How to build a redis cluster under windows

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.

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

Create Redis cluster

Put the downloaded ruby ​​script file redis- trib.rb" file to the Redis installation root directory (D:\Redis-Cluster\Redis-x64-3.2.100).

(1) Use redis-trib.rb to create a Redis cluster

Switch to the Redis directory under MD (D:\Redis-Cluster\Redis-x64-3.2.100)

Remarks:

（1）--replicas #指定集群中每个主节点配备几个从节点，这里设置为1。

（2）redis-trib.rb工具的使用

、create：创建集群
、check：检查集群
、info：查看集群信息
、fix：修复集群
、reshard：在线迁移slot
、rebalance：平衡集群节点slot数量
、add-node：将新节点加入集群
、del-node：从集群中删除节点
、set-timeout：设置集群节点间心跳连接的超时时间
、call：在集群全部节点上执行命令
、import：将外部redis数据导入集群

（2）检验是否真的创建成功

输入以下命令：

redis-trib.rb check 127.0.0.1:6380

如果现实信息如下，则说明创建的Redis集群是没问题。
