  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 127.0.0.1:8400 weight=1;

  server 127.0.0.1:8401 weight=1;

  # server 127.0.0.1:8402 weight=1;

  }

  server {

  listen 80;

  server_name 192.168.50.30;

  location / {

  proxy_pass http://127.0.0.1:9000$request_uri;

  proxy_set_header Host $host;

  proxy_set_header X-Real-IP $remote_addr;

  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

  }

  }

  server {

  listen 443;

  server_name example.;

  ssl on;

  ssl_certificate ssl.crt;

  # 与apache类似,nginx也不使用有密码的ssl key

  ssl_certificate_key ssl-nokey.key;

  ssl_session_timeout 5m;

  ssl_protocols SSLv2 SSLv3 TLSv1;

  #ssl_ciphers HIGH:!aNULL:!MD5

  ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;

  ssl_prefer_server_ciphers on;

  #双向认证

  #ssl_client_certificate ca.crt;

  #双向认证

  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;

  }

  }

  }
