I got the solution,First I installed the Apache then modify the httpd.config file.I just put
ProxyRequests Off
ProxyPreserveHost On
<Proxy /geoserver>
Require all granted
</Proxy>
ProxyPass /geoserver http://localhost:8080/geoserver
ProxyPassReverse /geoserver http://localhost:8080/geoserver
ProxyPass /geoserver http://localhost:8080/geoserver
ProxyPassReverse /geoserver http://localhost:8080/geoserver
this code in httpd.config at the end of file. and then enabled this from httpd.config
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
LoadModule proxy_http_module modules/mod_proxy_http.so
Then all my html files i stored in ht-docs in Apache ,then runs all the wfs files.
