Redis cluster installation

REDIS-TRIB.RB is a REDIS cluster management tool implemented with Ruby. Internally through cluster related commands to simplify the common operations of cluster creation, inspection, slot migration and equalization

1.ruby Installation
Download Address: wget https://cache.ruby-lang.org/pub/ruby/2.5/ruby-2.5.1.tar.gz

./configure-prefix=/usr/local/ruby Make make Install Cd/usr/local/ruby Cp/usr/local/ruby/bin/ruby/usr/local/bin Cp/usr/local/ruby/bin/gem/usr/local/bin

Download: Https://rubygems.org/downloads/redis-4.0.1.gem

[Root@localhost tools]# gem install-l redis-4.0.1.gem error:loading command:install (loaderror) cannot load such file --zlib error:while executing gem ... (nomethoderror) undefined method ' Invoke_with_build_args ' for Nil:nilclass

The solution is:

Yum-y Install Zlib-devel Enter the ruby source folder to install Ruby itself with the Zlib package CD Ruby-2.5.1/ext/zlib Ruby./extconf.rb [Root@localhost zlib]# make Make: * * * No rule to do target '/include/ruby.h ', needed by ' ZLIB.O '. Stop. This time to open the Ext/zlib/makefile file, find the following line to modify the path. #zlib. O: $ (top_srcdir)/include/ruby.h zlib.o:.. /.. /include/ruby.h

Make make Install
2. Installation

[Root@localhost tools]# Gem install-l redis-4.0.1.gem Gem list--check Redis gem cp/usr/local/redis/src/redis-trib.rb/usr/local/bin/

3. After you install the Ruby environment, execute the REDIS-TRIB.RB command to confirm that it is correct

[Root@localhost src]# redis-trib.rb usage:redis-trib <command> <options> <arguments ...> Create host1 :p ort1 ... hostn:portn--replicas <arg> ...

You can use the REDI-TRIB.RB create command to quickly build a cluster

4. Prepare the node

Configure the configuration file and start

Port 6000 Daemonize Yes LogFile "6000.log" Dir "/data/redis/data/" Dbfilename Dump-6000.rdb cluster-enabled Yes #开启集群模式 cluster-node-timeout 15000 #节点超时时间, unit milliseconds Cluster-config-file "Nodes-6000.conf" #集群内部配置文件

5. Start all Nodes

Redis-server/data/redis/conf/redis-6001.conf Redis-server/data/redis/conf/redis-6002.conf Redis-server/data/redis/conf/redis-6003.conf Redis-server/data/redis/conf/redis-6004.conf Redis-server/data/redis/conf/redis-6005.conf redis-server/data/redis/conf/redis-6006.conf

6. Create a cluster

After starting 6 nodes, the process of using the REDIS-TRIB.RB Create command to complete the handshake and allocate slots

REDIS-TRIB.RB Create--replicas 1 127.0.0.1:6001 127.0.0.1:6002 127.0.0.1:6003 127.0.0.1:6004 127.0.0.1:6005 127.0.0.1:6006
