Alpine php fpm配置出现问题（xdebug+；netbeans、sendmail+；mailhog）

我试图为一个PHP应用程序设置开发环境，但我无法解决这两件事：

• 发送电子邮件（我想使用正在运行的MailHog，但似乎我没有正确的PHP配置）
• xdebug（已安装且日志正在运行，但我无法从NetBeans IDE连接它）

以下是我的配置：

docker compose.yml:

我在页面上找到了这个问题的mailhog“拒绝连接”部分的解决方案。您需要替换邮件中的

sendmail\u path

语句 docker/php fpm/php.ini，类似于以下内容（不支持-S选项，引号的位置很重要）：

---

我还发现我不需要使用

命令

，

user

或

expose

docker compose文件中的mailhog服务部分。

目前，我尝试使用

docker exec-it php-fpm_1 bash直接连接到php fpm容器

，并尝试从命令行使用mhsendmail直接发送电子邮件，但是我得到了

。。。有什么帮助吗？
