Redis集群

1.在opt/redis-7.0.10下 mkdir redisCluster文件目录

cp redis.conf redisCluster

2.vim redis6379.conf

创建6379 6380 6381 6389 6390 6391 六个结点的配置文件

cp redis6379.conf redis6380.conf? ? ........

include /root/myredis/redis.conf
port 6379
pidfile "/var/run/redis_6379.pid"
dbfilename "dump6379.rdb"
cluster-enabled yes
cluster-config-file nodes-6379.conf
cluster-node-timeout 15000

修改每个配置文件中的内容

3.添加脚本命令:touch start.sh

#!/bin/sh
redis-server redis6379.conf &
redis-server redis6380.conf &
redis-server redis6381.conf &
redis-server redis6389.conf &
redis-server redis6390.conf &
redis-server redis6391.conf &
?要求:redis6379名称要与创建的配置文件名称一致

4.关闭脚本vim shutdown.sh

#!/bin/sh
redis-cli -p 6379 shutdown &
redis-cli -p 6380 shutdown &
redis-cli -p 6381 shutdown &
redis-cli -p 6389 shutdown &
redis-cli -p 6390 shutdown &
redis-cli -p 6391 shutdown &

5.执行脚本

#启动redis
sh start.sh ??

#关闭redis
sh shutdown.sh

6.启动6 个服务

[root@localhost redisCluster]# redis-server redis6379.conf
[root@localhost redisCluster]# redis-server redis6380.conf
[root@localhost redisCluster]# redis-server redis6381.conf
[root@localhost redisCluster]# redis-server redis6389.conf
[root@localhost redisCluster]# redis-server redis6390.conf
[root@localhost redisCluster]# redis-server redis6391.conf
[root@localhost redisCluster]# ps -ef | grep redis
root ? ? ?13471 ?10062 ?0 17:57 pts/1 ? ?00:00:00 cp -i redis.conf redisCluster
root ? ? ?13813 ? ? ?1 ?0 18:11 ? ? ? ? ?00:00:00 redis-server *:6379 [cluster]
root ? ? ?13814 ? ? ?1 ?0 18:11 ? ? ? ? ?00:00:00 redis-server *:6380 [cluster]
root ? ? ?13815 ? ? ?1 ?0 18:11 ? ? ? ? ?00:00:00 redis-server *:6391 [cluster]
root ? ? ?13816 ? ? ?1 ?0 18:11 ? ? ? ? ?00:00:00 redis-server *:6381 [cluster]
root ? ? ?13817 ? ? ?1 ?0 18:11 ? ? ? ? ?00:00:00 redis-server *:6389 [cluster]
root ? ? ?13818 ? ? ?1 ?0 18:11 ? ? ? ? ?00:00:00 redis-server *:6390 [cluster]
root ? ? ?13987 ?10062 ?0 18:20 pts/1 ? ?00:00:00 grep --color=auto redis
?

切换到opt/redis-7.0.10/src

运行

redis-cli --cluster create --cluster-replicas 1 192.168.126.128:6379 192.168.126.128:6380 192.168.126.128:6381 192.168.126.128:6389 192.168.126.128:6390 192.168.126.128:6391

7.登录查看

[root@localhost /]# redis-cli -c -p 6379

登录指令添加 -c 代表以集群方式登录

8.查看集群信息

192.168.126.128:6381> CLUSTER NODES
