Redis-Cluster 集群搭建（三主三从）

搭建Ruby

yum install ruby
yum install rubygems

安装redis 和 gcc,tcl

// 坑说明 ：
// redis集群创建执行
/*一直等待 Waiting for the cluster to join 很久都没有反应
/*原因：
/*redis集群不仅需要开通redis客户端连接的端口，而且需要开通集群总线端口
/*集群总线端口为redis客户端连接的端口 + 10000
/*如redis端口为6379
/*则集群总线端口为16379
/*故，所有服务器的点需要开通redis的客户端连接端口和集群总线端口
/*注意：iptables 放开，如果有安全组，也要放开这两个端口*/

如上配置完毕，接下来测试：

// 说明，不加 -c set 值等会报错。注意这个坑。
[root@bogon redis-cluster]# ./redis-cli -h 192.168.25.153 -p 7002 -c

给集群设置密码：

//说明 ： 所有节点的配置文件redis.conf 中 的 # requirepass foobared  和  masterauth foobared  必须设置为一样。

//第二 修改 client.rb 中的密码 和 上面的密码一样 。 client.rb 是 gem install redis-3.0.0.gem 安装后的产物
[root@iZ2ze9nu4bhzqni394evcsZ bin]# find / -name "client.rb"
/usr/share/ruby/xmlrpc/client.rb
/usr/local/share/gems/gems/redis-3.0.0/lib/redis/client.rb
[root@iZ2ze9nu4bhzqni394evcsZ bin]# vim /usr/local/share/gems/gems/redis-3.0.0/lib/redis/client.rb

class Redis
  class Client

    DEFAULTS = {
      :scheme => "redis",
      :host => "127.0.0.1",
      :port => 6379,
      :path => nil,
      :timeout => 5.0,
      :password => "43jd6fd",
      :db => 0,
    }
......................省略。

修改如上密码 和 redis.conf 密码一致。从启 6个节点的服务即可。

测试：

E:\redis>redis-cli.exe -h 39.134.231 -p 7001 -a 43jnrwed6fd -c
39.107.234.231:7001> set agui guige
-> Redirected to slot [15294] located at 120.79.246.84:7001
OK
120.79.246.84:7001> get agui
"guige"
120.79.246.84:7001> ^C
E:\redis>redis-cli.exe -h 39.107.234.231 -p 7001 -c

39.107.234.231:7001> get agui
(error) NOAUTH Authentication required.
39.107.234.231:7001> ^C

注意：客户端连接的时候，要加 -c ,否则无法对redis 集群操作。通过以上也可以看出，redis 设置密码成功。不通过密码连接会进行身份的验证。
