Using Virtuoso Open-Source Edition on Windows Building Virtuoso on Windows requires some time and the user should be proficient with Windows software development. The build is not guaranteed to succeed out of the box. Unless you plan to actually modify the Virtuoso code, we recommend using the binary distribution. Getting Started with the VOS Binary Distribution for Windows Prerequisites Pre-built binaries of Virtuoso 6.1.4 to 7.1.0 for Windows require the Microsoft Visual C++ 2010 Redistributable Package be installed. This can be downloaded from the following locations: 32-bit Microsoft Visual C++ 2010 Redistributable Package (x86) 64-bit Microsoft Visual C++ 2010 Redistributable Package (x86_64) Pre-built binaries of Virtuoso 7.2.0 and later for Windows require the Microsoft Visual C++ 2012 Redistributable Package be installed. This can be downloaded from the following locations: 64-bit Microsoft Visual C++ 2012 Redistributable Package (x86_64) Appropriate environment variables should be set before any of the steps below -- Determine the root location for your Virtuoso installation. For best results, we recommend putting the ZIP (and/or the directory created upon its extraction) into the C:/Program Files/ (or C:/Program Files (x86)/, for a 32-bit Virtuoso on 64-bit Windows) directory. If you have installed other components from OpenLink Software, you may want to add the Virtuoso subdirectory to that directory (e.g., C:/Program Files/OpenLink Software/VOS7/). Start the System control panel (right-click My Computer and select Properties, or drill down through the Start menu -> Control Panels -> Administrative Tools -> System). Click to Advanced -> Environment Variables, and create a new system environment variable called VIRTUOSO_HOME, with this path (e.g., C:/Program Files/OpenLink Software/VOS7/virtuoso-opensource/) for its value. Locate the PATH system environment variable, and click to EDIT it. Add the string below to the end of the existing PATH value. IMPORTANT: Do not over-write the existing PATH value! Doing so will disrupt all use of your Windows environment. ;%VIRTUOSO_HOME%/bin;%VIRTUOSO_HOME%/lib Click OK or Exit buttons until you have fully exited the System control panel. The above environment variable changes will have immediate effect on any processes that start hereafter, but rebooting your Windows environment may be necessary in some situations. Basic Installation Simply unzip the binary distribution zip file to your chosen location (see Prerequisites, above). This will create a directory virtuoso-opensource, containing 6 subfolders: bin lib hosting database vad vsp Note: The current Windows binary package is missing a php.ini file, required for PHP run-time hosting support. Please download a copy of this file, and manually place it in the database directory. The default administrator username and password are both dba. We recommend immediately changing the password to secure your database. By default, the Virtuoso server will listen for HTTP connections at TCP port 8890, and for SQL data access (via iSQL, ODBC, JDBC, OLE DB, ADO.NET, etc.) at TCP port 1111. These ports may be changed by editing the virtuoso.ini file. Optional -- Create and Manage Virtuoso Windows Services Start a CMD/DOS session (Start menu -> Command Prompt, or run %SystemRoot%/system32/cmd.exe). Note: On Windows Vista and later (including Windows 7, Windows 8, Windows Server 2008, etc.), you MUST right-click on the "Command Prompt" icon and select the "Run as Administrator" option; else, the CMD session will not have the privileges necessary for the following steps to succeed, even if you are logged in as a Windows Administrator. Verify your Virtuoso binary by typing in the command: virtuoso-t -? Note: we also provide binaries with Java (virtuoso-javavm-t) and .NET CLR (virtuoso-clr-t) hosting support, which should be substituted for virtuoso-t throughout, if such hosting support is required. Run the following command: cd %VIRTUOSO_HOME%/database Create a new Windows Service with the following command -- virtuoso-t +service create +instance "New Instance Name" +configfile virtuoso.ini Note: If you have an existing Virtuoso service, the above will replace it. You can preserve the existing service and add a new one with the following command variant (changing the +service argument from "create" to "screate") -- virtuoso-t +service screate +instance "New Instance Name" +configfile virtuoso.ini Once created, you can manage the Virtuoso service through the standard Windows Services Manager (Start -> Control Panel -> Administrative Tools -> Services or Component Services). It will be listed as OpenLink Virtuoso Server [Instance Name]. You can also use the CMD/DOS commands in the table below. Note that the +instance and +service flags may be replaced by -I and -S, respectively.
