使用 Nginx 提升网站访问速度

http://www.ibm.com/developerworks/cn/web/wa-lo-nginx/

配置Nginx

先来看一个实际的配置文件：

usernobody;#工作进程的属主

worker_processes4;#工作进程数，一般与CPU核数等同

#error_loglogs/error.log;

#error_loglogs/error.lognotice;

#error_loglogs/error.loginfo;

#pidlogs/nginx.pid;

events{

useepoll;#Linux下性能最好的event模式

worker_connections2048;#每个工作进程允许最大的同时连接数

}

http{

includemime.types;

default_typeapplication/octet-stream;

#log_formatmain'$remote_addr-$remote_user[$time_local]$request'

#'"$status"$body_bytes_sent"$http_referer"'

#'"$http_user_agent""$http_x_forwarded_for"';

#access_logoff;

access_loglogs/access.log;#日志文件名

sendfileon;

#tcp_nopushon;

tcp_nodelayon;

keepalive_timeout65;

includegzip.conf;

#集群中的所有后台服务器的配置信息
