I tried, my server is running normally, and after the jump,

However, when I close the server and directly open html and then jump to the server, it may still be a problem with your server.
Try to use 127.0.0.1/home.html or localhost/home.html for access. If it cannot be accessed, it is really the reason for your server.

Try restarting the server. If apache is installed in linux a few days ago, the website directory is normal and associated with php is normal. The problem is that the server is installed first. But wamp is integrated. Try it, maybe not?

The problem has been solved. the main problem is that port 80 is occupied by Microsoft IIS 10.0. I also found this problem a few days ago. Then I went to Apache> Use a port other than 80 and changed it to 8080. The icon turned green but it still failed to run.
Today, I found the method to change Apache> httpd. conf (I don't know what the difference is). The specific method is as follows:

1. Icon> Apache> httpd. conf.Listen 0.0.0.0:80AndListen [::0]:80ChangeListen 0.0.0.0:8080AndListen [::0]:8080, Save. in fact, restart WampServer here and you will be able to use the address for normal access. but click the icon> localhost, but the page cannot be reached. so we need to take the second step to change the address pointed to by this button.

2. Go to the WampServer installation directory and open wanpmanager. tpl.localhostChangelocalhost:8080. Solve the problem.

In addition, the method for accessing files in www cannot be passed "file :///... /wamp64/www/xxx.html ", but" http: // localhost: 8080/xxx.html ".
