Ubuntu 15.10 下Redis Cluster使用

1 Redis Standalone安装

可以参考这篇博文：/article/5273716.html

2 Redis Cluster安装

2.1 环境介绍：

Ubuntu 15.10，9台电脑，3 master，6 slave

2.2 环境准备：

安装ruby

sudo apt-get install ruby

安装Redis Ruby驱动

sudo gem install redis

2.3 修改配置文件

通用配置文件：redis-common.conf

#GENERAL
daemonize yes
tcp-backlog 511
timeout 0
tcp-keepalive 0
loglevel notice
databases 16
logfile "/home/hadoop/software/cloud/redis-3.0.4/data/redis/redis.log"
dir /home/hadoop/software/cloud/redis-3.0.4/working_directory
slave-serve-stale-data yes
#slave只读
slave-read-only yes
#not use default
repl-disable-tcp-nodelay yes
slave-priority 100
#打开aof持久化
appendonly yes
#每秒一次aof写
appendfsync everysec
#关闭在aof rewrite的时候对新的写操作进行fsync
no-appendfsync-on-rewrite yes
auto-aof-rewrite-min-size 64mb
lua-time-limit 5000
#打开redis集群
cluster-enabled yes
#节点互连超时的阀值
cluster-node-timeout 15000
cluster-migration-barrier 1
slowlog-log-slower-than 10000
slowlog-max-len 128
notify-keyspace-events ""
hash-max-ziplist-entries 512
hash-max-ziplist-value 64
list-max-ziplist-entries 512
list-max-ziplist-value 64
set-max-intset-entries 512
zset-max-ziplist-entries 128
zset-max-ziplist-value 64
activerehashing yes
client-output-buffer-limit normal 0 0 0
client-output-buffer-limit slave 256mb 64mb 60
client-output-buffer-limit pubsub 32mb 8mb 60
hz 10
aof-rewrite-incremental-fsync yes

个性化配置文件：redis-6379.conf

#包含通用配置
include /home/hadoop/software/cloud/redis-3.0.4/redis-common.conf
#监听tcp端口
port 6379
#最大可用内存
maxmemory 10240m
#内存耗尽时采用的淘汰策略:
# volatile-lru -> remove the key with an expire set using an LRU algorithm
# allkeys-lru -> remove any key accordingly to the LRU algorithm
# volatile-random -> remove a random key with an expire set
# allkeys-random -> remove a random key, any key
# volatile-ttl -> remove the key with the nearest expire time (minor TTL)
# noeviction -> don't expire at all, just return an error on write operations
maxmemory-policy allkeys-lru
#aof存储文件
appendfilename "appendonly-6379.aof"
#rdb文件,只用于动态添加slave过程
dbfilename dump-6379.rdb
#cluster配置文件(启动自动生成)
cluster-config-file nodes-6379.conf
#部署在同一机器的redis实例，把auto-aof-rewrite搓开，防止瞬间fork所有redis进程做rewrite,占用大量内存
auto-aof-rewrite-percentage 80-100

2.4 每台机器启动redis-server

redis-server redis-6379.conf

2.5 创建集群

src/redis-trib.rb create --replicas 2 192.168.1.100:6379 192.168.1.101:6379 192.168.1.106:6379 192.168.1.107:6379 192.168.1.108:6379

192.168.1.109:6379 192.168.1.103:6379 192.168.1.104:6379 192.168.1.105:6379

2.6 进入Redis命令行测试

redis-cli -c -p 6379

3 Redis Cluster 命令
