Comment: dropdb
Deletions are marked like this. Additions are marked like this.
Line 78: Line 78:
The `createdb <DBNAME>` command creates a database named `<USERNAME>_<DBNAME>`. The `createdb <DBNAME>` command creates a database named `<USERNAME>_<DBNAME>`, and `dropdb <DBNAME>` drops a database. For security/accounting reasons, you won't be granted permissions to drop a database in the usual way, through an SQL session.

For the purposes of this page, we'll use the name New to refer to the servers hosted at Peer 1 (which are deleuze, mire, and eventually abulafia) and Old to refer to any servers that we've used previously.

Note: We are in the process of migrating people who have signed up as guinea pigs. We are not currently accepting new domain requests or providing help to non-guinea-pigs. This will change once we have made reasonable progress in working out the kinks of the new setup.

Summary of what exactly is going on here

We are now offering limited-access accounts on the new infrastructure (see NewServersSetup) on a "beta test" basis to all users who have accounts on fyodor. These accounts come with no uptime or service guarantee; during the next few weeks we may need to temporarily disable them from time to time. Please do not use them for anything important.

These accounts will allow you full access to your space in AFS (currently 400MB per user) and the ability to log in to mire.hcoop.net via ssh. Currently NO OTHER SERVICES are officially supported on the new infrastructure (for example, email or serving HTTP), although we hope to make these available soon.

Requesting an account on the new infrastructure will not affect your fyodor account. You will have access to both accounts until after all migration is complete.

Step 1: Get a mire account

We have created a file in each fyodor user's home directory called .mire-password. This file is readable only by you and the admin who will be processing the account creations.

If you would like to get a mire account, please put your desired password in the file ~/.mire-password. Please be VERY careful not to delete this file or change its permissions. The recommended procedure is to type:

cat > ~/.mire-password

and then type your desired password, press enter, and then press control-D. After you do this, please run the command:

ls -l ~/.mire-password

and make sure that the permission bits are -rw-rw---- (user and group can read and write) and the group for the file is set to megacz.

We will be running an account-creation script approximately once a day. After you put your password in ~/.mire-password, your account will be created the next time the script is run, typically no more than 24 hours after you specify your password. An email will be sent to your hcoop account to let you know that your account has been created. Your .mire-password file WILL BE DELETED when your account is created, so please make sure you memorize it before writing it to the file.

Step 2: Try logging in

If you've always been typing a password to log in via SSH and don't care to do otherwise, then you don't need to bother reading this section!

You can't use SSH public key authentication anymore. Kerberos authentication ("ssh -K") is supported, for passwordless log-in. Some day, someone might implement the Kerberos support needed to make SSH public key auth work again. See RealSecurity for more information on all of this.

Step 3: Visit the new portal

[https://members2.hcoop.net/ The new portal] uses the same password you use to log in to mire. That is, if you haven't created a mire account yet, then you can't access the new portal.

You should use the new portal for all administrative requests related to the new servers, except for...

Step 4: Have your mail dual-delivered

We recommend that you tell fyodor to dual-deliver all of your mail so that one copy goes to deleuze and one copy goes to fyodor. That way you can start reading your email via deleuze, but if anything goes wrong you can just switch back to fyodor.

To do this, put the following lines in your ~/.forward file on fyodor. Note that the comment on the first line is mandatory -- it tells exim that this forward file uses special exim features. If your username was fred, you would put this in your ~/.forward:

  # Exim filter
  deliver fred
  deliver fred@deleuze.hcoop.net

and you mail will be dual-delivered.

Step 5: Copy your existing email

You can also copy the contents of your mailboxes from fyodor to deleuze. To do this, log in to fyodor and type:

  rsync -are ssh --no-g --progress --verbose ~/Maildir/ mire.hcoop.net:Maildir/

Bugzilla

We have a [https://bugzilla.hcoop.net/ Bugzilla] that we are using for managing support requests that don't fit into the special categories handled by the portal. If you've completed the migration steps above that create your mire account, then you can use the same username and password to access Bugzilla. You can also start from the portal, which links to Bugzilla from the support page.

Databases

Here lie interim dbtool docs until migration is done, at which time they will probably move to UsingDatabases.

To manage your database user and databases, the basic syntax is dbtool <DBTYPE> <COMMAND>, where <DBTYPE> is postgres or mysql.

The adduser command creates a database user for you, with the same name as your UNIX log-in name. In the case of mysql, you will be prompted for a password and confirmation re-entry in the usual manner.

The passwd command allows you to reset the password. (Useless for postgres, where we use only ident authentication)

The createdb <DBNAME> command creates a database named <USERNAME>_<DBNAME>, and dropdb <DBNAME> drops a database. For security/accounting reasons, you won't be granted permissions to drop a database in the usual way, through an SQL session.

To access your database use the following on mire: mysql -p -h deleuze or psql -h deleuze USERNAME_DBNAME

DNS

We are purposely not sending any DNS data from New to Old, which means that you need to change domains at your registrar if you want New to be authoritative for them. The proper nameservers are ns1.hcoop.net and ns3.hcoop.net, in that order. Keeping ns.hcoop.net and ns2.hcoop.net will not work.

Domains

See the DomTool page for instructions on managing your domains with the new setup. The configuration files are in a vastly different format, but they have a better-defined syntax that should be relatively easy to understand.

Home

Your home directory is now managed by AFS. You will enter it by default when logging in to mire.hcoop.net via ssh. Type pwd to see what the path is. It will look like /afs/hcoop.net/user/u/us/username. Some directories have been created for you already, so that they have the correct permissions for things like serving web pages and delivering mail.

Email

.forward

~/.forward files should have the same effect that they do with our old setup.

IMAP

SSL IMAP is available via SSL at port 993, using hostname deleuze.hcoop.net.

STARTTLS IMAP is available on port 143, using hostname deleuze.hcoop.net.

POP3

POP3 access is available via SSL at port 995, using hostname deleuze.hcoop.net. If you're using Thunderbird, make sure to uncheck "Use secure authentication". Do not use port 110; it is not available, because no good way of securing normal POP3 has been found by the admins.

procmail

The page ProcmailExample has been updated for the new setup. Basically:

  • Use the file ~/.procmail.d/procmailrc instead of ~/.procmailrc.

  • Write any procmail logs in ~/Maildir rather than elsewhere.

  • Use appropriate values for the HOME, MAILDIR, and DEFAULT options, based on those in ProcmailExample.

Virtual mailboxes

The vmail program from fyodor has been updated for the new servers. Here's a quick run-through of how to invoke the new version. Like before, you always invoke it with vmail $DOMAIN $COMMAND, which indicates that you are configuring the virtual mailboxes for domain $DOMAIN for which you have DomTool permissions. The valid commands are:

  • list: Print the mapping from usernames to mailbox directories for $DOMAIN.

  • add $USER $MAILBOX: Add a mapping from $USER@$DOMAIN to a Maildir directory $MAILBOX. You'll be prompted to enter a password for the user, which he can then use to access IMAP, POP, or restricted SMTP services.

  • passwd $USER: Reset a virtual user's password.

  • rm $USER: Remove a mapping. The mailbox directory remains for you to deal with as you like.

rsync

If you're using rsync to transfer data to the new servers, the "-a" option by itself won't work properly because rsync attempts to chgrp the transferred files. Use "-a --no-g" instead of "-a".

security

See RealSecurity for some notes on security.
