部署Redis Cluster集群

1.先在虚拟机上安装redis

cd /usr/local wget https://download.redis.io/releases/redis-6.2.18.tar.gz tar -zxvf redis-6.2.18.tar.gz cd redis-6.2.18 make && make install

2.创建目录

mkdir -p /redis-cluster/{7001,7002,7003,7004,7005,7006}

3.部署节点

cat > /redis-cluster/7001/redis.conf <<EOF bind 0.0.0.0 port 7001 daemonize yes pidfile /var/run/redis_7001.pid logfile /redis-cluster/7001/redis.log dir /redis-cluster/7001 cluster-enabled yes cluster-config-file nodes-7001.conf cluster-node-timeout 5000 appendonly yes protected-mode no EOF

cat > /redis-cluster/7002/redis.conf <<EOF bind 0.0.0.0 port 7002 daemonize yes pidfile /var/run/redis_7002.pid logfile /redis-cluster/7002/redis.log dir /redis-cluster/7002 cluster-enabled yes cluster-config-file nodes-7002.conf cluster-node-timeout 5000 appendonly yes protected-mode no EOF

cat > /redis-cluster/7003/redis.conf <<EOF bind 0.0.0.0 port 7003 daemonize yes pidfile /var/run/redis_7003.pid logfile /redis-cluster/7003/redis.log dir /redis-cluster/7003 cluster-enabled yes cluster-config-file nodes-7003.conf cluster-node-timeout 5000 appendonly yes protected-mode no EOF

cat > /redis-cluster/7004/redis.conf <<EOF bind 0.0.0.0 port 7004 daemonize yes pidfile /var/run/redis_7004.pid logfile /redis-cluster/7004/redis.log dir /redis-cluster/7004 cluster-enabled yes cluster-config-file nodes-7004.conf cluster-node-timeout 5000 appendonly yes protected-mode no EOF

cat > /redis-cluster/7005/redis.conf <<EOF bind 0.0.0.0 port 7005 daemonize yes pidfile /var/run/redis_7005.pid logfile /redis-cluster/7005/redis.log dir /redis-cluster/7005 cluster-enabled yes cluster-config-file nodes-7005.conf cluster-node-timeout 5000 appendonly yes protected-mode no EOF

cat > /redis-cluster/7006/redis.conf <<EOF bind 0.0.0.0 port 7006 daemonize yes pidfile /var/run/redis_7006.pid logfile /redis-cluster/7006/redis.log dir /redis-cluster/7006 cluster-enabled yes cluster-config-file nodes-7006.conf cluster-node-timeout 5000 appendonly yes protected-mode no EOF

4.逐个启动

redis-server /redis-cluster/7001/redis.conf redis-server /redis-cluster/7002/redis.conf redis-server /redis-cluster/7003/redis.conf redis-server /redis-cluster/7004/redis.conf redis-server /redis-cluster/7005/redis.conf redis-server /redis-cluster/7006/redis.conf

5.启动后，检查进程是否存在

ps -ef | grep redis-server

6.部署集群（等待后输入yes）

redis-cli --cluster create \ 192.168.199.115:7001 \ 192.168.199.115:7002 \ 192.168.199.115:7003 \ 192.168.199.115:7004 \ 192.168.199.115:7005 \ 192.168.199.115:7006 \ --cluster-replicas 1

7.验证集群

redis-cli -c -h 192.168.199.115 -p 7001 cluster info

从图可看出是 3 主 3 从结构

8.关闭集群

建议在关闭虚拟机前，先执行

redis-cli -c -h 192.168.199.115 -p 7001 shutdown redis-cli -c -h 192.168.199.115 -p 7002 shutdown redis-cli -c -h 192.168.199.115 -p 7003 shutdown redis-cli -c -h 192.168.199.115 -p 7004 shutdown redis-cli -c -h 192.168.199.115 -p 7005 shutdown redis-cli -c -h 192.168.199.115 -p 7006 shutdown

9.再重新启动执行第四步即可

10.删除集群

1.先关闭所有节点进程，步骤八

2.再删除集群目录和相关文件

# 删除整个集群目录 rm -rf /redis-cluster # 删除可能残留的pid文件 rm -f /var/run/redis_700*.pid

3.清理日志和持久化文件（可选）

# 清理日志（如果日志路径在别处） rm -f /var/log/redis_*.log # 清理持久化文件（如果dir配置在别处） rm -f /var/lib/redis/*.rdb /var/lib/redis/*.aof

11.要想能让自己连接上，还要在部署完成后输入以下指令（开放防火墙端口）

firewall-cmd --permanent --add-port=7001-7006/tcp firewall-cmd --permanent --add-port=17001-17006/tcp firewall-cmd --reload

用docker部署Redis集群

有问题docker不能用参考：https://blog.csdn.net/2302_80248454/article/details/158775162?fromshare=blogdetail&sharetype=blogdetail&sharerId=158775162&sharerefer=PC&sharesource=2402_85101298&sharefrom=from_link

1.创建目录

mkdir -p /opt/redis-cluster/{node1,node2,node3,node4,node5,node6} cd /opt/redis-cluster

2.为每个节点创建配置文件

cat > node1/redis.conf << EOF port 7001 cluster-enabled yes cluster-config-file nodes.conf cluster-node-timeout 5000 appendonly yes protected-mode no daemonize no bind 0.0.0.0 EOF

for i in {2..6}; do sed "s/7001/700$i/" node1/redis.conf > node$i/redis.conf done

3.编写`docker-compose.yaml`文件

vi docker-compose.yaml

version: '3.8' services: redis-node1: image: redis:7 container_name: redis-node1 ports: - "7001:7001" - "17001:17001" volumes: - ./node1/redis.conf:/etc/redis/redis.conf - ./node1/data:/data command: redis-server /etc/redis/redis.conf networks: redis-cluster-net: ipv4_address: 172.20.0.2 redis-node2: image: redis:7 container_name: redis-node2 ports: - "7002:7002" - "17002:17002" volumes: - ./node2/redis.conf:/etc/redis/redis.conf - ./node2/data:/data command: redis-server /etc/redis/redis.conf networks: redis-cluster-net: ipv4_address: 172.20.0.3 redis-node3: image: redis:7 container_name: redis-node3 ports: - "7003:7003" - "17003:17003" volumes: - ./node3/redis.conf:/etc/redis/redis.conf - ./node3/data:/data command: redis-server /etc/redis/redis.conf networks: redis-cluster-net: ipv4_address: 172.20.0.4 redis-node4: image: redis:7 container_name: redis-node4 ports: - "7004:7004" - "17004:17004" volumes: - ./node4/redis.conf:/etc/redis/redis.conf - ./node4/data:/data command: redis-server /etc/redis/redis.conf networks: redis-cluster-net: ipv4_address: 172.20.0.5 redis-node5: image: redis:7 container_name: redis-node5 ports: - "7005:7005" - "17005:17005" volumes: - ./node5/redis.conf:/etc/redis/redis.conf - ./node5/data:/data command: redis-server /etc/redis/redis.conf networks: redis-cluster-net: ipv4_address: 172.20.0.6 redis-node6: image: redis:7 container_name: redis-node6 ports: - "7006:7006" - "17006:17006" volumes: - ./node6/redis.conf:/etc/redis/redis.conf - ./node6/data:/data command: redis-server /etc/redis/redis.conf networks: redis-cluster-net: ipv4_address: 172.20.0.7 networks: redis-cluster-net: driver: bridge ipam: config: - subnet: 172.20.0.0/16

4.启动所有容器（该过程会自动拉取镜像）

docker compose up -d

5.初始化 Redis 集群

输入以下命令进入任意一个容器

docker exec -it redis-node1 /bin/bash

执行集群创建命令

redis-cli --cluster create \ 172.20.0.2:7001 \ 172.20.0.3:7002 \ 172.20.0.4:7003 \ 172.20.0.5:7004 \ 172.20.0.6:7005 \ 172.20.0.7:7006 \ --cluster-replicas 1

当提示Can I set the above configuration? (type 'yes' to accept):时，输入yes确认。

如图即为成功
