Meu servidor cents 6.7 possui apenas meus sites de baixo tráfego baseados em php e mysql (totalizam cerca de 3000 visualizações de páginas por dia para todos os sites) usando o servidor nginx e virtualmin (sem wordpress ou scripts externos / software).
Eu instalei o PHP com:
yum --enablerepo=remi,remi-php56 install -y php-mysqlnd php-gd php-fpm
yum instalou dependências como php-commom, php-pdo, etc.
Eu verifiquei os processos em execução no meu servidor usando o virtualmin.
imediatamente após a reinicialização do php-fpm, cada processo do php-fpm: pool www está usando em torno de 400MB de memória.
Existem mais de 20 extensões no diretório etc / php.d.
Eu comentei a maioria das extensões no diretório etc / php.d.
depois de reiniciar o php-fpm e o nginx,
Eu verifiquei as extensões instaladas usando
<?php
print_r(get_loaded_extensions());
?>
Este é o resultado:
[0] => Core
[1] => date
[2] => ereg
[3] => libxml
[4] => openssl
[5] => pcre
[6] => zlib
[7] => filter
[8] => hash
[9] => Reflection
[10] => SPL
[11] => session
[12] => standard
[13] => cgi-fcgi
[14] => curl
[15] => ftp
[16] => gd
[17] => mysqlnd
[18] => PDO
[19] => mysql
[20] => pdo_mysql
[21] => json
[22] => mhash
agora imediatamente após a reinicialização do php-fpm, o processo de cada php-fpm: pool www está usando em torno de 250MB de memória.
