Background for Course 1901 Capstone
Background: You need to know this
Easiest: 11.3
You need these running:
Server2012R2 (DNS/NFS/CIFS server, it's at 10.1.1.1),
11.3server (this is broken!)
We have an old application, written for an earlier version
of Linux.
It is stored on a central NFS server:
server2012r2:/exports/oldprogram
and there's also CIFS service if that's easier:
//server2012r2/smbshare
However, we have reformatted and upgraded our servers. Resulting problems:
- The oldprogram is a 32-bit application compiled for CentOS 5. It will not run.
- The oldprogram should be kept on the Windows Server2012R2 for easy upgrades. Preferably, do not copy it to your Linux server.
- Passwords may not be stored in /etc/fstab .
- The permissions on oldprogram are wrong in the exports directory
Middle: 11.1
You need these running:
Server2012R2 (DNS server),
11.1client (use this for testing),
11.1server (this is broken!)
11.1client works fine.
Web site should be at:
http://artwork.course1901.local/
and artwork.course.1901.local should be at 10.1.1.111.
The genius has:
- Worked on the web site on his network at home, which is not at all like the corporate one.
- Temporarily turned off SELinux, which means it may or may not be enabled now, and if so, is probably wrong.
- Temporarily turned off the firewall, which means it may or may not be enabled now, and if so, is probably wrong.
- Created the web site in /home/website.
- Deassociated the computer from the company AD domain, and added a local unixuser account.
Hardest: 11.2
The server suffered a catastrophic power failure while writing to disk during a kernel upgrade. So:
- The /boot file system is overwritten with garbage.
- The swap file system (on /dev/rhel/swap) is also corrupted, no swap signature.
- The XFS signature on the root file system has been overwritten.
- The grub boot loader cannot find anything to load.
- Starting a rescue from the DVD, it says you do not have any partitions.
- At least the system was set up for BIOS compatability mode so that's a little less complicated than it might be.
