Here is ngnix reverse proxy, ngnix forwards dynamic requests to tomcat

 server
    {
  listen 80default;
  server_name 127.0.0.1:8080;
  charset utf-8;
  access_log logs/host.access.log;
        
  location /{
   proxy_pass http://127.0.0.1:8080;}}
 include /usr/local/nginx/conf/host/*.conf;
}

# Check if there are errors in the configuration file
[ root@VM_177_101_centos conf]# /usr/local/nginx/sbin/nginx  -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

# Start nginx
service nginx start

At this point, nginx has been installed successfully, and then tomcat is enabled, and the tomcat welcome page can be accessed through ip.
