How to add a second site in httpd.conf - apache

Question

I'm using the following configuration of httpd.conf in my CentOs 7 Apache server to run "site1":
ServerRoot "/etc/httpd"
Listen 80
Include conf.modules.d/*.conf
User apache
Group apache
ServerAdmin root#localhost
ServerName locahost:80
<Directory />
AllowOverride none
Require all denied
</Directory>
DocumentRoot "/var/www/html/site1"
<Directory "/var/www">
AllowOverride None
# Allow open access:
Require all granted
</Directory>
<Directory "/var/www/html/site1">
Options FollowSymLinks
AllowOverride all
Order allow,deny
Allow from all
</Directory>
<IfModule dir_module>
DirectoryIndex index.html
</IfModule>
<Files ".ht*">
Require all denied
</Files>
ErrorLog "logs/error_log"
LogLevel warn
<IfModule log_config_module>
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined
LogFormat "%h %l %u %t \"%r\" %>s %b" common
<IfModule logio_module>
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %I %O" combinedio
</IfModule>

</IfModule>
<IfModule alias_module>
ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"
</IfModule>
<Directory "/var/www/cgi-bin">

</Directory>
<IfModule mime_module>
TypesConfig /etc/mime.types
AddType application/x-compress .Z
AddType application/x-gzip .gz .tgz

AddOutputFilter INCLUDES .shtml
</IfModule>
AddDefaultCharset UTF-8
<IfModule mime_magic_module>
MIMEMagicFile conf/magic
</IfModule>
EnableSendfile on
IncludeOptional conf.d/*.conf
When I access "http://localhost", site1 and its subpages/subfolders work correctly.
I want now to be able to display a second website: when accessing "http://localhost/site2", I want to display the content of a file "test.html" saved under "/test"; how should I edit the httpd.conf to make it work?

Answer 1

that's not a different site, it is a different directory. A different site would involve a different hostname.
Since you already have DocumentRoot "/var/www/html/site1 and you don't seem to want to create a new virtualhost you can point to a new/different directory with Alias
Also you just want site2 to load test.html under /test/ If I understood correctly when visited, just add the proper DirectoryIndex directive to it.
Here it is:
Alias /site2 /var/www/html/site2
<Directory /var/www/html/site2>
DirectoryIndex /test/test.html
</Directory>
For this to work you need these two modules:
mod_alias
mod_dir (but you may already have this one as you are already using DirectoryIndex directive)
You could also mkdir site2 under site1 but, this may look cleaner.
