Agenda • MongoDB and Windows • Client on Windows • Productions Customers 

Database on Windows • Installing • Deploying • Monitoring • Known issues • Building 

MongoDB on Windows • It really works  • Server or client or both can be on Windows 

Database on Windows • Current production release is 2.0 • Prebuilt binaries for 32 and 64 bit • Released the same time as other OS’ • http://www.mongodb.org/downloads • 64 bit recommended and to be used in production • Windows feature set on par with other OS’ 

Installing on windows • Unzip package • Create c:\data\db to use default directory or use –dbpath • Start mongod – c:\\bin\mongod.exe • Same options as in non-Windows environment 

Deploying • Usual mongod deployment best practices still hold • Always run with replica sets for HA and data safety • Run with journaling • Etc. • Run your database process as a service 

mongod.exe as a windows service • Inbuilt service support in mongod • --install (uses Local System Account) • --remove • Run as admin in Win7, Win2k8 • Other options • --serviceName • --serviceUser • --servicePassword • Ensure service user has access to dbpath 

mongos.exe as a windows service • No support on mongos.exe currently • Can run mongos.exe as a service using srvany.exe • https://github.com/sridharn/MongoWindows

Known Issues • --fork does not work • Log rotation does not work on windows • No inbuilt support for running mongos as a windows service 

Building on windows • Source at http://github.com/mongodb/mongo • Get prebuilt spidermonkey • https://github.com/dwight/vc2010_js • Install on the same level as mongo • Get prebuilt boost libraries • http://www.mongodb.org/pages/viewpageattachm ents.action?pageId=12157032 • Install on root – actual files are at c:\boost\boost\... 

Building on windows contd. • Build using Visual Studio 2010 • …\mongo\db\db_10.sln • Great for navigating source code • Build using scons • Run the right vcvars.bat • --64 – for 64 builds • Build the c++ driver • scons --mongoclient 

Client on Windows • Can connect to server running Windows or other OS’ • Drivers work on Windows (e.g.) • C# • Python • Java • Perl
