Ansys install problem

Post by Emanuele » Tue Mar 18, 2014 18:27

Hi,
I need to have ansys installed in my laptop for my university activities. I have the two .iso files provided by the univeristy.
When i try to run the ./INSTALL script that what i get:
# ./INSTALL
copying necessary files to /tmp/ans_install_tmp7305/
./INSTALL: line 278: /tmp/ans_install_tmp7305/INSTALL: Permission denied
./INSTALL: line 278: exec: /tmp/ans_install_tmp7305/INSTALL: cannot execute: Permession denied
I tried to copy the .iso contnent into my home dir and change the INSTALL permissions with "chmod 777" as written here: http://ubuntuforums.org/showthread.php?t=1783646

I even tried to follow the same path i followed to successfully install Matlab:
# chmod u+x INSTALL and then running it as
# /home/.../INSTALL -root /home/.../ansys1/ -tmpdir /home/emanuele/AnsysTemp

But nothing seems to work, i hope it's just something easy to solve that i didn't get...

It sounds like it's copying files to /tmp/ans_install_tmp7305/, but then the INSTALL file located at /tmp/ans_install_tmp7305/ doesn't have the right permissions.

After you attempt to run it, what is the output of:

Code: Select all

ls -la /tmp/ans_install_tmp7305/
The security settings of /tmp/ are kind of hard to understand, and they've changed in the past few years, which could be part of the problem. Nothing that can't be worked around though.

Ok, the output is quite long so i wiped everything but what concern ansys.
I ran:
tmp # ls -l
...
drwxr-xr-x 6 root root 480 19 mar 09.11 ans_install_tmp4510
...
And then:
# ls -la /tmp/ans_install_tmp4510/
....
drwxr-xr-x 6 root root 480 19 mar 09.11 .
drwxrwxrwt 13 root root 360 19 mar 09.11 ..
-rwxr-xr-x 1 1659 dialout 8234 7 ott 2011 .ans_uninstall.sh
drwxr-xr-x 2 root root 100 19 mar 09.11 config

Very interesting. I think the best way I can help is if I attempt to install it myself, although obviously I won't have a license so I won't be able to help with many run time issues. I'll see if I can't try that out tonight.

I've found somebody who's successfully installed it in the past, so it should be able to be done: http://www.cfd-online.com/Forums/cfx/25 ... post361733

I see a lot of people installing ansys with a noroot option.

./INSTALL -noroot

Make sure you're installing it in your home directory.

Unfortunately, I don't know of any way for me to attempt to install this software, so it's hard for me to fully help out.

I've seen some people who have /tmp mounted as noexec, thus you can't run things out of /tmp.

In which case, try moving the directory (/tmp/ans_install_tmp7305/) /home/<user>/ans_install_tmp7305/, then run ./install.

A lot of install scripts have a way to change the tmp directory they use, but it's impossible for me to know for yours atm. You might only need to do something like:
# ./INSTALL -noroot -tmpdir /home/<user>/ansys_install/

or you could attempt to remount /tmp as exec. All of this is assuming that's actually the problem...

Ok, the -tmpdir command semmes to don't work for me, anyway i've got it done editing fstab and changing the noexec option to exec.

Thanks
