收集整理的這篇文章主要介紹了
Redis 3.0.2集群搭建以及相关问题汇总
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
Redis3 正式支持了 cluster，是為了解決構建redis集群時的諸多不便
現在想添加一個redis節點，可以從 節點1、節點2、節點3?中各拿出一部分的slot，移到新節點
每個redis節點中的slot數量可以不一致，根據節點性能適當分配 進入集群需要用redis -c -p 7000 ? ?-c是enable cluster ? p指定進入端口 搭建集群遇到的問題： 由于教程里面給出的集群的地址是127.0.0.1:7000、......，在java程序訪問的時候是無法獲取節點信息的，所以我需要重新搭建集群，然后停掉所有節點，重新搭建的時候，報出了如下錯誤，可知是因為有些配置文件以及數據沒有刪除。將其全部刪除干凈即可。 [ERR] Node 172.168.63.202:7001 is not empty.

??? 從服務器：
??? 127.0.0.1:7003
??? 127.0.0.1:7004
??? 127.0.0.1:7005
??? 步驟：
??? 1,下載redis。官網下載3.0.0版本，之前幾的版本不支持集群模式
??? 下載地址：http://download.redis.io/releases/redis-3.0.0.tar.gz
??? 2：上傳服務器，解壓，編譯
??? tar -zxvf redis-3.0.0-rc2.tar.gz
??? mv redis-3.0.0-rc2.tar.gz redis3.0
??? cd /usr/local/redis3.0
??? make & make install
??? 3：創建集群需要的目錄并拷貝redis
??? mkdir -p /usr/local/cluster
??? mkdir -p /usr/local/cluster/7000
??? mkdir -p /usr/local/cluster/7001
??? mkdir -p /usr/local/cluster/7002
??? mkdir -p /usr/local/cluster/7003
??? mkdir -p /usr/local/cluster/7004
??? mkdir -p /usr/local/cluster/7005
??? cp -rf /usr/local/redis3.0/* /usr/local/cluster/7000/
??? cp -rf /usr/local/redis3.0/* /usr/local/cluster/7001/
??? cp -rf /usr/local/redis3.0/* /usr/local/cluster/7002/
??? cp -rf /usr/local/redis3.0/* /usr/local/cluster/7003/
??? cp -rf /usr/local/redis3.0/* /usr/local/cluster/7004/
??? cp -rf /usr/local/redis3.0/* /usr/local/cluster/7005/
??? 4：修改配置文件redis.conf
??? vi /usr/local/cluster/7000/redis.conf
??? ##修改配置文件中的下面選項
??? port 7000
??? daemonize yes
??? cluster-enabled yes
??? cluster-config-file nodes.conf
??? cluster-node-timeout 5000
??? appendonly yes
??? #同樣再對其它配置文件進行修改
??? vi /usr/local/cluster/7001/redis.conf
??? vi /usr/local/cluster/7002/redis.conf
??? vi /usr/local/cluster/7003/redis.conf
??? vi /usr/local/cluster/7004/redis.conf
??? vi /usr/local/cluster/7005/redis.conf
??? ##注意：不同的目錄配置不同的redis.conf中的port
??? 5：啟動6個redis
??? cd /usr/local/cluster/7000/src
??? redis-server ../redis.conf
??? cd /usr/local/cluster/7001/src
??? redis-server ../redis.conf
??? cd /usr/local/cluster/7002/src
??? redis-server ../redis.conf
??? cd /usr/local/cluster/7003/src
??? redis-server ../redis.conf
??? cd /usr/local/cluster/7004/src
??? redis-server ../redis.conf
??? cd /usr/local/cluster/7005/src
??? redis-server ../redis.conf
??? ##啟動之后使用命令查看redis的啟動情況ps -ef|grep redis
??? 6,創建redis集群
??? cd /usr/local/redis3.0/src
??? ./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
??? 6.1執行上面的命令的時候會報錯，因為是執行的的腳本，需要
??? 錯誤內容：/usr/bin/env: ruby: No such file or directory
??? 所以需要安裝ruby的環境，這里推薦使用yum install ruby
??? yum install ruby
??? 6.2然后再執行第步的創建集群命令，還會報錯，提示缺少rubygems組件
??? 錯誤內容：
??? ./redis-trib.rb:24:in `require': no such file to load -- rubygems (LoadError)
??? from ./redis-trib.rb:24
??? yum install rubygems
??? 6.3再次執行第步的命令，還會報錯，提示不能加載redis，是因為缺少redis的接口
??? 錯誤內容：
??? /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
??? gem install redis
??? 這里可能無法安裝,因為無法連接gem服務器：
??? [@zw_22_90 src]# gem install redis --version 3.0.0
??? ERROR: Could not find a valid gem 'redis' (= 3.0.0) in any repository
??? ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)
??? 6.4 再次執行第步的命令，正常執行
??? 輸入yes，然后配置完成。

??? 7，redis-cli命令進入集群環境
??? [@zw_22_90 src]# redis-cli -c -p 7000
??? 127.0.0.1:7000> quit;
（1）像操作單個redis一樣操作key，不用操心key在哪個節點上
（2）在線動態添加、刪除redis節點，不用停止服務
（3）根據節點性能，動態分配不同數量的key到不同redis節點
（4）每個節點都配有slave，并自動監測和切換
?
Redis3 cluster 中增加了一個重要概念：
hash slot（哈希槽），共有16384個slot
key不是直接放入redis中了，而是放入slot中，再把slot放入redis中
根據key的hash值計算其所在的slot，再根據slot和redis節點的對應關系，找到此slot所在的節點，然后到這個節點對key進行操作
例如現有3個redis節點，每個節點各負責一半數量的slot，16384/3 = 5461個現在想添加一個redis節點，可以從 節點1、節點2、節點3?中各拿出一部分的slot，移到新節點
每個redis節點中的slot數量可以不一致，根據節點性能適當分配 進入集群需要用redis -c -p 7000 ? ?-c是enable cluster ? p指定進入端口 搭建集群遇到的問題： 由于教程里面給出的集群的地址是127.0.0.1:7000、......，在java程序訪問的時候是無法獲取節點信息的，所以我需要重新搭建集群，然后停掉所有節點，重新搭建的時候，報出了如下錯誤，可知是因為有些配置文件以及數據沒有刪除。將其全部刪除干凈即可。 [ERR] Node 172.168.63.202:7001 is not empty.
