近期要设置一个前端页面，意图访问www.abc.com,就会显示该前端页面,前端页面的入口文件为index.html:
我原先的设置是所有的访问都会默认走 rewrite ^(.*)$ /app.php last;这条规则，
现在为了达成目的，理论上在添加一个location = / 就可以了，但是实际上是不行的，实际上还要增加location = /index.html，请问老师这是为啥？谢谢

server {
listen 80;
server_name www.abc.com;

#location = /index.html {
#   root          /server/wwwroot/distribution/h5;
#}
location = / {
	root           /server/wwwroot/distribution/h5;
	index          index.html;
}
location / {
rewrite ^(.*)$ /app.php last;
}

location = /app.php {
     root           /server/wwwroot/distribution/public/;             
     fastcgi_pass   unix:/tmp/distribution.sock;
     fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
     include        fastcgi_params;
}

}
