configure nginx for multiple subdomains

Question

Hello all,im sure ill find some helpful buddies here. How can i maintain multiple subdomains in nginx with same configuration. in dept, we want to host a SAAS based app where client will have their own site hosted on our subdomains. eg. site.mydomain.com , site2.mydomain.com etc. dose it require individual server block for each subdomain? or i can point all in one server block? i must add the configuration for nginx will be same for all. also could somebody point me to any script that automate this process? i really appreciate you all for your help.

Hi,

It mostly depend on you app. If every user have their own document root you should go with individual server block for each subdomain. Even if it’s not the case, it is recommended.

How to setup Nginx Server Blocks will explain you how to make it.

In addition to that, you could utilize Nginx snippets. It allows you to store configuration in one file and use it in multiple blocks.

Snippets are stored in /etc/nginx/snippets and usually have extension .conf. There you can write any configuration that you want to use under server block.

When you want to use it in block, simple include snippets/example.conf will use it in block.

Example

/etc/nginx/snippets/example.conf

root /var/www/html

/etc/nginx/sites-available/default

server {
listen...
...
include snippets/example.conf
...
}

For automatization Bash script can do job. Or something more complex like Ansible
