Database mode switching method and device and electronic equipment

Abstract

The invention provides a database mode switching method and device and electronic equipment, and the method comprises the following steps: receiving a mode switching instruction, and checking whetheran installation package of database management software is written into a new node or not based on the address of the new node in the mode switching instruction; if yes, stopping the write-in serviceof the database, and exporting the database to a local specified directory; if the database is successfully exported, installing the database management software on the new node based on the installation package, and updating the configuration of the database management software of the new node and the configuration of the database management software of the new node according to a preset high-availability strategy; and importing the database into the new node, and starting write-in services of the database and the new node. According to the technical scheme, switching of the database from thesingle-machine mode to the double-machine mode is achieved, and therefore disaster recovery and high availability of the database are achieved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a database mode switching method, device and electronic equipment. Background technique [0002] The database installation modes are mainly divided into three categories: one is stand-alone mode, which only installs the database environment on a single device. This mode is low in cost and easy to install and deploy, and is suitable for small projects; The databases are installed on the devices separately, and the databases of the two devices are configured as a high-availability dual-machine cluster (High Available, HA). The two devices in the dual-machine cluster can synchronize the data of their own databases to the database of the peer device in real time. In order to achieve high availability; the third is the cluster mode, install the database on at least three devices, and the database on each device forms a distributed storage. The cluster mode has strong high ...

[0002] The database installation modes are mainly divided into three categories: one is stand-alone mode, which only installs the database environment on a single device. This mode is low in cost and easy to install and deploy, and is suitable for small projects; The databases are installed on the devices separately, and the databases of the two devices are configured as a high-availability dual-machine cluster (High Available, HA). The two devices in the dual-machine cluster can synchronize the data of their own databases to the database of the peer device in real time. In order to achieve high availability; the third is the cluster mode, install the database on at least three devices, and the database on each device forms a distributed storage. The cluster mode has high availability, but the cost is high, and it is suitable for large-scale projects

[0003] With the development of the project, the amount of data it contains will continue to increase. If the stand-alone model is always used to store data, the normal operation of the business may be affected due to network instability or equipment downtime, and even lead to data loss or business interruption
