Setting up redis cluster cluster under Windows

One 、 Download and install

• You need to download the following three ：Redis、Ruby Language environment 、Redis Of Ruby drive redis-3.2.2.gem

• 1、Redis-x64-5.0.14.1.zip download , 6 platform redis The server , Build pseudo clusters , And run on different ports 6380-6385
  

• 2、Ruby download ,ruby Script to build the cluster , All the way next, Finally, uncheck ,finish, then cmd It outputs ruby -v Represents a successful installation
  
  
  

• 3、 install Redis Of Ruby drive rubygems download , It's a tool for Ruby Components are packaged Ruby Packing system ; Decompress after downloading , Then open the command window and switch to the decompression directory , Carry out orders ruby setup.rb
  
  

Two 、 build Redis colony

• For the cluster to function properly, at least 3 Main node , Recommended configuration 3 Main node , rest 3 As the slave nodes of each master node （ It is also the mode recommended by the official website ）, Simulate through different ports of the same computer

• 1、 Create a new folder Redis-cluster, And download the above Redis-x64-5.0.14.1.zip unpack , And rename the folder to 6380
  

• 2、 open 6380 A file in a directory redis.windows.conf, Modify the port number inside port by 6380, The main changes are as follows ,

  1. port 6380 // Change to the same port number as the current folder name 
  2. appendonly yes // Specifies whether to log after each update operation ,Redis stay   By default, data is written to disk asynchronously , If you don't turn it on , It may lead to 4.  Cause data loss for a period of time . yes Express ： storage ,aof, Save the write operation record to the log 
  3. cluster-enabled yes // Turn on cluster mode 
  4. cluster-config-file nodes-6380.conf  // Save node configuration , Automatically create , Auto update ( It is recommended to add port number when naming )
  5. cluster-node-timeout 15000 // Cluster timeout , If the node does not respond after this time, it is determined to be down 
  

  

• 3、 stay 6380 New file in directory start.bat, The contents are as follows , It is used to enter the folder named by each port to start the service

  title redis-6380
  redis-server.exe redis.windows.conf
  

  

• 4、 Copy 6380 Folder , And rename to 6381-6385, At the same time, modify the redis.windows.con And start.bat The port number in the file , take 6380 Replace with the corresponding 6381-6385
  

• 5、 Open any cmd Window execution gem install redis
  

• 6、 Build cluster scripts , from 6380 Copy and paste under the directory redis-cli.exe To Redis-cluster Under the table of contents , meanwhile 6380~6385 Under each directory start.bat Double click the file to run without closing !!!
  
  

• 7、 Then in the present Redis-cluster Open in directory cmd window , Execute the following command , Now the cluster is built

  redis-cli --cluster create 127.0.0.1:6380 127.0.0.1:6381 127.0.0.1:6382 127.0.0.1:6383 127.0.0.1:6384 127.0.0.1:6385 --cluster-replicas 1
  

  

3、 ... and 、 Cluster environment test

• Reference documents
• redis-cli -c -h 127.0.0.1 -p 6380
• View cluster information ：cluster info
• View master-slave relationship ：info replication, Cluster nodes are arranged from left to right from master to slave 6 individual redis node , So it can also be seen that 6380,6381,6382 Three are the master nodes ,6383,6384,6385 There are three slave nodes , The correspondence is ： Lord 6380 from 6383
• View the node assignments slot：cluster nodes
  

Four 、 take redis-cluster Registered student windows service

• Reference documents

• Console launch redis server If the console is closed redis server Will be shut down together , Then we need to let redis Running in the background requires redis server register as windows service , And then again start

• So we can solve the above problems in the following ways , To 6380-6385 Rename services respectively under the directory , And start the , Please ensure that at least three master node services have been started in the background , Otherwise, it will cause the connection redis-cluster, But it can't connect to the inside db0

  #  adopt service-name start-up redis service ：
  redis-server --service-install redis.windows.conf --service-name redis6380 --loglevel verbose
  redis-server --service-start --service-name redis6380
  
  #  adopt service-name stop it redis service ：
  redis-server --service-stop --service-name redis6380
  

  
  

• If the service fails to start , Open as administrator cmd perform SC delete The service name , Then when the corresponding directory is rebuilt
  

5、 ... and 、 open redis Visualization tools , The connection is successful as shown in the figure

• Pictured , Test connection successful
  
• The default is 127.0.0.1 You can visit , Modified as follows .conf, You can modify bind Designated LAN ip visit , After modifying the configuration , You need to restart the service to take effect
