2.1 问题

部署新redis服务器
添加master角色主机到集群里
添加slave角色主机到集群里

2.2 步骤

实现此案例需要按照如下步骤进行。

步骤一：部署新redis服务器 ip为192.168.4.58

1）装包，初始化，启用集群功能，重启服务

]#yum -y  install gcc
]#tar -zxvf redis-4.0.8.tar.gz
]#cd redis-4.0.8/
]#make
]#make install
]#./utils/install_server.sh
]# /etc/init.d/redis_6379  stop
vim /etc/redis/6379.conf
        bind 192.168.4.58
        port 6358
        cluster-enabled  yes                         //启用集群
        cluster-config-file  nodes-6379.conf      //存储集群信息文件
        cluster-node-timeout  5000
:wq
]# vim +43 /etc/init.d/redis_6379
         $CLIEXEC -h 192.168.4.58 -p 6358 shutdown
:wq
]# /etc/init.d/redis_6379  start
]# netstat -utnlp  | grep redis-server
tcp  0  0 192.168.4.58:6358  0.0.0.0:*   LISTEN      21201/redis-server  
tcp  0  0 192.168.4.58:16358   0.0.0.0:*   LISTEN   21201/redis-server

步骤二：添加master角色主机到集群里

1）在管理主机，添加master角色主机

[root@mgm57 ~]# redis-trib.rb  add-node  192.168.4.58:6358  192.168.4.53:6353  //执行添加命令
>>> Adding node 192.168.4.58:6358 to cluster 192.168.4.53:6353
>>> Performing Cluster Check (using node 192.168.4.53:6353)

   slots:10923-16383 (5461 slots) master
   1 additional replica(s)
S: d9634ba0aa5c1a07193da4a013da6051c1515922 192.168.4.54:6354
   slots: (0 slots) slave
   replicates 9e44139cffb8ebd7ed746aabbf4bcea9bf207645
M: 324e05df3f143ef97e50d09be0328a695e655986 192.168.4.52:6352
   slots:5461-10922 (5462 slots) master
   1 additional replica(s)
S: 894dd0008053f6fb65e9e4a36b755d9351607500 192.168.4.56:6356
   slots: (0 slots) slave
   replicates 324e05df3f143ef97e50d09be0328a695e655986

   replicates 2d343a9df48f6f6e207949e980ef498466a44dad
M: 2d343a9df48f6f6e207949e980ef498466a44dad 192.168.4.55:6355
   slots:0-5460 (5461 slots) master
   1 additional replica(s)
[OK] All nodes agree about slots configuration.
>>> Check for open slots...
>>> Check slots coverage...
[OK] All 16384 slots covered.
>>> Send CLUSTER MEET to node 192.168.4.58:6358 to make it join the cluster.
[OK] New node added correctly. //提示添加完成
[root@mgm57 ~]#

2） 在管理主机，查看集群新消息

[root@mgm57 ~]# redis-trib.rb info 192.168.4.53:6353  //查看集群信息
192.168.4.53:6353 (9e44139c...) -> 3 keys | 5461 slots | 1 slaves.
192.168.4.52:6352 (324e05df...) -> 2 keys | 5462 slots | 1 slaves.
192.168.4.58:6358 (4fe1fa46...) -> 0 keys | 0 slots | 0 slaves. //主服务器58
192.168.4.55:6355 (2d343a9d...) -> 3 keys | 5461 slots | 1 slaves.
[OK] 8 keys in 4 masters.
0.00 keys per slot on average.
[root@mgm57 ~]#

3）在管理主机，检测集群

 [root@mgm57 ~]# redis-trib.rb check 192.168.4.53:6353    //检测集群
>>> Performing Cluster Check (using node 192.168.4.53:6353)
M: 9e44139cffb8ebd7ed746aabbf4bcea9bf207645 192.168.4.53:6353
   slots:10923-16383 (5461 slots) master
   1 additional replica(s)
S: d9634ba0aa5c1a07193da4a013da6051c1515922 192.168.4.54:6354
   slots: (0 slots) slave
   replicates 9e44139cffb8ebd7ed746aabbf4bcea9bf207645

   slots:5461-10922 (5462 slots) master
   1 additional replica(s)
S: 894dd0008053f6fb65e9e4a36b755d9351607500 192.168.4.56:6356
   slots: (0 slots) slave

   slots: (0 slots) master  //master服务器58 ，没有hash槽
   0 additional replica(s)
S: d9f8fe6d6d9dd391be8e7904501db1535e4d17cb 192.168.4.51:6351

   replicates 2d343a9df48f6f6e207949e980ef498466a44dad

   1 additional replica(s)
[OK] All nodes agree about slots configuration.
>>> Check for open slots...
>>> Check slots coverage...
[OK] All 16384 slots covered.
[root@mgm57 ~]#

4）在管理主机，重新分配hash槽

[root@mgm57 ~]# redis-trib.rb  reshard   192.168.4.53:6353  
How many slots do you want to move (from 1 to 16384)?4096   //拿出4096个hash 槽给主机192.168.4.58
What is the receiving node ID?  c5e0da48f335c46a2ec199faa99b830f537dd8a0   //主机192.168.4.58的id值
Source node #1:all      //从当前所有master服务器获取hash槽
Do you want to proceed with the proposed reshard plan (yes/no)?yes //同意以上配置
...
Moving slot 12283 from 192.168.4.53:6353 to 192.168.4.58:6358: 
Moving slot 12284 from 192.168.4.53:6353 to 192.168.4.58:6358: 
Moving slot 12285 from 192.168.4.53:6353 to 192.168.4.58:6358: 
Moving slot 12286 from 192.168.4.53:6353 to 192.168.4.58:6358: 
Moving slot 12287 from 192.168.4.53:6353 to 192.168.4.58:6358:

5）在管理主机，查看集群信息

[root@mgm57 ~]# redis-trib.rb info 192.168.4.53:6353
192.168.4.53:6353 (9e44139c...) -> 2 keys | 4096 slots | 1 slaves.
192.168.4.52:6352 (324e05df...) -> 1 keys | 4096 slots | 1 slaves.
192.168.4.58:6358 (4fe1fa46...) -> 4 keys | 4096 slots | 0 slaves. //hash槽4096个
192.168.4.55:6355 (2d343a9d...) -> 1 keys | 4096 slots | 1 slaves.
[OK] 8 keys in 4 masters.
0.00 keys per slot on average.
[root@mgm57 ~]#

步骤三：添加slave角色主机到集群里

1）部署新的redis服务器 192.168.4.59

]#yum -y  install gcc
]#tar -zxvf redis-4.0.8.tar.gz
]#cd redis-4.0.8/
]#make
]#make install
]#./utils/install_server.sh
]# /etc/init.d/redis_6379  stop
vim /etc/redis/6379.conf
        bind 192.168.4.59
        port 6359
        cluster-enabled  yes                         //启用集群
        cluster-config-file  nodes-6379.conf      //存储集群信息文件
        cluster-node-timeout  5000
:wq
]# vim +43 /etc/init.d/redis_6379
         $CLIEXEC -h 192.168.4.59 -p 6359 shutdown
:wq
]# /etc/init.d/redis_6379  start
]# netstat -utnlp  | grep redis-server
