[英]Can't connect to php7 fpm docker container from within an apache 2 docker container
[英]Multi Docker container with PHP7 fpm and nginx
我在设置多docker容器环境时遇到问题。 这个想法很标准:
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"]
Nginx更是如此:
FROM nginx
COPY conf.d/* /etc/nginx/conf.d/
conf.d
文件夹中只有一个文件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;
}
}
还有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
这种精确的设置可以在AWS Elastic Beanstalk上完美运行。 但是,在我的本地泊坞窗上,出现以下错误:
2016/11/17 09:55:36 [错误] 6#6:* 1((111:连接被拒绝)连接到上游时失败(111:连接被拒绝),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/ ”,主机:“ priz-local.com:8888” 172.17.0.1--[17 / Nov / 2016:09:55: 36 +0000]“ GET / HTTP / 1.1” 502575“-”“ Mozilla / 5.0(Macintosh; Intel Mac OS X 10_12_1)AppleWebKit / 537.36(KHTML,例如Gecko)Chrome / 54.0.2840.71 Safari / 537.36”“-”
更新如果我登录到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
我尝试过的另一件事是:
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;
}
}
该站点开始工作,但是所有资源(js | css | png | jpg | jpeg | gif | ico)现在都返回403
。
我想念什么?
经过与R0MANARMY的长时间交谈以及他的大量帮助,我认为我终于了解了问题的根源。
这里的主要问题是我没有使用Docker,因为它原本可以正常工作。
另一个原因是fpm不是Web服务器,并且代理到它的唯一方法是通过fastcgi(或者不是唯一的方法,但是在这种情况下,简单的proxy_pass不起作用)。
因此,正确的设置方法是:
fastcgi
为PHP脚本配置fastcgi
到php容器中 以下是一些有关如何执行此操作的示例:
http://geekyplatypus.com/dockerise-your-php-application-with-nginx-and-php7-fpm/
https://ejosh.co/de/2015/08/wordpress-and-docker-the-correct-way/
更新添加对我有用的实际解决方案:
为了加快周转时间,我决定使用docker-compose和docker-compose.yml用户,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在两个容器中都安装了完全相同的代码。 这样做的原因是因为fastcgi无法提供静态文件(至少据我了解),因此其想法是直接通过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;
}
}
因此,此配置通过php请求代理由fpm容器处理,而其他所有内容均取自本地安装的卷。
而已。 希望对您有所帮助。
仅有的几个问题:
http://localhost:9080
下载index.php文件而不是执行它
