redis 集群配置

①，查看gcc是否安装

gcc -v

没有就安装gcc

yum install gcc

②加压redis文件并安装

解压 tar -zxvf redis-xxx.tar.gz

进入 cd redis-3.0.6

键入 make 进行安装

将 redis-cli，redis-sentinel，redis-server 放入/usr/local/bin

这样在任意目录下就能启动redis了

③新建redis_cluster 目录

在redis_cluster 目录下新建 7001,7002,7003,7004,7005,7006文件夹

cp redis.conf /redis_cluster/redis7001.conf

vim redis7001.conf

修改如下：

daemonize yes #后台启动

port 700x #修改端口号，从7001到7006

cluster-enabled yes #开启cluster，去掉注释

cluster-config-file nodes.conf

cluster-node-timeout 15000

appendonly yes

dir /redis-3.0.6/redis_cluster/700x #修改目录，从7001到7006

bind 127.0.0.1

④redis-server redis700x.conf 启动对应的redis

ps -ef|grep redis 若能看到下图，说明前面配置成功

[root@localhost src]# ps -ef|grep redis
root 2304 1 0 20:08 ? 00:00:01 redis-server 127.0.0.1:7002 [cluster]
root 2328 1 0 20:15 ? 00:00:01 redis-server 127.0.0.1:7001 [cluster]
root 2334 1 0 20:15 ? 00:00:01 redis-server 127.0.0.1:7003 [cluster]
root 2341 1 0 20:15 ? 00:00:01 redis-server 127.0.0.1:7004 [cluster]
root 2349 1 0 20:17 ? 00:00:01 redis-server 127.0.0.1:7006 [cluster]
root 2355 1 0 20:17 ? 00:00:00 redis-server 127.0.0.1:7005 [cluster]
root 4576 2272 0 20:47 pts/0 00:00:00 grep redis

⑤ 安装ruby环境：

yum install ruby

yum install rubygems

下载redis-3.2.2.gem（可以到这篇博客里下载）

放入 redis_cluster目录，执行如下命令

gem install redis-3.2.2.gem

⑥使用redis-trib.rb创建集群

./redis-trib.rb create --replicas 1 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005 127.0.0.1:7006
看到如下情况，表示成功

[root@localhost src]# ./redis-trib.rb create --replicas 1 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005 127.0.0.1:7006

⑦连接redis集群客户端

[root@localhost redis01]# ./redis-cli -c -p 7001
127.0.0.1:7001> set name andy
-> Redirected to slot [5798] located at 127.0.0.1:7002
OK
127.0.0.1:7002> get name
"andy"
127.0.0.1:7002>
