使用PHP5.5.x
使用PHP5.5.x可大幅度提高Webserver负载能力，详细看这里 Nginx配置 Nginx worker_processesmax_clients = worker_processes * worker_connections worker_processes ; worker_connections ; worker_processes的数值一般设置为内核数 $ cat "o">/proc "o">/cpuinfo "o">|grep "n">processor processor "o">: processor "o">: processor "o">: processor "o">: processor "o">: processor "o">: processor "o">: processor "o">:
根据查到的内核数，这里我们配置worker_processes为8 server_tokens在Nginx配置文件的http/server/location部分设置。 Nginx Request / Upload Max Body Size (client_max_body_size)
client_max_body_size的默认值是1m，如果你的网站需要上传大于1m的文件，设置client_max_body_size为你需要的值。否则，在你上传超过client_max_body_size的文件时，Nginx会返回给你413错误，告诉你“Request Entity Too Large” 。 client_max_body_size m; client_body_buffer_size k; 缓存静态文件 location "o">~* \ "p">.(jpg "o">|jpeg "o">|gif "o">|png "o">|css "o">|js "o">|ico "o">|xml "p">)$ { access_log "n">off; log_not_found "n">off; expires d; } 启用gzip gzip_proxied "n">any; gzip_types text/ "n">css text/ "n">plain text/ "n">javascript application "o">/javascript application "o">/json application "o">/x "o">-javascript application "o">/xml application "o">/xml "o">+rss application "o">/xhtml "o">+xml application "o">/x "o">-font "o">-ttf application "o">/x "o">-font "o">-opentype application "o">/vnd "p">.ms "o">-fontobject image "o">/svg "o">+xml image "o">/x "o">-icon application "o">/rss "o">+xml application "o">/atom_xml; gzip_comp_level ; gzip_http_version "mf">1.0; gzip_vary "n">on; gzip_buffers "n">k; gzip_min_length ; 把PHP请求交给PHP-FPM location "o">/ { try_files "err">$uri "err">$uri "o">/ / "n">index.

pm.max_children是PHP-FPM Pool 最大的子进程数,他数值取决于你的服务器内存。 这样，我设置pm.max_children为40. max_requests是每个子进程重生之前处理的请求数，默认值为unlimited，设置为2000主要是为了避免内存泄露带来的问题 pm = "n">dynamic pm. "n">max_children = pm. "n">start_servers = pm. "n">min_spare_servers = pm. "n">max_spare_servers = pm. "n">max_requests = PHP-FPM Pools Configuration 建议不同站点使用不同的PHP-FPM Pool,绑定在不同的端口。这样一个站点出问题，不至于影响其他的站点。同时，如果php-fpm进程占用CPU过高，也可以很快定位有问题的站点。 下边配置了两个PHP-FPM Pool，绑定了9000和9001两个http端口 /etc/php-fpm.d/site.conf [site] listen "o">= 127.0.0.1:9000 user = "s">site group = "s">site request_slowlog_timeout "o">= 5s slowlog "o">= "s">/var/log/php-fpm/slowlog-site.log listen.allowed_clients "o">= 127.0.0.1 pm = "s">dynamic pm.max_children "o">= pm.start_servers "o">= pm.min_spare_servers "o">= pm.max_spare_servers "o">= pm.max_requests "o">= listen.backlog "o">= -1 pm.status_path "o">= /status request_terminate_timeout "o">= 120s rlimit_files "o">= rlimit_core "o">= unlimited catch_workers_output "o">= yes env[HOSTNAME] "o">= $HOSTNAME env[TMP] "o">= /tmp env[TMPDIR] "o">= /tmp env[TEMP] "o">= /tmp /etc/php-fpm.d/blog.conf [blog] listen "o">= 127.0.0.1:9001 user = "s">blog group = "s">blog request_slowlog_timeout "o">= 5s slowlog "o">= "s">/var/log/php-fpm/slowlog-blog.log listen.allowed_clients "o">= 127.0.0.1 pm = "s">dynamic pm.max_children "o">= pm.start_servers "o">= pm.min_spare_servers "o">= pm.max_spare_servers "o">= pm.max_requests "o">= listen.backlog "o">= -1 pm.status_path "o">= /status request_terminate_timeout "o">= 120s rlimit_files "o">= rlimit_core "o">= unlimited catch_workers_output "o">= yes env[HOSTNAME] "o">= $HOSTNAME env[TMP] "o">= /tmp env[TMPDIR] "o">= /tmp env[TEMP] "o">= /tmp 这段代码放在 /etc/php-fpm.conf 中，加载多个php-fpm pool include=/ "n">etc/ "n">php- "n">fpm.
