**redis  一直 Waiting for the cluster to join......... **

网上有的说 删除dump 和 nodes 文件，重启 ，我试了之后不行。

也有的说什么端口16379 被防火墙屏蔽了，也不行。后来 是因为内存不够了。

杀掉一些进程后  删除了所有节点的 dump 和 nodes 文件 然后再执行一次 集群创建 就成功了。

报错：

./redis-trib.rb 报错：/usr/local/rvm/gems/ruby-2.4.2/gems/redis-4.0.1/lib/redis/client.rb:119:in \`call'

**错误提示是**

**      slot插槽被占用了（这是 搭建集群前时，以前redis的旧数据和配置信息没有清理干净。）**

**解决方案是**

**          用redis-cli 登录到每个节点执行  flushall  和 cluster reset  就可以了。**

**然后重新执行群集脚本命令：**

**./redis-trib.rb create --replicas 1 192.168.\*.\*:7001 192.168.\*.\*:7002 192.168.\*.\*:7003 192.168.\*.\*:7004 192.168.\*.\*:7005  192.168.\*.\*:7006**

/usr/local/lib/ruby/gems/2.4.0/gems/redis-4.0.0/lib/redis/client.rb:119:in \`call': ERR Slot 0 is already busy (Redis::CommandError) from /usr/local/lib/ruby/gems/2.4.0/gems/redis-4.0.0/lib/redis.rb:2742:in \`block in method\_missing' from /usr/local/lib/ruby/gems/2.4.0/gems/redis-4.0.0/lib/redis.rb:45:in \`block in synchronize' from /usr/local/lib/ruby/2.4.0/monitor.rb:214:in \`mon\_synchronize' from /usr/local/lib/ruby/gems/2.4.0/gems/redis-4.0.0/lib/redis.rb:45:in \`synchronize' from /usr/local/lib/ruby/gems/2.4.0/gems/redis-4.0.0/lib/redis.rb:2741:in \`method\_missing' from src/redis-trib.rb:212:in \`flush\_node\_config' from src/redis-trib.rb:906:in \`block in flush\_nodes\_config' from src/redis-trib.rb:905:in \`each' from src/redis-trib.rb:905:in \`flush\_nodes\_config' from src/redis-trib.rb:1426:in \`create\_cluster\_cmd' from src/redis-trib.rb:1830:in \`<main>'

把所有节点下的 dump.rdb  和 nodes.conf  删除，然后 节点全部重启一下 在执行

**./redis-trib.rb create --replicas 1 192.168.\*.\*:7001 192.168.\*.\*:7002 192.168.\*.\*:7003 192.168.\*.\*:7004 192.168.\*.\*:7005  192.168.\*.\*:7006 **

**就可以了**
