我正在尝试在 Docker 映像上设置 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 镜像使用这个命令：
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listen.allowed_clients = 127.0.0.1是因为否则我会收到拒绝连接的消息；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 映像将拥有什么 IP，而且这并不重要，因为我的 php-fpm 映像不会公开连接到互联网.
我跑去docker exec登录正在运行的镜像并跑去wget测试服务器：
root@428d78fd58df:/srv# wget 127.0.0.1:8000

控制台不显示任何输出，除了：
