redis3.2.4 集群安装详细步骤

本文主要是介绍redis3.2.4 集群安装详细步骤，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

集群简介

Redis集群部署文档(centos6.4系统)
（要让集群正常工作至少需要3个主节点，在这里我们要创建6个redis节点，其中三个为主节点，三个为从节点，对应的redis节点的ip和端口对应关系如下）

192.168.66.2:6379
192.168.66.2:6380
192.168.66.3:6379
192.168.66.3:6380
192.168.66.4:6379
192.168.66.5:6380

软件下载安装

下载redis：官网下载3.2.4版本。
- 3.2.4 下载地址
- 其它版本下载地址

上传服务器、解压、编译

解压编译

tar -zxvf redis-3.2.4-rc2.tar.gz 
mv redis-3.2.4-rc2.tar.gz redis3.0
cd /usr/local/redis3.0
make
make install# 复制 redis-trib.rb 到 /usr/local/bincp /opt/tools/redis-3.2.4/src/redis-trib.rb /usr/local/bin/

报错解决

yum install -y gcc g++ gcc-c++

创建所需要的目录

cd /opt/tools/
mkdir redis-cluster
cd redis-cluster
mkdir 6379
mkdir 6380

修改配置文件：

复制 redis.conf 文件

cp redis-3.2.4/redis.conf redis-cluster/6379

修改文件的如下内容：


#进程端口port 6379#进程id文件存放位置pidfile /var/run/redis-6379.pid#绑定机器配置bind 192.168.66.2#日志文件存放位置logfile /opt/tools/redis-cluster/6379/redis.log#数据备份文件存放位置dir /opt/tools/redis-cluster/6379#是否是追加appendonly yes#是否开启分布式cluster-enabled yes#集群配置文件cluster-config-file /opt/tools/redis-cluster/6379/nodes.conf

拷贝文件到其他几台机器


# 拷贝redis-server、redis-client...scp -r /usr/local/bin/* root@192.168.66.3:/usr/local/bin/# 拷贝配置文件scp -r /opt/tools/redis-cluster root@192.168.66.3:/opt/tools/# 拷贝redis-server、redis-client...scp -r /usr/local/bin/* root@192.168.66.4:/usr/local/bin/# 拷贝配置文件scp -r /opt/tools/redis-cluster root@192.168.66.4:/opt/tools/

编写集群启动脚本redisStart.sh（集群启动脚本需要各个机器之间设置 ssh 免认证登录）


#!/bin/bash
#声明服务器：server2=192.168.66.2
