Redis 集群部署

1.安装redis 3.0.1，参见《Redis 3.0.1 安装和配置》Redis 3.0.1 安装和配置

2.创建目录

1	mkdir -p /usr/local/redis/7000

3.复制文件

1 2 3 4 5

cd /tmp #复制默认的配置文档 cp redis-3.0.1/redis.conf /usr/local/redis/redis.default.conf #把编译好的server复制到运行目录 cp redis-3.0.1/src/redis-server /usr/local/redis/7000/

4.建立独立配置文件

1 2	#在7000目录下建立redis的配置文档 vim /usr/local/redis/7000/redis.conf

1 2 3 4 5 6 7 8

#/usr/local/redis/7000/redis.conf include /usr/local/redis/redis.default.conf pidfile /var/run/redis-7000.pid port 7000 cluster-enabled yes cluster-config-file redis-node-7000.conf cluster-node-timeout 5000 appendonly yes

5.复制运行目录

1 2 3 4 5 6

cd /usr/local/redis/ cp -R 7000/ 7001/ cp -R 7000/ 7002/ cp -R 7000/ 7003/ cp -R 7000/ 7004/ cp -R 7000/ 7005/

6.修改相应配置文件的端口和文件名

7.建立启动脚本/usr/local/redis/redis-start.sh

1 2 3 4 5 6 7

#!/bin/sh /usr/local/redis/7000/redis-server /usr/local/redis/7000/redis.conf & /usr/local/redis/7001/redis-server /usr/local/redis/7001/redis.conf & /usr/local/redis/7002/redis-server /usr/local/redis/7002/redis.conf & /usr/local/redis/7003/redis-server /usr/local/redis/7003/redis.conf & /usr/local/redis/7004/redis-server /usr/local/redis/7004/redis.conf & /usr/local/redis/7005/redis-server /usr/local/redis/7005/redis.conf &

8.添加执行权限

1	chmod a+x redis-start.sh

9.启动六个redis实例

1	./redis-start.sh

配置集群

1.安装ruby

1	yum install ruby-devel.x86_64

2.安装redis gem

1	gem install redis

3.使用脚本建立集群机制
在create的时候,加上参数--replicas 1 表示为每个master分配一个salve,如例子,则是3个master 3个salve

1 2	cd /tmp/redis-3.0.1/src/ ./redis-trib.rb create --replicas 1 127.0.0.1:7000 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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66
