1. 集群配置
3主 3从由于仅用于测试,故我这里只用1台服务器进行模拟
redis列表
2.编写redis.conf
在server上创建一个目录用于存放redis集群部署文件。这里我放的路径为/root/redis-cluster
在/opt/docker/redis-cluster目录下创建redis-1,redis-2,redis-3,redis-4,redis-5,redis-6文件夹
mkdir -p /opt/docker/redis-cluster/{redis-1,redis-2,redis-3,redis-4,redis-5,redis-6}
#创建持久化目录
mkdir -p /opt/docker/redis-cluster/redis-1/data
mkdir -p /opt/docker/redis-cluster/redis-2/data
mkdir -p /opt/docker/redis-cluster/redis-3/data
mkdir -p /opt/docker/redis-cluster/redis-4/data
mkdir -p /opt/docker/redis-cluster/redis-5/data
mkdir -p /opt/docker/redis-cluster/redis-6/data
3. 在每个redis-*文件夹下创建redis.conf文件,并写入如下内容:
cluster-enabled yes # 开启集群
cluster-config-file nodes.conf # 集群配置文件
cluster-node-timeout 5000 # 集群节点多少时间未响应视为该节点丢失
appendonly yes
port 6379 # redis监听端口
masterauth passwd123 #设置master节点密码
requirepass passwd123 #设置密码
注意:port值不能都为6379,根据上面redis列表设置的端口号,依次给redis-1 ~ redis-6设置6379~6384端口号
4.编写docker-compose.yml文件
这里直接使用daocloud提供的redis镜像地址daocloud.io/library/redis:6.0.4
在/root/redis-cluster文件夹下创建docker-compose.yml文件。
docker-compose.yml文件内容如下:
version: 3.1
services:
# redis1配置
redis1:
image: daocloud.io/library/redis:6.0.4
container_name: redis-1
restart: always
network_mode: “host”
volumes:
– /opt/docker/redis-cluster/redis-1/data:/data
– /opt/docker/redis-cluster/redis-1/redis.conf:/usr/local/etc/redis/redis.conf
command: [“redis-server”, “/usr/local/etc/redis/redis.conf”]
# redis2配置
redis2:
image: daocloud.io/library/redis:6.0.4
container_name: redis-2
restart: always
network_mode: “host”
volumes:
– /opt/docker/redis-cluster/redis-2/data:/data
– /opt/docker/redis-cluster/redis-2/redis.conf:/usr/local/etc/redis/redis.conf
command: [“redis-server”, “/usr/local/etc/redis/redis.conf”]
# redis3配置
redis3:
image: daocloud.io/library/redis:6.0.4
container_name: redis-3
restart: always
network_mode: “host”
volumes:
– /opt/docker/redis-cluster/redis-3/data:/data
– /opt/docker/redis-cluster/redis-3/redis.conf:/usr/local/etc/redis/redis.conf
command: [“redis-server”, “/usr/local/etc/redis/redis.conf”]
# redis4配置
redis4:
image: daocloud.io/library/redis:6.0.4
container_name: redis-4
restart: always
network_mode: “host”
volumes:
– /opt/docker/redis-cluster/redis-4/data:/data
– /opt/docker/redis-cluster/redis-4/redis.conf:/usr/local/etc/redis/redis.conf
command: [“redis-server”, “/usr/local/etc/redis/redis.conf”]
# redis5配置
redis5:
image: daocloud.io/library/redis:6.0.4
container_name: redis-5
restart: always
network_mode: “host”
volumes:
– /opt/docker/redis-cluster/redis-5/data:/data
– /opt/docker/redis-cluster/redis-5/redis.conf:/usr/local/etc/redis/redis.conf
command: [“redis-server”, “/usr/local/etc/redis/redis.conf”]
# redis6配置
redis6:
image: daocloud.io/library/redis:6.0.4
container_name: redis-6
restart: always
network_mode: “host”
volumes:
– /opt/docker/redis-cluster/redis-6/data:/data
– /opt/docker/redis-cluster/redis-6/redis.conf:/usr/local/etc/redis/redis.conf
command: [“redis-server”, “/usr/local/etc/redis/redis.conf”]
启动容器,执行命令:
#启动容器
docker-compose -f xxx.yaml up -d
5.开启集群
随便找一个容器进入,这里我选择redis-1进入。 在进入容器后,输入如下命令开启集群:
redis-cli –cluster create 192.168.66.180:6379
192.168.66.180:6380
192.168.66.180:6381
192.168.66.180:6382
192.168.66.180:6383
192.168.66.180:6384
–cluster-replicas 1
出现下图即为成功。
6.测试
使用redis-cli命令,连接集群中任意节点。(随便找一台能ping通集群所在IP的电脑,这里我用的本机进行测试)
6.1 查看节点属性
redis-cli -c -h 192.168.66.180 -p 6379
192.168.66.180:6379
