nginx는 stable 라인과, mainline 최신버전이 있는데 안정성을 위해 stable 이 기본으로 되어있습니다.
혹여 모르니 nginx-stable를 선택합시다.
yum-config-manager --enable nginx-stable
yum-config-manager --disable nginx-mainline

yum clean all
yum update -y 
yum install -y nginx

PHP-FPM 설정파일 확인 주요 설정

 

vi /etc/php-fpm.conf 

 

pid = /run/php-fpm/php-fpm.pid

error_log = /var/log/php-fpm/error.log

syslog.facility = daemon

syslog.ident = php-fpm

log_level = warning

log_limit = 4096

emergency_restart_threshold = 10

emergency_restart_interval = 10

process_control_timeout = 10

systemd_interval = 10

 

PHP-FPM www.conf 설정파일 주요 설정

 

vi /etc/php-fpm.d/www.conf

user = nginx       -> apache 데몬이나 nginx 데몬에 설정된 유저를 같이 적는게 맞다. 

group = nginx     -> apache 데몬이나 nginx 데몬에 설정된 그룹를 같이 적는게 맞다.  (nginx는 없다.)

 

PHP-FPM를 어떻게 운영하는가에 따라 TCP/IP or UDS (Unix Domain Socket)

listen = 127.0.0.1:9000 

또는

listen = /var/run/php-fpm/php-fpm.sock

listen.owner = nginx
listen.group = nginx
listen.mode = 0660

process.dumpable = yes

listen.allowed_clients = 127.0.0.1

 

pm = dynamic

 

공식

min_spare_servers + (max_spare_servers - min_spare_servers) / 2

 

pm.max_children = CPU 코어(쓰레드) 수 × 4, RAM 용량(GB)의 8배 (DB도 돌린다면 4~6배) 중 적은 쪽이 적정값입니다. 
또는 pm.max_children은 (동접수 ÷ 100)

pm.start_servers = pm.max_children의 절반 정도
pm.min_spare_servers = pm.start_servers와 같은 값
pm.max_spare_servers = pm.max_children과 같은 값

 

8코어 16쓰레드 기준

pm.max_children = 64

pm.start_servers = 32

pm.min_spare_servers = 32

pm.max_spare_servers = 64

;pm.process_idle_timeout = 10s; -> pm = ondemand일때만 사용합니다.

pm.max_requests = 500

 

access.log = /var/log/php-fpm/php-access.log

slowlog = /var/log/php-fpm/www-slow.log
