伺服器

CentOS
Centos 伺服器初始環境配置最好先配置好，伺服器時間最好配置為一致
我用的是6個伺服器，一個伺服器一個埠，便於配置檔案的修改

首先下載redis3 到本地(需要3以後的版本，我下載的最新的版本:3.0.4)

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

分別上傳到每個伺服器

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

分別在每個伺服器上安裝 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如果裝不上，可多試幾次，若是ubuntu，換源，換成taobao,建議伺服器用centOS)

解壓安裝redis

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

修改配置檔案redis.conf 以埠9000為例

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

然後分別在每個伺服器上啟動redis

src/redis-server redis.conf

檢視每個埠是否成功開啟

ps -aux | grep redis

結果如下：

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

如果後面有[cluster] 證明開啟成功

然後建立叢集

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 至少有三個 1 代表 一個master 對應一個slave)

如果下面這樣就代表成功(埠 9000 )
