redis集群启用了密码后ruby无法连接问题

环境:

os:Centos 7

redis:4.0.12

 

1. 查看ruby安装路径

[root@dev_test_redis ~]# which ruby
/opt/ruby/bin/ruby
[root@dev_test_redis ~]# 

 

2.尝试检查redis集群

检查其中一个节点即可

[root@dev_test_redis bin]# /usr/local/services/redis/redis-trib.rb check 192.168.1.84:6379
/opt/ruby/lib/ruby/gems/2.5.0/gems/redis-3.3.0/lib/redis/client.rb:459: warning: constant ::Fixnum is deprecated
[ERR] Sorry, can't connect to node 192.168.1.84:6379

 

3.解决办法

修改client.rb文件，填写密码部分

[root@dev_test_redis ruby]# find ./ -name client.rb
./lib/ruby/gems/2.5.0/gems/xmlrpc-0.3.0/lib/xmlrpc/client.rb
./lib/ruby/gems/2.5.0/gems/redis-3.3.0/lib/redis/client.rb

 

vi /opt/ruby/lib/ruby/gems/2.5.0/gems/redis-3.3.0/lib/redis/client.rb

[root@dev_test_redis ~]# more /opt/ruby/lib/ruby/gems/2.5.0/gems/redis-3.3.0/lib/redis/client.rb
require "redis/errors"
require "socket"
require "cgi"

class Redis
  class Client

    DEFAULTS = {
      :url => lambda { ENV["REDIS_URL"] },
      :scheme => "redis",
      :host => "127.0.0.1",
      :port => 6379,
      :path => nil,
      :timeout => 5.0,
      :password => "hxl2018",
      :db => 0,
      :driver => nil,
      :id => nil,
      :tcp_keepalive => 0,
      :reconnect_attempts => 1,
      :inherit_socket => false
    }

 

4.再次检查

[root@dev_test_redis redis]# /usr/local/services/redis/redis-trib.rb check 192.168.1.84:6379
/opt/ruby/lib/ruby/gems/2.5.0/gems/redis-3.3.0/lib/redis/client.rb:459: warning: constant ::Fixnum is deprecated
