Embodiment Construction

[0010] Combine below Figure 1 to Figure 3 , the present invention is described in further detail.

[0011] refer to figure 1 , a high-availability database cluster method based on invisible watermarks, comprising the following steps: S100, create a PXC container, and the PXC nodes in the PXC container map data directories; Load balancing; S300, using the keepalived service to configure the running status of multiple haproxy containers as follows: one of them is working, and the others are preparing. Using the PXC cluster can ensure that data replication is bidirectional. Data written on any node will be synchronized to other nodes, ensuring strong data consistency; through haproxy for load balancing, requests are evenly distributed to each node , the load of each node is low and the performance is good; at the same time, the use of a single IP for the front-end program through the keepalived service can also ensure that the actual processing machines at the back-end are mul...

Abstract

The invention particularly relates to a high-availability database clustering method based on an invisible watermark, which comprises the following steps: S100, creating a PXC container, and mapping a data directory by a PXC node in the PXC container; S200, using two or more than two haploxy containers to respectively realize load balancing of each PXC node; and S300, using the keepalived service to configure the running states of the plurality of haploxy containers as follows: one of the haploxy containers is working, and the other haploxy containers are prepared. The PXC cluster is used, so that data copying can be ensured to be bidirectional, data is written in any node and can be synchronized to other nodes, and high consistency of the data is ensured; load balancing is carried out through haploxy, requests are uniformly distributed to each node, and each node is low in load and good in performance; meanwhile, through the keepalived service, it is ensured that a front-end program uses a single IP, it can also be ensured that the number of actual processing machines at the rear end is multiple, and the defects of a single-node database are overcome.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a high-availability database cluster method based on an invisible watermark. Background technique [0002] Invisible watermarking is to add information that is imperceptible to the human senses on the file to facilitate the protection of file ownership or embedded information. At present, invisible watermarks are often used in copyright protection and information leakage traceability. Copyright protection, that is, adding an invisible watermark to the image, can prove the copyright ownership of the image for the author or authorized person of the image, and prevent the image from being illegally used without the authorization of the author; prevent information leakage, that is, in the confidential information In the file, different invisible watermarks are applied to different visitors. If the picture is leaked, the source of the leak can be found out by analyzing the invis...
