環境搭建

- node1上操作（分別進行以下操作）

[root@node1 ~]# mkdir cluster
[root@node1 ~]# cd cluster/
[root@node1 cluster]# mkdir node1
[root@node1 cluster]# mkdir node2
[root@node1 cluster]# mkdir node3
[root@node1 cluster]# ls
node1  node2  node3
[root@node1 ~]# tar -zxvf redis-4.0.8.tar.gz -C cluster/node1/
[root@node1 ~]# tar -zxvf redis-4.0.8.tar.gz -C cluster/node2/
[root@node1 ~]# tar -zxvf redis-4.0.8.tar.gz -C cluster/node3/
[root@node1 ~]# cd cluster/node1/redis-4.0.8/
[root@node1 redis-4.0.8]# make 
[root@node1 redis-4.0.8]# make install
[root@node1 redis-4.0.8]# ./utils/install_server.sh
##指定你的配置，本次安裝指定的是6377端口

注：如果想設置密碼，可以到配置文件中配置。比如你的數據庫設置的密碼爲123456

[root@node1 ~]# find / -name "client.rb"
/usr/local/share/gems/gems/redis-3.2.1/lib/redis/client.rb
[root@node1 ~]# vim /usr/local/share/gems/gems/redis-3.2.1/lib/redis/client.rb
class Redis
  class Client

    DEFAULTS = {
      :url => lambda { ENV["REDIS_URL"] },
      :scheme => "redis",
      :host => "127.0.0.1",
      :port => 6379,
      :path => nil,
      :timeout => 5.0,
      :connect_timeout => 5.0,
      :password => 123456,
      :db => 0,
      :driver => nil,
      :id => nil,
      :tcp_keepalive => 0,
      :reconnect_attempts => 1,
      :inherit_socket => false
    }

需把文件中的密碼改爲123456，如上所述。
