NAMEcyrus-master - cyrus-master Cyrus process
SYNOPSIScyrus-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
Cyrus-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 cyrus-master (note
that this will not affect any sub-processes spawned by cyrus-
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 cyrus-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 cyrus-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 cyrus-master agent (most likely snmpd) listens on.
Requires net-snmp 5.0 or higher.
CONFIGURATION
Upon execution, cyrus-master reads its configuration information out of
the cyrus.conf(5) file.
Cyrus-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.
