WdcpPort instructions
The default port 8080 is used in the wdcp background (wdcp2.2 can be directly modified in the background)
In lamp Environment
Httpd uses port 80.
In the lnmp Environment
Nginx uses port 80
In the lnamp environment (that is, nginx front-end, processing of static files, images, etc., apache background, processing of php dynamics)
Apache uses port 88 (unchangeable)
Nginxd uses port 80 (which can be modified in the background)
In the lnamp environment, there are multiple ports. I hope no one will ask why apache uses port 88.
The default ftp port is 21.
It can also be modified directly in the background from wdcp2.2.
Wdcp background. The default port is 8080. It can be changed to the background of wdcp on another port. It can restrict access to IP addresses or domain names.
After these restrictions and settings are made, it is relatively secure and generally no one knows how to access your background.
However, in some cases, some of the search engines also include the background address, so the background address is exposed.
