redis:redis cluster集群主从方案

Redis的安装以及cluster配置

下载redis最新的安装包
wget http://download.redis.io/releases/redis-3.0.7.tar.gz
解压
tar xzf redis-3.0.7.tar.gz 
安装支持包tcl
yum install tcl 编译原文件
make
创建集群相关文件（方便管理）
mkdir cluster 
cd cluster
mkdir 6379 6380 6381 6382 6383 6384 
cluster下面每个目录中都创建一个redis.conf文件. 注意修改文件中的端口号：

port 6379
cluster-enabled yes
cluster-config-file nodes_6379.conf
cluster-node-timeout 5000
appendonly yes

把redis-server的可执行文件复制到cluster下面的各个目录, 然后打开6个shell终端，进入各个目录，启动每个实例, 命令如下: 
./redis-server redis.conf

 

搭建集群
./redis-trib.rb create --replicas 1 127.0.0.1:6379 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

–replicas 1 表示我们希望为集群中的每个主节点创建一个从节点。
此时报错，发现缺少相应的ruby环境，如下安装相应环境：
yum install ruby
yum install rubygems
gem install redis

安装好环境后再次搭建集群
./redis-trib.rb create --replicas 1 127.0.0.1:6379 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 

 

检测集群节点相关信息 
./redis-trib.rb check 127.0.0.1:6379 

 

进入某个节点验证
./redis-cli -c -h 127.0.0.1 -p 6379
