下载redis

wget http://download.redis.io/releases/redis-3.2.9.tar.gz

解压

tar zxvf redis-3.2.9.tar.gz

可能需要安装redis-3.0.0.gem

yum install redis-3.0.0.gem

安装到指定路径/usr/local/redis

cd redis-3.2.9
make && make PREFIX=/usr/local/redis install

如果失败，请使用yum安装gcc和tcl

yum install gcc
yum install tcl

创建自定义目录，存放多个自定义redis

mkdir redis-cluster

复制安装的redis目录为多个实例，命令redis01、redis02、redis03、redis04、redis05、redis06

cp -r redis ./redis-cluster/redis01
cp -r redis ./redis-cluster/redis02
cp -r redis ./redis-cluster/redis03
cp -r redis ./redis-cluster/redis04
cp -r redis ./redis-cluster/redis05
cp -r redis ./redis-cluster/redis06

copy解压目录redis-3.2.9/redis.conf配置文件到redis01/etc,redis02/etc,redis03/etc,redis04/etc,redis05/etc,redis06/etc下面

cp redis-3.2.9/redis.conf /usr/local/redis-cluster/redis02/etc/redis.conf
cp redis-3.2.9/redis.conf /usr/local/redis-cluster/redis03/etc/redis.conf
cp redis-3.2.9/redis.conf /usr/local/redis-cluster/redis04/etc/redis.conf
cp redis-3.2.9/redis.conf /usr/local/redis-cluster/redis05/etc/redis.conf
cp redis-3.2.9/redis.conf /usr/local/redis-cluster/redis01/etc/redis.conf

编辑多个实例下面的redis.conf，将45行端口分别改为7001-7006，配置后台启动daemonize修改为yes，632行开启集群cluster-enabled改为yes

[root@localhost redis-cluster]# ./start-all.sh 
[root@localhost redis-cluster]# 

进入redis-cluster目录

cd /usr/local/redis-cluster

创建启动脚本start-all.sh

touch start-all.sh

编辑start-all.sh

vi start-all.sh

写入并保存退出

cd redis01/
./bin/redis-server ./etc/redis.conf
cd ../
cd redis02/
./bin/redis-server ./etc/redis.conf
cd ../
cd redis03/
./bin/redis-server ./etc/redis.conf
cd ../
cd redis04/
./bin/redis-server ./etc/redis.conf
cd ../
cd redis05/
./bin/redis-server ./etc/redis.conf
cd ../
cd redis06/
./bin/redis-server ./etc/redis.conf
cd ../

修改start-all.sh的执行权限

chmod -x start-all.sh

启动脚本，如下表示成功

./start-all.sh

查看进程

[root@localhost redis-cluster]# ps -ef|grep redis

root       9954   2590  0 13:06 pts/0    00:00:00 grep --color=auto redis

复制redis-3.2.9/src/redis-trib.rb到redis-cluster目录

cp redis-3.2.9/src/redis-trib.rb /usr/local/redis-cluster

进入/usr/local/redis-cluster，启动集群

./redis-trib.rb create 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 127.0.0.1:7006
