nginx如何做反向代理？

网络结构如上图.

可能你只有一个公网的Ip地址. 但是您的内网有个网站需要映射至外网.而又不想添加其它的非80端口.则你可以直接使用nginx来做反向代理即可.

首先,配置nginx.conf文件.

http {     include                 mime.types;     default_type            application/octet-stream;     client_max_body_size    8m;    ################################################################################     include /usr/local/u-mail/config/nginx/reverse-proxy.conf;    ################################################################################     #log_format             main  '$remote_addr - $remote_user [$time_local] "$request" '     #                             '$status $body_bytes_sent "$http_referer" '     #                             '"$http_user_agent" "$http_x_forwarded_for"';     #access_log             logs/access.log  main;     sendfile                on;    #tcp_nopush             on;     #keepalive_timeout      0;     keepalive_timeout       65;    #gzip                   on;    upload_progress         proxied 1m;    ###############################################################################    gzip             on;    #client_max_body_size    50m;    client_body_buffer_size 256k;     client_header_timeout   3m;     client_body_timeout     3m;     send_timeout            3m;     proxy_connect_timeout   300s;     proxy_read_timeout      300s;     proxy_buffer_size       64k;     proxy_buffers  4        32k;     proxy_busy_buffers_size 64k;     proxy_temp_file_write_size        64k;     proxy_ignore_client_abort        on;               ###############################################################################     include                 vhost/*.conf; }

上面的配置文件中有引用 /usr/local/u-mail/config/nginx/reverse-proxy.conf;

配置文件,这个填写可以使用相对路径,也可填写绝对路径,在此为了示范就直接填绝对路径了.

然后再来看下引用的配置文件信息.
