centos redis 3,4集羣配置

一，解決ruby環境

https://blog.csdn.net/liuhaoy/article/details/104293482

二，修改配置文件

去掉兩行註釋

[root@youyou2 ~]# vi /apps/redis/etc/redis.conf 
cluster-enabled yes
cluster-config-file nodes-6379.conf

查看端口會有6379和16379 兩個端口

三，創建集羣

如果需要密碼請修改成自己集羣的密碼，集羣中redis 環境密碼設置一樣，或者不設置

[root@youyou1 ~]# cd /usr/src/redis-4.0.14/src/
[root@youyou1 src]# cat  /usr/local/lib/ruby/gems/2.5.0/gems/redis-4.1.3/lib/redis/client.rb | grep 123456
      :password => "123456",
