mysqld_multi version 2.16 by Jani Tolonen Description: mysqld_multi can be used to start, reload, or stop any number of separate mysqld processes running in different TCP/IP ports and UNIX sockets. mysqld_multi can read group [mysqld_multi] from my.cnf file. You may want to put options mysqld=... and mysqladmin=... there. Since version 2.10 these options can also be given under groups [mysqld#], which gives more control over different versions. One can have the default mysqld and mysqladmin under group [mysqld_multi], but this is not mandatory. Please note that if mysqld or mysqladmin is missing from both [mysqld_multi] and [mysqld#], a group that is tried to be used, mysqld_multi will abort with an error. mysqld_multi will search for groups named [mysqld#] from my.cnf (or the given --defaults-extra-file=...), where '#' can be any positive integer starting from 1. These groups should be the same as the regular [mysqld] group, but with those port, socket and any other options that are to be used with each separate mysqld process. The number in the group name has another function; it can be used for starting, reloading, stopping, or reporting any specific mysqld server. Usage: mysqld_multi [OPTIONS] {start|reload|stop|report} [GNR,GNR,GNR...] or mysqld_multi [OPTIONS] {start|reload|stop|report} [GNR-GNR,GNR,GNR-GNR,...] The GNR means the group number. You can start, reload, stop or report any GNR, or several of them at the same time. (See --example) The GNRs list can be comma separated or a dash combined. The latter means that all the GNRs between GNR1-GNR2 will be affected. Without GNR argument all the groups found will either be started, reloaded, stopped, or reported. Note that syntax for specifying GNRs must appear without spaces. Options: These options must be given before any others: --no-defaults Do not read any defaults file --defaults-file=... Read only this configuration file, do not read the standard system-wide and user-specific files --defaults-extra-file=... Read this configuration file in addition to the standard system-wide and user-specific files Using: --example Give an example of a config file with extra information. --help Print this help and exit. --log=... Log file. Full path to and the name for the log file. NOTE: If the file exists, everything will be appended. Using: --mysqladmin=... mysqladmin binary to be used for a server shutdown. Since version 2.10 this can be given within groups [mysqld#] Using: --mysqld=... mysqld binary to be used. Note that you can give mysqld_safe to this option also. The options are passed to mysqld. Just make sure you have mysqld in your PATH or fix mysqld_safe. Using: Please note: Since mysqld_multi version 2.3 you can also give this option inside groups [mysqld#] in ~/.my.cnf, where '#' stands for an integer (number) of the group in question. This will be recognised as a special option and will not be passed to the mysqld. This will allow one to start different mysqld versions with mysqld_multi. --no-log Print to stdout instead of the log file. By default the log file is turned on. --password=... Password for mysqladmin user. --silent Disable warnings. --tcp-ip Connect to the MySQL server(s) via the TCP/IP port instead of the UNIX socket. This affects stopping and reporting. If a socket file is missing, the server may still be running, but can be accessed only via the TCP/IP port. By default connecting is done via the UNIX socket. --user=... mysqladmin user. Using: root --verbose Be more verbose. --version Print the version number and exit.
