Bootstrap Router
Bootstrap Router
mysqlrouter --bootstrap root@localhost:3310 --user=root --directory /mysql/myrouter
# Bootstrapping MySQL Router instance at '/mysql/myrouter'...
- Creating account(s) (only those that are needed, if any)- Verifying account (using it to run SQL queries that would be run by Router)- Storing account in keyring- Adjusting permissions of generated files- Creating configuration /mysql/myrouter/mysqlrouter.conf
# MySQL Router configured for the InnoDB Cluster 'myCluster'
After this MySQL Router has been started with the generated configuration
$ mysqlrouter -c /mysql/myrouter/mysqlrouter.conf
the cluster 'myCluster' can be reached by connecting to:
## MySQL Classic protocol
- Read/Write Connections: localhost:6446- Read/Only Connections: localhost:6447
## MySQL X protocol
- Read/Write Connections: localhost:6448- Read/Only Connections: localhost:6449
cd /mysql/myrouter
./start.sh
