三臺伺服器：先設定hosts
10.0.0.231  node1
10.0.0.232  node2
10.0.0.233  node3

埠分配：
node1:7000 
node1:7001  
node2:7002  
node2:7003  
node3:7004  
node3:7005

1：下載redis-4.0.1並解壓

解壓目錄：/usr/local/redis-4.0.1
建立軟連線：ln -s redis-4.0.1 redis

2：編譯安裝

指定安裝目錄到:/usr/local/redis

make && make install PREFIX=/usr/local/redis

3：建立配製節點

node1伺服器:
mkdir -p /usr/loca/redis/redis_cluster/7000
 

mkdir -p /usr/loca/redis/redis_cluster/7001

cp /usr/local/redis/redis.conf /usr/loca/redis/redis_cluster/7000
cp /usr/local/redis/redis.conf /usr/loca/redis/redis_cluster/7001

node2伺服器:
mkdir -p /usr/loca/redis/redis_cluster/7002
mkdir -p /usr/loca/redis/redis_cluster/7003

cp /usr/local/redis/redis.conf /usr/loca/redis/redis_cluster/7002
cp /usr/local/redis/redis.conf /usr/loca/redis/redis_cluster/7003
 


node3伺服器:
mkdir -p /usr/loca/redis/redis_cluster/7004
mkdir -p /usr/loca/redis/redis_cluster/7005

cp /usr/local/redis/redis.conf /usr/loca/redis/redis_cluster/7004
cp /usr/local/redis/redis.conf /usr/loca/redis/redis_cluster/7005

4：修改redis.conf

切記：不能設定密碼，否則叢集啟動時會連線不上

port  7000                                //埠根據對應的資料夾去配製埠 7000,7001,7002,7003,7004,7005      
 

bind 本機ip                               //根據本機所在的IP或hostname去配製 node1 node2 node3
daemonize    yes                          //redis後臺執行
pidfile  /var/run/redis_7000.pid          //pidfile檔案對應7000,7001,7002,7003,7004,7005
cluster-enabled  yes                      //開啟叢集  把註釋#去掉
cluster-config-file  nodes_7000.conf      //叢集的配置  配置檔案首次啟動自動生成 7000,7001,7002,7003,7004,7005
cluster-node-timeout  15000               //請求超時  預設15秒，可自行設定
appendonly  yes                           //aof日誌開啟  有需要就開啟，它會每次寫操作都記錄一條日誌

5：複製src目錄中的redis-trib.rb 到/usr/local/redis/bin目錄

cp  /usr/local/redis/redis-trib.rb /usr/local/redis/bin

6：安裝ruby環境

yum install -y ruby
yum install -y rubygems

7：安裝ruby的包

gem install redis-4.0.0.rc1.gem

如果不成功需要去下載後安裝
下載地址
https://rubygems.org/gems/redis/versions/4.0.0.rc1
https://rubygems.org/downloads/redis-4.0.0.rc1.gem

安裝命令：gem install -l ./redis-4.0.0.rc1.gem

8：啟動各個節點

node1伺服器:
/usr/local/redis/bin/redis-server /usr/loca/redis/redis_cluster/7000/redis.conf
/usr/local/redis/bin/redis-server /usr/loca/redis/redis_cluster/7001/redis.conf

node2伺服器:
/usr/local/redis/bin/redis-server /usr/loca/redis/redis_cluster/7002/redis.conf
/usr/local/redis/bin/redis-server /usr/loca/redis/redis_cluster/7003/redis.conf

node3伺服器:
/usr/local/redis/bin/redis-server /usr/loca/redis/redis_cluster/7004/redis.conf
/usr/local/redis/bin/redis-server /usr/loca/redis/redis_cluster/7005/redis.conf

9：檢查各節點是否啟動

檢視程序
ps -ef | grep redis

檢視埠
netstat -tnlp | grep redis

 10：建立叢集

進入node1的bin目錄下,執行以下指令碼
./redis-trib.rb  create  --replicas  1  node1:7000 node1:7001  node2:7002  node2:7003  node3:7004  node3:7005

11：驗證叢集

進入每臺伺服器的redis/src目錄,記住引數  -c不可以少

redis-cli -h node1 -p 7000 -c

redis-cli -h node2 -p 7002 -c

redis-cli -h node3 -p 7004 -c
