After reading the mongodb authoritative guide, it is more appropriate to use the replica set for read/write splitting, and the general system is enough to use it. It is easy to find. If you do not describe it, you can only describe the key steps. The two servers are 201 and 202 nodes, the two are initially configured on 202, and the other is added on 201. Deploy two nodes first202:./Mongod -- dbpath./db1 -- port 10002 -- replSet blort/Server202: 10001

How to fix the standby database after ORACLE 11G replica uard Failover, and restore uardfailoverProblem scenarios after failover:Due to the failover test, a standby database has been changed to the primary database. How can I change this new primary database (the original standby database) back to the standby database?Both are primary, p1, and p2. How can I set one primary database 1 to p1, And the other primary database p2 to the p1 standby database?

Does PHP support MongoDB replica set connections?

Previously there was a replica set to build mongodb3.0, but the admin database that was used directly was the root of the user. Links: http://blog.csdn.net/tuzongxun/article/details/51723259 Recently you want to move data to a non-admin database, and then re-create the user in the non-admin library, the process is roughly the same as before, but there are some problems when creating the user, mainly on the user roles and permissions. I built the proce

By default: The primary node is responsible for data read and write, the secondary node backs up the data on the primary node, but the arbiter nodeData is not synchronized from the primary nodeArbiter Effect:When the primary node fails, it can select a primary node from the second node and will not participate in the data read and write.MongoDB uses oplog.rs to synchronize data sets between replication sets.This article is from the DBA Sky blog, so be sure to keep this source http://9425473.blog

Overview You can use a single data server as a shard or a replica set as a shard. The replica set is a master-slave cluster with the automatic fault recovery function, and its master-slave role can be changed automatically. Each replica set includes three roles: master server, slave server, and arbitration server. Deployment Diagram Deployment process

Based on the "Mongodb cluster configuration (sharding with replica set)" cluster (SEE), try to dynamically Add a shard replica set when the Mongodb cluster is running. (1) Start the replica set Node Run the following three batch files to start three Mongod processes: 127.0.0.1: 36000, 127.0.0.1: 36001, and 127.0.0.1: 36002. Batch File startShardD_0.bat: Cd d:/mon
