Redis Cluster部署

一、机器规划

机器 IP	节点角色	端口
192.168.71.149	主节点 1、从节点 2	7000、7001
192.168.71.172	主节点 2、从节点 3	7000、7001
192.168.71.173	主节点 3、从节点 1	7000、7001

redis版本：redis-7.0.15

二、部署（三台节点统一执行）

1. 安装依赖并编译 Redis

yum install -y gcc make wget

tar -zxvf redis-7.0.15.tar.gz -C /opt

cd  /opt/redis-7.0.15

make && make install

2. 创建节点目录

mkdir -p /data/redis-cluster/{7000,7001}

3. 配置文件

cat > /data/redis-cluster/7000/redis.conf << EOF
port 7000
daemonize yes
dir /data/redis-cluster/7000
logfile /data/redis-cluster/7000/redis.log
dbfilename dump.rdb
appendonly yes
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
protected-mode no
bind 0.0.0.0
requirepass Hybridcloud2025 
masterauth Hybridcloud2025
EOF

cat > /data/redis-cluster/7001/redis.conf << EOF
port 7001
daemonize yes
dir /data/redis-cluster/7001
logfile /data/redis-cluster/7001/redis.log
dbfilename dump.rdb
appendonly yes
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
protected-mode no
bind 0.0.0.0
requirepass Hybridcloud2025 
masterauth Hybridcloud2025
EOF

4. 启动节点

redis-server /data/redis-cluster/7000/redis.conf

redis-server /data/redis-cluster/7001/redis.conf

# 检查是否启动

ps -ef | grep redis

 三、任意一台机器执行：创建集群

redis-cli --cluster create \
192.168.71.149:7000 \
192.168.71.172:7000 \
192.168.71.173:7000 \
192.168.71.149:7001 \
192.168.71.172:7001 \
192.168.71.173:7001 \
--cluster-replicas 1 \
-a Hybridcloud2025

# 执行后，看到 Can I set the above configuration? 时，输入 yes 回车

# 验证集群

redis-cli -c -h 192.168.71.149 -p 7000 -a Hybridcloud2025 cluster nodes

# 关闭集群节点

redis-cli -p 7000 -a Hybridcloud2025 shutdown

redis-cli -p 7001 -a Hybridcloud2025 shutdown
