formatter for formatting the output.
Supported formatters are:
|Overrides the configuration setting from /usr/local/etc/dovecot/dovecot.conf and from the userdb with the given value. In order to override multiple settings, the -o option may be specified multiple times.|
|-v||Enables verbosity, including progress counter.|
|Command specific options:|
This option is used to specify an alternative socket.
The options argument is either an absolute path to a local UNIX domain
socket, or a hostname and port
(hostname:port), in order to connect a remote host via a TCP socket.
By default doveadm(1) will use the socket /var/run/dovecot/director-admin. The socket may be located in another directory, when the default base_dir setting was overridden in /usr/local/etc/dovecot/dovecot.conf.
host A mail servers hostname or IP address. ip A directors IP address. port The TCP port, on which the director server is listening for connections. The default port is the same as what the local director is listening in. user Is a users login name. Depending on the configuration, a login name may be for example jane or email@example.com. vhost_count The number of virtual hosts to assign to this server. The higher the number is relative to other servers, the more connections it gets. The default is 100.
doveadm director add [-a director_socket_path] host [vhost_count]
The commands tasks are:
* assign a new mail server to the director. * increase/decrease the vhost_count of an already assigned server.
doveadm director dump [-a director_socket_path]
Dump the current host configuration as doveadm commands. These commands can be easily run after a full director cluster restart to get back to the dumped state.
doveadm director flush [-a director_socket_path] host|all
doveadm director flush drops all user associations either from the given host or all hosts. This command is intended mainly for testing purposes.
doveadm director kick [-a director_socket_path] user
Kick the specified user from the entire Dovecot cluster. This is similar to doveadm proxy kick, but this command needs to be run only once instead of in each director server.
doveadm director map [-a director_socket_path] [-f users_file] [-h|-u] [host]
The command doveadm director map is used to list current user -> host mappings. Note that the director works using 32bit hashes which makes collisions quite likely, so this command cant reliably list exactly which users have recently logged in.
-f users_file Path to a file containing all user names (one per line). When given no userdb lookup will be performed. This may be a helpful alternative when for example the network connection to the LDAP or SQL server is slow. -h Output all usernames, which match the given hash. -u Output hash for the given username. host Specify a servers IP address or hostname, to list only mappings of the given host.
doveadm director move [-a director_socket_path] user host
Move the user to the specified backend host. If the user has any existing connections they will be killed.
doveadm director remove [-a director_socket_path] host
Use this command in order to remove the given host from the director.
doveadm director ring add [-a director_socket_path] ip [port]
Add a new director to the ring.
doveadm director ring remove [-a director_socket_path] ip [port]
Remove a director from the ring.
doveadm director ring status [-a director_socket_path]
Show the status of all the directors currently in the ring.
doveadm director status [-a director_socket_path] [user]
This command is used to show the current usage of all assigned mail servers.
When a user name is given, this command shows which server the user is currently assigned to, where the user will be assigned after the current saved assignment gets removed and where the user would be assigned to if the whole proxy cluster was restarted fresh.
/usr/local/etc/dovecot/dovecot.conf Dovecots main configuration file. /usr/local/etc/dovecot/conf.d/10-director.conf Director specific settings.
Add a director with vhost count 150 (or change existing ones vhost count to 150):
doveadm -v director add x1357.imap.ha.example.net 150 2001:db8:543:6861:143::1357: OK
Remove a director:
doveadm director remove x1357.imap.ha.example.net
Query the status of mail hosts in a director:
doveadm director status mail server ip vhosts users 192.168.10.1 100 125 192.168.10.2 100 144 192.168.10.3 100 115
Query the status of a users assignment:
doveadm director status firstname.lastname@example.org Current: 192.168.10.1 (expires 2010-06-18 20:17:04) Hashed: 192.168.10.2 Initial config: 192.168.10.3
This means that the user is currently assigned to mail server on IP 192.168.10.1. After all of users connections have logged out, the assignment will be removed (currently it looks like at 20:17:04, but that may be increased). After the assignment has expired, the user will next time be redirected to 192.168.10.2 (assuming no changes to director settings). If the entire Dovecot proxy cluster was restarted, so that all of the director configuration would revert back to its initial values, the user would be redirected to 192.168.10.3.
