14
16 Cyrus-master is the process that controls all of the Cyrus processes.
17 This process is responsible for creating all imapd, pop3d, lmtpd and
18 sieved child processes. This process also initializes the Berkeley DB
19 code and performs scheduled cleanup/maintenance.
20
21 If this process dies, then no new sessions will be started.
22
23 It kills itself and all child processes when it receives a SIGTERM.
24
26 -C alternate imapd.conf
27 Specifies an alternate imapd.conf for use by cyrus-master (note
28 that this will not affect any sub-processes spawned by cyrus-
29 master, you should specify those specifically in the respective
30 entries in cyrus.conf).
31
32 -M alternate cyrus.conf
33 Specifies an alternate cyrus.conf for use by cyrus-master.
34
35 -l listen queue backlog
36 Increase the listen queue backlog. By default, the listen queue
37 is set to 32. On systems with a high connection rate, it may
38 be desirable to increase this value. refer to listen(2) for
39 details.
40
41 -j janitor full-sweeps per second
42 Sets the amount of times per second the janitor should sweep the
43 entire child table. Leave it at the default of 1 unless you
44 have a really high fork rate (and you have not increased the
45 child hash table size when you compiled Cyrus from its default
46 of 10000 entries).
47
48 -p pidfile
49 Use pidfile as the pidfile. If not specified, defaults to
50 /var/run/cyrus-master.pid
51
52 -P snmp agentx ping interval
53 Sets the amount on time in seconds the subagent will try and
54 reconnect to the cyrus-master agent (snmpd) if it ever becomes
55 (or starts) disconnected. Requires net-snmp 5.0 or higher.
56
57 -d Start in daemon mode (run in background and disconnect from con‐
58 trolling terminal).
59
60 -D Don't close stdin/stdout/stderr. Primiarly useful for debugging.
61
62 -x snmp agentx socket
63 Address the cyrus-master agent (most likely snmpd) listens on.
64 Requires net-snmp 5.0 or higher.
65
67 Upon execution, cyrus-master reads its configuration information out of
68 the cyrus.conf(5) file.
69
70 Cyrus-master rereads its configuration file when it receives a hangup
71 signal, SIGHUP. Services and events may be added, deleted or modified
72 when the configuration file is reread. Any active services removed
73 from the configuration file will be allowed to run until completion.
74
76 The environment variable CYRUS_VERBOSE can be set to log additional
77 debugging information. Setting the value to 1 results in base level
78 logging. Setting it higher results in more log messages being gener‐
79 ated.
