本文主要是介绍nginx 配置 upstream backup 报错，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
启动 nginx 的时候 报错 错误信息如下:
nginx: [emerg] balancing method does not support parameter "backup" in /usr/local/nginx/conf/nginx.conf:40
原因是backup 和 ip_hash 无法同时使用（Ip_hash balancer does not support backup servers and weight）。
#user nobody;

#error_log logs/error.log notice;
#error_log logs/error.log info;#pid logs/nginx.pid;events {worker_connections 1024;
