Recently I install the Bitnami WordPress on Apple MacBook Air M1, after WordPress setup finished, the error appeared after the Starting Apache
(95)Operation not supported: AH00023: Couldn’t create the mpm-accept mutex (95)Operation not supported: could not create accept mutex
Using a Dockerfile with the contents:
FROM bitnami/moodle # Some credit goes to: https://www.linode.com/community/questions/16977/server-fails-after-installing-certbot-mpm-run-failed-exiting#answer-66578 RUN echo 'Mutex posixsem' >>/opt/bitnami/apache2/conf/httpd.conf
worked for me on my Mac M1.
