php - 如何在docker中使用unix套接字将nginx连接到php-fpm

Question

这是我的 docker-compose.yml

version: '2'

services:
    web:
        image: nginx:latest
        ports:
            - "8018:80"
        volumes:
            - ./code:/code
            - ./site.conf:/etc/nginx/conf.d/default.conf
            - /private/var/log/nginx:/var/log/nginx
            - /private/var/run/php7-fpm.sock:/var/run/php7-fpm.sock
        networks:
            - code-network
    php:
        image: php:fpm
        volumes:
            - ./code:/code
            - ./php-fpm.conf:/usr/local/etc/php-fpm.conf
            - ./www.conf:/usr/local/etc/php-fpm.d/www.conf
            - /private/var/run/php7-fpm.sock:/var/run/php7-fpm.sock
        networks:
            - code-network

networks:
    code-network:
        driver: bridge

并且在site.conf中我这样写fastcgi_pass unix:/var/run/php7-fpm.sock;我也把监听地址改成listen =/var/run/php7-fpm.sock 在 www.conf.在我的 MAC 中，文件夹/private/var/run 中有一个名为 php7-fpm.sock 的文件，模式为 666

在我运行 docker-compose up -d 之后，容器运行成功。但是当我访问 http://localhost:8018 时，返回502，我查看nginx错误日志后，发现了这个

2017/11/01 13:08:39 [error] 6#6: *1 connect() to unix:/var/run/php7-fpm.sock failed (111: Connection refused) while connecting to upstream, client: 172.18.0.1, server: localhost, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/var/run/php7-fpm.sock:", host: "localhost:8018"

顺便说一句，在我尝试使用 unix 套接字模式之前。我访问成功http://localhost:8018使用 tcp/ip 模式。

在我检查了How to set up Apache2 and PHP-FPM via unix socket?之后，我将 docker-compose.yml 更改为

version: '2'

services:
    web:
        image: nginx:latest
        ports:
            - "8018:80"
        volumes:
            - ./code:/code
            - ./site.conf:/etc/nginx/conf.d/default.conf
            - /private/var/log/nginx:/var/log/nginx
            - "phpsocket:/var/run"
        networks:
            - code-network
    php:
        image: php:fpm
        volumes:
            - ./code:/code
            - ./php-fpm.conf:/usr/local/etc/php-fpm.conf
            - ./www.conf:/usr/local/etc/php-fpm.d/www.conf
            - ./zz-docker.conf:/usr/local/etc/php-fpm.d/zz-docker.conf
            - "phpsocket:/var/run"
        networks:
            - code-network

networks:
    code-network:
        driver: bridge

volumes:
    phpsocket:

并覆盖 zz-docker.conf 到

[global]
daemonize = no

[www]
listen = /var/run/php7-fpm.sock
listen.mode = 0666

终于当我访问了http://localhost:8018 , phpinfo 页面出现了!
