbz2-dev libcurl4-openssl-dev libjpeg-dev libpng-dev libfreetype6-dev \
 libkrb5-dev libpq-dev libxslt1-dev libzip-dev libsqlite3-dev libonig-dev \
 pkg-config libkrb5-dev libssl-dev libbz2-dev libpng-dev libfreetype6-dev \
 libc-client2007e-dev libonig-dev libreadline-dev libxslt1-dev libzip-dev

If a package is missing, you can search for it with apt-cache search <name> and install the appropriate one.

Configure and compile

cd php-8.3.1

./configure \
  --prefix=/usr/local/php-8.3.1 \
  --with-config-file-path=/usr/local/php-8.3.1/etc \
  --with-zlib-dir \
  --with-freetype \
  --enable-mbstring \
  --enable-soap \
  --enable-calendar \
  --with-curl \
  --with-zlib \
  --enable-gd \
  --disable-rpath \
  --enable-inline-optimization \
  --with-bz2 \
  --enable-sockets \
  --enable-sysvsem \
  --enable-sysvshm \
  --enable-pcntl \
  --enable-mbregex \
  --enable-exif \
  --enable-bcmath \
  --with-mhash \
  --with-zip \
  --with-pdo-mysql \
  --with-mysqli \
  --with-mysql-sock=/var/run/mysqld/mysqld.sock \
  --with-jpeg \
  --with-openssl \
  --with-fpm-user=www \
  --with-fpm-group=www \
  --with-libdir=/lib/x86_64-linux-gnu \
  --enable-ftp \
  --with-kerberos \
  --with-gettext \
  --with-xmlrpc \
  --with-xsl \
  --enable-opcache \
  --enable-intl \
  --with-pear \
  --enable-fpm

Build and install

make
make install

The installation logs show binaries placed under /usr/local/php-8.3.1, including the CLI, FPM daemon, and related utilities.

Configure PHP

Verify version

/usr/local/php-8.3.1/bin/php -v

php.ini

sudo cp php.ini-production /usr/local/php-8.3.1/etc/php.ini

Set cgi.fix_pathinfo=0 to prevent Nginx from exposing scripts unintentionally.

PHP‑FPM configuration

sudo mv /usr/local/php-8.3.1/etc/php-fpm.conf.default \
     /usr/local/php-8.3.1/etc/php-fpm.conf
sudo mv /usr/local/php-8.3.1/etc/php-fpm.d/www.conf.default \
     /usr/local/php-8.3.1/etc/php-fpm.d/www.conf

User and group

user = www
group = www
listen.owner = www
listen.group = www
listen.mode = 0660

Optionally adjust ownership of the configuration file: chown www:www /opt/php-8.3.1/etc/php-fpm.d/www.conf.

Listen socket

#listen = 127.0.0.1:9000   ; comment out to disable TCP
listen = /var/run/php8.3.1-fpm.sock   ; use Unix socket

Create systemd service

[Unit]
Description=The PHP 8.3.1 FastCGI Process Manager
After=network.target

[Service]
Type=simple
PIDFile=/usr/local/php-8.3.1/var/run/php-fpm.pid
ExecStart=/usr/local/php-8.3.1/sbin/php-fpm --nodaemonize \
          --fpm-config /usr/local/php-8.3.1/etc/php-fpm.conf
ExecReload=/bin/kill -USR2 $MAINPID

[Install]
WantedBy=multi-user.target

sudo systemctl enable php-8.3.1-fpm.service
sudo systemctl daemon-reload
sudo systemctl start php-8.3.1-fpm.service
sudo systemctl status php-8.3.1-fpm.service

Install ThinkPHP 8.0

Install Composer

wget https://getcomposer.org/download/latest-stable/composer.phar
php composer.phar -v   # verify installation

Optionally configure the Alibaba Cloud mirror:

php composer.phar config -g repo.packagist composer https://mirrors.aliyun.com/composer/

Create ThinkPHP project

php composer.phar create-project topthink/think tp8.0
# output shows downloading and extracting the framework

Project structure includes app, public, config, vendor, etc.

Nginx configuration for ThinkPHP

server {
    listen 80;
    server_name 121.128.128.128;
    set $root_path /home/www/build/tp8.0/public;
    root $root_path;
    location / {
        if (!-e $request_filename) {
            rewrite ^(.*)$ /index.php?s=/$1 last;
            break;
        }
    }
    location ~ \.php$ {
        try_files $fastcgi_script_name =404;
        include fastcgi_params;
        fastcgi_pass unix:/var/run/php8.3.1-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_buffer_size 128k;
        fastcgi_buffers 4 256k;
        fastcgi_busy_buffers_size 256k;
        fastcgi_connect_timeout 10000;
        fastcgi_send_timeout 6000;
        fastcgi_read_timeout 6000;
    }
}

After reloading Nginx, visiting http://121.128.128.128 should display the ThinkPHP welcome page.

Verify PHP installation

vim public/tinywan.php
<?php
phpinfo();
?>

Access http://121.128.128.128/tinywan.php to see the PHP information page.
