[ASK] Kloxo-MR 7 dengan CentOS 7 dan Rekomendasi Setting

[jamalrahmat]

Selamat siang Mas Mustafa...

Saya mau tanya mengenai Kloxo-MR 7 dengan CentOS 7. Saat ini saya sedang menangani satu server lokal pemerintahan untuk dijadikan webhosting.

Server: HP ProLiant DL360p Gen8
CPU: 6 cores
RAM: 16GB
ISP: Astin*t 6Mbps

Berikut hasil sysinfo...

   7. Stats: awstats
D. Memory:
              total        used        free      shared  buff/cache   available
Mem:          15845         455       14817          55         572       15007
Swap:          8063           0        8063
E. Disk Space:
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda3        50G  3.6G   44G   8% /

Untuk instalasi saya menggunakan:
- 250GB SSD (ext4 - /dev/sda) untuk root (50GB), swap (8GB), home (sisanya), dll.
- 1TB HDD (ext4 - /dev/sdb) khusus untuk tempat backup.

Pertanyaan:
1. Berapa maksimum fastcgi children untuk 1 klien? Anggap saja max 20 - 30 klien.
2. Bagaimana cara mengatur RDNS? Karena biasanya kalau VPS ya setting di SolusVM. Kalau ini setting kemana ya? BIND atau menghubungi pihak ISP?
3. Bagaimana cara backup Kloxo-MR otomatis atau /home secara otomatis dari SSD ke HDD? Apakah ada cron yang harus disetting?
4. Ketika restart service ada error seperti ini. Salah dimana ya?

Redirecting to /bin/systemctl restart  rsyslog.service

Restarting httpry (via systemctl):  Job for httpry.service failed because a configured resource limit was exceeded. See "systemctl status httpry.service" and "journalctl -xe" for details.

Mungkin itu saja dulu....

Sebelumnya saya ucapkan terima kasih untuk supportnya

1. Sebaiknya partisi anda adalah:
- /boot -> 256MB
- swap -> 4GB
- ROOT -> sisanya

Jadi tanpa partisi /home yang akan bermasalah nanti-nantinya

2. Total fastcgi_children untuk server anda bisa 256-512 (tergantung traffic masing-masing client). Ini memungkinkan setiap client diset sebesar 24 secara rata-rata

3. RDNS (reverse-dns) biasanya minta ke provider kecuali ada setting di vps panel. Kadangkala RDNS juga disebut PTR

4. Soal error pada httpry saya belum pernah menemukan seperti ini. Abaikan saja dulu

Terima kasih atas jawabannya Pak...

Ini saya sertakan log dari httpry yang failed ketika restart.

systemctl status httpry.service -l
