具有PHP7 fpm和nginx

我在设置多Docker容器环境时遇到问题。 这个想法很标准:

  • 一个容器运行php-fpm
  • 另一个是nginx代理

我的phpfpm Docker文件非常简单:

FROM php:7.0-fpm

# install the PHP extensions we need
RUN apt-get update && apt-get install -y libpng12-dev libjpeg-dev && rm -rf /var/lib/apt/lists/* \
    && docker-php-ext-configure gd --with-png-dir=/usr --with-jpeg-dir=/usr \
    && docker-php-ext-install gd mysqli opcache

# set recommended PHP.ini settings
# see https://secure.php.net/manual/en/opcache.installation.php
RUN { \
        echo 'opcache.memory_consumption=128'; \
        echo 'opcache.interned_strings_buffer=8'; \
        echo 'opcache.max_accelerated_files=4000'; \
        echo 'opcache.revalidate_freq=2'; \
        echo 'opcache.fast_shutdown=1'; \
        echo 'opcache.enable_cli=1'; \
    } > /usr/local/etc/php/conf.d/opcache-recommended.ini

VOLUME /var/www/html

CMD ["php-fpm"]

和Nginx更是如此:

FROM nginx

COPY conf.d/* /etc/nginx/conf.d/

conf.d文件夹内的单个文件default.conf

server {
    listen 80;
    server_name priz-local.com;
    root /var/www/html;

    index index.php;

    location / {
        proxy_pass  http://website:9000;
        proxy_set_header   Connection "";
        proxy_http_version 1.1;
        proxy_set_header        Host            $host;
        proxy_set_header        X-Real-IP       $remote_addr;
        proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

和docker-compose.yml

website:
  build: ./website/
  ports:
   - "9000:9000"
  container_name: website
  external_links:
     - mysql:mysql
nginx-proxy:
  build: ./proxy/
  ports:
    - "8000:80"
  container_name: proxy
  links:
       - website:website

此精确设置在AWS Elastic Beanstalk上完美运行。但是,在我的本地docker上,我收到的错误如下:

  

2016/11/17 09:55:36 [错误] 6#6:* 1 connect()失败(111:连接   拒绝)连接上游时,客户端:172.17.0.1,服务器:   priz-local.com,请求:" GET / HTTP / 1.1",上游:   " http://127.0.0.1:9000/",主持人:" priz-local.com:8888"   172.17.0.1 - - [17 / Nov / 2016:09:55:36 +0000]" GET / HTTP / 1.1" 502 575" - " " Mozilla / 5.0(Macintosh; Intel Mac OS X 10_12_1)   AppleWebKit / 537.36(KHTML,与Gecko一样)Chrome / 54.0.2840.71   Safari浏览器/ 537.36" " - "

更新 如果我登录代理容器并尝试卷曲到另一个我得到这个:

root@4fb46a4713a8:/# curl http://website
curl: (7) Failed to connect to website port 80: Connection refused
root@4fb46a4713a8:/# curl http://website:9000
curl: (56) Recv failure: Connection reset by peer

我尝试的另一件事是:

server {
    listen 80;
    server_name priz-local.com;
    root /var/www/html;

    #index index.php;
    #charset UTF-8;

    #gzip on;
    #gzip_http_version 1.1;
    #gzip_vary on;
    #gzip_comp_level 6;
    #gzip_proxied any;
    #gzip_types text/plain text/xml text/css application/x-javascript;

    location = /robots.txt {
        allow all;
        log_not_found off;
        access_log off;
    }

    location /nginx_status {
        stub_status on;
        access_log off;
    }

    location / {
        try_files $uri $uri/ /index.php?q=$uri&$args;
    }

    location ~ \.php$ {

        set $nocache "";
        if ($http_cookie ~ (comment_author_.*|wordpress_logged_in.*|wp-postpass_.*)) {
           set $nocache "Y";
        }

        fastcgi_pass  website:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_intercept_errors on;
        include fastcgi_params;

        #fastcgi_cache_use_stale error timeout invalid_header http_500;
        #fastcgi_cache_key $host$request_uri;
        #fastcgi_cache example;
        #fastcgi_cache_valid 200 1m;
        #fastcgi_cache_bypass $nocache;
        #fastcgi_no_cache $nocache;
    }

    location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
        allow all;
        expires max;
        log_not_found off;

        fastcgi_pass  wordpress:9000;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_intercept_errors on;
        include fastcgi_params;
    }
}

网站开始运作,但所有资源(js | css | png | jpg | jpeg | gif | ico)现在都返回403

我错过了什么?

1 个答案:

答案 0 :(得分:0)

在与R0MANARMY进行了很长时间的聊天并得到了很多帮助后,我想我终于理解了问题的根源。

这里的主要问题是我没有使用docker,因为它打算工作。

另一个原因是fpm不是网络服务器,而代理它的唯一方法是通过fastcgi(或者可能不是唯一的,但简单的proxy_pass在这种情况下不起作用)。

因此,正确的设置方法是:

  1. 将代码卷安装到两个容器中。
  2. 通过nginx为php脚本配置fastcgi到php容器
  3. 配置虚拟主机以直接通过nginx提供静态资产。
  4. 以下是一些如何操作的示例:

    <强>更新 添加对我有用的实际解决方案:

    为了更快的周转时间,我决定使用docker-compose和docker-compose.yml,如下所示:

    website:
      build: ./website/
      container_name: website
      external_links:
        - mysql:mysql
      volumes:
        - ~/Dev/priz/website:/var/www/html
      environment:
        WORDPRESS_DB_USER: **
        WORDPRESS_DB_PASSWORD: ***
        WORDPRESS_DB_NAME: ***
        WORDPRESS_DB_HOST: ***
    proxy:
      image: nginx
      container_name: proxy
      links:
        - website:website
      ports:
        - "9080:80"
      volumes:
        - ~/Dev/priz/website:/var/www/html
        - ./deployment/proxy/conf.d/default.conf:/etc/nginx/conf.d/default.conf
    

    现在,这里最重要的信息是我将两个容器安装完全相同的代码。原因是因为fastcgi不能提供静态文件(至少据我所知),所以想法是直接通过nginx提供服务。

    我的default.conf文件如下所示:

    server {
        listen 80;
        server_name localhost;
        root /var/www/html;
    
        index index.php;
    
        location = /robots.txt {
            allow all;
            log_not_found off;
            access_log off;
        }
    
        location /nginx_status {
            stub_status on;
            access_log off;
        }
    
        location / {
            try_files $uri $uri/ /index.php?q=$uri&$args;
        }
    
        location ~ \.php$ {
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_pass website:9000;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            #fastcgi_param PATH_INFO $fastcgi_path_info;
            fastcgi_intercept_errors on;
            include fastcgi_params;
        }
    }
    

    所以,这个配置,代理通过php请求由fpm容器处理,而其他一切都是从本地安装的卷中获取。

    就是这样。我希望它会帮助别人。

    唯一的问题是:

    1. 有时只有http://localhost:9080下载index.php文件而不是执行它
    2. cURL从php脚本到外界,需要很长时间才能确定如何调试它,此时。
