nginx统一入口 多服务出口

nginx配置多ip和端口统一调用入口
log_format中$upstream_addr 标识打印转发的url地址
配置upstream和location
 
http {
include       mime.types;
default_type  application/octet-stream;
 
log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                  '$status $body_bytes_sent "$http_referer" '
                 '"$http_user_agent" "$http_x_forwarded_for" "$upstream_addr" ';
 
access_log  logs/access.log main;
 
sendfile        on;
#tcp_nopush     on;
 
#keepalive_timeout  0;
keepalive_timeout  65;
 
#gzip  on;
