nginx负载均衡配置-windows（nginx负载均衡配置,当前机器宕机）

nginx负载均衡配置-windows

虽然说windows上的nginx在官方文档中提到"仅作为测试"之用，但对于小规模并发场景还是比apache有不小的优势。所以，本文也将其作为windows服务器上负载均衡的主要工具进行说明。

配置实例

#user nobody;

#指定nginx进程数，通常与CPU数相一致。特别是在windows平台中，这一数值一般只能设置为1.

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 {

# windows平台基本只能设置为1024

worker_connections 1024;

}

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"';

#access_log logs/access.log main;

# 如果应用未使用文件传递，则可关闭此项。

sendfile off;

#tcp_nopush on;

keepalive_timeout 15;

#gzip on;

# HTTPS server

upstream cas_servers {

#使用C类网络中的IP HASH方式进行负载分流

ip_hash;

# server 127.0.0.1:8402 weight=1;

}

}

}

ssl_verify_client off;

location / {

proxy_pass http://cas_servers$request_uri;

# 将client端传递过来的HTTP Host转发给给后端 Web AppServer

proxy_set_header Host $host;

# 传递client端的真实IP,但如果后端 Web AppServer 没有对此进行专门处理，也没啥作用

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

# 如果使用了 SSL,则将HTTP SSL_CERT 参数转发给后端 Web AppServer

proxy_set_header SSL_CERT $ssl_client_cert;

}

}
