服务器

CentOS
Centos 服务器初始环境配置最好先配置好，服务器时间最好配置为一致
我用的是6个服务器，一个服务器一个端口，便于配置文件的修改

首先下载redis3 到本地(需要3以后的版本，我下载的最新的版本:3.0.4)

wget http://download.redis.io/releases/redis-3.0.4.tar.gz

分别上传到每个服务器

scp -r redis-3.0.4.tar.gz redis@redis1:~/

分别在每个服务器上安装 gcc tcl ruby rubygems gem_redis

sudo yum -y install gcc
sudo yum -y install tcl
sudo yum -y install ruby rubygems
sudo gem install redis --version 3.0.4

(gem_redis如果装不上，可多试几次，若是ubuntu，换源，换成taobao,建议服务器用centOS)

解压安装redis

tar -zxvf redis-3.0.4.tar.gz
cd redis-3.0.4/
sudo make test
sudo make install

修改配置文件redis.conf 以端口9000为例

sudo vim redis.conf

port 9000
pidfile /var/run/redis-9000.pid
dbfilename dump-9000.rdb
appendfilename "appendonly-9000.aof"
cluster-config-file nodes-9000.conf
cluster-enabled yes
cluster-node-timeout 5000
appendonly yes

然后分别在每个服务器上启动redis

src/redis-server redis.conf

查看每个端口是否成功开启

ps -aux | grep redis

结果如下：

redis 26674 1 0 Sep15 ? 00:01:21 src/redis-server *:9000 [cluster]

如果后面有[cluster] 证明开启成功

然后建立集群

src/redis-trib.rb create --replicas 1 192.168.32.195:9000 192.168.32.196:9000
192.168.32.197:9000 192.168.32.198:9000 192.168.32.199:9000 192.168.6.214:9000

(master 至少有三个 1 代表 一个master 对应一个slave)

如果下面这样就代表成功(端口 9000 )

以集群的方式登陆(9000为例）

redis-cli -c -p 9000
