部署
① 環境準備
準備三臺機器（192.168.124.1、192.168.124.2、192.168.124.3），每臺部署兩個Redis例項
- 192.168.124.1部署7001,7002埠例項的Redis
- 192.168.124.2部署7003,7004埠例項的Redis
- 192.168.124.3部署7005,7006埠例項的Redis
②修改配置檔案
修改每個例項的redis.conf配置檔案
- port 7001
- bind 0.0.0.0（允許所有ip客戶端的訪問）
- requirepass 123456（設定密碼，也可以不設定）
- daemonize yes
- pidfile /opt/redis-4.0.11/7001/redis_7001.pid
③安裝ruby
yum -y install ruby ruby-devel rubygems rpm-build
gem install redis④啟動例項
與單點的redis的啟動方式一樣，分別啟動六個redis的例項
./redis-server ../redis.conf &⑤開放埠
- redis客戶端連線的埠
192.168.124.1的7001,7002；192.168.124.2的7003,7004；192.168.124.3的7005,7006埠
- 叢集中例項相互通訊的內部匯流排埠（redis客戶端連線的埠 + 10000）
192.168.124.1的17001,17002；192.168.124.2的17003,17004；192.168.124.3的17005,17006埠
⑥叢集配置
在任意一個redis的src目錄執行
./redis-trib.rb create --replicas 1 192.168.37.133:7001 192.168.37.133:7002 192.168.37.134:7003 192.168.37.134:7004 192.168.37.135:7005 192.168.37.135:7006結果
