replica beats

MongoDB's replica set mode has been greatly improved by the earlier Master-slave mode, since the previous Master-slave mode does not support the host outage after switching to the slave, has gradually been eliminated. And now the official recommendation of the replica set mode, support multiple nodes coexist, when the main node down from the highest weight of the sub-node, switch to the main node, is very e

Tags: MongoDB replica set frame1, Replication IntroductionMongoDB replication is the replication of data in multiple servers, the purpose of data replication is to provide redundancy and improve the availability of data, the operation of data replication on different database servers to save multiple copies of the data set, so as to avoid single-machine failure and thus loss of data, The replication mechanism also allows you to recover hardware failur

This is always going back and forth through the issi without stopping installation. Every time you start the system, you will be bored. Today I really want to clean him up, so I studied the issi detection method. I thought it would be fine to delete the configuration of notes local mail replica prepare V1.0 in sdword/issimon. ini, but it does not work; Then observe that after the issi scans the results, before you click "Install", several special fi

Label:Recently, the company on the project security issues are very important, conducted a number of various security loopholes scanned, and then swept to the MongoDB weak password problem. At the beginning of the project deployment, because everyone is not special attention to this, presumably because it is the intranet project, so MongoDB database user name and password are admin. This time after sweeping the weak password, asked to solve the problem, so the task was divided on my head. Fol

when setting up a MongoDB replica set, the primary node, the second node, the quorum node, and possibly the resource configuration (CPU or memory) are unbalanced, so it is required that some nodes cannot be primaryWe know the settings of MongoDB:In addition to the quorum node, each of the other nodes has a priority, which can be set manually to determine who has the most weight to become a primay.In a replica
