Cada vez que se reinicia el servidor, se elimina el directorio / run / httpd. / run es un sistema de archivos tmpfs, por lo tanto, montado en RAM.
/ run / httpd se crea solo durante la instalación. Cuando inicio httpd después de reiniciar, el directorio no se vuelve a crear.
El servidor ha instalado CentOS 7 y el paquete oficial del repositorio Apache (v. 2.4.6-18).
Después de instalar e iniciar Apache, el directorio es el siguiente:
# ls -alR /run/httpd/
/run/httpd/:
total 8
drwx--x---. 3 root apache 120 Sep 30 08:39 .
drwxr-xr-x. 28 root root 1020 Sep 30 08:37 ..
-rw-r--r--. 1 root root 8 Sep 30 08:39 authdigest_shm.2953
drwx------. 2 apache apache 40 Jul 23 10:48 htcacheclean
-rw-r--r--. 1 root root 5 Sep 30 08:39 httpd.pid
srwx------. 1 apache root 0 Sep 30 08:39 wsgi.2953.0.1.sock
/run/httpd/htcacheclean:
total 0
drwx------. 2 apache apache 40 Jul 23 10:48 .
drwx--x---. 3 root apache 120 Sep 30 08:39 ..
Pero después de reiniciar:
# ls -l /run/httpd
ls: cannot access /run/httpd: No such file or directory
Y aquí están los registros al intentar reiniciar Apache:

Cuando creo el directorio manualmente, Apache comienza:
# mkdir /run/httpd
# systemctl restart httpd
# ls -lRa /run/httpd/
/run/httpd/:

srwx------. 1 apache root 0 Sep 30 09:36 wsgi.3452.0.1.sock
Y después de reiniciar, se ha ido de nuevo.
¿Alguna idea de por qué está sucediendo esto?
