1 Redis Standalone安装
可以参考这篇博文：http://www.cnblogs.com/_popc/p/3684835.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
