1.刪除機器上原有的redis2.8

關閉redis-server

killall -9 redis-server

查找redis文件所在目錄

which redis

刪除相關文件

rm -rf redis rm -rf redis-proxy/ rm -rf nutcracker/

刪除相關命令

rm -f /usr/local/bin/redis-*

2.下載、安裝redis

wget http://download.redis.io/releases/redis-4.0.1.tar.gz tar xzf redis-4.0.1.tar.gz mv redis-4.0.1 /usr/local/ cd /usr/local/redis-4.0.1/ make make test

3.配置節點（新建6個以端口號命名的目錄，表示6個節點，3主3從）

cd /usr/local mkdir cluster cd cluster/ mkdir 7000 mkdir 7001 mkdir 7002 mkdir 7003 mkdir 7004 mkdir 7005

在上面新建的每個目錄下新建redis.conf文件，并寫入以下內容：

port 7000 cluster-enabled yes cluster-config-file nodes.conf cluster-node-timeout 5000 appendonly yes protected-mode no vim 7000/redis.conf vim 7001/redis.conf vim 7002/redis.conf vim 7003/redis.conf vim 7004/redis.conf vim 7005/redis.conf

為了方便使用把redis-server文件復制到/usr/local/cluster目錄下

cp /usr/local/redis-4.0.1/src/redis-server /usr/local/cluster

進入每個節點的目錄，并用對應的配置文件啟動redis

cd /usr/local/cluster/7000 ../redis-server ./redis.conf &

先測試一下是否啟動成功過，

/usr/local/redis-4.0.1/src/redis-cli -p 7000

如果能進去redis命令行表示啟動成功，再去啟動其他端口

cd /usr/local/cluster/7001 ../redis-server ./redis.conf & cd /usr/local/cluster/7002 ../redis-server ./redis.conf & cd /usr/local/cluster/7003 ../redis-server ./redis.conf & cd /usr/local/cluster/7004 ../redis-server ./redis.conf & cd /usr/local/cluster/7005 ../redis-server ./redis.conf &

接下來啟動cluster

cd /usr/local/redis-4.0.1/src/ ./redis-trib.rb create --replicas 1 172.16.180.226:7000 172.16.180.226:7001 172.16.180.226:7002 172.16.180.227:7003 172.16.180.227:7004 172.16.180.227:7005

4.常見錯誤及解決方法

如果系統上各種依賴比較齊全的話，這時就能啟動成功了，通常還可能遇到以下錯誤

錯誤1：

root@localhost src]# ./redis-trib.rb create --replicas 1 172.16.180.226:7000 172.16.180.226:7001 172.16.180.226:7002 172.16.180.227:7003 172.16.180.227:7004 172.16.180.227:7005 /usr/bin/env: ruby: No such file or directory

解決方案：

yum install ruby

錯誤2：

[root@localhost src]# ./redis-trib.rb create --replicas 1 172.16.180.226:7000 172.16.180.226:7001 172.16.180.226:7002 172.16.180.227:7003 172.16.180.227:7004 172.16.180.227:7005 ./redis-trib.rb:24:in `require': no such file to load -- rubygems (LoadError)from ./redis-trib.rb:24

解決方案：

yum install rubygems

錯誤3：

[root@localhost src]# ./redis-trib.rb creat --replicas 1 172.16.180.226:7000 172.16.180.226:7001 172.16.180.226:7002 172.16.180.227:7003 172.16.180.227:7004 172.16.180.227:7005 /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- redis (LoadError)from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'from ./redis-trib.rb:25

解決方案：

gem install redis

yum install ruby yum install rubygems gem install redis

安裝完以上各種依賴之后，再次執行以下命令即可成功啟動cluster

./redis-trib.rb create --replicas 1 172.16.180.226:7000 172.16.180.226:7001 172.16.180.226:7002 172.16.180.227:7003 172.16.180.227:7004 172.16.180.227:7005

5.測試cluster集群是否能正常使用

/usr/local/src/redis-cli -c -h 172.16.180.226 -p 7000

上面的命令如果缺少了“-c”會出現以下錯誤。

6.編寫重啟cluster的shell腳本

vim restart-cluster.sh

寫入以下內容：

#!/bin/sh killall -9 redis-server #刪掉以前運行的節點留下的配置信息 find /usr/local/cluster/ -name "appendonly.aof"|xargs rm -f; find /usr/local/cluster/ -name "nodes.conf"|xargs rm -f; find /usr/local/cluster/ -name "dump.rdb"|xargs rm -f; #重新啟動redis cd /usr/local/cluster/7000 ../redis-server ./redis.conf & cd /usr/local/cluster/7001 ../redis-server ./redis.conf & cd /usr/local/cluster/7002 ../redis-server ./redis.conf & cd /usr/local/cluster/7003 ../redis-server ./redis.conf & cd /usr/local/cluster/7004 ../redis-server ./redis.conf & cd /usr/local/cluster/7005 ../redis-server ./redis.conf & cd /usr/local/redis-4.0.1/src/ #重新創建cluster集群 ./redis-trib.rb create --replicas 1 127.0.0.1:7000 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

shell文件保存之后需要賦予可執行權限。

chmod +x restart-cluster.sh

使用腳本重啟

./restart-cluster.sh

查看是否重啟成功

src/redis-cli -c -p 7000
