一、準備六臺Redis服務器

準備源碼包redis-4.0.8.tar.gz

源碼編譯安裝

]# rpm -q gcc
]# yum -y install gcc
]# tar -zxf redis-4.0.8.tar.gz 
]# cd redis-4.0.8/
redis-4.0.8]# make && make install

初始化

使用默認配置

redis-4.0.8]# ./utils/install_server.sh 
Welcome to the redis service installer
This script will help you easily set up a running redis server

Please select the redis port for this instance: [6379] 
Selecting default: 6379
Please select the redis config file name [/etc/redis/6379.conf] 
Selected default - /etc/redis/6379.conf
Please select the redis log file name [/var/log/redis_6379.log] 
Selected default - /var/log/redis_6379.log
Please select the data directory for this instance [/var/lib/redis/6379] 
Selected default - /var/lib/redis/6379
Please select the redis executable path [/usr/local/bin/redis-server] 
Selected config:
Port           : 6379
Config file    : /etc/redis/6379.conf
Log file       : /var/log/redis_6379.log
Data dir       : /var/lib/redis/6379
Executable     : /usr/local/bin/redis-server
Cli Executable : /usr/local/bin/redis-cli
Is this ok? Then press ENTER to go on or Ctrl-C to abort.
Copied /tmp/6379.conf => /etc/init.d/redis_6379

二、創建集羣

2.1、啓用每臺redis服務器集羣功能

Redis1

[root@redis1 ~]# sed -n '70p;93p;815p;823p;829p' /etc/redis/6379.conf 
bind 192.168.4.51	//修改IP地址
port 6351			//定義端口號，集羣中多臺Redis服務器端口不能相同

三、測試集羣功能

停止master主機的redis服務
- master宕機後對應的slave自動被選舉爲master
- 原master啓動後，會自動配置爲當前master的slave

3.1、查看當前集羣狀態

[root@redismgm ~]# redis-trib.rb  check   192.168.4.53:6353
>>> Performing Cluster Check (using node 192.168.4.53:6353)

   slots:0-5460 (5461 slots) master
   1 additional replica(s)
[OK] All nodes agree about slots configuration.

3.2、停止51的服務

[root@redis1 ~]# redis-cli -h 192.168.4.51 -p 6351
192.168.4.51:6351> SHUTDOWN
not connected>

3.3、在查看集羣狀態

[root@redismgm ~]# redis-trib.rb  check   192.168.4.53:6353
>>> Performing Cluster Check (using node 192.168.4.53:6353)

   1 additional replica(s)
S: 5988a140790cb3e8c39e81acf1e585094656e0a2 192.168.4.54:6354

   slots: (0 slots) slave
   replicates 9e83ee6b3249077c63396b85f623fa12fe27dccc
[OK] All nodes agree about slots configuration.
>>> Check for open slots...
>>> Check slots coverage...
[OK] All 16384 slots covered.

3.4、插入幾條數據

192.168.4.52:6352> set a 401
-> Redirected to slot [15495] located at 192.168.4.53:6353
OK
192.168.4.53:6353> set b 501
-> Redirected to slot [3300] located at 192.168.4.55:6355
OK
192.168.4.55:6355> set c 601
-> Redirected to slot [7365] located at 192.168.4.52:6352
OK

3.5、重新將51服務啓動

[root@redis1 ~]# /etc/init.d/redis_6379 start
Starting Redis server...

3.6、51自動稱爲55的slave

[root@redismgm ~]# redis-trib.rb  check   192.168.4.53:6353
>>> Performing Cluster Check (using node 192.168.4.53:6353)

[OK] All 16384 slots covered

四、集羣管理

4.1、slave角色服務器移除和添加

登錄集羣服務器，移除55的從服務器51

[root@redismgm ~]# redis-trib.rb del-node 192.168.4.52:6352 c476e663fa6bf2e43ea7592edd74b3e143446d56
>>> Removing node c476e663fa6bf2e43ea7592edd74b3e143446d56 from cluster 192.168.4.52:6352
>>> Sending CLUSTER FORGET messages to the cluster...
>>> SHUTDOWN the node.

[root@redismgm ~]# redis-trib.rb  info  192.168.4.53:6353
192.168.4.53:6353 (13067f3c...) -> 5 keys | 5461 slots | 1 slaves.
192.168.4.52:6352 (9e83ee6b...) -> 2 keys | 5462 slots | 1 slaves.
192.168.4.55:6355 (2ecf108a...) -> 1 keys | 5461 slots | 0 slaves.

添加58做55的slave服務器

]#redis-trib.rb  add-node  --slave  [ --master-id  id值  ] ip地址:端口  192.168.4.51:635

移除master服務器

[root@redismgm ~]# redis-trib.rb reshard 192.168.4.51:6351
[root@redismgm ~]# redis-trib.rb del-node 192.168.4.51:6351 master主機id值
