介于有人需要，总结一下，不保证对

1、下载redis-3.0.0.tar.gz (必须3.0.0及之后版本，之前版本不支持集群模式)

下载：wget http://download.redis.io/releases/redis-3.0.0.tar.gz

1
tar -zxvf redis-3.0.0.tar.gz -C /usr/local/

重命名(如果嫌名字太长，可重命名，我这里就改一下)

1
2
mv /usr/local/redis-3.0.0 /usr/local/redis3.0
cd /usr/local/redis3.0

编译

1
make

未make install时，/usr/local/redis3.0/src/目录下没有redis-cli、redis-server 等启动脚本

1
cd /usr/local/redis3.0/src/

2、安装

1
make install

是否安装成功，可观察/usr/local/redis3.0/src/目录下redis-cli、redis-server 等脚本

3、为了方便操作，同时不影响源文件，这里进行以下操作

1
2
mkdir -p /usr/local/redis/bin
mv mkreleasehdr.sh redis-benchmark redis-check-aof redis-check-dump redis-cli redis-server /usr/local/redis/bin

4、创建redis-cluster文件夹，并在下面创建6个文件夹（一般集群最少6个，3主3从）

1
2
3
mkdir -p /usr/local/redis-cluster
cd /usr/local/redis-cluster
mkdir 7001 7002 7003 7004 7005 7006

5、将/usr/local/redis3.0/redis.conf配置文件分别copy到700*文件下，分别进行修改

1
2
cp /usr/local/redis3.0/redis.conf /usr/local/redis-cluster/7001
vi /usr/local/redis-cluster/7001/redis.conf

修改如下：

1
2
3
4
5
6
7
8
daemonize yes # 后台启动
port 7001 # 端口
bind 192.168.0.228 # 服务器IP
dir /usr/local/redis-cluster/7001/ # 数据存放位置，每个节点路径不一样
cluster-enabled yes # 启动集群模式
cluster-config-file nodes-7001.conf # 名称最好与端口一致
cluster-node-timeout 5000 # 5000毫秒
appendonly yes #

简单操作

1
2
3
4
5
sed 's/7001/7002/g' /usr/local/redis-cluster/7001/redis.conf > /usr/local/redis-cluster/7002/redis.conf
sed 's/7001/7003/g' /usr/local/redis-cluster/7001/redis.conf > /usr/local/redis-cluster/7003/redis.conf
sed 's/7001/7004/g' /usr/local/redis-cluster/7001/redis.conf > /usr/local/redis-cluster/7004/redis.conf
sed 's/7001/7005/g' /usr/local/redis-cluster/7001/redis.conf > /usr/local/redis-cluster/7005/redis.conf
sed 's/7001/7006/g' /usr/local/redis-cluster/7001/redis.conf > /usr/local/redis-cluster/7006/redis.conf

6、由于redis使用到ruby命令，先需安装ruby

1
2
3
yum install ruby # 存在依赖，按y
yum install rubygems # 存在依赖，按y
gem install redis # 安装redis和ruby接口

安装失败 就进行下面操作:

1
2
3
4
5
6
7
8
9
10
11
curl -L get.rvm.io | bash -s stable
gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
curl -sSL https://get.rvm.io | bash -s stable
source /usr/local/rvm/scripts/rvm
rvm list known
rvm install 2.3.0
rvm use 2.3.0
rvm remove 1.8.7
ruby --version
gem install redis
yum install -y rubygems

7、启动6个redis

1
2
3
4
5
6
/usr/local/redis/bin/redis-server /usr/local/redis-cluster/7001/redis.conf
/usr/local/redis/bin/redis-server /usr/local/redis-cluster/7002/redis.conf
/usr/local/redis/bin/redis-server /usr/local/redis-cluster/7003/redis.conf
/usr/local/redis/bin/redis-server /usr/local/redis-cluster/7004/redis.conf
/usr/local/redis/bin/redis-server /usr/local/redis-cluster/7005/redis.conf
/usr/local/redis/bin/redis-server /usr/local/redis-cluster/7006/redis.conf

查看是否启动完成

1
ps -ef | grep redis

或

1
netstat -tunpl | grep redis

8、创建集群

1
/usr/local/redis3.0/src/redis-trib.rb create --replicas 1 192.168.0.228:7001 192.168.0.228:7002 192.168.0.228:7003 192.168.0.228:7004 192.168.0.228:7005 192.168.0.228:7006

create表示创建
1=主/从(比值)
按顺序
主节点：192.168.0.228:7001 192.168.0.228:7002 192.168.0.228:7003
从节点：192.168.0.228:7004 192.168.0.228:7005 192.168.0.228:7006
192.168.0.228:7004 是 192.168.0.228:7001 的从节点
创建过程会询问，yes即可

9、进入集群环境

进入redis客户端，-c 表示集群模式，-h 表示服务器地址， -p 表示端口

1
/usr/local/redis/bin/redis-cli -c -h 192.168.0.228 -p 7001

如果拒绝连接
第一步启动

1
2
3
4
5
6
7
redis-server /usr/local/redis-cluster/7001/redis.conf
redis-server /usr/local/redis-cluster/7002/redis.conf
redis-server /usr/local/redis-cluster/7003/redis.conf
redis-server /usr/local/redis-cluster/7004/redis.conf
redis-server /usr/local/redis-cluster/7005/redis.conf
redis-server /usr/local/redis-cluster/7006/redis.conf
redis-cli

然后进入集群环境

1
/usr/local/redis/bin/redis-cli -c -h 192.168.0.228 -p 7001

退出redis客户端

1
192.168.0.228:7001> quit

关闭redis服务

1
/usr/local/redis/bin/redis-cli shutdown

注：电脑性能不好，实际环境中自行改成不同机器IP即可收起
