如何创建redis集群

1.Download

wget http://download.redis.io/releases/redis-5.0.5.tar.gz
or
curl -o http://download.redis.io/releases/redis-5.0.5.tar.gz

 

2.Compile

On linux: make MALLOC=libc
On Mac: make MALLOC=jemalloc

 

3.Install

make install

 

4.Configuration

(3 Master and 3 Slave nodes)

port 7000(-7005)
bind 192.168.133.130
daemonize yes
pidfile /var/run/redis_7000.pid
dir /data/redis_data/7000
cluster-enabled yes
cluster-config-file nodes_7000.conf
cluster-node-timeout 10100
appendonly yes

5.Start Server

On Master Node:
/usr/local/bin/redis-server redis01.conf
/usr/local/bin/redis-server redis03.conf
/usr/local/bin/redis-server redis05.conf

On Slave Node:
/usr/local/bin/redis-server redis02.conf
/usr/local/bin/redis-server redis04.conf
/usr/local/bin/redis-server redis06.conf

6.Create Cluster

On 4.x:
redis-trib.rb create --replicas 1 192.168.133.130:7000 192.168.133.130:7002 192.168.133.130:7004 192.168.133.132:7001 192.168.133.132:7003 192.168.133.132:7005

On 5.x:
redis-cli --cluster create 192.168.133.130:7000 192.168.133.130:7002 192.168.133.130:7004 192.168.133.132:7001 192.168.133.132:7003 192.168.133.132:7005 --cluster-replicas 1

 

7.Manage Cluster

192.168.133.130:7000> CLUSTER HELP
1) CLUSTER <subcommand> arg arg ... arg. Subcommands are:
2) ADDSLOTS <slot> [slot ...] -- Assign slots to current node.
3) BUMPEPOCH -- Advance the cluster config epoch.
4) COUNT-failure-reports <node-id> -- Return number of failure reports for <node-id>.
5) COUNTKEYSINSLOT <slot> - Return the number of keys in <slot>.
6) DELSLOTS <slot> [slot ...] -- Delete slots information from current node.
7) FAILOVER [force|takeover] -- Promote current replica node to being a master.
8) FORGET <node-id> -- Remove a node from the cluster.
9) GETKEYSINSLOT <slot> <count> -- Return key names stored by current node in a slot.
10) FLUSHSLOTS -- Delete current node own slots information.
11) INFO - Return onformation about the cluster.
12) KEYSLOT <key> -- Return the hash slot for <key>.
13) MEET <ip> <port> [bus-port] -- Connect nodes into a working cluster.
14) MYID -- Return the node id.
15) NODES -- Return cluster configuration seen by node. Output format:
16) <id> <ip:port> <flags> <master> <pings> <pongs> <epoch> <link> <slot> ... <slot>
17) REPLICATE <node-id> -- Configure current node as replica to <node-id>.
18) RESET [hard|soft] -- Reset current node (default: soft).
19) SET-config-epoch <epoch> - Set config epoch of current node.
20) SETSLOT <slot> (importing|migrating|stable|node <node-id>) -- Set slot state.
21) REPLICAS <node-id> -- Return <node-id> replicas.
22) SLOTS -- Return information about slots range mappings. Each range is made of:
23) start, end, master and replicas IP addresses, ports and ids

shutdown cluster:
