有关nginx集群配置知识解读 nginx集群配置方式

nginx配置集群 -websocket

前几天做一个nginx的反向代理，来代理websocket。

因为上线时间的问题，所以是单节点运行。现在准备做集群优化，然后上容器环境。

这样就需要配置nginx的负载均衡。不废话了，下面是配置文件。当然配置后需要验证，验证的时候会出现很多奇怪的问题。这里就不进行描述了。

#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 {
    	# 这里如果是本机要使用127.0.0.1  测试的时候如果使用ip websocket建立链接的时候会报错
    	# max_fails=10 fail_timeout=10s 测试的时候也必须要加
    	# 轮询
    	server 127.0.0.1:8445 max_fails=10 fail_timeout=10s;
