我想做一个完全停靠的Drupal安装.我的第一步是使用基于Debian的Nginx和php5-fpm运行容器.我在CoreOS alpha频道上(使用Digital Ocean.)

我的Dockerfiles如下:

Nginx的:

FROM debian
MAINTAINER fvhemert
RUN apt-get update && apt-get install -y nginx && echo "\ndaemon off;" >> /etc/nginx/nginx.conf
CMD ["nginx"]
EXPOSE 80

这个容器构建并运行良好.我在服务器ip上看到默认的Nginx页面.

PHP5-FPM:

FROM debian
MAINTAINER fvhemert
RUN apt-get update && apt-get install -y \
            php5-fpm \
            && sed 's/;daemonize = yes/daemonize = no/' -i /etc/php5/fpm/php-fpm.conf
CMD ["php5-fpm"]
EXPOSE 9000

此容器也可以构建没有问题,并在启动时保持运行.

我首先启动php5-fpm容器:

docker run -d --name php5-fpm freek/php5-fpm:1

广告然后我开始Nginx ,,链接到php5-fpm:

docker run -d -p 80:80 --link php5-fpm:phpserver --name nginx freek/nginx-php:1

链接似乎工作,在/ etc/hosts中有一个名为phpserver的条目.两个码头工人都跑:

core@dockertest ~ $ docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                NAMES
fd1a9ae0f1dd        freek/nginx-php:4   "nginx"             38 minutes ago      Up 38 minutes       0.0.0.0:80->80/tcp   nginx
3bd12b3761b9        freek/php5-fpm:2    "php5-fpm"          38 minutes ago      Up 38 minutes       9000/tcp             php5-fpm

我已经调整了一些配置文件.对于Nginx容器,我编辑了/ etc/nginx/sites-enabled/default并更改了:

server {
        #listen   80; ## listen for ipv4; this line is default and implied
        #listen   [::]:80 default_server ipv6only=on; ## listen for ipv6

        root /usr/share/nginx/www;
        index index.html index.htm index.php;

(我添加了index.php)

进一步说:

location ~ \.php$ {
                fastcgi_split_path_info ^(.+\.php)(/.+)$;
        #       # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
        #
        #       # With php5-cgi alone:
                fastcgi_pass phpserver:9000;
        #       # With php5-fpm:
        #       fastcgi_pass unix:/var/run/php5-fpm.sock;
                fastcgi_index index.php;
                include fastcgi_params;
        }

在php5-fpm docker中我更改了/etc/php5/fpm/php.ini:

cgi.fix_pathinfo=0

php5-fpm运行:

[21-Nov-2014 06:15:29] NOTICE: fpm is running, pid 1
[21-Nov-2014 06:15:29] NOTICE: ready to handle connections

我还将index.html更改为index.php,它看起来像这样(/usr/share/nginx/www/index.php):

Welcome to nginx!

我已经从Nginx docker扫描了9000端口,它显示为已关闭.当然不是一个好兆头:

root@fd1a9ae0f1dd:/# nmap -p 9000 phpserver

Starting Nmap 6.00 ( http://nmap.org ) at 2014-11-21 06:49 UTC

Nmap done: 1 IP address (1 host up) scanned in 0.13 seconds

Nginx日志:

root@fd1a9ae0f1dd:/# vim /var/log/nginx/error.log

是的,那是错误的,当我浏览到我的Nginx实例时,我不断收到502错误的网关错误.

我的问题是:究竟出了什么问题？我的猜测是我错过了php配置文件中的一些设置.

编辑更多细节:这是结果(来自php5-fpm容器内部,在apt-get install net-tools之后):

root @ 3bd12b3761b9:/ #netstat -tapen
活动Internet连接
(服务器和已建立)Proto Recv-Q Send-Q本地地址

从Nginx容器内部:

root @ fd1a9ae0f1dd:/ #netstat -tapen

EDIT2:进步!

在php5-fpm容器中,在文件中:

/etc/php5/fpm/pool.d/www.conf

我将listen参数从某个套接字名称更改为:

listen = 9000

现在当我进入我的网页时,我收到错误:"没有指定输入文件."

可能我在某处有尾随/错误.我会仔细研究一下!

EDIT3:

所以我用上面提到的改动重建了码头工人,似乎他们正在谈论.但是,我的网页告诉我:"找不到文件." 我非常肯定它与nginx发送到php-fpm的文件有关,但我不知道它应该是什么样子.我在使用始终有效的套接字方法时使用了默认值.现在它不再起作用了.什么应该在/ etc/nginx/sites-enabled/default下位置〜.php $ {？
