Docker 安装 PHP
PHP + Apache 镜像、PHP-FPM + Nginx 组合，以及扩展怎么装。
Key Points图省事用 php:8.3-apache；要性能就用 php:8.3-fpm 配 Nginx。扩展用 docker-php-ext-install 装。
最快跑起来
Bash
docker run -d --name php -p 8080:80 \
-v "$PWD:/var/www/html" \
php:8.3-apache装扩展
Dockerfile
FROM php:8.3-fpm
RUN apt-get update && apt-get install -y --no-install-recommends \
libpng-dev libzip-dev libonig-dev \
&& docker-php-ext-install -j$(nproc) pdo_mysql gd zip mbstring opcache \
&& pecl install redis && docker-php-ext-enable redis \
&& apt-get purge -y --auto-remove \
&& rm -rf /var/lib/apt/lists/*
WORKDIR /var/www/html| Command | Use |
|---|---|
docker-php-ext-install | Built-in extensions (pdo_mysql, gd…) |
pecl install + docker-php-ext-enable | PECL extensions (redis, xdebug) |
docker-php-ext-configure | Extra flags before install |
PHP-FPM + Nginx
YAML
services:
php:
build: .
volumes:
- ./src:/var/www/html
nginx:
image: nginx:1.27-alpine
ports:
- "8080:80"
volumes:
- ./src:/var/www/html:ro
- ./nginx.conf:/etc/nginx/conf.d/default.conf:ro
depends_on:
- phpNGINX
server {
listen 80;
root /var/www/html;
index index.php index.html;
location ~ \.php$ {
fastcgi_pass php:9000; # 服务名:9000
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}Point
fastcgi_pass at the service name (php:9000), not 127.0.0.1 — which requires both containers on the same user-defined network.最快跑起来
Bash
docker run -d --name php -p 8080:80 \
-v "$PWD:/var/www/html" \
php:8.3-apache装扩展
Dockerfile
FROM php:8.3-fpm
RUN apt-get update && apt-get install -y --no-install-recommends \
libpng-dev libzip-dev libonig-dev \
&& docker-php-ext-install -j$(nproc) pdo_mysql gd zip mbstring opcache \
&& pecl install redis && docker-php-ext-enable redis \
&& apt-get purge -y --auto-remove \
&& rm -rf /var/lib/apt/lists/*
WORKDIR /var/www/html| 命令 | 用途 |
|---|---|
docker-php-ext-install | 内置扩展 |
pecl install | PECL 扩展 |
docker-php-ext-configure | 安装前传编译参数 |
PHP-FPM + Nginx
YAML
services:
php:
build: .
volumes:
- ./src:/var/www/html
nginx:
image: nginx:1.27-alpine
ports:
- "8080:80"
volumes:
- ./src:/var/www/html:ro
- ./nginx.conf:/etc/nginx/conf.d/default.conf:ro
depends_on:
- phpNGINX
server {
listen 80;
root /var/www/html;
index index.php index.html;
location ~ \.php$ {
fastcgi_pass php:9000; # 服务名:9000
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}fastcgi_pass 写服务名（如 php:9000）而不是 127.0.0.1，前提是两个容器在同一自定义网络里。
