1. The recommended server to sync is windows2003 SP2 above. 2. Make sure that the computers you want to synchronize are joined to the domain and log on to the system using the same domain account (preferably the administrator). The system does not have a firewall turned on. (without joining the domain, please set the password of the computer's Aministrator account to the same password, and add the computer name IP in the Hosts file of each machine to allow them to resolve each other's name) 3.

Mysql master-slave and master-slave ReplicationMysql master-slave and master-slave ReplicationI. Introduction to replicationMySQL supports one-way and asynchronous replication. One server acts as the master server during the replication process, and one or more other serversAct as the slave server. The master server writes updates to the binary log file and maintains an index of the file to track log loops.

You are welcome to visit my personal website: www.deanlinux.com to write only some technical articles. MySQL Master/Slave architecture: In enterprise applications, MySQL often uses a master-slave architecture or a master-master architecture, which can achieve load balancing on the MySQL server and improve the performance of the MySQL server. The key is that Mysql Data Synchroni
Test instructions: A set (matrix) m[i][j]=m[j][i] weight, divided into two sets, so that its weight value is maximum. Note: Weights in the same set can only be counted one.Idea: DFS Assume that all are in the collection 0 Get the collection 1 when you traverse the ID. If the overall weight of the set 0 associated with the ID is to be added, the overall weight value should be reduced If you get a set of 1 weights, go back to

Label:Introduced:In a running database-driven application, SQL replication can solve many problems. Because the Send/subscribe pattern is not very easy to understand, the complex scripting language and the Monitoring replication system also need some thought in it. I hope that in the next few chapters can be as far as possible the basic principles and operations elaborated in detail, easy to understand. In

A replica set (replica sets) is an additional copy of the data that is the process of synchronizing data across multiple servers, which provides redundancy and increases data availability, and enables recovery of hardware failures and outage services through replication sets.

Label:Please refer to MySQL official documentation reference Manual, version 5.6.10. Replication allows data to be copied from one MySQL database (Master Master Library) to another or multiple MySQL databases (slave from the library). By default, replication is asynchronous, and slave does not need to maintain a persistent connection to get updates from master. This means that updates can work on remote con
BFS, breadth First search, one layer to traverse the diagram, it is called breadth first. Implementation method: Queue. DFS, Depth-first search, wall-to-back traversal, called depth first. Implementation method: Recursive (Stack). Both of these traversal methods are the basic way to access the graph. If the comparison of the tree, BFS corresponding to the level of traversal, DFS corresponding to three basic
