php-fpm,Nginx在分离的docker容器中，无法执行.php文件 - php-fpm & nginx in separated docker container, can not execute .php file

我想在一台机器上使用docker设置一个完全LNMP的环境。但是分离php-fpm &nginx容器。

我所做的是:

从docker中提取图像。io:

docker pull php:7.1-fpm
run with image:

docker run -d——name php-fpm -v/data/docker/php-fpm/configs/:/usr/local/etc/php-fpm。d -v/data/Docker/nginx/html:/var/www/html php:7.1-fpm

docker run -d——name nginx -v/data/docker/nginx/configs/:/etc/nginx -v/data/docker/nginx/html:/var/www/html -p 80:80——link php-fpm nginx

所有目录&文件有755个权限

配置文件如下:

nginx.conf

server {
    listen  80  default_server;
    server_name SkyEyeLab;
    root    /var/www/html;
    fastcgi_read_timeout 90;
    location ~ '.php {
    fastcgi_pass    php-fpm:9000;
    }
}

和php-fpm.conf(一些重要的配置部分):

listen 0.0.0.0:9000
listen.allowed_clients = any

然后我检查了nginx的环境&php-fpm:

[root@w-Lab01 ~]# docker ps

[root@w-Lab01 ~]# docker exec 6faf4a4b4f7e ping -c3 php-fpm

一切似乎都很好。然后我在/data/Docker/nginx/html下创建a.p p(它被挂载到nginx的/var/www/html目录)，内容如下:

<?php
phpinfo();
?>

然后在浏览器中访问http://localhost:80/a.php。但是我只得到一个空页面，我检查了nginx的access.log:

[root@w-Lab01 ~]# docker logs 6faf4a4b4f7e
220.181.171.120 - - [11/Oct/2016:10:25:11 +0000] "GET /a.php HTTP/1.1" 200 31 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:49.0) Gecko/20100101 Firefox/49.0"

似乎a.php是正确的解析&执行。但是为什么我不能看到phpinfo()结果在web浏览器

我修改了nginx的配置文件后:

server {
    listen  80  default_server;
    server_name SkyEyeLab;
    root    /var/www/html;
    fastcgi_read_timeout 90;
    location ~ '.php {
    fastcgi_pass    php-fpm:9000;
    }
}

server {
    listen  80  default_server;
    server_name SkyEyeLab;
    root    /var/www/html;
    fastcgi_read_timeout 90;
    location ~ '.php {
    fastcgi_pass    php-fpm:9000;
    include fastcgi.conf;
    }
}

一切顺利。

fastcgi.conf是环境配置文件。你可以检查nginx的配置目录(通常是/etc/nginx)，看看其中是否有fastcgi.conf或fastcgi_param。

也许，如果你想在nginx配置文件中使用"php-fpm"这个名字，你需要像这样链接容器:

docker run -d --name php-fpm -v /data/Docker/php-fpm/configs/:/usr/local/etc/php-fpm.d -v /data/Docker/nginx/html:/var/www/html php:7.1-fpm

之后:

 docker run -d --name nginx --link php-fpm:php-fpm -v /data/Docker/nginx/configs/:/etc/nginx -v /data/Docker/nginx/html:/var/www/html -p 80:80 --link php-fpm nginx
