Я пытаюсь запустить службу httpd на RHEL 7.
Когда я бегу systemctl start httpd, это не получается.
Вот вывод journalctl -xe. Нет явного сообщения об ошибке для httpd. Будут ли ошибки для polkitd влиять на apache? Как бы я решил это?

Вот вывод tail -f 10 /var/log/httpd/error_log. Файлы журнала хранятся в смонтированном каталоге NFS (размещенном удаленно). Я могу редактировать файлы с компьютера, на котором работает apache, но, похоже, сам apache не может писать в них.

To check if your system is utilizing SELinux:
# getenforce If the above returns enforcing, please continue:
# getsebool -a | grep httpd_use_nfs If the above returns httpd_use_nfs --> off, run the following command to permanently allow Apache to use NFS.
# setsebool -P httpd_use_nfs on Apache should be allowed to write to those error log files now.
