需求一：
1.浏览器请求Nginx（http://111.229.248.243:9003）;
2.Nginx将请求转发至目标服务器（tomcat页面）；

需求二：
需求一基础上新增两个目标服务：
1.当访问：http://111.229.248.243:9003/abc 的时候，实际访问目标是：172.0.0.1:8080
2.当访问：http://111.229.248.243:9003/def 的时候，实际访问目标是：172.0.0.1:8081

需求一配置实现：
1.部署tomcat，保持默认监听8080端口；
2.修改nginx配置；

3.重新加载配置
./nginx -s reload
4.测试访问：http://111.229.248.243:9003，返回tomcat页面

需求二实现：
1.部署tomcat，保持默认监听8081端口；
2.修改nginx配置；

多location的使用：
对应location语法：
location [=||*|^~] /uri/ { … }
在nginx配置⽂件中，location主要有这⼏种形式：
1）正则匹配 location ~ /lagou { }
2）不区分⼤⼩写的正则匹配 location ~* /lagou { }
3）匹配路径的前缀 location ^~ /lagou { }
4）精确匹配 location = /lagou { }
5）普通路径前缀匹配 location /lagou { }
优先级:4 > 3 > 2 > 1 > 5
3.重新加载配置
./nginx -s reload
nginx配置文件如下：

#user nobody;
#worker进程数量，通常设置为和cpu数量相等
worker_processes 1;
#全局错误日志及pid文件位置

#error_log logs/error.log info;
#pid logs/nginx.pid;
