Gitlab Falied to update IP, and where is the php.ini?

Hello, I have just installed Gitlab Stack 5.0, and add the redmine module in it, Install Owncloud and SugarCRM manualy from source, I need to customize the php.ini on Gitlab Stack to increase upload size on the owncloud application, I have search using find command but I do not find it, Can someone help me?

And the other probllem is I cant change the ip hostname, using ipupdate command,

root@ubuntu:/opt/gitlab-5.0-0/apps/gitlab#./updateip  --machine_hostname tedi.com
There has been an error.
Error reading INI file /opt/bitnami/properties.ini

Than, I try to change the /opt/gitlab-5.0-0/apps/gitlab/htdocs/config/gitlab.yml, And change

From

## GitLab settings
  gitlab:
    ## Web server settings
    host: 192.168.2.12
    port: 80
    https: false

to

## GitLab settings
  gitlab:
    ## Web server settings
    host: tedi.com
    port: 80
    https: false

Than restart the application, but when I clone the repository after I change the host from gitlab.yml, My repository is error and can not be clone.

Is the any clue?
