nginx 配置 upstream backup 报错

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;
worker_processes  1;#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;#pid        logs/nginx.pid;events {worker_connections  1024;
}http {include       mime.types;default_type  application/octet-stream;sendfile        on;upstream backend {ip_hash;server 127.0.0.1:8010;server 127.0.0.1:8080 max_fail=3 weight=2;server www.baidu.com backup;}	server {listen       80;server_name  localhost;#charset koi8-r;#access_log  logs/host.access.log  main;location / {root   /usr/www/tyy/;index  tyy.html;}location /static {alias   /usr/www/static/;}location =/baidu.html {proxy_pass http://www.baidu.com;}location /tyy/ {proxy_pass http://127.0.0.1:8010;}#error_page  404              /404.html;# redirect server error pages to the static page /50x.html#error_page   500 502 503 504  /50x.html;location = /50x.html {root   html;}}
}
