在執行:

redis-trib.rb create --replicas 1 ........

提示:>>> Creating cluster
[ERR] Sorry, can’t connect to node ip:port
解決方案:

find / -name client.rb -print

/usr/share/ruby/xmlrpc/client.rb
/usr/local/lib/ruby/2.3.0/xmlrpc/client.rb
/usr/local/lib/ruby/2.1.0/xmlrpc/client.rb
/usr/local/rvm/src/ruby-2.3.3/lib/xmlrpc/client.rb
/usr/local/rvm/gems/ruby-2.3.3/gems/redis-4.0.0/lib/redis/client.rb
/usr/local/rvm/rubies/ruby-2.3.3/lib/ruby/2.3.0/xmlrpc/client.rb

找到gems目錄下的client.rb,並修改它(在執行redis-trib.rb的機器上修改就可以了):

vim /usr/local/rvm/gems/ruby-2.3.3/gems/redis-4.0.0/lib/redis/client.rb

一下配置,根據自己環境來配置,比如:我的埠和密碼

    DEFAULTS = {
      :url => lambda { ENV["REDIS_URL"] },
      :scheme => "redis",
      :host => "127.0.0.1",
      :port => 6377,
      :path
 
 => nil,
      :timeout => 5.0,
      :password => "Htdhy,Lyzhh",
      :db => 0,
      :driver => nil,
      :id => nil,
      :tcp_keepalive => 0,
      :reconnect_attempts => 1,
      :inherit_socket => false
    }

儲存,重新執行

redis-trib.rb create --replicas 1 ........
