Nginx负载均衡

CentOS7
tomcat8.5
nginx-1.16.1

创建三个tomcat，分别修改端口为（8080,8081,8082）

修改配置文件： /user/local/nginx/conf/nginx.conf

upstream tomcat_server {
	server 192.168.17.129:8080;
    #weight设置权重，不设置时默认为1，如下执行次数占50%
	server 192.168.17.129:8081 weight=2;
    server 192.168.17.129:8082;
}

server {
		listen      80;
		server_name www.123.com;
		
		location / {
			proxy_pass   http://tomcat_server ;
			index        index.html index.htm;
		}
}
