NAME
master - master Cyrus process
SYNOPSIS
master [ -C alternate imapd.conf ] [ -M alternate cyrus.conf ] [ -l
listen queue ] [ -p pidfile ] [ -P snmp agentx ping interval ] [ -j
janitor period ] [ -d ] [ -D ] [ -x snmp agentx socket ]
DESCRIPTION
Master is the process that controls all of the Cyrus processes. This
process is responsible for creating all imapd, pop3d, lmtpd and sieved
child processes. This process also initializes the Berkeley DB code and
performs scheduled cleanup/maintenance.
If this process dies, then no new sessions will be started.
It kills itself and all child processes when it receives a SIGTERM.
OPTIONS
-C alternate imapd.conf
Specifies an alternate imapd.conf for use by master (note that
this will not affect any sub-processes spawned by master, you
should specify those specifically in the respective entries in
cyrus.conf).
-M alternate cyrus.conf
Specifies an alternate cyrus.conf for use by master.
-l listen queue backlog
Increase the listen queue backlog. By default, the listen queue
is set to 32. On systems with a high connection rate, it may
be desirable to increase this value. refer to listen(2) for
details.
-j janitor full-sweeps per second
Sets the amount of times per second the janitor should sweep the
entire child table. Leave it at the default of 1 unless you
have a really high fork rate (and you have not increased the
child hash table size when you compiled Cyrus from its default
of 10000 entries).
-p pidfile
Use pidfile as the pidfile. If not specified, defaults to
/var/run/cyrus-master.pid
-P snmp agentx ping interval
Sets the amount on time in seconds the subagent will try and
reconnect to the master agent (snmpd) if it ever becomes (or
starts) disconnected. Requires net-snmp 5.0 or higher.
-d Start in daemon mode (run in background and disconnect from con-
trolling terminal).
-D Don't close stdin/stdout/stderr. Primiarly useful for debugging.
-x snmp agentx socket
Address the master agent (most likely snmpd) listens on.
Requires net-snmp 5.0 or higher.
CONFIGURATION
Upon execution, master reads its configuration information out of the
cyrus.conf(5) file.
Master rereads its configuration file when it receives a hangup signal,
SIGHUP. Services and events may be added, deleted or modified when the
configuration file is reread. Any active services removed from the
configuration file will be allowed to run until completion.
NOTES
The environment variable CYRUS_VERBOSE can be set to log additional
debugging information. Setting the value to 1 results in base level
logging. Setting it higher results in more log messages being gener-
ated.
