nginx配置集群 -websocket

前幾天做一個nginx的反向代理，來代理websocket。

因為上線時間的問題，所以是單節點運行。現在準備做集群優化，然後上容器環境。

這樣就需要配置nginx的負載均衡。不廢話了，下面是配置文件。當然配置後需要驗證，驗證的時候會出現很多奇怪的問題。這裡就不進行描述了。

#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;

    keepalive_timeout  65;

    map $http_upgrade $connection_upgrade {
        default upgrade;
        ''      close;
    }
   
	
    upstream testCluserN {
    	# 這裡如果是本機要使用127.0.0.1  測試的時候如果使用ip websocket建立鏈接的時候會報錯
    	# max_fails=10 fail_timeout=10s 測試的時候也必須要加
    	# 輪詢
