安装redis-3.2.3
1:wget –no-check-certificate http://download.redis.io/releases/redis-3.2.3.tar.gz
2:tar xzf redis-3.2.3.tar.gz
3:mv redis-3.2.3 usr/local/redis-3.2.3
4:cd usr/loacl/redis-3.2.3
5:make
6:make test
创建集群所需要的目录
mkdir /home/redis-cluster/{9000,9001,9002,9003,9004,9005}
cp ~/redis-3.2.3/redis.conf /home/redis-cluster/9000
..
..
cp ~/redis-3.2.3/redis.conf /home/redis-cluster/9005
修改配置文件redis.conf
vim /home/redis-cluster/9000/redis.conf
daemonize yes
port 9000 (端口为目录对应名字即每个redis实例所占的端口号)
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes
分别启动这6个redis实例
/redis-3.2.3/src/redis-server /home/redis-cluster/9001/redis.conf
/redis-3.2.3/src/redis-server /home/redis-cluster/9002/redis.conf
/redis-3.2.3/src/redis-server /home/redis-cluster/9003/redis.conf
/redis-3.2.3/src/redis-server /home/redis-cluster/9004/redis.conf
/redis-3.2.3/src/redis-server /home/redis-cluster/9005/redis.conf
启动之后使用命令查看redis的启动情况ps -ef|grep redis
如下图则说明成功
执行redis的创建集群命令创建集群
/redis-3.2.3/src/redis-trib.rb create –replicas 1 192.168.59.132:9000 192.168.59.132:9001 192.168.59.132:9002 192.168.59.132:9003 192.168.59.132:9004 192.168.59.132:9005
执行上面的命令的时候会报错，因为是执行的ruby的脚本，需要ruby的环境
错误内容：/usr/bin/env: ruby: No such file or directory
所以需要安装ruby的环境，这里推荐使用yum install ruby安装
yum install ruby
然后再执行创建集群命令，还会报错，提示缺少rubygems组件，使用yum安装
错误内容：
./redis-trib.rb:24:in `require': no such file to load --rubygems (LoadError)
from ./redis-trib.rb:24
yum install rubygems
再次命令，还会报错，提示不能加载redis，是因为缺少redis和ruby的接口，使用gem 安装 错误内容：
/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load
-- redis (LoadError)from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'from ./redis-trib.rb:25
gem install redis
再次执行命令，正常执行 如图
好啦 redis集群即搭建成功
