redis cluster集群部署学习

1. 软件环境

ubuntu 14.04 64位

redis-3.2.4

ruby-1.9.1

下载redis，然后sudo make install

安装ruby sudo apt-get install ruby

sudo gem install redis（缺少这一步创建cluster的时候会报错）

hlbd@hlbd-android:~/javaweb/redis-3.2.4/src$ sudo gem install redis
Fetching: redis-3.3.1.gem (100%)
Successfully installed redis-3.3.1
1 gem installed
Installing ri documentation for redis-3.3.1...
Installing RDoc documentation for redis-3.3.1...

2. 本机用6个端口模拟6个redis

新建目录 clustertest

在此目录下新建6个子目录，分别为 server7000,server7001,server7002,server7003,server7004,server7005

在各自目录下新建data，log，run三个子目录，做为存放数据库，日志，和pid用

拷贝原始redis.conf文件到server7000下

编辑如下内容：

port 7000

daemonize yes

bind 127.0.0.1 192.168.31.33

protected-mode no

pidfile /home/hlbd/javaweb/redis-3.2.4/clustertest/server7000/run/redis_7000.pid

logfile /home/hlbd/javaweb/redis-3.2.4/clustertest/server7000/log/redis.log

cluster-enabled yes

cluster-config-file nodes-7000.conf

cluster-node-timeout 5000

appendonly yes

保存后，复制到server7001,server7002,sever7003,server7004,server7005目录下，并修改响应端口号和目录名

3. 启动6个redis

hlbd@hlbd-android:~/javaweb/redis-3.2.4/clustertest$ redis-server server7000/redis.conf

hlbd@hlbd-android:~/javaweb/redis-3.2.4/clustertest$ redis-server server7001/redis.conf

hlbd@hlbd-android:~/javaweb/redis-3.2.4/clustertest$ redis-server server7002/redis.conf

hlbd@hlbd-android:~/javaweb/redis-3.2.4/clustertest$ redis-server server7003/redis.conf

hlbd@hlbd-android:~/javaweb/redis-3.2.4/clustertest$ redis-server server7004/redis.conf

hlbd@hlbd-android:~/javaweb/redis-3.2.4/clustertest$ redis-server server7005/redis.conf

4.创建cluster

hlbd@hlbd-android:~/javaweb/redis-3.2.4/src$ ./redis-trib.rb create --replicas 1 192.168.31.33:7000 192.168.31.33:7001 192.168.31.33:7002 192.168.31.33:7003 192.168.31.33:7004 192.168.31.33:7005
replicas 1表示每个master创建1个slave

运行后输出如下:

>>> Creating cluster
