CentOS7安装配置redis-3.0.0

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
Installing ri 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.

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
