dns - is there any limit for using server_name domains in nginx? -

i want point multiple domains nginx instance. use server_name pointing them.

server_name mydomain.com www.mydomain.com test.mydomain.com test1.mydomain.com; 

is above given best practice or there's other safe/stable method doing same?

you define quite lot server_names (even few thousand won't slow down). however, if want config remain readable, should either:

• use regex match host string server block
• use default server match not explicitly defined in other server
• blocks use wildcard server_names

keep in mind using exact names faster using wildcards or regex.

in case want stick using long list of server names, should include additional config file:

server {     include /somewhere/server_names;     ... } 

add. file:

server_name     mydomain.com      www.mydomain.com     ... 

see nginx docs on server_name more info...
