Internal server error di VPS Centos 7

Saya telah selesai membuat website di localhost, tetapi ketika upload ke server online terjadi internal server error 500. Berikut keterangan dari error_log nya :

[:error] [pid 1390:tid 140589941106432] [client xxx.xxx.xxx] SoftException in Application.cpp:542: Could not execute script "/home/tripnme/laravel/public/index.php" [:error] [pid 1390:tid 140589941106432] [client xxx.xxx.xxx] Caused by SystemException in API_Linux.cpp:444: execve() for program "/usr/local/bin/php-cgi" failed: No such file or directory [core:error] [pid 1390:tid 140589941106432] [client xxx.xxx.xxx] End of script output before headers: index.php

Mohon bantuannya kira" kenapa dan apa saja yang harus saya cek

Terimakasih
