Change
KeepAlive onMaxKeepAliveRequests 100
Change
MaxKeepAliveRequests 500 // you can increase the efficiency;
StartServers 8

ServerLimit 256
MaxClients 256
MaxRequestsPerChild 4000
StartServers 4
MaxClients 300

Is the website IP address illegally directed to another domain name? How does Apache disable malicious domain names from directing to your server IP address:

Solution 1: Create a VM: <VirtualHost *: 80>
ServerName 171.111.158.91 // change to the IP address of your server;
<Location/>
Order Allow, Deny
Deny from all
</Location>
</VirtualHost> solution 2: create the first VM (no defined domain name is used by default to access the content of the first VM): <VirtualHost *: 80>
DirectoryIndex index.html index.htm index. php
DocumentRoot/var/www/html/test // define an empty directory, or place a website page to display the information you need to specify; <Directory/var/www/html/test>
ServerName 171.111.158.91 // change to the IP address of your server;
// The Directory is the same as above;
Order allow, deny
Allow from all
</Directory>
</VirtualHost> ......
