I am trying to make a render farm on CentOS 7, which will probably be slow, but it will be working 7/24, and I want to use my university's remote server for that purpose.

  • I have no admin permissions, but I've downloaded the blender tar.xz file and unpacked it, however ./blender --help gives a permission denied error

How can I set up a system to render my .blend file on my local space given by the university?

  • Is the `blend` file marked as executable (+x) in its file permissions? Do you know whether the server's admins allow users to run their own software? (Have you tried asking them about this problem?) If you copy a regular binary (e.g. /bin/whoami or /bin/id) to your home directory and try to run that, does it work or do you get the same error message? – u1686_grawity Jul 12 '21 at 11:49
  • ''file blender'' tells me it is executable. – Kayra Uckilinc Jul 12 '21 at 11:51
  • `file` describes the file's contents, it doesn't tell you anything about permission bits. Try `ls -l`. – u1686_grawity Jul 12 '21 at 11:52
  • i cannot ask them about this but if i can make them happen it all good, necer tried running regular binary files have nothing to test on atm. I can run my own c++, python codes – Kayra Uckilinc Jul 12 '21 at 11:52
  • Usually C++ compilers output regular binary files. If you can run those, you _should_ be able to run Blender from the same location, so it's most likely just a problem with the specific file's permissions. (Though if you're given access to several distinct directories, like /home vs /scratch vs /tmp, it's still possible that some of them allow programs to be executed while others have noexec set.) – u1686_grawity Jul 12 '21 at 11:53
  • -rw-r--r--. 1 is written besides my blender, executable file, whats my best shot then? – Kayra Uckilinc Jul 12 '21 at 11:53

Files, regardless of their contents, are only allowed to be executed if you have the x permission on them.

If you're the owner of the file, use chmod to change its permissions:

chmod a+x blend

The .exe file will start the installation. Choose where to install Blender and set MS-Windows to run in the menu, and you can already open .blend files using Blender. You must have administrator rights on your operating system to install Blender. It creates many frames over multiple machines so that you don't burden your PC. If you use a .zip file, you unzip it manually to the folder you want to use. From there, you double-click on the executable file to start Blender. With this option, you can have multiple versions of Blender without conflict, as they are not actually installed on the system.

  • Question is about Linux. – Toto May 29 '22 at 16:06
  • -1 because the title says it's about Linux, the first sentence says it's about Linux, comments are Linux-centric and an accepted answer for Linux was posted a year ago, yet you've posted about Windows. This answer is obviously wrong. – gronostaj May 29 '22 at 18:46
