Setiap kali server di-reboot, direktori / run / httpd dihapus. / run adalah sistem file tmpfs, oleh karena itu, dipasang di RAM.
/ run / httpd dibuat hanya selama instalasi. Ketika saya memulai httpd setelah reboot, direktori tidak dibuat ulang.
Server telah menginstal CentOS 7 dan paket Apache repositori oficial (v. 2.4.6-18).
Setelah Apache menginstal dan memulai, direktori adalah sebagai berikut:
# 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 ..
Tetapi setelah reboot:
# ls -l /run/httpd
ls: cannot access /run/httpd: No such file or directory
Dan inilah log ketika mencoba me-restart Apache:

Ketika saya membuat direktori secara manual, Apache memulai:
# mkdir /run/httpd
# systemctl restart httpd
# ls -lRa /run/httpd/
/run/httpd/:
total 8
drwxr-xr-x. 2 root root 100 Sep 30 09:36 .

-rw-r--r--. 1 root root 5 Sep 30 09:36 httpd.pid
srwx------. 1 apache root 0 Sep 30 09:36 wsgi.3452.0.1.sock
Dan setelah reboot, itu hilang lagi.
Adakah pemikiran mengapa ini terjadi?
