I am using cloudify 2.7, the byon.xml config jdk is 1.6 bin, but now, my application need jdk 1.7, so I want to download jdk 1.7 bin version, but I did not find it, so I config jdk 1.7 gz and tar version in byon.xml, but cloudify agent can not install it. I read cloudify document write: /* The following optional attribute contains the path from which the JDK will be downloaded. Default Linux values are : 32 bit http: //repository.cloudifysource.org/com/oracle/java/1.6.0_32/jdk-6u32-linux-i586.bin 64 bit http: //repository.cloudifysource.org/com/oracle/java/1.6.0_32/jdk-6u32-linux-x64.bin But you can set it manually as follows : (If you want to rely on the pre-installed JDK, set javaUrl to "NO_INSTALL") */ javaUrl "http: //my-pc:8080/java.bin"
so my question is how can I use cloudify pre-install jdk 1.7?
Cloudify uses Oracle JDK 6, though it should work using any compatible JDK.
As this is the JDK that Cloudify was tested with, I recommend that you keep using JDK 6 to run Cloudify, and install JDK 1.7 separately for your application. Cloudify does not install JDK 6 at the system level - it is not installed as a system package (like apt or yum) - it is just a tar/zip that is uncompressed. So you can simply have a preInstall lifecycle script that installs JDK 7, either at the system level or the user level.
Once JDK 7 is installed, you will probably need to edit your start script to add the JAVA_HOME environment variable and add the bin directory of JDK 7 to the PATH environment variable. This will not interfere with Cloudify's agent.
