基于redhat linux来安装
前置：安装了yum（因为需要装ruby等软件，使用yum install很容易就安装了，安装yum见http://eip.teamshub.com/t/3111540）
1、将【redis-3.0.5.tar.gz】放到home/redis目录；
2、解压
tar
-zxvf redis-3.0.5.tar.gz
3、进到目录去编译
cd
redis-3.0.5
make
4、创建集群需要的目录
mkdir -p
/home/redis/redis-3.0.5/cluster-test
cd
/home/redis/redis-3.0.5/cluster-test
mkdir 7000
mkdir 7001
mkdir
7002
mkdir 7003
mkdir 7004
mkdir 7005
5、修改配置文件redis.conf
cd
/home/redis/redis-3.0.5/cluster-test/7000
vi
redis.conf
##编辑文件中的内容为下面内容：
port 7000
daemonize yes
#这个可有可无，得看看是什么配置项
cluster-enabled yes
cluster-config-file
nodes.conf
cluster-node-timeout 5000
appendonly
yes
6、将7000的redis.conf配置文件，分别拷贝到7001/7002/7003/7004/7005目录下面
cp
/home/redis/redis-3.0.5/cluster-test/7000/redis.conf
/home/redis/redis-3.0.5/cluster-test/7001
cp
/home/redis/redis-3.0.5/cluster-test/7000/redis.conf
/home/redis/redis-3.0.5/cluster-test/7002
cp
/home/redis/redis-3.0.5/cluster-test/7000/redis.conf
/home/redis/redis-3.0.5/cluster-test/7003
cp
/home/redis/redis-3.0.5/cluster-test/7000/redis.conf
/home/redis/redis-3.0.5/cluster-test/7004
cp
/home/redis/redis-3.0.5/cluster-test/7000/redis.conf
/home/redis/redis-3.0.5/cluster-test/7005
7、对上一步拷贝完成之后要修改7001/7002/7003/7004/7005目录下面redis.conf文件中的port参数，分别改为对应的文件夹的名称
8、编写redis的启动脚本，如7000
cd
/home/redis/redis-3.0.5/cluster-test/7000
vi
start7000.sh
##在start7000.sh中编辑如下内容并保存：
cd
/home/redis/redis-3.0.5/cluster-test/7000
nohup
/home/redis/redis-3.0.5/src/redis-server redis.conf > redis7000.log
2>&1 &
#编辑保存好后，修改权限为可执行
chmod 777
start7000.sh
9、将start7000.sh的脚本，分别拷贝到7001/7002/7003/7004/7005目录下面
cp
/home/redis/redis-3.0.5/cluster-test/7000/start7000.sh
/home/redis/redis-3.0.5/cluster-test/7001/start7001.sh
cp
/home/redis/redis-3.0.5/cluster-test/7000/start7000.sh
/home/redis/redis-3.0.5/cluster-test/7002/start7002.sh
cp
/home/redis/redis-3.0.5/cluster-test/7000/start7000.sh
/home/redis/redis-3.0.5/cluster-test/7003/start7003.sh
cp
/home/redis/redis-3.0.5/cluster-test/7000/start7000.sh
/home/redis/redis-3.0.5/cluster-test/7004/start7004.sh
cp
/home/redis/redis-3.0.5/cluster-test/7000/start7000.sh
/home/redis/redis-3.0.5/cluster-test/7005/start7005.sh
10、对上一步拷贝完成之后要修改7001/7002/7003/7004/7005目录下面start700X.sh文件中的port参数，分别改为对应的文件夹的名称
11、分布启动各自路径下的start700X.sh，启动后，可以查看进程
[redis@localhost
7005]$ ps -ef|grep 700
redis 6063 1 0 22:56 ? 00:00:06
/home/redis/redis-3.0.5/src/redis-server *:7000 [cluster]
redis 28766
1 0 23:50 pts/2 00:00:00 /home/redis/redis-3.0.5/src/redis-server *:7001
[cluster]
redis 28795 1 0 23:52 pts/2 00:00:00
/home/redis/redis-3.0.5/src/redis-server *:7002 [cluster]
redis 28800
1 2 23:53 pts/2 00:00:00 /home/redis/redis-3.0.5/src/redis-server *:7003
[cluster]
redis 28817 1 0 23:53 pts/2 00:00:00
/home/redis/redis-3.0.5/src/redis-server *:7004 [cluster]
redis 28823
1 0 23:53 pts/2 00:00:00 /home/redis/redis-3.0.5/src/redis-server *:7005
[cluster]
redis 28831 28500 0 23:53 pts/2 00:00:00 grep
700
如在启动时遇到因为ulimit中nofile设置过小而启动不了，可以通过root用户去修改ulimit，给redis用户设置一下nofile
vim
/etc/security/limits.conf
加入以下两行
redis soft nofile 10240
redis hard nofile 20480
12、升级ruby，安装gem
安装gem需要ruby的版本在
1.8.7 以上，如果ruby版本低或没有装，则首先你的升级你的ruby
[root@localhost ~]# ruby -v
bash:
ruby: command not found
[root@localhost ~]# yum install ruby
检查 ruby
版本：
[root@localhost ~]# ruby -v
ruby 1.8.7 (2013-06-27 patchlevel 374)
[i386-linux]
检查是否安装了rubygems：
[root@localhost ~]# rpm -qa|grep
ruby
ruby-1.8.7.374-4.el6_6.i686
ruby-libs-1.8.7.374-4.el6_6.i686
如果没有rubygems，就安装
[root@localhost
~]# yum install rubygems
13、通过gem 安装redis ruby 接口
[root@localhost ~]#
gem install
redis
14、执行redis的创建集群命令创建集群
使用redis-trib.rb创建集群的用法说明：
#redis-trib.rb的create子命令构建
#--replicas
则指定了为Redis
Cluster中的每个Master节点配备几个Slave节点
#节点角色由顺序决定,先master之后是slave
创建命令：
/home/redis/redis-3.0.5/src/redis-trib.rb
create --replicas 1 127.0.0.1:7000 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003
127.0.0.1:7004 127.0.0.1:7005
[redis@localhost src]$
/home/redis/redis-3.0.5/src/redis-trib.rb create --replicas 1 127.0.0.1:7000
127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004

默认是前三个节点 7000 7001 7002 是主， 后3个节点 7003 7004 7005
是从
如果需要重新分配，则将所有节点停止后，将以下几个文件删除：
rm appendonly.aof dump.rdb
nodes.conf redis7005.log
删除后再重新运行redis-trib.rb
create命令添加组成集群。
15、监控集群状态命令
/home/redis/redis-3.0.5/src/redis-trib.rb
check 127.0.0.1:7000
[redis@localhost 7000]$
/home/redis/redis-3.0.5/src/redis-trib.rb check 127.0.0.1:7000

16、测试
使用redis-cli命令进入集群环境
/home/redis/redis-3.0.5/src/redis-cli
-c -p 7000
另外，当7000被杀掉时，7003会变为主节点；
