HDP on Linux – Installation Forum

Problem installing HDP 1.0: missing dependencies

  • #5886
    Carter Shanklin

    I tried following the instructions on installing HDP 1 but “yum install hmc” fails because of 2 missing dependencies.

    My full set of steps consisted of:
    . Install of a single fresh CentOS 5.6 VM from ISO
    . Ran “yum update”
    . Added the HDP and EPEL repos as per instructions.
    . Ran “yum install php-pecl-json” with success
    . Ran “yum install hmc” without success.

    The missing dependencies are pdsh and mod_passenger. Quick search shows pdsh appears to be in repoforge rather than EPEL. I’m not sure what repo hosts mod_passenger. Are there steps missing from the instructions? Also it would help to clarify the required software stack, e.g. is CentOS 5.6 an OK starting point, I used it because it appeared it would work and I had the ISO handy.

    Hi Carter,

    Sorry that you’re having this installation problem. We’ll look into it and get right back.

    Thanks for giving HDP 1.0 a look.

    Thanks for trying out HDP. Looks like some of the dependencies in 5.6 are having issues. Can you please try this out – basically install the rpmforge and passenger repo to see if the dependencies resolve.

    rpm -Uvh
    rpm -Uvh

    I am trying out on a 5.6 image and will report my findings. We have tried it on quite a few centos 5 images and did not have an issue with this, so 5.6 should be an acceptable image.


    Hi Carter,

    I just downloaded the CentOS 5.6 ISOs from and installed it on my local VM, CDs 1 thru 6. Here is the steps I performed as root after that:
    % rpm -Uvh
    % rpm -Uvh
    % yum install php-pecl-json
    % yum install hmc
    The commands all completed successfully. Packages “pdsh” and “mod_passenger” were downloaded off from the “HDP-” repository.
    Can you paste the output of command “uname -a”?

    Hello Carter,
    Are you running 32bit 5.6 CentOS or 64bit?

    FWIW, same problem on CentOS 5.8 32-bit (missing Passenger and pdsh) and fixed it more or less as described above:
    # uname -a
    Linux localhost.localdomain 2.6.18-308.11.1.el5 #1 SMP Tue Jul 10 08:49:28 EDT 2012 i686 i686 i386 GNU/Linux
    # rpm -Uvh
    # rpm -Uvh
    # yum install pdsh
    # yum install hmc
