nginx做反向代理总结

首先总结代理的配置文件：

worker_processes  4;
worker_cpu_affinity 0001 0010 0100 1000;
worker_rlimit_nofile 40000;

events {
    use epoll;
    worker_connections  40000;
}


http {
    include       mime.types;
    default_type  application/octet-stream;
    charset utf-8;

    client_header_buffer_size 4k;
    open_file_cache max=8192 inactive=20s;
    open_file_cache_valid 30s;
    open_file_cache_min_uses 1;

    sendfile        on;
    tcp_nopush  on;
    tcp_nodelay on;
    keepalive_timeout  120;

    gzip on;
    gzip_proxied any;
    gzip_vary on;
    gzip_disable "MSIE [1-6]\.";
    gzip_http_version 1.1;
    gzip_min_length 10;
    gzip_comp_level 9;
    gzip_types text/plain application/x-javascript text/css  application/xml application/json application/x-httpd-php !application/x-httpd-jphp;
    
    #后端列表

                        client_body_buffer_size 128k;
                        proxy_ignore_client_abort on;

                #静态文件缓存
                location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|js|css)$
                {
                        proxy_pass http://mysvr;
                        proxy_redirect          off;
                        proxy_set_header        Host $host;
                        proxy_set_header        X-Real-IP $remote_addr;

                        client_body_buffer_size 128k;
                        proxy_connect_timeout   900;
                        proxy_send_timeout      900;
                        proxy_read_timeout      900;
                        proxy_buffer_size       4k;
                        proxy_buffers           4 32k;
                        proxy_busy_buffers_size 64k;

                        proxy_temp_file_write_size 64k;   
                        proxy_cache cache_one;   
                        proxy_cache_key $host$uri$is_args$args;   
                        expires 31d;   

                        access_log   off;
                }
        }

        server {
                listen 8080;
                location /nginx_status {
                        allow 127.0.0.1;
                        deny all;
                        stub_status on; 
                        access_log off;
                }   

        }

}

其次后端需要真实IP的处理：

server {
    set_real_ip_from         192.168.1.1;
    real_ip_header           X-Real-IP;
    real_ip_recursive        on;
}  server {
    set_real_ip_from         192.168.1.2
    real_ip_header           X-Real-IP;
    real_ip_recursive        on;
}

简单总结如上！
