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
worker_processes 8;
隐藏 Nginx Server Tokensserver_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在Nginx配置文件的http/server/location部分设置。
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. "n">php$ "n">uri? "err">$args;
}
location "o">~* "p">.php {
fastcgi_pass "mf">127.0.0.1:;
fastcgi_index "n">index. "n">php;
include "n">fastcgi_params;
fastcgi_split_path_info "o">^(. "o">+ "p">.php "p">)(/? "p">.* "p">)$;
fastcgi_param "n">PATH_INFO $ "n">fastcgi_path_info;
fastcgi_param "n">SCRIPT_FILENAME $ "n">document_root$ "n">fastcgi_script_name;
}
禁止访问隐藏文件
location "o">~ / "err">. {
access_log "n">off;
log_not_found "n">off;
deny "n">all;
}
配置PHP-FPM PHP-FPM 基本配置
emergency_restart_threshold
emergency_restart_interval m
process_control_timeout s
配置PHP-FPM Pool 进程
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。
假设你打算给1G内存给当前配置的PHP-FPM Pool，一般一个PHP请求占用内存10M-40M，我们按站点每个PHP请求占用内存25M，这样max_children = 1G/25M = 40.96。
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

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. "n">d/* "p">.conf
开启PHP-FPM状态信息页
php-fpm.conf配置文件要启用以下选项：
在Nginx配置的server部分增加以下配置：
location "o">~ ^/ "p">(status "p">)$ {
access_log "n">off;
include "n">fastcgi_params;
fastcgi_pass "mf">127.0.0.1:;
fastcgi_param "n">SCRIPT_FILENAME $ "n">document_root$ "n">fastcgi_script_name;
}
访问http://localhost/status 查看php-fpm状态
