配置nginx支持php
#user nobody;
user www www;
worker_processes auto;
ginx要开启的进程数 一般等于cpu的总核数,没必要开那么多,1个nginx内存消耗10兆左右
#worker_processes 4;
为每个进程分配cpu,上例中将4 个进程分配到4个cpu,当然可以写多个,或者将一 个进程分配到多个cpu
#worker_cpu_affinity 00000001 00000010 00000100 00001000;
# 开启nginx错误日志
error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
pid logs/nginx.pid;
每个nginx进程打开文件描述符最大数目 配置要和系统的单进程打开文件数一
致,linux 2.6内核下开启文件打开数为65535,worker_rlimit_nofile就相应,应该填写65535
nginx调度时分配请求到进程并不是那么的均衡,假如超过会返回502错误。我这里写的大一点
worker_rlimit_nofile 819200;
events {
# 设置用于复用客户端线程的轮询方法。如果你使用Linux 2.6+,你应该使用epoll。
# 如果你使用*BSD,你应该使用kqueue。
# 值得注意的是如果你不知道Nginx该使用哪种轮询方法的话,它会选择一个最适合你操作系统的
use epoll;
`# 每个工作进程允许最大的同时连接数(Maxclient = work_processes * worker_connections)
# 默认1024
worker_connections 40960;
`
}
http {
# 打开accunting日志分析
http_accounting on;
http_accounting_name "JGsrv";
http_accounting_time 30;
`# 文件头信息
include mime.types;
默认类型
default_type application/octet-stream;
限制连接模块
limit_req_zone $binary_remote_addr zone=allips:10m rate=20r/s;
保存服务器名字的hash表是由指令server_names_hash_max_size 和server_names_hash_bucket_size所控制的。
参数hash bucket size总是等于hash表的大小,并且是一路处理器缓存大小的倍数
server_names_hash_bucket_size 128;
客户端请求头部的缓冲区大小,这个可以根据你的系统分页大小来设置,
一般一个请求的头部大小不会超过1k,不过由于一般系统分页都要大于1k,
所以这里设置为分页大小。分页大小可以用命令getconf PAGESIZE取得。
client_header_buffer_size 32k;
客户请求头缓冲大小
nginx默认会用client_header_buffer_size这个buffer来读取header值,如果
large_client_header_buffers 4 32k;
设定通过nginx上传文件的大小
client_max_body_size 64m;
磁盘和TCP socket之间互相拷贝数据(或任意两个文件描述符)。
Pre-sendfile是传送数据之前在用户空间申请数据缓冲区
sendfile on;
告诉nginx在一个数据包里发送所有头文件,而不一个接一个的发送
tcp_nopush on;
告诉nginx不要缓存数据,而是一段一段的发送,
当需要及时发送数据时,就应该给应用设置这个属性,这样发送一小块数据信息时就不能立即得到返回值。
tcp_nodelay on;
并不会让nginx执行的速度更快,但它可以关闭在错误页面中的nginx版本数字,这样对于安全性是有好处的
server_tokens off;
keepalive超时时间
keepalive_timeout 65;
优化fastcgi
fastcgi_connect_timeout 120;
fastcgi_send_timeout 120;
fastcgi_read_timeout 120;
fastcgi_buffer_size 64k;
fastcgi_buffers 4 64k;
fastcgi_busy_buffers_size 128k;
fastcgi_temp_file_write_size 128k;
fastcgi_intercept_errors on;
开启gzip压缩
gzip on;
默认值: 0 ,不管页面多大都压缩
gzip_min_length 1k;
设置系统获取几个单位的缓存用于存储gzip的压缩结果数据流
例如 4 4k 代表以4k为单位,按照原始数据大小以4k为单位的4倍申请内存
gzip_buffers 4 16k;
gzip_http_version 1.0;
gzip_comp_level 2;
gzip_types text/plain application/x-javascript text/css application/xml;
gzip_vary on;
这个将为打开文件指定缓存,默认是没有启用的,max 指定缓存数量,建议和打开文件数一致,
inactive 是指经过多长时间文件没被请求后删除缓存
open_file_cache max=409600 inactive=10s;
# 这个是指多长时间检查一次缓存的有效信息
open_file_cache_valid 5s;
# open_file_cache 指令中的inactive 参数时间内文件的最少使用次数,
如果超过这个数字,文件描述符一直是在缓存中打开的,
如上例,如果有一个文件在inactive 时间内一次没被使用,它将被移除
open_file_cache_min_uses 2;
log_format access_logs '$upstream_response_time $request_time $status $body_bytes_sent $remote_addr $time_local "$http_user_agent" "$request" "$http_referer" "$http_x_forwarded_for"';
Nginx负载均衡配置
upstream phpServer{
# 服务器内网地址,weight:权重,负载越大 max_fails:允许请求失败的次数 fail_timeout:次失败后,暂停的时间
server 172.20.17.210:9000 weight=1 max_fails=2 fail_timeout=3;
server 172.20.17.211:9000 weight=1 max_fails=2 fail_timeout=3;
}
配置虚拟主机,过个server就复制多个
include vhost/*.conf;
`
}
Vhost目录下的虚拟机配置文件
server {
listen 80;
server_name jt018.com www.jt018.com;
root /data/www/jt018.com/;
`#access_log logs/host.access.log main;
配置域名重定向
#if ($host != 'www.jt018.com' ) {
rewrite ^/(.*)$ http://www.yphp.cn/$1 permanent;
#}
location / {
# 配置rewrite
if (!-e $request_filename) {
rewrite ^(.*)$ /index.php?$1 last;
break;
}
include /usr/local/nginx/html/yphp/.htaccess;
rewrite ^/(.+)/(.+)[/]?$ /index.php?m=$1&a=$2 last;
配置默认访问文件
index index.php index.html index.htm;
}
静态文件缓存30天
location ~ .*.(gif|jpg|jpeg|png|bmp|swf|ico)$
{
expires 30d;
# access_log off;
}
js,css文件缓存15个小时
location ~ .*.(js|css)?$
{
expires 15d;
# access_log off;
}
#error_page 404 /404.html;
redirect server error pages to the static page /50x.html
error_page 500 502 503 504 /50x.html;
#location = /50x.html {
root html;
#}
pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
location ~ .php$ {
#fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_intercept_errors on;
fastcgi_pass phpServer; # 修改为upstream定义的名称
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
