## 问题分析 ##

*  根据提供的访问日志和nginx.conf配置文件分析，是循环重定向的问题。
 *  配置中，location / 块使用了 `try_files $uri $uri/ /index.html;` 会导致导致在尝试访问根目录时发生重定向循环。
 *  修改：添加一个新的`location=/index`块，直接提供 /index.html 而不进行重定向。

server {
        
        listen 80;
        server_name my_server_name;
    
        location / {
        
            root /usr/local/xxx_vue;
            index index.html index.htm;
            try_files $uri $uri/ /index.html;
        }
    
        location = /index.html {
        
            root /usr/local/xxx_vue;
        }
    
        location ^~ /api/ {
        
            proxy_pass http://xxx.xxx.xxx.xxx:8080/;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
    }

*  使用以下命令重新加载Nginx,即可生效
    
        sudo nginx -s reload
