Is one site integrated with deployment solutions for multiple mature products?

I am preparing to create a website recently. This site will be used in malls, forums, and CMS, but similar products have mature products. These need to be integrated to form a site. Suppose they are all php products. The server uses nginx. Domain Name Pointing to: varwww without testing, I thought about... recently preparing to do a site. This site will be used in malls, forums, CMS, etc.
However, similar products have mature products. These need to be integrated to form a site.

Suppose they are all php products. The server uses nginx.
Domain Name Pointing to:/var/www
I thought about two solutions without testing.
Solution 1:
Under the www directory shop is the mall system, under bbs is discuz, and under the root directory is cms
Url rewriter is used for every project. In the past, when there was only one cms, I could
The request is sent to/var/www/index. php, but it seems a bit complicated now.
Domain name/bbs/* should all point to index. php under bbs

Solution 2:
I know that there is a second-level domain name, can it be deployed like this?
/Var/www put cms
/Var/bbs Project
/Var/shop mall project

Then the primary domain name points to www
The second-level domain name points to bbs and shop.

I don't know if any of you have made these things. Could you give me some advice?

My deployment solution isPrimary Domain Name + secondary Domain Name

/home/www/cmsPut cms
/home/www/bbsBbs Project
/Home/www/shop mall project

Then the primary domain name points/home/www/cms
Second-level domain name pointing/home/www/bbsAnd/home/www/shop.

Put multiple configurations in/usr/local/nginx/conf. d/, and deploy the power-on-line system using a deployment tool.
