register-node
Description
Register an existing node on the host.
Usage
Register an existing node on the host
Usage:
memsqlctl register-node [flags]
Flags:
--auditlogsdir DIRECTORY_PATH Path to the auditlogs directory
--datadir DIRECTORY_PATH Path to the data directory
--force Skip safety checks that require the node be online (e.g., the password is correct). Use this flag to register an offline node
-h, --help Help for register-node
--memsql-config FILE_PATH Path to the node config file
--password STRING The current database root password
--pid-file FILE_PATH Path to the current pid file
--plancachedir DIRECTORY_PATH Path to the plancache directory
-P, --port PORT The current port
--ssl-fips-mode string Whether the node operates in OpenSSL/FIPS mode
--tracelogsdir DIRECTORY_PATH Path to the tracelogs directory
Global Flags:
-c, --config FILE_PATH Path to the memsqctl config file
--default-install-dir DIRECTORY_PATH Path to the default install directory
--insecure-ssl Fall back to insecure SSL connections to local SingleStoreDB nodes if memsqlctl is unable to otherwise establish a connection (ADVANCED)
-j, --json Print output in JSON format
--node-metadata-file FILE_PATH Path to the node metadata file
--parallelism POSITIVE_INTEGER Maximum amount of operations to be run in parallel
--ssl-ca FILE_PATH The path to the CA certificate file (in PEM format) to authenticate the database certificate
--timeout duration Maximum time for operation to complete (e.g., 30s, 10m, 1.5h)
--verbose-json Print output in JSON format, include some warnings and user messages
-v, --verbosity count Increase logging verbosity
-y, --yes Enable non-interactive mode and assume the user would like to move forward with the proposed actions by default
Remarks
The path to the node’s
memsql.cnf
file must be passed into the--memsql-config
flag. The default location for this file is at/var/lib/memsql/<UUID>/memsql.cnf
on the host machine. Also, theauditlogs
,data
,tracelogs
, andplancache
directories specified inmemsql.cnf
must be owned by the SingleStoreDB user for that node. The default owner:group for each node ismemsql:memsql
.The
register-node
command also assumes the node is online. If you are trying to register a node that is offline, you must specify--force
when running this command. Note: This will cause memsqlctl to skip safety checks that require the node to be online (e.g., password is correct).--password
is a required flag that specifies the SingleStoreDBroot
password for the node being registered. You can optionally use this flag in conjunction with the--user
flag to specify a SingleStoreDB user that is different from theroot
user and the user’s password. Note that theMEMSQL_PASSWORD
environment variable is a safer alternative option for setting the password.Wrap the password string in single quotes (') to avoid having the shell try to interpret any special characters included in the string.
This command is interactive unless you use either
--yes
or--json
flag to override interactive behavior.The
memsqlctl register-node
command is equivalent to the sdb-admin register-node command.
Output
The following example shows how to register an existing node with a different memsql.cnf
file.
$ sudo memsqlctl register-node --memsql-config /tmp/memsql.cnf memsqlctl will perform the following actions: · Register node on port 3308 - Config file = /tmp/memsql.cnf + datadir = /tmp/data + plancachedir = /tmp/plancache + tracelogsdir = /tmp/tracelogs + auditlogsdir = /tmp/auditlogs Would you like to continue?
