我有一个从镜像“ php：7.2-apache”构建的docker容器。此官方图片默认使用 mpm_prefork 。我想使用 mpm_event 。然后，我执行了以下命令：
a2dismod mpm_prefork
a2enmod mpm_event
service apache2 reload
但是我收到以下错误消息：
[FAIL] Reloading Apache httpd web server: apache2 failed!
[warn] The apache2 configtest failed. Not doing anything. ... (warning).
Output of config test was:
