linux multi instances

Hi Radek,

Have you installed multiple instances in separate folders yet? We often give them simple names here, like ss1, ss2, ss3, etc. Each folder is a separate installation, so each has its own screen-scraper.jar, resource and lib folders, executable files, etc.

Once you have installed screen-scraper multiple times, you'll have to change the ports, like you mentioned. Here are the common ports that you'll want to make unique for each instance of screen-scraper:

Name		Default Port
DatabasePort		9005
SOAPPort		8779
ServerPort		8778
ProxyPort		8777
WebServerShutdownPort		8555

There's a properties file where you can change these values. If screen-scraper is installed in the folder ss1, then the path to the properties file would be:

Open this file with a text editor and edit the lines that have the names listed above. It's best to have a convention of some kind. Our favorite convention is adding a number to the front of the default port, like ServerPorts would be 18778, 28778 (though this doesn't work for too many installations).

To run the server from the command line, go to the root screen-scraper folder (ss1, for example) and type the command:

To stop the server or simply check whether or not it's running, you can type either of these commands:

If you have scraping sessions to import, you can place copies of them in the import folder and restart screen-scraper(./server stop and then ./server start). The scraping sessions will be imported when screen-scraper starts. (The session will be removed from the import folder, too, so it doesn't get re-imported every time screen-scraper starts)
