Error 1076 ER_READY is an informational MySQL server line that announces the daemon is fully started and ready to accept client connections.
MySQL Error 1076: ER_READY is a startup notice that the mysqld process is “ready for connections.” No immediate fix is required. If the line is missing or followed by crashes, verify the port, socket path, and service status, then restart MySQL to restore normal operation.
%s: ready for connections. Version: '%s' socket: '%s'
MySQL prints Error 1076 with the symbolic name ER_READY during server startup. The complete text is usually “mysqld: ready for connections. Version: '8.0.x' socket: '/tmp/mysql.sock' port: 3306.” The word “Error” is historical; the line is a normal informational message, not a fault.
The notice confirms that configuration parsing, storage-engine initialization, redo-log recovery, and listener creation have completed.
From this point forward, clients can connect through TCP or the Unix socket.
ER_READY is the final step of the bootstrap sequence. You will see it in the MySQL error log, journald, Docker container stdout, or Kubernetes pod logs. Automated health-checks often wait for this exact line to decide that the database is alive.
If the daemon exits before printing ER_READY, startup failed.
Checking how long it takes for the line to appear helps operators detect hangs or configuration mistakes.
Legacy MySQL code labels many server messages with an error code, even when the content is purely informational. ER_READY therefore uses the 1xxx numeric range reserved for server messages, but its severity is “Note.” Monitoring tools should whitelist or downgrade this line.
Applications never receive ER_READY directly. They only experience connection failures when the line is absent.
Recognising ER_READY in logs allows developers to separate genuine connection errors from normal startup chatter.
Galaxy’s connection tester watches the MySQL error log for ER_READY before issuing user queries. This prevents “can’t connect” errors in the editor and shortens debugging time for developers.
.
The most common “cause” is simply that mysqld finished booting and is advertising its readiness.
Administrators sometimes misread the message when the printed port or socket differs from expectations, mistakenly treating it as an error.
Alerting systems that flag any line containing the word “Error” may raise an incident even though ER_READY is benign.
If ER_READY appears repeatedly in a short span, the server may be crashing and auto-restarting, indicating a deeper configuration or resource issue.
.
No. Despite its label, Error 1076 ER_READY is a note-level message meaning the server is ready to accept connections.
If ER_READY appears once per startup and the server stays running, nothing needs fixing. Repeated appearances may indicate a crash loop.
Many log parsers flag any “Error” substring. Whitelist code 1076 or filter by severity “Note” to suppress false positives.
Yes. Galaxy waits for ER_READY before executing queries and surfaces detailed log output when the server fails to reach that stage.
