I updated httpd to version 2.4.57. I compiled httpd on my own and when I start httpd within a chroot environment, I am getting this error message in the logs:
[Thu Jun 22 14:33:27.319378 2023] [slotmem_shm:error] [pid 3591] (13)Permission denied: AH02611: create: apr_shm_create(/log/slotmem-shm-p24af65f1_0.shm) failed
[Thu Jun 22 14:33:27.319470 2023] [proxy_balancer:emerg] [pid 3591] (13)Permission denied: AH01179: balancer slotmem_create failed
[Thu Jun 22 14:33:27.319477 2023] [:emerg] [pid 3591] AH00020: Configuration Failed, exiting
In my httpd.conf there is this part where I define the value of DefaultRuntimeDir:
<IfDefine !DEV>
DefaultRuntimeDir /log
</IfDefine>
And this are my rights on that directory:
drwxrwxrwx 4 web web 4096 Jun 22 13:32 log
What I am missing here?
Edit
I tried to trace with strace which files are accessed during startup of httpd (open and write events) and I found this line:
6579 open("/dev/shm/ShM.fc123de7H42c92a7", O_RDWR|O_CREAT|O_EXCL|O_NOFOLLOW|O_CLOEXEC, 0644) = -1 EACCES (Permission denied)
Checking the rights within my chroot environment of /dev/shm I get this output
drwxr-xr-x 2 root root 40 Jun 22 16:58 shm
But I am not sure if that is correct or what I can change here.
