CentOS is my favorite Linux distribution because it is the closest to RedHat you can find (for a reason<\/a>). And I like RedHat for the simple reason that it is the most supported Linux distribution for any enterprise applications. I know usually both RedHat and SuSE are supported, but SuSE and I was never a love story and I will save you the history of this little drama for this time.<\/p>\n

So, the idea is not to run CentOS in a production environment, unless you really have the heart of a warrior and do not care about being supported by a rock solid editor, but instead to run your OnCommand Core lab<\/a> on a free OS.<\/p>\n

I used a CentOS 6 minimal install for this tutorial.<\/p>\n

<\/p>\n

The problem<\/h1>\n

Here is what happens if you try to install the package right away after downloading it from NetApp download site :<\/p>\n

# chmod 755 occore-setup-5-2-linux-x64.sh \n# .\/occore-setup-5-2-linux-x64.sh \nPreparing to install OnCommand Core Package\nUnpacking files needed for the installation ...\nerror: This is not a supported platform.<\/pre>\n
See ? We will have to trick the installer to force the installation<\/p>\n
The solution<\/h1>\n
[EDIT] Thanks to Hadrian in the comments, there is actually a very simple way :<\/p>\n
# .\/occore-setup-5-2RC1-linux-x64.sh -o<\/pre>\n
That’s it !<\/p>\n
I leave the rest of the original article for the archives !<\/p>\n
The trick is just to interrupt the installer before it gets a chance to remove the uncompressed installation folder, the easiest way I found to do that is to use gdb (the linux debugger) and break on \u00ab\u00a0unlink()\u00a0\u00bb which is the C function that removes files on disk. It sounds complicated like this, but it is really trivial, as you can see : (you might have to install gdb with \u00ab\u00a0yum install gdb\u00a0\u00bb if it is not present on your system)<\/p>\n

At this point, the installer will run and just stop when it tries to remove temporary files<\/p>\n
Starting program: \/root\/occore-setup-5-2-linux-x64.sh \nPreparing to install OnCommand Core Package\nUnpacking files needed for the installation ...\nDetaching after fork from child process 2020.\nerror: This is not a supported platform.\n\nBreakpoint 1, 0x00007ffff7b343b0 in unlink () from \/lib64\/libc.so.6\nMissing separate debuginfos, use: debuginfo-install glibc-2.12-1.7.el6.x86_64\n(gdb) q<\/strong>\nA debugging session is active.\nInferior 1 [process 2017] will be killed.\nQuit anyway?

Here we just quit with \u00ab\u00a0q\u00a0\u00bb and confirm to do so with \u00ab\u00a0y\u00a0\u00bb.<\/p>\n
Ok, now let’s move the installer to a safer place :<\/p>\n
# mv \/tmp\/dfmsetup-*\/ ~\/dfmsetup\n# cd ~\/dfmsetup<\/pre>\n
Now we just have to edit the installation script and disable the system check.<\/p>\n
Just edit dfmsetup.sh and change the line :<\/p>\n
check_os_flag=1<\/pre>\n
with<\/p>\n
check_os_flag=0<\/pre>\n
Now you can run the installer :<\/p>\n
Note that \u00ab\u00a0NTAPdfm\u00a0\u00bb here is whatever the RPM package is named before the version string. For example, mine is called : NTAPdfm<\/strong>-5.2-16233.x86_64.rpm.<\/p>\n
If you are instaling an OEM release like IBM’s, it might be different.<\/p>\n
