Let's say your Apache web server log has something like this.

AH01238: cgid daemon failed to initialize

When I first happened upon this, I saw the prior event in the log.

[Wed Feb 28 21:24:00.740223 2024] [cgid:error] [pid 9340:tid 140107356956480] (2)No such file or directory: AH01243: Couldn't bind unix domain socket /opt/Apache/logs/logs/cgisocklab.lab8501.9338

And when I checked the Apache web servers configuration file, I saw the Scriptsock directive had "logs/cgisocket" which resulted in pointing to an invalid directory (/opt/Apache/logs/logs/cgisocklab.lab8501).

Scriptsock logs/cgisocklab.lab8501

The solution was simple. I stopped the Apache web server instance.

<web_server_root>/bin/apachectl -k stop -f conf/instance.conf

Then updated the Scriptsock directive in the Apache web servers configuration file.

Scriptsock cgisocklab.lab8501

Then I started the Apache web server instance and I no longer was seeing "AH01238: cgid daemon failed to initialize" in the log.

<web_server_root>/bin/apachectl -k start -f conf/instance.conf
