Nginx反向代理以及配置优化

下面配置包含了，nginx配置的一个比较全面的反向代理的例子：

user www www
worker_processes  8;



events {
    use epoll;
    worker_connections  10240;
}

pid       /opt/work/log/nginx.pid;
error_log /dev/null error;

http {

    include /opt/nginx/conf/mime.types;
    default_type     text/html;

     log_format  pv  '[$time_local]|$remote_addr|$cookie_SUV|$args|$http_referer|$http_user_agent';

     log_format   main '$request_time $remote_addr $cookie_SUV [$time_local]  $status '  '"$request" $body_bytes_sent "$http_referer" '  '"$http_user_agent" "$http_x_forwarded_for"'  '"$cookie_Fr"';
    
     log_format  pbmain    '$remote_addr - $remote_user [$time_local] "$request" '
                                '$status $body_bytes_sent "$http_user_agent"';
     access_log off;

     sendfile    on;
