• 節點ID

• IP:連接埠

• 標誌: master, slave, myself, fail, ...

• 如果是個從節點, 這裡是它的主節點的NODE ID

• 叢集最近一次向節點發送 PING 命令之後， 過去了多長時間還沒接到回複。.

• 節點最近一次返回 PONG 回複的時間。

• 節點的配置紀元（configuration epoch）：詳細資料請參考 Redis 叢集規範 。

• 本節點的網路連接情況：例如 connected 。

• 節點目前包含的槽：例如 127.0.0.1:7001 目前包含號碼為 5960 至 10921 的雜湊槽。

6385已經是主節點了，現在為他配置一個一從節點6387，另外在4這台主機上，如果從其他設定檔下複製redis-6387.conf時，注意有兩處地方要改，一是連接埠號碼6367，另外一個是 cluster-config-file nodes-6387.conf，不然執行redis-server redis-6387.conf會無法把進程連接埠啟動起來，查看日誌會出現如下報錯

[[email protected] redis]# cat /var/log/redis/redis-6387

12992:M 12 Jun 02:49:53.280 * Increased maximum number of open files to 10032 (it was originally set to 1024).

12992:M 12 Jun 02:49:53.281 # Sorry, the cluster configuration file nodes-6384.conf is already used by a different Redis Cluster node. Please make sure that different nodes use different cluster configuration files.

二、添加6387從節點

[[email protected] redis]# redis-cli -p 6387 cluster meet 192.168.1.3 6379

OK                            //執行這條命令預設是添主節點的，

[[email protected] redis]# redis-cli -h 192.168.1.3 -p 6379 cluster nodes

[[email protected] redis]# redis-cli -p 6387 cluster replicate dbc41c1e1a3c0c51c1e2a8216dace0f8883cf51f    

OK                                //CLUSTER REPLICATE 命令添加.這個命令也可以改變一個從節點的主節點。

 三在查看
