php-fpm 连接被对端重置

Question

我正在尝试在 Docker 图像上设置 php-fpm。

这是我的 docker-compose.yml 中的服务：

wordpress-service:
  build:
    context: .
    dockerfile: Dockerfile-wordpress
  image: riffsy-web-wordpress:latest
  restart: always
  links:
   - wordpress-mysql
  depends_on:
   - wordpress-mysql
  expose:
    - "8000"
  environment:
   - DB_NAME=wordpress
   - DB_USER=wordpress
   - DB_PASSWORD=password123
   - DB_HOST=wordpress-mysql
   - DB_PORT=3306
  ports:
   - "8000:8000"

Docker 图像使用此命令：

CMD php-fpm7.0 --fpm-config /etc/php-fpm.conf

这是我的 php-fpm 配置文件：

[global]

error_log = /dev/stderr
log_level = debug
daemonize = no

[www]
listen = 8000
listen.allowed_clients = 127.0.0.1
user = www-data
group = www-data
pm = dynamic
pm.max_children = 6
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 4
pm.max_requests = 500
request_terminate_timeout = 120s
catch_workers_output = yes

我设置了 listen.allowed_clients = 127.0.0.1 因为否则我会收到连接被拒绝的消息；最终我需要 php-fpm 来接受来自任何 IP 的连接，因为我不知道我的 Nginx 图像将具有什么 IP，而且这并不重要，因为我的 php-fpm 图像赢了'公开连接到互联网。

我运行 docker exec 登录运行图像和运行 wget 测试服务器：

root@428d78fd58df:/srv# wget 127.0.0.1:8000                           
--2016-09-12 07:55:13--  http://127.0.0.1:8000/
Connecting to 127.0.0.1:8000... connected.
HTTP request sent, awaiting response... Read error (Connection reset by peer) in headers.
Retrying.

--2016-09-12 07:55:14--  (try: 2)  http://127.0.0.1:8000/
Connecting to 127.0.0.1:8000... connected.
HTTP request sent, awaiting response... Read error (Connection reset by peer) in headers.
Retrying.

--2016-09-12 07:55:16--  (try: 3)  http://127.0.0.1:8000/
Connecting to 127.0.0.1:8000... connected.
HTTP request sent, awaiting response... Read error (Connection reset by peer) in headers.
Retrying.

^C

除了以下内容，控制台没有显示任何输出：

wordpress-service_1  | [12-Sep-2016 08:01:09.757039] DEBUG: pid 5, fpm_pctl_perform_idle_server_maintenance(), line 379: [pool www] currently 0 active children, 2 spare children, 2 running children. Spawning rate 1

Answer 1

问题是php-fpm没有使用http协议，它使用fastcgi。连接它的唯一方法是将 Nginx 设置为使用 fastcgi。
