Instructions for setting up the databse on a new boss node. Not quite complete,

but a good start.

This document is geared towards non-federated sites. Many of the steps
herein (such as creating node types and interface types) will probably
happen through some other database replication method once we're
federating testbeds rather than creating disconnected clones.

##### Setting up tbdb for a new boss node
##### Last updated January i18, 2002
##### Step 0 - Create the database
Before beginning this process, you should have mysql installed and running on
your boss node.
Create the database. You can do this with the database-create.sql file in the
sql subdirectory of the testbed tree, like so:
mysqladmin create tbdb
mysql tbdb < sql/database-create.sql
It's a good idea to contact Utah to make sure that the database-create.sql file
is up-to-date.
##### Step 1 - Setup users
You'll need to start by creating an admin user. Currently, there is no
automated way to do this - the easiest thing to do is conact Utah and ask for
an example entry. We hope to remedy this problem before too long.
At this point, it's a good idea to get the nfs mounts between boss and ops
setup, as well at the ssh root keys. See the boss and ops setup documents for
details.
Run 'mkacct <username>' for the user you just created. This will set up a Unix
account for them on the boss and ops nodes.
If you want to make sure that this account is a member of any Unix groups (such
as wheel,) run 'unixgroups -a <uid> <gid> ...'
##### Step 2 - Setup projects and experiments
At this point, you should get the webserver up and running on your boss node.
Again, instructions are in the boss setup documentation.
Go to the web interface, and log in as the admin account you created. Create
two projects: One for the administrators at your site (we call ours 'testbed'),
and another meta-project called 'emulab-ops'. As soon as you've sent the
request to sart each project, you can just use the 'New Project Approval' link
to make them active.
Others at your site can now apply to join your project.
There are three experiments that must be created in the emulab-ops project.
Just start them through the normal 'begin experiment' page, and don't give an
NS file. These experiments are:
hwdown - Nodes that are down due to hardware failure
reloading - Nodes that are having their disks automatically reloaded
readpending - Nodes that are awaiting disk reloading
Any other 'holding' experiments that you want for operations should be put
into the emulab-ops project.
##### Step 3 - Setup web sql editor
Several of the steps below require you to add data to the database by hand. If
you're comfortable with SQL, you can do this directly with SQL queries, or you
can use the generic web-based SQL table editor provided with the testbed
software. If you plan to use the former method, you can skip this step.
********************************** WARNING **********************************
* Many tables depend on data in other tables, or depend on programs running *
* to effect a change. Thus, you should not edit tables other than the ones *
* described in this document. *
* You have been warned...... *
********************************** WARNING **********************************
First, you'll want to protect the webdb script from outside browsers. Because
of its flexibilty, it would be quite dangerous if it were broken into. So, we
add an additional layer of protection by limiting the IP addresses it may be
used from. Open your apache.conf file (created as part of the boss
installation), and find the 'Directory' directives. Add a section such as
this:
<Directory /usr/testbed/www/webdb>
AllowOverride None
order deny,allow
deny from all
allow from 155.99.212.
</Directory>
If you installed the testbed tree somewhere other than /usr/testbed, fix the
directory. Chage the 'allow from' line to match your IP subnet (note the '.'
on the end of the address, to match the entire subnet). You can have as
many 'allow' lines as you want. Restart apache.
Next, you'll need to specify which users have the ability to edit the database.
This is done with the 'dbedit' column in the users table. When we automate
user creation, we'll add a way to set this when the user is created.
Now, you'll need to specify which tables are editable from the web interface.
This is to protect against accidental database damage, as mentioned in the
warning above. We'll soon provide contents for this table
(webdb_table_permissions) with the testbed software.
##### Step 4 - Setup switches
1) Create node types for switches
Add entries to the node_types table for each type of switch you'll be using.
The class column should be 'switch', and choose a type that reasonably
describes the switch. Most of the other columns aren't important for switches
(so you can leave them blank), but putting in max_cards (if the switch is
expandable) and max_ports is a good idea.
2) Create interface type for the switch IP interfaces
Now, go into the interface_types table and add interface types for your
switches' IP interfaces. Since these are logical interfaces, not real ones,
most of the information here is unimportant.
3) Create interface types for switch interconnects (if any)
If you'll be connecting switches together, also add interface types for the
ports you'll be using to link them together. Unlike the logical IP interfaces,
make sure that you get physical information like speed (in Kbps) and duplex are
correct.
4) Create switches in nodes table
Next, add the switches to the nodes table. The only necessary fields here are
node_id (choose one appropriate to the switch), type (use one of the ones you
created earlier,) and role. Role, for switches, should be either 'testswitch'
or 'controlswitch', depending on whether you're using it for the
experimental or control network.
5) Create interfaces for switch IP interfaces
In the interfaces table, add an interface for the IP address of each switch.
The important columns are node_id, IP, and interface_type. card and port should
be set to values that will not be used by actual ports on the switch (they
could both, for example, be 0)
6) Add state for switch interconnects
If you'll be connecting switches together, add interfaces to each of them.
Unlike the previous interfaces, make sure that you get the correct card and
port numbers. For switches that do not have expansion modules, the card number
is assumed to be 1. Make sure to get the current_speed (this time, in Mbps) and
duplex correct.
Now, go into the wires table and add wires connecting the switch interfaces you
just created. Make sure to set the type to 'Trunk'. In this case, it doesn't
matter which switch you use as node 1 (the node_id1, card1, port1 columns), and
which you use as node 2.
7) Create switch stacks
Into the switch_stack_types table, create entries for each stack in your
network. A stack is set of switches that share common VLANs. Usually, your
experimental switches will be one stack, and the control network another. You
should create a stack even if there is only one switch in it. The stack should
be named (the stack_id column) after the master switch in the stack. In our
case, for example, our experimental network stack is called 'cisco1'. The
stack_type column is used by snmpit to determine which module to use to talk to
the stack. The currently supported values are 'cisco' and 'intel'. Making a
control network stack is optional.
Finally, add switches to these stacks by putting entries in the switch_stacks
table, listing the node_id of each switch and the stack_id of the stack it
belongs to.
##### Step 5 - Setup control hardware
1) Boss/ops nodes
Optional step: You can put your control (boss and ops) nodes in the database if
you wish. You'll need to add entries to the nodes, interfaces, and wires
tables, and possibly the node_types and interface_types tables as well. See the
instructions for adding nodes below for descriptions of the contents of these
tables.
2) Power controllers
The only two supported power controllers at this time are the APC AP9210 and
the BayTech RPC27. Theoretically, other SNMP and serial-controlled power
controllers should not be hard to support.
If your power controllers are controlled via IP and SNMP, add a node type ander
interface type for them. Then, give them an entries in the nodes, interfaces,
and wires tables. Make sure to get the IP address correct in the interfaces
table. The role listed in the nodes table should be 'powerctrl'.
If you have serial power controllers, just create entries node_types and nodes
- no interfaces or wires. Again, the role in the nodes table should be
'powerctrl'.
##### Step 6 - Images and OSids
These will depend on the image(s) and any OSKit kernels you've recieved, or
built yourself. Since you're probably using disk images from Utah, the best
thing to do is ask us for the appropriate lines for the os_info and images
tables.
##### Step 7 - Setup nodes
1) Create node type for the nodes
Add an entry to the node_types table for each type of experimental node you
have. Most of the columns should be self-explanatory, but here are some notes:
class: Should be 'pc'
type: Shoud be 'pcXXX', where XXX is a short (a few characters) string
describing the nodes (such as processor speed, chipset, etc.)
proc: Class of processor (ie. 'PIII')
speed: CPU speed in MHz
RAM: Amount of RAM in MB
HD: Hard disk size in GB
max_cards: Number of PCI (or ISA) slots
max_ports: Maximum number of NIC ports (eg. dual port cards count as 2)
osid: Default operating system to use. Should be one of the ones created in
Step 6
control_net: Interface number (described below) of the control network
interface
power_time: Number of second between power cycles (to help save wear and tear
on the hardware). We recommend 60.
imageid: Default image to load (created in Step 6)
delay_capacity: How many delay nodes this node can be. For example, nodes with
2 experimental interfaces can be 1 delay node, nodes with 4 experimental
interfaces can be 2 delay nodes, etc.
control_iface: Linux-style interface name for the control network (ie. 'eth0')
delay_osid: Which OS should be run when this node is being a delay node.
Should usually be 'FBSD-STD'
pxe_boot_path: Path (including hostname) to the mini-kernel that should be
loaded by PXE. Ask Utah for this kernel. For example,
'boss.emulab.net/tftboot/pxeboot'
2) Create interface types for the nodes
Add entries to the interface_types table for each type of network card you are
using. Notes on the columns:
type: So far, we have been using FreeBSD driver names for types, but this
string is arbitrary
max_speed: The maximum speed of the interface, in Kbps
full_duplex: 1 if the card can operate in full duplex, 0 otherwise
