開始部署之前，務必先看最后一條
- 從官網(wǎng)下載和編譯redis安裝包
$ wget http://download.redis.io/releases/redis-3.2.5.tar.gz
$ tar xzf redis-3.2.5.tar.gz
$ cd redis-3.2.5
$ make
- 配置redis
創(chuàng)建redis.conf, 內容如下
port 7000
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes
如果你不想做持久化的話，appendonly yes 改為 appendonly no,假設我們部署3個redis nodes, 那么需要創(chuàng) 建6個redis實例，其中3個node為master另外3個nodes的slave;
mkdir cluster-test
cd cluster-test
mkdir 7000 7001 7002 7003 7004 7005
將redis.conf分別拷貝一份到這6個文件夾下，保證這6個目錄下的redis.conf的port 分別為7000~7005
- 啟動所有redis實例
分別進入六個目錄，啟動相應的redis-server
cd 7000
../redis-server ./redis.conf
cd ../7001
../redis-server ./redis.conf
cd ../7002
../redis-server ./redis.conf
cd ../7003
../redis-server ./redis.conf
cd ../7004
../redis-server ./redis.conf
cd ../7005
../redis-server ./redis.conf
- 安裝redis-trib.rb運行環(huán)境
redis-trib.rb是ruby代碼，所以先要安裝ruby
yum install ruby
gem install redis -- 安裝redis依賴
因為墻的問題，gem install redis 可能會失敗，改用國內的源
gem sources --remove https://rubygems.org/ 刪掉原來的源
gem sources -a https://gems.ruby-china.com/ 改用國內的源
gem sources -l 查看現(xiàn)有的源
gem install redis 安裝redis依賴
- 創(chuàng)建集群
./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
- 注意的地方
使用redis-trib.rb構建集群,完成前不要配置密碼
集群構建完再通過config set + config rewrite命令逐個實例設置密碼
對集群設置密碼，requirepass和masterauth都需要設置
-
各個節(jié)點密碼都必須一致，否則Redirected就會失敗
config set masterauth yourpasswd config set requirepass yourpasswd auth yourpasswd config rewrite -
如果提示一下錯誤，那么是redis依賴版本錯誤，移除當前redis依賴，安裝指定版本即可
