20 SEPARATE MACHINES

21 FPM-1 SESSIONS WEBSERVER FPM-2 DATA FPM-N

22 upstream php-pool { server unix:/run/php-fpm/ max_cons=10; server :9000 weigth=5; server :1345 max_fails=3 fail_timeout=30s; server :9000 down; } server :9000 backup;

23 BUT SOCKETS!

24 WEBSERVER + PHP SESSIONS LOAD BALANCER WEBSERVER + PHP DATA WEBSERVER + PHP

25 FPM-1 SESSIONS WEBSERVER FPM-2 DATA FPM-N

26 FPM-1 DATA READ SLAVE SESSIONS WEBSERVER FPM-2 DATA READ SLAVE DATA FPM-N DATA READ SLAVE

27 OPCACHE

29 TUNE IT!

34 MULTIPLE POOLS

35 WORKER WORKER POOL X WORKER :9000 FPM MASTER PROCESS WORKER WORKER WORKER WORKER POOL Y WORKER WORKER

36 WORKER WORKER POOL X WORKER :9001 FPM MASTER PROCESS WORKER WORKER WORKER WORKER POOL Y WORKER WORKER

37 OPTIMIZED FOR USE CASES

38 [www] user = web-user group = web-user listen = :9000 listen.owner = web-user listen.group = web-user listen.mode = 0666 slowlog = /var/log/php7.1-fpm/slow.log request_slowlog_timeout = 1s pm = static pm.max_children = 200 pm.max_requests = pm.status_path = /status php_admin_value[memory_limit] = 32M

41 SEPARATE POOL PER APPLICATION VERSION

42 REMOVE UNUSED EXTENSIONS

43 SEPARATE FPM MASTER PROCESSES

44 SYSTEMD EXAMPLE

45 [Unit] Description=The PHP FastCGI Process Manager After=syslog.target network.target [Service] Type=notify ExecStart=/usr/sbin/php-fpm -c /etc/php-fpm.d/ipc/php.ini -y /etc/php-fpm.d/ipc/fpm.conf --nodaemonize ExecReload=/bin/kill -USR2 $MAINPID PrivateTmp=true RuntimeDirectory=php-fpm2 RuntimeDirectoryMode=0755 [Install] WantedBy=multi-user.target

46 REDUCE I/O

47 LOG FILES

48 AVOID REDUNDANT LOGGING

49 SESSION HANDLING

51 /etc/php/php.ini session_probability = 0

53 <?php session_start(); session_gc(); session_destroy();

54 REDIS SESSIONS

55 APPLICATION I/O

56 USE PERSISTENT CONNECTIONS

57 OFFLOAD WORK FROM FPM

58 X-ACCEL-REDIRECT

59 NGINX FILE UPLOAD EXAMPLE

60 location /upload { limit_except POST { deny all; } client_body_temp_path client_body_in_file_only /var/www/uploads; on; client_body_buffer_size 1024K; client_max_body_size 10G; fastcgi_pass include unix:/run/php-fpm/ fastcgi_params; fastcgi_pass_request_headers fastcgi_pass_request_body on; off; fastcgi_ignore_client_abort on; fastcgi_param X-FILE $request_body_file; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /var/www/php/index.php; }

61 NEXT LEVEL: TCP TUNING
