這篇文章介紹了如何在Docker環(huán)境下創(chuàng)建Redis集群的步驟,包括解決Redis鏡像問題、配置國(guó)內(nèi)加速、準(zhǔn)備部署、創(chuàng)建配置文件、編寫docker-compose.yml、執(zhí)行部署命令、創(chuàng)建集群、驗(yàn)證集群和查看集群信息等,感興趣的朋友跟隨小編一起看看吧

首先要解決的問題是redis鏡像的問題，如果因網(wǎng)絡(luò)問題無法docker pull，就配置國(guó)內(nèi)加速
創(chuàng)建文件

touch /etc/docker/daemon.json

寫入內(nèi)容

{
    "registry-mirrors": [
        "https://docker.1panel.live",
        "https://docker-0.unsee.tech",
        "https://docker.1panel.live",
        "https://registry.dockermirror.com",
        "https://docker.imgdb.de",
        "https://docker.m.daocloud.io",
        "https://hub.firefly.store",
        "https://hub.littlediary.cn",
        "https://hub.rat.dev",
        "https://dhub.kubesre.xyz",
        "https://cjie.eu.org",
        "https://docker.kejilion.pro",
        "https://docker.1panelproxy.com",
        "https://docker.hlmirror.com",
        "https://hub.fast360.xyz",
        "https://ghcr.io"
    ]
}

其次就開始準(zhǔn)備著手部署redis集群
1、創(chuàng)建redis.conf,每個(gè)節(jié)點(diǎn)一個(gè)文件【redis1.conf，redis2.conf，redis3.conf，redis4.conf，redis5.conf，】，端口不能相同，conf文件內(nèi)容如下，下方的注釋要移除，不要在文件中體現(xiàn)，會(huì)報(bào)錯(cuò)

port 6379 
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes
appendfsync everysec
requirepass 123456 #redis密碼
masterauth 123456 #redis集群節(jié)點(diǎn)認(rèn)證密碼
maxmemory 1gb
maxmemory-policy allkeys-lru

2、創(chuàng)建好配置文件后，創(chuàng)建docker-compose.yml，內(nèi)容如下，有需要調(diào)整的自行調(diào)整即可

version: "3.8"
services:
  redis-master1:
    image: redis:6-alpine
    container_name: redis-master1
    environment:
      - "TZ=Asia/Shanghai"
    ports:
      - "6379:6379"
      - "16379:16379"
    volumes:
      - ./redis.conf:/usr/local/etc/redis/redis.conf
      - ./redis-master1/data:/data
    command:
      - "redis-server"
      - "/usr/local/etc/redis/redis.conf"
  redis-master2:
    image: redis:6-alpine
    container_name: redis-master2
    environment:
      - "TZ=Asia/Shanghai"
    ports:
      - "6380:6380"
      - "16380:16380"
    volumes:
      - ./redis1.conf:/usr/local/etc/redis/redis.conf
      - ./redis-master2/data:/data
    command:
      - "redis-server"
      - "/usr/local/etc/redis/redis.conf"
  redis-master3:
    image: redis:6-alpine
    container_name: redis-master3
    environment:
      - "TZ=Asia/Shanghai"
    ports:
      - "6381:6381"
      - "16381:16381"
    volumes:
      - ./redis2.conf:/usr/local/etc/redis/redis.conf
      - ./redis-master3/data:/data
    command:
      - "redis-server"
      - "/usr/local/etc/redis/redis.conf"
  redis-slave1:
    image: redis:6-alpine
    container_name: redis-slave1
    environment:
      - "TZ=Asia/Shanghai"
    ports:
      - "6382:6382"
      - "16382:16382"
    volumes:
      - ./redis3.conf:/usr/local/etc/redis/redis.conf
      - ./redis-slave1/data:/data
    command:
      - "redis-server"
      - "/usr/local/etc/redis/redis.conf"
  redis-slave2:
    image: redis:6-alpine
    container_name: redis-slave2
    environment:
      - "TZ=Asia/Shanghai"
    ports:
      - "6383:6383"
      - "16383:16383"
    volumes:
      - ./redis4.conf:/usr/local/etc/redis/redis.conf
      - ./redis-slave2/data:/data
    command:
      - "redis-server"
      - "/usr/local/etc/redis/redis.conf"
  redis-slave3:
    image: redis:6-alpine
    container_name: redis-slave3
    environment:
      - "TZ=Asia/Shanghai"
    ports:
      - "6384:6384"
      - "16384:16384"
    volumes:
      - ./redis5.conf:/usr/local/etc/redis/redis.conf
      - ./redis-slave3/data:/data
    command:
      - "redis-server"
      - "/usr/local/etc/redis/redis.conf"

3、在docker-compose.yml文件所在文件夾下，同時(shí)redis.conf也要在該文件夾下，執(zhí)行命令

docker-compose up -d

4、執(zhí)行成功后，進(jìn)入任意一個(gè)容器

docker exec -it redis-master1 sh

5、執(zhí)行如下命令，創(chuàng)建集群。此處注意，各個(gè)節(jié)點(diǎn)的ip一定要保證能夠在容器內(nèi)與之通信，否則無法建立集群，如果有需要對(duì)網(wǎng)絡(luò)調(diào)整的，在docker-compose.yml進(jìn)行配置

redis-cli --cluster create 192.168.1.202:6379 192.168.1.202:6380 192.168.1.202:6381 192.168.1.202:6382 192.1681.202:6383 192.168.1.202:6384 --cluster-replicas 1 -a '123456'

6、集群創(chuàng)建成功，開始驗(yàn)證，在集群中的節(jié)點(diǎn)中輸入命令
