如何通过unix套接字设置Apache2和PHP-FPM? [英] How to set up Apache2 and PHP-FPM via unix socket?

问题描述

我尝试通过unix套接字设置Apache2和PHP-FPM，但结果是

I try to set up Apache2 and PHP-FPM via unix socket but result is

(111)连接被拒绝:AH02454:FCGI:尝试连接到Unix域套接字/run/php/php7.2-fpm.sock(*)失败

(111)Connection refused: AH02454: FCGI: attempt to connect to Unix domain socket /run/php/php7.2-fpm.sock (*) failed

docker-compose.yml

docker-compose.yml

version: "2"
services:
    php:
        build: "php:7.2-rc-alpine"
        container_name: "php"
        volumes:
            - "./code:/usr/local/apache2/htdocs"
            - "./php7.2-fpm.sock:/run/php/php7.2-fpm.sock"
    apache2:
        build: "httpd:2.4-alpine"
        container_name: "apache2"
        volumes:
            - "./code:/usr/local/apache2/htdocs"
            - "./php7.2-fpm.sock:/run/php/php7.2-fpm.sock"
        ports:
            - 80:80
        links:
            - php

www.conf

listen = /run/php/php7.2-fpm.sock

httpd-vhosts.conf

httpd-vhosts.conf

<FilesMatch \.php$>
    SetHandler "proxy:unix:/run/php/php7.2-fpm.sock|fcgi://localhost/"
</FilesMatch>

但是通过TCP连接可以使用.

But it's work when connect via TCP.

www.conf

listen = 127.0.0.1:9000

httpd-vhosts.conf

httpd-vhosts.conf

<FilesMatch \.php$>
    SetHandler "proxy:fcgi://php:9000"
</FilesMatch>

推荐答案

好的，仓库也帮助解决了这个问题.

Okie, so have the repo helped to fix the issue.

问题1-将www.conf复制到apache容器中

您在apache容器Dockerfile中有以下声明

You had below statement in your apache container Dockerfile

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

这实际上是针对将运行php-fpm的php容器而不是apache容器

This is actually intended for the php container which will be running php-fpm and not the apache container

问题2-从未创建套接字

您的卷绑定- "./php7.2-fpm.sock:/run/php/php7.2-fpm.sock"正在创建套接字，而不是由php-fpm这样创建的.因此，您创建了一个空白文件，尝试连接到该文件不会执行任何操作

Your volume bind - "./php7.2-fpm.sock:/run/php/php7.2-fpm.sock" was creating the socket and they were not being created by php-fpm as such. So you created a blank file and trying to connect to it won't do anything

问题#3-php中没有用于创建套接字的配置

默认情况下，docker容器在fpm容器内创建侦听0.0.0.0:9000的功能.您需要覆盖容器内的zz-docker.conf文件来解决此问题.

The docker container by default create listen to 0.0.0.0:9000 inside the fpm container. You needed to override the zz-docker.conf file inside the container to fix the issue.

[global]
daemonize = no

[www]
listen = /run/php/php7.2-fpm.sock
listen.mode = 0666

更新的docker文件

Updated docker file

FROM php:7.2-rc-fpm-alpine

LABEL maintainer="Eakkapat Pattarathamrong ([e-mail])"
RUN docker-php-ext-install \
        sockets

RUN set -x \
        && deluser www-data \
        && addgroup -g 500 -S www-data \
        && adduser -u 500 -D -S -G www-data www-data

COPY php-fpm.d /usr/local/etc/php-fpm.d/

问题4-将套接字作为卷共享给主机

您应该使用命名卷共享套接字，因此套接字根本不应该在主机上.

You should be sharing sockets using a named volume, so the socket should not be on host at all.

version: "2"
services:
    php:
        build: "./php"
        container_name: "php"
        volumes:
            - "./code:/usr/local/apache2/htdocs"
            - "phpsocket:/run/php"
    apache2:
        build: "./apache2"
        container_name: "apache2"
        volumes:
            - "./code:/usr/local/apache2/htdocs"
            - "phpsocket:/run/php"
        ports:
            - 7080:80
        links:
            - php
volumes:
  phpsocket:

解决所有问题后，我能够使php页面正常工作

After fixing all the issues I was able to get the php page working
