本文介绍Nginx的基本配置及如何实现简单的负载均衡。通过配置upstream模块，可以将请求分发到多个后端服务器，提高网站的可用性和响应速度。文章还涉及错误日志记录、连接数设置等内容。

#user nobody;
worker_processes 1;#设置nginx服务的worker子进程，比如设为2：

error_log logs/error.log; #去掉前面的#，记录nginx错误日志，方便检查bug：
error_log logs/error.log notice;
error_log logs/error.log info;

#pid logs/nginx.pid; #nginx的pid位置

events {
worker_connections 1024; #每个进程允许的最多连接数，
}

#这里很关键，很多小伙伴问我 “负载均衡乍配置，为啥我配置的不能访问呢“，这里的upstream就是配置负载均衡的，当然得两台以上才叫负载，我这里的ip69和68都是
#用的apache, 也许你们的是tomcat, 没关系，按这样配置一样可以，
upstream proxy_test {
server 127.0.0.1:8080 weight=1; #如果你要测试，把这里换成你自己要代理后端的ip
server 127.0.0.1:8081 weight=1;
ip_hash; #当负载两台以上用ip_hash解决session的问题，一台就别hash了。
}
#这是server段的配置

listen 80;
server_name localhost;#要访问的域名，我这里用的测试域名，如果有多个，用逗号分开
