一、基础概览
1、redis集群最少需要6个节点,且redis集群下只有db0,不支持多db。
2、开放端口
节点访问:6391-6393
集群连接:16391-16393
二、准备容器挂载的目录
1.创建根目录
mkdir /server
cd /server
2.创建容器目录。然后给每个节点创建对应的目录和配置文件
服务器1 192.168.79.131
init.sh
for port in $(seq 6391 6393); \
do \
mkdir -p /server/redis-cluster/redis-node-${port}/{conf,data}
touch /server/redis-cluster/redis-node-${port}/conf/redis.conf
cat << EOF >/server/redis-cluster/redis-node-${port}/conf/redis.conf
#端口
port ${port}
bind 0.0.0.0
#启用集群模式
cluster-enabled yes
cluster-config-file nodes.conf
#超时时间
cluster-node-timeout 5000
# 集群连接地址及端口
cluster-announce-ip 192.168.79.131
cluster-announce-port ${port}
cluster-announce-bus-port 1${port}
appendonly yes
#集群加密
masterauth 123456
requirepass 123456
EOF
done
服务器2 192.168.79.132
init.sh
for port in $(seq 6391 6393); \
do \
mkdir -p /server/redis-cluster/redis-node-${port}/{conf,data}
touch /server/redis-cluster/redis-node-${port}/conf/redis.conf
cat << EOF >/server/redis-cluster/redis-node-${port}/conf/redis.conf
#端口
port ${port}
bind 0.0.0.0
#启用集群模式
cluster-enabled yes
cluster-config-file nodes.conf
#超时时间
cluster-node-timeout 5000
# 集群连接地址及端口
cluster-announce-ip 192.168.79.132
cluster-announce-port ${port}
cluster-announce-bus-port 1${port}
protected-mode no
appendonly yes
#集群加密
masterauth 123456
requirepass 123456
EOF
done
三、使用docker-compose.yml
运行redis
容器
version: '3'
services:
redis1:
container_name: redis1
image: redis:7.0.5
network_mode: host
restart: always
volumes:
- /server/redis-cluster/redis-node-6391/conf/redis.conf:/etc/redis/redis.conf
- /server/redis-cluster/redis-node-6391/data:/data
environment:
- TZ=Asia/Shanghai
- LANG=en_US.UTF-8
ports:
- '6391:6379' #服务端口
- '16391:16379' #集群端口
command: ["redis-server", "/etc/redis/redis.conf"]
privileged: true #环境变量
redis2:
container_name: redis2
image: redis:7.0.5
network_mode: host
restart: always
volumes:
- /server/redis-cluster/redis-node-6392/conf/redis.conf:/etc/redis/redis.conf
- /server/redis-cluster/redis-node-6392/data:/data
environment:
- TZ=Asia/Shanghai
- LANG=en_US.UTF-8
ports:
- '6392:6379' #服务端口
- '16392:16379' #集群端口
command: ["redis-server", "/etc/redis/redis.conf"]
privileged: true #环境变量
redis3:
container_name: redis3
image: redis:7.0.5
network_mode: host
restart: always
volumes:
- /server/redis-cluster/redis-node-6393/conf/redis.conf:/etc/redis/redis.conf
- /server/redis-cluster/redis-node-6393/data:/data
environment:
- TZ=Asia/Shanghai
- LANG=en_US.UTF-8
ports:
- '6393:6379' #服务端口
- '16393:16379' #集群端口
command: ["redis-server", "/etc/redis/redis.conf"]
privileged: true #环境变量
分别在两台服务器上执行
docker-compose up -d
四、组建redis
集群
随便进一台服务器进行配置
进入某一个容器
docker exec -it redis1 /bin/bash
组建集群
redis-cli -p 6391 -a 123456 --cluster create 192.168.79.131:6391 192.168.79.131:6392 192.168.79.131:6393 192.168.79.132:6391 192.168.79.132:6392 192.168.79.132:6393 --cluster-replicas 1
输入yes即可
五、查看集群信息
主从关系
redis-cli -p 6391 -a 123456
#查看节点
cluster nodes
