如何使用docker中的unix socket将nginx连接到php-fpm教程

有我的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

在site.conf中我写了这样的fastcgi\_pass unix：/var/run/php7-fpm.sock;我还在www.conf中将listen地址改为listen = /var/run/php7-fpm.sock.
在我的MAC中,文件夹/ p​​rivate / var / run中有一个名为php7-fpm.sock的文件,模式为666

在我运行docker-compose -d之后,容器运行成功.但是当我访问http://localhost:8018时,它返回502.在我检查了nginx错误日志后,我发现了这个

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.我成功用tcp / ip模式访问http://localhost:8018.

解决方法:

检查How to set up Apache2 and PHP-FPM via unix socket?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

[global]
daemonize = no

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

最后当我访问http://localhost:8018时,phpinfo页面出现了！
