nginx容器与php-fpm容器连接方式

文档说明：只记录关键地方;

获得nginx和php基础镜像的内默认配置文件

从容器镜像中拷贝文件到容器外

#!/bin/bash

set -eux
__DIR__=$(
  cd "$(dirname "$0")"
  pwd
)
cd ${__DIR__}



mkdir -p conf

image=nginx:alpine
container_id=$(docker create $image) # returns container ID
docker cp $container_id:/etc/nginx/nginx.conf conf/nginx-default.conf
docker cp $container_id:/etc/nginx/conf.d/default.conf conf/nginx-default-domain.conf
docker rm $container_id

image=wenba100xie/php:7.1-fpm-alpine-202008121444
container_id=$(docker create $image) # returns container ID
docker cp $container_id:/usr/local/etc/php-fpm.conf conf/7.1-fpm-alpine-php-fpm.conf
docker cp $container_id:/usr/local/etc/php/php.ini  conf/7.1-fpm-alpine-php.ini
lsdocker cp $container_id:/usr/local/etc/php-fpm.d/www.conf conf/7.1-fpm-alpine-www.conf
docker rm $container_id


cp conf/7.1-fpm-alpine-www.conf default.conf
cp conf/7.1-fpm-alpine-www.conf www.conf

修改配置： nginx 配置 关键点

/etc/nginx/conf.d/default.conf

    root   /usr/share/nginx/html;
    location / 
        index  index.html index.htm index.php;
    }

    location ~* \.php$ {
        fastcgi_index   index.php;
        # fastcgi_pass    127.0.0.1:9000;
        fastcgi_pass    php-fpm:9000;  # 关键点：使用服务名称连接，而不是IP
        include         fastcgi_params;
        fastcgi_param   SCRIPT_FILENAME    $document_root$fastcgi_script_name;
        fastcgi_param   SCRIPT_NAME        $fastcgi_script_name;
    }

修改配置： php-fpm配置 关键点

/usr/local/etc/php-fpm.d/www.conf

; listen = 127.0.0.1:9000   ; 注释默认配置
  listen = 9000             ；这里是配置关键点

nginx 容器与PHP容器连接

容器之间网络默认使用 桥接 的方式连接
如果是K8S，nginx配置 fastcgi_pass 127.0.0.1:9000 这里不用修改

version: "3"
services:
    nginx-web:
        image: nginx:alpine
        container_name: nginx-web-server
        ports:
            - "80:80"
        depends_on:
            - php-fpm
        volumes:
            - ./web/:/usr/share/nginx/html/
            - ./default.conf:/etc/nginx/conf.d/default.conf
    php-fpm:
        image: wenba100xie/php:7.1-fpm-alpine-202008121444
        container_name: php-fpm-server
        expose:
            - 9000
        volumes:
            - ./web/:/usr/share/nginx/html/
            - ./www.conf:/usr/local/etc/php-fpm.d/www.conf

启动、关闭、查看日志

# 启动
docker-compose -f docker-compose.yaml up -d 
# 关闭
docker-compose -f docker-compose.yaml down --remove-orphans
# 查看日志
docker-compose -f docker-compose.yaml logs -f
