nginx 配置

官网：http://nginx.org/en/

#全局设置
main 
# 运行用户
user www-data;    
# 启动进程,通常设置成和cpu的数量相等
worker_processes  1;

# 全局错误日志及PID文件
error_log  /var/log/nginx/error.log;
pid        /var/run/nginx.pid;

# 工作模式及连接数上限
events {
    use epoll; #epoll是多路复用IO(I/O Multiplexing)中的一种方式,但是仅用于linux2.6以上内核,可以大大提高nginx的性能
    worker_connections 1024; #单个后台worker process进程的最大并发链接数
    # multi_accept on; 
}

#设定http服务器，利用它的反向代理功能提供负载均衡支持
http {
    #设定mime类型,类型由mime.type文件定义
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;
    #设定日志格式
    access_log    /var/log/nginx/access.log;

    #sendfile 指令指定 nginx 是否调用 sendfile 函数（zero copy 方式）来输出文件，对于普通应用，
    #必须设为 on,如果用来进行下载等应用磁盘IO重负载应用，可设置为 off，以平衡磁盘与网络I/O处理速度，降低系统的uptime.
    sendfile        on;
    #将tcp_nopush和tcp_nodelay两个指令设置为on用于防止网络阻塞
    tcp_nopush      on;
    tcp_nodelay     on;
    #连接超时时间
    keepalive_timeout  65;

    #开启gzip压缩
    gzip  on;
    gzip_disable "MSIE [1-6].(?!.*SV1)";

    #设定请求缓冲
