The JAVAHOME environment variable has to be correctly defined.To accomplish that, press Windows key and Break key together, switch to Advanced tab and click on Environment Variables.Note. Remember the restrictions concerning illegal characters in Java paths, e.Note. In case you have to install Karaf into a very deep path or a path containing illegal characters for Java paths, e.S C your very problematic pathKARAFso your Karaf root directory is S which works for sure and is short to type.Qq. With this flexibility, Karaf is the perfect solution for microservices, systems integration, big data, and much more.Installation on Unix platforms.Note.

For example gunzip apache karaf 4.Note. Remember the restrictions concerning illegal characters in Java paths, e.Post Installation steps.Thought it is not always required, it is strongly advised to set up the JAVAHOME environment property to point to the JDK you want Apache Karaf to use before starting it.This property is used to locate the java executable and should be configured to point to the home directory of the Java SE 7 installation.By default, all Apache Karaf files are gather in one directory the KARAFHOME.You can define your own directory layout, by using some Karaf environment variables KARAFDATA is the location of the data folder, where Karaf stores temporary files.KARAFETC is the location of the etc folder, where Karaf stores configuration files.KARAFBASE is the Karaf base folder.By default KARAFBASE is the same as KARAFHOME.Building from Sources.If you intend to build Apache Karaf from the sources, the requirements are a bit different Hardware 5.MB of free disk space for the Apache Karaf source distributions or SVN checkout, the Maven build and the dependencies Maven downloads.Environment Building on Windows platform.You can get the Apache Karaf sources from git clone https git wip us.Use Apache Maven to build Apache Karaf Note.You can speed up the build by bypassing the unit tests mvn clean install Dskip.Tests.

Apache Karaf supports different start mode the regular mode starts Apache Karaf in foreground, including the shell console.Apache Karaf in foreground, without the shell console.Apache Karaf in background.You can also manage Apache Karaf as a system service see System Service section.Regular mode. The regular mode uses the binkaraf Unix script binkaraf.Windows. Its the default start process.It starts Apache Karaf as a foreground process, and displays the shell console.On Unix binkaraf.Apache Karaf 4. 0.Hit lt tab for a list of available commands.Hit lt ctrl d or type system shutdown or logout to shutdown Karaf.On Windows binkaraf.Apache Karaf 4. 0.Hit lt tab for a list of available commands.Hit lt ctrl d or type system shutdown or logout to shutdown Karaf.Note. Closing the console or shell window will cause Apache Karaf to terminate.Server mode. The server mode starts Apache Karaf as a foreground process, but it doesnt start the shell console.To use this mode, you use the server argument to the binkaraf Unix script binkaraf.Windows. On Unix On Windows Note.Closing the console or shell window will cause Apache Karaf to terminate.You can connect to the shell console using SSH or client see the Connect section in this page.Background mode. The background mode starts Apache Karaf as a background process.To start in background mode, you have to use binstart Unix script binstart.Windows. On Unix On Windows You can connect to the shell console using SSH or client see the Connect section in this page.Clean start. Apache Karaf stores all previously applications installed and changes that you did in the data folder.If you want to start from a clean state, you can remove the data folder.For convenience, you can use the clean argument to the binkaraf Unix script binkaraf.Windows. On Unix On Windows Customize variables.Apache Karaf accepts environment variables JAVAMINMEM minimum memory for the JVM default is 1.M. JAVAMAXMEM maximum memory for the JVM default is 5.M. JAVAPERMMEM minimum perm memory for the JVM default is JVM default value.JAVAMAXPERMMEM maximum perm memory for the JVM default is JVM default value.KARAFHOME the location of your Apache Karaf installation default is found depending where you launch the startup script.KARAFBASE the location of your Apache Karaf base default is KARAFHOME.KARAFDATA the location of your Apache Karaf data folder default is KARAFBASEdata.KARAFETC the location of your Apache Karaf etc folder default is KARAFBASEetc.KARAFOPTS extra arguments passed to the Java command line default is null.KARAFDEBUG if true, enable the debug mode default is null.If debug mode is enabled, Karaf starts a JDWP socket on port 5.You can plug your IDE to define breakpoints, and run step by step.You can define these environment variables in binsetenv Unix script binsetenv.Windows. For instance, to set the minimum and maximum memory size for the JVM, you can define the following values On Unix Content of binsetenv.JAVAMINMEM2. 56. M.JAVAMAXMEM1. MOn Windows rem Content of binsetenv.JAVAMINMEM2. 56. M.JAVAMAXMEM1. MConnect.Even if you start Apache Karaf without the console using server or background modes, you can connect to the console.This connection can be local or remote.It means that you can access to Karaf console remotely.To connect to the console, you can use the binclient Unix script binclient.Windows.
