 注意：正则匹配时 ^~ /tomcat/   在地址proxy_pass http://myserver/;  一定得写/，否则一直提示404

} 
http {
     upstream testwebapi {  
        server 127.0.0.1:9001;  
        server 127.0.0.1:9002;

     server {

        server_name  _;

        client_max_body_size 20M;        
 
        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;
 
        location / {
