Foreword:
Clustering refers to providing the same service by adding the number of servers, so as to achieve a stable and efficient state. Why use redis cluster? The redis cluster can enhance the reading and writing capabilities of redis.
Now let’s formally learn about redis cluster.
Preparation work:
Requires 4 components: Redis, Ruby language runtime environment, Redis Ruby driver redis-xxxx.gem, and the tool to create a Redis cluster redis-trib.rb. Use the redis-trib.rb tool to create a Redis cluster. Since this file is written in ruby language, you need to install the Ruby development environment and drive redis-xxxx.gem.
1) Download the Redis installation file: https://github.com/MSOpenTech/redis/releases/, Redis provides download files in msi and zip formats, download zip here Format Redis-x64-3.2.100 version.
2) Download the Ruby installation file: http://dl.bintray.com/oneclick/rubyinstaller/rubyinstaller-2.2.4-x64.exe
3) Download Redis in the Ruby environment Driver: https://rubygems.org/gems/redis/versions/3.2.2. Considering compatibility, the 3.2.2 version is downloaded here.
Note: Download the related link in the lower right corner of the page.中
4) Download the ruby script file redis-trib.rb officially provided by Redis to create a Redis cluster. The path is as follows: https://raw.githubusercontent.com/MSOpenTech /redis/3.0/src/redis-trib.rb
Install Redis
Just decompress the downloaded Redis-x64-3.2.100.zip. For ease of use, it is recommended to put it in In the root directory of the drive letter, such as: D:\Redis-Cluster\Redis-x64-3.2.100.
Install Redis and run 3 instances (Redis cluster requires at least 3 nodes, less than 3 cannot be created);
Start 6 different Redis instances through configuration files, Since the default port of Redis is 6379, 6380, 6381, 6382, 6383, 6384, and 6385 are used here to run 6 Redis instances.
Note:
(1) In order to avoid unnecessary errors, try to save the configuration file in utf8 format and do not include comments;
(2) The following in the configuration file There are two ways to save logs (save in files and save in System Log). Please choose one according to your needs:
loglevel notice #日志的记录级别,notice是适合生产环境的 logfile "D:/Redis-Cluster/Redis-x64-3.2.100/Logs/redis6380_log.txt" #指定log的保持路径,默认是创建在Redis安装目录下,如果有子目录需要手动创建,如此处的Logs目录 syslog-enabled yes #是否使用系统日志 syslog-ident redis6380 #在系统日志的标识名
The method of saving in files is used here, so first save in the Redis directory Create a new Logs folder under D:\Redis-Cluster\Redis-x64-3.2.100.
In the root directory of the Redis installation, create configuration files with encoding format utf-8: redis.6380.conf, redis.6381.conf, redis.6382.conf, redis.6383.conf, redis. 6384.conf, redis.6385.conf.
redis.6380.conf、
port 6380 loglevel notice logfile "D:/Redis-Cluster/Redis-x64-3.2.100/Logs/redis6380_log.txt" appendonly yes appendfilename "appendonly.6380.aof" cluster-enabled yes cluster-config-file nodes.6380.conf cluster-node-timeout 15000 cluster-slave-validity-factor 10 cluster-migration-barrier 1 cluster-require-full-coverage yes
redis.6381.conf、
port 6381 loglevel notice logfile "D:/Redis-Cluster/Redis-x64-3.2.100/Logs/redis6381_log.txt" appendonly yes appendfilename "appendonly.6381.aof" cluster-enabled yes cluster-config-file nodes.6381.conf cluster-node-timeout 15000 cluster-slave-validity-factor 10 cluster-migration-barrier 1 cluster-require-full-coverage yes
redis.6382.conf、
port 6382 loglevel notice logfile "D:/Redis-Cluster/Redis-x64-3.2.100/Logs/redis6382_log.txt" appendonly yes appendfilename "appendonly.6382.aof" cluster-enabled yes cluster-config-file nodes.6382.conf cluster-node-timeout 15000 cluster-slave-validity-factor 10 cluster-migration-barrier 1 cluster-require-full-coverage yes
redis.6383.conf、
port 6383 loglevel notice logfile "D:/Redis-Cluster/Redis-x64-3.2.100/Logs/redis6383_log.txt" appendonly yes appendfilename "appendonly.6383.aof" cluster-enabled yes cluster-config-file nodes.6383.conf cluster-node-timeout 15000 cluster-slave-validity-factor 10 cluster-migration-barrier 1 cluster-require-full-coverage yes
redis.6384.conf、
port 6384 loglevel notice logfile "D:/Redis-Cluster/Redis-x64-3.2.100/Logs/redis6384_log.txt" appendonly yes appendfilename "appendonly.6384.aof" cluster-enabled yes cluster-config-file nodes.6384.conf cluster-node-timeout 15000 cluster-slave-validity-factor 10 cluster-migration-barrier 1 cluster-require-full-coverage yes

The configuration is explained as follows:
port 6380 #端口号 loglevel notice #日志的记录级别,notice是适合生产环境的 logfile "Logs/redis6380_log.txt" #指定log的保持路径,默认是创建在Redis安装目录下,如果有子目录需要手动创建,如此处的Logs目录 syslog-enabled yes #是否使用系统日志 syslog-ident redis6380 #在系统日志的标识名 appendonly yes #数据的保存为aof格式 appendfilename "appendonly.6380.aof" #数据保存文件 cluster-enabled yes #是否开启集群 cluster-config-file nodes.6380.conf cluster-node-timeout 15000 cluster-slave-validity-factor 10 cluster-migration-barrier 1 cluster-require-full-coverage yes
Save the above configuration files to the Redis directory, and use these configuration files to install 6 A redis service, the command is as follows:
D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-install D:/Redis-Cluster/Redis-x64-3.2.100/redis.6380.conf --service-name redis6380 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-install D:/Redis-Cluster/Redis-x64-3.2.100/redis.6381.conf --service-name redis6381 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-install D:/Redis-Cluster/Redis-x64-3.2.100/redis.6382.conf --service-name redis6382 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-install D:/Redis-Cluster/Redis-x64-3.2.100/redis.6383.conf --service-name redis6383 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-install D:/Redis-Cluster/Redis-x64-3.2.100/redis.6384.conf --service-name redis6384 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-install D:/Redis-Cluster/Redis-x64-3.2.100/redis.6385.conf --service-name redis6385
Note:
1) It is best to use the full path for configuration files such as redis.6380.conf to avoid problems when restarting the Redis cluster
2) The uninstall command is:
D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-uninstall D:/Redis-Cluster/Redis-x64-3.2.100/redis.6380.conf --service-name redis6380 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-uninstall D:/Redis-Cluster/Redis-x64-3.2.100/redis.6381.conf --service-name redis6381 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-uninstall D:/Redis-Cluster/Redis-x64-3.2.100/redis.6382.conf --service-name redis6382 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-uninstall D:/Redis-Cluster/Redis-x64-3.2.100/redis.6383.conf --service-name redis6383 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-uninstall D:/Redis-Cluster/Redis-x64-3.2.100/redis.6384.conf --service-name redis6384 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-uninstall D:/Redis-Cluster/Redis-x64-3.2.100/redis.6385.conf --service-name redis6385
Start these 6 services. The command is as follows:
D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6380 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6381 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6382 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6383 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6384 D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6385
Execution result:
##Install ruby(1) Ruby environment installation. Double-click the downloaded "rubyinstaller-2.2.4-x64.exe" to install it. Similarly, for ease of operation, it is recommended to install it in the root directory of the drive letter, such as: C:\Ruby22-x64, install When you select the last two options here, means adding ruby to the system's environment variables, and you can use ruby commands directly in the cmd command(1) Install the Redis driver in the Ruby environment Copy the downloaded "Redis driver file in the Ruby environment (redis-3.2.2.gem)" to the Ruby installation root directory (C:\Ruby22- x64). Then execute the installation command as follows:gem install --local path_to_gem/filename.gem
