How to achieve efficient data replication and backup in MEMSQL

How to achieve efficient data replication and backup in MEMSQL MEMSQL is a horizontal expanded memory database that provides efficient data replication and backup function to ensure the reliability and persistence of data.This article will introduce how to achieve efficient data replication and backup in MEMSQL, and contain necessary programming code and related configuration. 1. Configure the main database First, configure data copy in the main database.Open the main configuration file of the MEMSQL main database (usually Memsql.cnf or Memsql.conf), and ensure that the following settings have been enabled: memsql_id = master memsql_role = master streaming_Master_Addresses = '<IP_ Address_1>: <Outlet _ number>, <IP_An address_2>: Among them, `IP_An address _1>` and `` IP_ Address_2> `is the IP address of the backup database server. 2. Configure backup database Next, configure the data to copy in the backup database.Open the main configuration file of the MEMSQL backup database, and make sure that the following settings have been enabled: memsql_id = slave memsql_role = slave streaming_Master_Addresses = '<IP_ Address_1>: <Outlet _ number>, <IP_An address_2>: Please ensure that `IP_ Address _1>` and `<IP_ Address_2>` is the IP address of the main database server. 3. Start the main database and backup database After the configuration is completed, start the main database and backup database.In the command line, run the following commands separately: memsql-ops memsql-start --all --memsql-id=master memsql-ops memsql-start --all --memsql-id=slave This will start two databases and let it start copying the data. 4. Monitor data copy You can use the MEMSQL OPS console or MEMSQL Studio to monitor the state of data replication.These tools provide a graphical interface to display the data replication progress and delay of the data between the main database and the backup database. 5. Data backup strategy In addition to data replication, data backup strategies should also be implemented to ensure that data can be recovered when accident failure or disaster occurs.You can use the backup and recovery tools provided by MEMSQL to perform regular data backup. # Create backup memsql-ops backup create --all-databases --backup-type=full # View backup list memsql-ops backup list # Restore backup MEMSQL-OPS BACKUP RESTORE-BACKUP-Id = <Backup_ Number> The above commands will create a complete database and store it in the system default.You can check the backup status by checking the backup list, and use the backup number to perform the recovery operation. In summary, by configuring the data replication and backup function of MEMSQL, you can achieve efficient and reliable data replication and backup.At the same time, by monitoring data replication status and regular data backup, the availability and persistence of data can be ensured.
