redis3.0安装错误总结

1. 配置完所有主节点后,报" ERR Invalid node address specified"

   由于redis-trib.rb 对域名或主机名支持不好,故在创建集群的时候要使用ip:port的方式

   redis-trib.rb create ip1:port1 ip2:port2 ip3:port3

    

2. 创建集群时报某个err slot 0 is already busy (redis::commanderror)

   这是由于之间创建集群没有成功,需要将nodes.conf和dir里面的文件全部删除(注意不要删除了redis.conf)

    

3. 创建集群时一直处于"Waiting for the cluster to join...................................."的状态

   这个问题原因不知,但解决方法是在redis.conf文件中把bind 127.0.0.1本地环回口改为物理接口.

    

4. 安装ruby redis时长时间没响应

   这是由于天朝网络,解决办法是改ruby源(请自行baidu)或手动安装

   经检查，这是由于上一次配置集群失败时留下的配置信息导致的。 只要把redis.conf中定义的 cluster-config-file 所在的文件删除，重新启动redis-server及运行redis-trib即可。
