lighttpd+PHP（php-fpm）基于docker-compose

Posted on Views:

搭建**lighttpd + PHP（php-fpm）基于 docker-compose 的最简生产环境：

  • lighttpd 配置
  • php-fpm 配置
  • docker-compose 编排

env

  • lighttpd
  • php-fpm
  • docker

1. 目录结构

project/
├── docker-compose.yml
├── lighttpd/
│   ├── Dockerfile
│   └── lighttpd.conf
└── php/
    ├── Dockerfile
    └── php.ini

1.1 docker-compose.yml

services:
  lighttpd:
    build: ./lighttpd
    container_name: lighttpd
    ports:
      - "8080:80"
    depends_on:
      - php
    volumes:
      - ./www:/var/www/html
    networks:
      - app-net

  php:
    build: ./php
    container_name: php-fpm
    expose:
      - "9000"
    volumes:
      - ./www:/var/www/html
    networks:
      - app-net

networks:
  app-net:
    driver: bridge

1.2 lighttpd Dockerfile

FROM alpine:3.19

RUN apk add --no-cache lighttpd lighttpd-mod_fastcgi php81

COPY lighttpd.conf /etc/lighttpd/lighttpd.conf

EXPOSE 80

CMD ["lighttpd", "-D", "-f", "/etc/lighttpd/lighttpd.conf"]

1.3 lighttpd.conf（FastCGI对接 PHP-FPM）

server.document-root = "/var/www/html"
server.port = 80

server.username = "lighttpd"
server.groupname = "lighttpd"

# 允许 index.php
index-file.names = ( "index.php", "index.html" )

server.modules += (
   "mod_access",
   "mod_accesslog",
   "mod_fastcgi",
   "mod_rewrite"
)

# FastCGI 连接 PHP-FPM
fastcgi.server = (
  ".php" => (
    "localhost" => (
      "host" => "php",
      "port" => 9000,
      "broken-scriptfilename" => "enable"
    )
  )
)

# 日志
accesslog.filename = "/var/log/lighttpd/access.log"

注意：host = "php" 对应 docker-compose 里的 service 名称。

2. PHP 容器

使用 php-fpm（推荐 Alpine 轻量版）

2.1 php/Dockerfile

FROM php:8.1-fpm-alpine

RUN docker-php-ext-install mysqli pdo pdo_mysql

COPY php.ini /usr/local/etc/php/

WORKDIR /var/www/html

2.2 php.ini

1

3
display_errors=On
upload_max_filesize=20M
post_max_size=20M

3. index.php

放到 ./www/index.php

1
2
<?php
phpinfo();

4. 启动服务

1
docker-compose up -d --build

访问：

http://localhost:8080

你将看到 phpinfo 页面，证明 lighttpd → FastCGI → php-fpm 工作正常。
