The problem is caused by the /tmp/ filesystem being mounted noexec, which keeps any programs on /tmp/ from being allowed to be executed, which breaks the install script.

To remount /tmp/ as executable, use:

[root@web1 ~]# mount -o remount,exec,suid /tmp

The it should install correctly.

After the install is done, remount the /tmp/ filesystem with the noexec permissions reset.

[root@web1 ~]# mount -o remount,noexec,nosuid /tmp
