一、集群规格

二、安装redis-5.0.14集群

1.下载地址redis-5.0.14

2.上传包到每台服务器解压编译安装

tar -xvf redis-5.0.14.tar.gz
cd redis-5.0.14
make PREFIX=/usr/local/redis install

3.创建相关目录，编辑配置文件（在每台服务器上创建，也可以在一台上创建后拷贝到其他节点,我这里选择创建好一台后拷贝到其他节点）

mkdir -p /data/redis_cluster/{7001,7002}/{data,logs}

vi /data/redis_cluster/7001/redis_7001.conf

bind 10.0.0.108
daemonize yes

vi /usr/lib/systemd/system/redis_7001.service

[Unit]
Description=Redis
After=network.target

[Service]
Type=forking
ExecStart=/usr/local/redis/bin/redis-server /data/redis_cluster/7001/redis_7001.conf
PrivateTmp=true
RemainAfterExit=yes

[Install]

vi /usr/lib/systemd/system/redis_7002.service

[Unit]

[Service]

4.拷贝文件到其他节点

在10.0.0。108上执行
scp -r /data/redis_cluster/ [email protected]:/data/
scp -r /data/redis_cluster/ [email protected]:/data/
注意修改redis_7001.conf和redis_7002.conf中bind的IP

scp /usr/lib/systemd/system/redis_7001.service [email protected]:/usr/lib/systemd/system/redis_7001.service
scp /usr/lib/systemd/system/redis_7002.service [email protected]:/usr/lib/systemd/system/redis_7002.service
scp /usr/lib/systemd/system/redis_7001.service [email protected]:/usr/lib/systemd/system/redis_7001.service
scp /usr/lib/systemd/system/redis_7002.service [email protected]:/usr/lib/systemd/system/redis_7002.service

三、启动所有节点的redis服务

systemctl start redis_7001.service
systemctl start redis_7002.service
systemctl enable redis_7001.service
systemctl enable redis_7002.service

四、创建redis集群

cp /usr/local/redis/bin/redis-cli /usr/bin/
redis-cli -a 123456 --cluster create --cluster-replicas 1 10.0.0.108:7001 10.0.0.108:7002 10.0.0.109:7001 10.0.0.109:7002 10.0.0.110:7001 10.0.0.110:7002
执行命令后会让你确认配置，输入yes确认

五、连接集群验证

redis-cli -a 123456 -c -h 10.0.0.108 -p 7001
