redis集群的搭建

redis集群的三种模式

主从复制
哨兵模式
cluster集群

redis-cluster集群的搭建（在一台linux中搭建,三主三从）

下载安装redis5.0.3

cd /opt 下载redis安装包 wget http://download.redis.io/releases/redis-5.0.3.tar.gz
tar -zxvf redis-5.0.3.tar.gz 解压
make 编译
cd redis-5.0.3/ 进入redis文件夹
mkdir -p /usr/local/redis-5.0.3 创建redis-5.0.3安装文件夹
make install PREFIX=/usr/local/redis-5.0.3 安装redis到/usr/local/redis-5.0.3

创建redis-cluster集群文件

mkdir -p /usr/local/redis-cluster 创建redis集群文件夹
cd /usr/local/
cp redis-5.0.3 ./redis-cluster -R 复制redis到集群目录中
分别创建config、log、run、dbfile目录
cd /usr/local/redis-cluster/redis-5.0.3
mkdir log
mkdir run
mkdir dbfile
mkdir -p config/6380
mkdir -p config/6381
mkdir -p config/6382
mkdir -p config/6383
mkdir -p config/6384
mkdir -p config/6385

修改redis.conf文件

cp /opt/redis-5.0.3/redis.conf /usr/local/redis-cluster/redis-5.0.3/conf/6380/6380.conf
找到并修改以下配置

bind 这里修改为本机的网卡ip protected-mode no daemonize yes appendonly yes port 6380 pidfile /usr/local/redis-cluster/redis-5.0.3/run/redis_6380.pid appendfilename "appendonly_6380.aof" logfile "/usr/local/redis-cluster/redis-5.0.3/log/redis_6380.log" requirepass password cluster-enabled yes cluster-node-timeout 5000 cluster-config-file nodes-6380.conf dbfilename dump_6380.rdb dir /usr/local/redis-cluster/redis-5.0.3/dbfile save 900 1 save 300 10 save 60 10000

复制该配置文件到其他的配置文件夹中，修改相应的配置（6380改为638？）

开启相应的端口（centos7端口默认关闭）

systemctl start firewalld 如果防火墙未开启，需要先开启
firewall-cmd –zone=public –add-port=6380/tcp –permanent 开启数据端口
firewall-cmd –zone=public –add-port=16380/tcp –permanent 开启总线端口数据端口和总线端口必须全部开启
其他相应端口同样开启
firewall-cmd –reload 重新载入配置
filewall-cmd –list-ports 查询已开放端口

开启redis服务

创建redis启动脚本
cd /usr/local/redis-cluster
vim startup.sh

#!/bin/bash /usr/local/redis-cluster/redis-5.0.3/bin/redis-server /usr/local/redis-cluster/redis-5.0.3/conf/6380/6380.conf /usr/local/redis-cluster/redis-5.0.3/bin/redis-server /usr/local/redis-cluster/redis-5.0.3/conf/6381/6381.conf /usr/local/redis-cluster/redis-5.0.3/bin/redis-server /usr/local/redis-cluster/redis-5.0.3/conf/6382/6382.conf /usr/local/redis-cluster/redis-5.0.3/bin/redis-server /usr/local/redis-cluster/redis-5.0.3/conf/6383/6383.conf /usr/local/redis-cluster/redis-5.0.3/bin/redis-server /usr/local/redis-cluster/redis-5.0.3/conf/6384/6384.conf /usr/local/redis-cluster/redis-5.0.3/bin/redis-server /usr/local/redis-cluster/redis-5.0.3/conf/6385/6385.conf

ps -ef|grep redis 查询redis是否开启

加入集群

cd /usr/local/redis-cluster/redis-5.0.3/bin ./redis-cli -a password --cluster create 192.168.75.101:6380 192.168.75.101:6381 192.168.75.101:6382 192.168.75.101:6383 192.168.75.101:6384 192.168.75.101:6385 --cluster-replicas 1
