We have developed a web application with embedded java application web server (Jetty). We need to develop an installer and uninstaller for none gui based Linux servers (Ubuntu). We have also used H2 as an embedded database engine. Installation: The script should check if there is already a version of the application installed. If it is installed inform the user about this and give the choice to remove existing version and have a clean install or upgrade the existing version. Clean installation: Uninstall existing application and remove all file and processes. Install new version. Upgrade: Remove application without removing data files and install new application files. Update the database If there are any updates to the database schema perform an upgrade. The application should auto start with server restart. Uninstall: Confirmation dialog (Yes, No). If yes: Ask user if data files (database) should be removed as well. If yes remove application and data files if No: remove application but leave data files.

I am developing a multiplayer mobile(iOS and Android) game for a client. I want to use node.js to connect players. And I have a lot of questions I need to ask someone who is already an expert. - I have a linux server with linode.com. - my server has a REST API written in PHP, to interface with the game, storing game data in MySQL database - I need to install node.js on the server to facilitate bi-directional communication between players. - I need to send push notifications to iOS and Android devices. I need someone who will be online often, to answer my questions. The game itself is a turnbased game. when a player makes their move, it updates the database via REST PHP script. Then I need the server to let the other player know its their turn(thats all I need sockets for) If you think there is a better way to do this, please advise me.

Have a production install of SuiteCRM ver7.5.1 on a VPS linux server. Its a bit buggy and we need some help stabilizing it - reinstalling / downgrading if needed, verifying configuration details/files, performance tuning, etc. Then we want to start customizing it for enhanced sales campaigns, project management, and other functions, to be defined as a series of ongoing, modest projects.
