Procedure for configuring MySQL Database Synchronization

The following article describes how to configure MySQL Database Synchronization. In this experiment, we operate MySQL database 4.1.7-standard-log, the actual operating system on the master side is redhat9.0, and the operating system on the slave side is redhat7.3.1. modify my on the master side. cnf: Add configuration parameters.

The following article describes how to configure MySQL Database Synchronization. In this experiment, we operate MySQL database 4.1.7-standard-log, the actual operating system on the master side is redhat 9.0, and the operating system on the slave side is redhat 7.3.

1. modify my. cnf on the master end and add the configuration parameters:

 
 

  
  
[MySQL (the best combination with PHP) d]
  
  
Log-bin
  
  
Server-id = 1
 
 

2. modify my. cnf on the slave side and add the configuration parameters:

 
 

  
  
log-bin 
  
  
mastermaster-host=master 
  
  
master-user=rep 
  
  
master-password=rep 
  
  
master-port=3306 
  
  
server-id=2 
 
 

The above parameters are the most basic configuration, so I will not explain them much. I will undo it to initialize the data.

1. Clear all binlogs on the master. If the existing binlogs are useful, back up them first. Then, pack all data files on the master, including ibdata files.

2. A similar method is used to clear all binlogs on the slave and copy the data file compressed package on the master to its own data file directory.

Start master and add a rep user

 
 

  
  
,"grant all privileges on *.* to rep@% identified by 'rep'; flush privileges; ". 
 
 

Start slave and check whether MySQL Database Synchronization is successful.

Generally, the reason for the failure is that the binlog fails to be located after the slave connects to the master. Therefore, you need to set the binlogs of both parties to be consistent, and then stop slave; start slave.
