The main content of this article is to explain "Apache startup error report No space left on device: AH00023 solution", interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn "Apache startup error report No space left on device: the solution of AH00023"!

Apache startup error No space left on device: AH00023 error may be caused by the process, although the editor does not know the reason, but the online solution can really solve our problem, let's take a look.

This type of error is caused by the ipc semaphore of the linux system, and when apache starts, many child processes are created. They communicate with child processes through semaphores.

Semaphore introduction:

Semaphores, also known as semaphores, are used to coordinate data objects between different processes, and the main application is inter-process communication in shared memory. In essence, a semaphore is a counter that records access to a resource, such as shared memory, which is the fastest way to communicate between processes running on the same machine, because data does not need to be copied between different processes. Usually a shared memory area is created by one process, and the other processes read and write to this memory area. Under the Linux system, the common way is to use the shared memory to store through the shmXXX function family.

Solution:

/ etc/init.d/httpd stop stop apache service

For i in ipcs-s | awk'/ apache startup process user / {print $2}'; do (ipcrm-s $I); done

/ etc/init.d/httpd start starts apache

Later, a solution on the Internet is also sorted out for your reference.

AH00016: Configuration Failed

Ipcs-s | grep apache | awk'{print $2}'| xargs-n 1 ipcrm- http://www.iis7.com/b/ssyqdq/

Ipcs-s | grep web | perl-e 'while () {@ a=split (/\ slots /); print ipcrm sem $a [1]}'

At this point, I believe you have a deeper understanding of "Apache startup error report No space left on device: AH00023 solution". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
