Deploy several MISP instance in same VM

[esteban-armas]

Dear all, I would like to change the default port of MISP instead of 80 or 443 to use another one (e.g. 8081, 8443). This because within the same VM I will deploy several MISP instances and through an Nginx, I will redirect the access. If someone can help me with how to modify it I would appreciate it.
Currently I have applied:

<VirtualHost *:8081>
ServerAdmin admin@localhost
ServerName localhost
DocumentRoot /var/www/MISP/app/webroot
<Directory /var/www/MISP/app/webroot>
Options -Indexes
AllowOverride all

LogLevel warn
ErrorLog /var/log/apache2/misp_error.log
CustomLog /var/log/apache2/misp_access.log combined
ServerSignature Off

But it doesn't work by changing the port there.

Regards
