Alpine php-fpm 配置(xdebug+netbeans、sendmail+mailhog)的问题

Question

我正在尝试为一个PHP应用程序设置开发环境，但我无法解决以下两件事：

• 发送电子邮件(我想使用正在运行的 MailHog，但似乎我没有更正 PHP 配置)
• xdebug(已安装并且日志正在工作，但我无法从NetBeans IDE连接它)

这是我的配置：

docker-compose.yml：

version: "3.1"
services:
# MySQL

MYSQL_ROOT_PASSWORD: root
MYSQL_USER: testuser
MYSQL_PASSWORD: testpass
MYSQL_DATABASE: testdb

Answer 1

我在mailhog github问题页面上找到了这个问题的mailhog"连接被拒绝"部分的解决方案。您需要替换sendmail_path语句 docker/php-fpm/php.ini 带有这样的东西(不支持 -S 选项，引号的位置很重要)：

sendmail_path = "/usr/bin/mhsendmail --smtp-addr=mailhog:1025"

我还发现我不需要在docker-compose文件中使用mailhog服务部分的command，user或expose部分。
