nginx负载均衡设置

# 分布式服务器 192.168.0.1和192。168.0.2和192.168.0.3均设置一遍
server {
	listen 8090;
	index index.html index.htm index.php default.html default.htm default.php;
	root  /home/xxx_staging_deploy/current/wap;
	location /{
		
	}
	include none.conf;
	error_page   404   /404.php;
	location ~ [^/]\.php(/|$) {
		try_files $uri =404;
		fastcgi_pass  unix:/tmp/php72-cgi.sock;
		fastcgi_index index.php;
		include fastcgi.conf;
	}
}

先插入代码段，然后解释下。ip都让我换成19.168.0.x了。负载转发主要做在192.168.0.1和192.168.0.2和192.168.0.3，均都在8090端口。因为地址为https访问，所以特别注意proxy_set_header X-Forwarded-Proto https; 。配置中的192.168.0.1为负载服务器，本身也为转发服务器。192.168.0.2和192.168.0.3的nginx配置雷同。
