basic master slave relationship

1. IntroductionMaster-slave replication is the most common way to replicate MongoDB. This method is very flexible and can be used for backup, failure recovery, read scaling, and so on.The most basic way to set up is to establish a master node and one or more slave nodes, each from the node to know the address of the

appropriate for the initial configuration at deployment time. 1.3.2 settings in the Redis client This is illustrated by the Jedis, the official Redis recommendation, which is also based on Jedis. Here the Jedis object instance belongs to slave, and the parameter is the address and port of the server. Java code Slavejdedis.slaveof ("10.1.1.102", 6379); #指定master的ip和端口 Slavejdedis.slaveofnoone (); #取消指定

possible. Because the entire replication process is actually a variety of operations that are logged in the execution log that slave obtains the log from the master side and then executes it in its own full sequence. Open MySQL Binary Log by using the "-log-bin" parameter option in the process of starting MySQL Server, or by adding the "Log-bin" parameter to the MYSQLD parameter group in the F configuratio

the following ways:(1) Cool copy (Cold copy)Stop master, copy Master's files to slave, and restart master. The disadvantage is obvious.(2) Hot copy (warm copy)If you use only the MyISAM table, you can use the mysqlhotcopy copy even if the server is running.(3) using mysqldumpUsing mysqldump to get a snapshot of a data can be divided into the following steps:Mysq

I read the Master-Slave settings of MySQL after work in the company. The general meaning and process have been understood, but I have never practiced it. I have time to practice it today. I have two Win7 servers on hand. Let's use them together !! First set the relationship A to Master, B to
