“Hello World”与官方的nginx和php码头图像。如何？ [英] "Hello World" with official nginx and php docker images. Howto?

问题描述

我想运行一些简单的index.php文件，使用官方的nginx和php docker图像。这些是我的先决条件：

I want to run some simple index.php file, using official nginx and php docker images. These are my prerequisites:

1. ubuntu版本是16.04.1 LTS（我的主机）


2. docker版本是1.12.6


3. docker-compose版本1.9.0

我的本​​地目录在我的主机上看起来像这样：

My local directory on my host machine looks like so:

\code
    index.php
docker-compose.yml
nginx.conf

index.php包含一些简单的代码：

index.php contains some simple code:

<?php
    echo phpinfo();
?>

docker-compose.yml包含这些说明（版本1）：

docker-compose.yml contains these instructions (version 1):

web:
    image: nginx:latest
    ports:
        - "8181:80"
    volumes:
        - ./code:/code
        - ./nginx.conf:/etc/nginx/nginx.conf
    links:
        - php

php:
    image: php:7-fpm
    volumes:
        ./code:/code

nginx.conf包含这些说明（版本1）：

nginx.conf contains these instructions (version 1):

worker_processes 1
events { worker_connections 1024; }
http {
    sendfile on;
    server {
        listen 80;
        index index.php index.html;
        root /code;

        location ~ \.php$ {
            try_files $uri =404;
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_pass php:9000;
            fastcgi_index index.php;
            include fastcgi_params;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            fastcgi_param PATH_INFO $fastcgi_path_info;
        }

    }
}

我运行命令：

docker-compose up --force-recreate

我在控制台中看到这两个图像都是创建的，但是当我转到本地主机时：8181，我收到一条错误消息。这是错误信息的全文：

I see in the console that both images are created, however, when I go to localhost:8181, I get an error message. This is the full text of the error message:

* 1未找到/etc/nginx/html/index.php 2：没有这样的文件或目录），客户端：172.17.0.1，服务器：请求：GET / HTTP / 1.1，主机：localhost：8181

*1 "/etc/nginx/html/index.php" is not found (2: No such file or directory), client: 172.17.0.1, server: , request: "GET / HTTP/1.1", host: "localhost:8181"

我真的很奇怪，为什么在 / etc / nginx / html / 文件夹中搜索，忽略 root / code; / code>指令从nginx.conf文件。然而，我编辑docker-compose.yml，现在看起来像这样：

I really wonder, why it searches in /etc/nginx/html/ folder and ignores root /code; instruction from nginx.conf file. Nevertheless, I edit docker-compose.yml, so that it now looks like so:

web:
    image: nginx:latest
    ports:
        - "8181:80"
    volumes:
        - ./code:/etc/nginx/html
        - ./nginx.conf:/etc/nginx/nginx.conf
    links:
        - php

php:
    image: php:7-fpm
    volumes:
        ./code:/code

如你所见，我已经改变了一个指令网页/卷：

As you can see, I've changed just one instruction under web/volumes:

./code:/code -> ./code:/etc/nginx/html

现在，当我重新运行 docker-compos up --force-recreate 并转到localhost：8181我看到另一个错误信息：

Now, when I rerun docker-compose up --force-recreate and go to localhost:8181 I see another error message:

FastCGI在stderr中发送：主脚本未知，同时从上游读取响应头，客户端：172.17.0.1，server：请求：GET / HTTP / 1.1，上游：fastcgi：//172.17.0.2：9000主持人：localhost：8181

FastCGI Sent in stderr: "Primary script unknown" while reading response header from upstream, client: 172.17.0.1, server: , request: "GET / HTTP/1.1" , upstream : "fastcgi://172.17.0.2:9000", host: "localhost:8181"

现在我不知道这一切是什么意思。之后，我在nginx.conf中尝试了许多不同的指令组合，但是每当我完成相同的错误消息时，它都会失败。那么我的问题是如何让它工作？ Docker-compose.yml和nginx.conf应该如何在ordrer中看起来像在世界上运行最简单的脚本？

Now I do not know what it all means. After that I tried many different combinations of instructions in nginx.conf, but it each time I ended in failure with the exact same error message. So, my question is how can I make it work? How docker-compose.yml and nginx.conf should look like in ordrer to be able to run the simplest script in the world?

推荐答案

p>您的php容器卷定义中缺少 - 。

You have a missing "-" in your php container volume definition.

php:
    image: php:7-fpm
    volumes:
        ./code:/code

应该是：

php:
    image: php:7-fpm
    volumes:
        - ./code:/code

我自己测试过，并且通过该修正可以正常工作：

I tested it myself and with that correction it works fine:

Starting test_php_1
Starting test_web_1
Attaching to test_php_1, test_web_1
php_1  | [19-Jan-2017 14:41:09] NOTICE: fpm is running, pid 1
php_1  | [19-Jan-2017 14:41:09] NOTICE: ready to handle connections
web_1  | 172.17.0.1 - - [19/Jan/2017:14:41:39 +0000] "GET / HTTP/1.1" 200 82883 "-" "curl/7.35.0"
