Hello. I am developing a auto-installer(written in php) to install php scripts(like wordpress, joomla etc). This auto-installer downloads package(e.g. wordpress), extracts it in web user document root(say /var/www/clients/clientX/webX/web) and installs the packge. I have added the installer at ispconfig doc_root i.e. at /usr/local/ispconfig/interface/web/. Now the issue is the installer runs as the user ispconfig and the user folder(say /var/www/clients/clientX/webX/web) owner is webX and due to this installer cannot copy or create directories at the user document_root. What I need to do to make the auto-installer run as the user webX?
