You can also start Manticore Search by calling searchd (Manticore Search server binary) directly:
searchd [OPTIONS]Note that without specifying a path to the configuration file, searchd will try to find it in several locations depending on the operating system.
The options available to searchd in all operation systems are:
--help (-h for short) lists all of the parameters that can be used in your particular build ofsearchd.--version (-v for short) shows Manticore Search version information.--config <file> (-c <file> for short) tells searchd to use the specified file as its configuration.--stop is used to asynchronously stop searchd, using the details of the PID file as specified in the Manticore configuration file. Therefore, you may also need to confirm to searchd which configuration file to use with the --config option. Example:$ searchd --config /etc/manticoresearch/manticore.conf --stop--stopwait is used to synchronously stop searchd. --stop essentially tells the running instance to exit (by sending it a SIGTERM) and then immediately returns. --stopwait will also attempt to wait until the running searchd instance actually finishes the shutdown (eg. saves all the pending attribute changes) and exits. Example:$ searchd --config /etc/manticoresearch/manticore.conf --stopwaitPossible exit codes are as follows:
0 on success
1 if connection to running searchd server failed
2 if server reported an error during shutdown
3 if server crashed during shutdown
--status command is used to query running searchd instance status using the connection details from the (optionally) provided configuration file. It will try to connect to running instance using the first found UNIX socket or TCP port from the configuration file. On success it will query for a number of status and performance counter values and print them. You can also use SHOW STATUS command to access the very same counters via SQL protocol. Examples:
$ searchd --status
$ searchd --config /etc/manticoresearch/manticore.conf --status--pidfile is used to explicitly force using a PID file (where the searchd process identification number is stored) despite any other debugging options that say otherwise (for instance, --console). This is a debugging option.$ searchd --console --pidfile--console is used to force searchd into console mode. Typically, Manticore runs as a conventional server application and logs information into log files (as specified in the configuration file). However, when debugging issues in the configuration or the server itself, or trying to diagnose hard-to-track-down problems, it may be easier to force it to dump information directly to the console/command line from which it is being called. Running in console mode also means that the process will not be forked (so searches are done in sequence) and logs will not be written to. (It should be noted that console mode is not the intended method for running searchd.) You can invoke it as:$ searchd --config /etc/manticoresearch/manticore.conf --console--logdebug, --logreplication, --logdebugv, and --logdebugvv options enable additional debug output in the server log. They differ by the logging verboseness level. These are debugging options and should not be normally enabled, as they can pollute the log a lot. They can be used temporarily on request to assist with complicated debugging sessions.--iostats is used in conjunction with the logging options (the query_log must have been activated in manticore.conf) to provide more detailed information on a per-query basis about the input/output operations carried out in the course of that query, with a slight performance hit and slightly bigger logs. The IO statistics don’t include information about IO operations for attributes, as these are loaded with mmap. To enable it, you can start searchd as follows:$ searchd --config /etc/manticoresearch/manticore.conf --iostats--cpustats is used to provide actual CPU time report (in addition to wall time) in both query log file (for every given query) and status report (aggregated). It depends on clock_gettime() Linux system call or falls back to less precise call on certain systems. You might start searchd thus:$ searchd --config /etc/manticoresearch/manticore.conf --cpustats--port portnumber (-p for short) is used to specify the port that Manticore should listen on to accept binary protocol requests, usually for debugging purposes. This will usually default to 9312, but sometimes you need to run it on a different port. Specifying it on the command line will override anything specified in the configuration file. The valid range is 0 to 65535, but ports numbered 1024 and below usually require a privileged account in order to run. An example of usage: bash $ searchd --port 9313--listen ( address ":" port | port | path ) [ ":" protocol ] (or -l for short) Works as --port, but allows you to specify not only the port, but the full path, IP address and port, or Unix-domain socket path that searchd will listen on. In other words, you can specify either an IP address (or hostname) and port number, just a port number, or a Unix socket path. If you specify a port number but not the address, searchd will listen on all network interfaces. A Unix path is identified by a leading slash. As the last parameter, you can also specify a protocol handler (listener) to be used for connections on this socket. Supported protocol values are ‘sphinx’ and ‘mysql’ (MySQL protocol used since 4.1).--force-preread forbids the server from serving any incoming connection until prereading of table files completes. By default, at startup, the server accepts connections while table files are lazy-loaded into memory. This extends the behavior and makes it wait until the files are loaded.--index (--table) <table> (or -i (-t) <table> for short) forces this instance of searchd to only serve the specified table. Like --port, above, this is usually for debugging purposes; more long-term changes would generally be applied to the configuration file itself.--strip-path strips the path names from all the file names referenced from the table (stopwords, wordforms, exceptions, etc). This is useful for picking up tables built on another machine with possibly different path layouts.--replay-flags=<OPTIONS> switch can be used to specify a list of extra binary log replay options. The supported options are:
accept-desc-timestamp, ignore descending transaction timestamps and replay such transactions anyway (the default behavior is to exit with an error).ignore-open-errors, ignore missing binlog files (the default behavior is to exit with an error).ignore-trx-errors, ignore any transaction errors and skip current binlog file (the default behavior is to exit with an error).ignore-all-errors, ignore any errors described above (the default behavior is to exit with an error). Example:$ searchd --replay-flags=accept-desc-timestamp--coredump is used to enable saving a core file or a minidump of the server on crash. Disabled by default to speed up of server restart on crash. This is useful for debugging purposes.$ searchd --config /etc/manticoresearch/manticore.conf --coredump--new-cluster bootstraps a replication cluster and makes the server a reference node with cluster restart protection. On Linux you can also run manticore_new_cluster. It will start Manticore in --new-cluster mode via systemd.--new-cluster-force bootstraps a replication cluster and makes the server a reference node bypassing cluster restart protection. On Linux you can also run manticore_new_cluster --force. It will start Manticore in --new-cluster-force mode via systemd.There are some options for searchd that are specific to Windows platforms, concerning handling as a service, and are only available in Windows binaries.
Note that in Windows searchd will default to --console mode, unless you install it as a service. * --install installs searchd as a service into the Microsoft Management Console (Control Panel / Administrative Tools / Services). Any other parameters specified on the command line, where --install is specified will also become part of the command line on future starts of the service. For example, as a part of calling searchd, you will likely also need to specify the configuration file with --config, and you would do that as well as specifying --install. Once called, the usual start/stop facilities will become available via the management console, so any methods you could use for starting, stopping and restarting services would also apply to searchd. Example:
C:\WINDOWS\system32> C:\Manticore\bin\searchd.exe --install
--config C:\Manticore\manticore.confIf you want to have the I/O stats every time you start searchd, you need to specify the option on the same line as the --install command thus:
C:\WINDOWS\system32> C:\Manticore\bin\searchd.exe --install
--config C:\Manticore\manticore.conf --iostats--delete removes the service from the Microsoft Management Console and other places where services are registered, after previously being installed with --install. Note that this does not uninstall the software or delete the tables. It means the service will not be called from the services system, and will not be started on the machine’s next start. If currently running as a service, the current instance will not be terminated (until the next reboot or until --stop). If the service was installed with a custom name (with --servicename), the same name will need to be specified with --servicename when calling to uninstall. Example:C:\WINDOWS\system32> C:\Manticore\bin\searchd.exe --delete--servicename <name> applies the given name to searchd when installing or deleting the service, as it would appear in the Management Console; this will default to searchd, but if being deployed on servers where multiple administrators may log in to the system, or a system with multiple searchd instances, a more descriptive name may be applicable. Note that unless combined with --install or --delete, this option does not do anything. Example:C:\WINDOWS\system32> C:\Manticore\bin\searchd.exe --install
--config C:\Manticore\manticore.conf --servicename ManticoreSearch--ntservice is an option that is passed by the Microsoft Management Console to searchd to invoke it as a service on Windows platforms. It would not normally be necessary to call this directly; this would normally be called by Windows when the service is started, although if you wanted to call this as a regular service from the command-line (as the complement to --console) you could do so in theory.--safetrace forces searchd to only use the system’s backtrace() call in crash reports. In certain (rare) scenarios, this might be a “safer” way to get that report. This is a debugging option.--nodetach switch (Linux only) tells searchd not to detach into the background. This will also cause log entries to be printed out to the console. Query processing operates as usual. This is a debugging option and might also be useful when you run Manticore in a Docker container to capture its output.Manticore utilizes the plugin_dir for storing and using Manticore Buddy plugins. By default, this value is accessible to the “manticore” user in a standard installation. However, if you start the searchd daemon manually with a different user, the daemon might not have access to the plugin_dir. To address this problem, ensure you specify a plugin_dir in the common section that the user running the searchd daemon can write to.
searchd supports a number of signals:
MANTICORE_TRACK_DAEMON_SHUTDOWN=1 enables detailed logging while searchd is shutting down. It’s useful in case of some shutdown problems, such as when Manticore takes too long to shut down or freezes during the shutdown process.
