redis叢集伺服器


1.提供伺服器抵抗災害的能力
2.提高效率



我們來搞兩臺虛擬機器
然後各搞3個redis服務

一共6個redis服務





//先檢視??的 gem 源是什麼地址
gem source -l // 如果是https://rubygems.org/ 就需要更換
// 更換指令為
gem sources --add https://gems.ruby-china.com --remove https://rubygems.org/
// 通過 gem 安裝 redis 的相關依賴
sudo gem install redis
// 然後重新執?指令
redis-trib.rb create --replicas 1 192.168.110.37:7000 192.168.110.37:7001 192.168.110.37:7002 192.168.110.38:7003 192.168.110.38:7004 192.168.110.38:7005





go語言redis-cluster開源客戶端
安裝：
go get github.com/gitstliu/go-redis-cluster
示例程式碼
func (this*ClusterController)Get(){
	cluster, _ := redis.NewCluster(
		&redis.Options{
			StartNodes: []string{"192.168.110.37:7000", "192.168.110.37:7001", "192.168.110.37:7002","192.168.110.38:7003","192.168.110.38:7004","192.168.110.38:7005"},
			ConnTimeout: 50 * time.Millisecond,
			ReadTimeout: 50 * time.Millisecond,
			WriteTimeout: 50 * time.Millisecond,
			KeepAlive: 16,
			AliveTime: 60 * time.Second,
		})
	cluster.Do("set","name","itheima")

	name,_ := redis.String(cluster.Do("get","name"))
	beego.Info(name)
	this.Ctx.WriteString("叢集建立成功")
}
