一.安装必要包

yum install gcc

二.linux下安装

#下载

wget http://download.redis.io/releases/redis-3.0.0.tar.gz

tar zxvf redis-3.0.0.tar.gz

cd redis-3.0.0

#如果不加参数,linux下会报错

make MALLOC=libc

安装好之后,启动文件

#启动redis

src/redis-server &

#关闭redis

src/redis-cli shutdown

测试redis

$ src/redis-cli

127.0.0.1:6379> set foo bar

OK

127.0.0.1:6379> get foo

"bar"

$

测试成功

3.redis cluster集群搭建

建立本机测试环境

建立运行目录

#建立redis运行目录

mkdir -p redis-server/7000/

#复制默认的配置文档

cp redis-3.0.0/redis.conf redis-server/redis.default.conf

#把编译好的server复制到运行目录

cp redis-3.0.0/src/redis-server redis-server/7000/

建立独立配置文件

#在7000目录下建立redis的配置文档

vim redis-server/7000/redis.conf

文件内容

#redis-server/7000/redis.conf

include /root/redis-server/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

复制运行目录(模拟集群环境)

#复制目录

cp -R 7000/ 7001/

cp -R 7000/ 7002/

cp -R 7000/ 7003/

cp -R 7000/ 7004/

cp -R 7000/ 7005/

修改相应配置文件的端口和文件名

建立启动脚本 redis-server/redis-start.sh

#!/bin/sh

/root/redis-server/7000/redis-server /root/redis-server/7000/redis.conf &

/root/redis-server/7001/redis-server /root/redis-server/7001/redis.conf &

/root/redis-server/7002/redis-server /root/redis-server/7002/redis.conf &

/root/redis-server/7003/redis-server /root/redis-server/7003/redis.conf &

/root/redis-server/7004/redis-server /root/redis-server/7004/redis.conf &

/root/redis-server/7005/redis-server /root/redis-server/7005/redis.conf &

配置集群

安装ruby

yum install ruby-devel.x86_64

安装redis gem

# gem install redis

Fetching: redis-3.2.1.gem (100%)

Successfully installed redis-3.2.1

Parsing documentation for redis-3.2.1

1 gem installed

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

# ./redis-trib.rb create 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

[OK] All nodes agree about slots configuration.

>>> Check slots coverage...

[OK] All 16384 slots covered.

如果需要全部重新自动配置,则删除所有的配置好的cluster-config-file,重新启动所有的redis-server,然后重新执行配置命令即可
