php-fpm Tuning

Target 1000 concurrent users untuk TAO

CPU 


CPU 10 core

$ cat /proc/cpuinfo | grep "model name"

model name : Intel(R) Xeon(R) Gold 5115 CPU @ 2.40GHz
model name : Intel(R) Xeon(R) Gold 5115 CPU @ 2.40GHz

Memory 

$free -g
              total        used        free      shared  buff/cache   available
Mem:             16           0          14           0           1          15
Swap:             0           0           0

Tuning

MySQL menggunakan konfigurasi seperti di jelaskan ... disini ..., Ketika concurent user 16 s.d 27, ke website utama, bukan TAO, MySQL memakan memory kurang lebih 800M s.d 900M.

Untuk mengetahui concurrent user, jalankan perintah : 

 $ netstat -plan | grep :80 | wc -l
 $ netstat -plan | grep :443 | wc -l


Terkadang, tiba-tiba server seperti hang tidak bisa menerima request sama sekali, menurut diskusi [7], solusi yg bisa dicoba mengubah kongurasi php-fpm.conf

emergency_restart_threshold=3

emergency_restart_interval=1m

process_control_timeout=5s
