1、安装docker
1、安装依赖包

yum install -y yum-utils device-mapper-persistent-data lvm2

2、配置docker yum源

yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

3、安装docker

yum install -y docker-ce

4、修改docker配置文件


mkdir /etc/docker -p

sudo tee /etc/docker/daemon.json <<-'EOF'

{

    "registry-mirrors": [

      "https://docker.credclouds.com",

      "https://k8s.credclouds.com",

      "https://quay.credclouds.com",

      "https://gcr.credclouds.com",

      "https://k8s-gcr.credclouds.com",

      "https://ghcr.credclouds.com",

      "https://do.nark.eu.org",

      "https://docker.m.daocloud.io",

      "https://docker.nju.edu.cn",

      "https://docker.mirrors.sjtug.sjtu.edu.cn",

      "https://docker.1panel.live",

      "https://docker.rainbond.cc"

    ],

   "data-root": "/etc/docker"

}

EOF

5、启动docker

systemctl daemon-reload

systemctl enable docker --now

systemctl restart docker

6、安装docker-compose

#下载docker-compose文件

curl -L "https://github.com/docker/compose/releases/download/v2.29.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

#给他一个执行权限

chmod +x /usr/local/bin/docker-compose

ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

#查看是否安装成功

docker-compose --version

2、拉取镜像

docker pull redis:latest

services:
  redis:
    image: redis:latest
    container_name: redis7001
    command: redis-server /usr/local/etc/redis/redis.conf
    #command: redis-server --requirepass redis5012##00 
#    sysctls:
#      - net.core.somaxconn=1024
    volumes:
      - /data/redis7001/data:/data
      - /data/redis7001/conf/redis.conf:/usr/local/etc/redis/redis.conf
      - /data/redis7001/logs:/logs
      - /etc/localtime:/etc/localtime
    ports:
      - "7001:7001"
#      - "17001:16379"
    restart: always
    network_mode: host
#    networks:
#      - mynet
#networks:
#  mynet:
#    driver: bridge
EOF
sudo tee /data/redis7002/docker-compose.yml <<-'EOF'
version: '3.8'

services:
  redis:
    image: redis:latest
    container_name: redis7002
    command: redis-server /usr/local/etc/redis/redis.conf
    #command: redis-server --requirepass redis5012##00

    restart: always
    network_mode: host
#    networks:
#      - mynet
#networks:
#  mynet:
#    driver: bridge
EOF

6、启动redis服务

cd /data/redis7001

docker-compose up -d

docker-compose ps



cd /data/redis7002

docker-compose up -d

docker-compose ps

7、redis集群初始化
进入任意 Redis 容器

docker exec -it redis7001 /bin/sh

执行创建集群

redis-cli -a redis5012##00 --cluster create 192.168.52.15:7001 192.168.52.15:7002 192.168.52.16:7001 192.168.52.16:7002 192.168.52.17:7001 192.168.52.17:7002 --cluster-replicas 1

创建成功后连接任意一个redis节点

redis-cli -a redis5012##00 -c -h 192.168.52.15 -p 7001

查看集群信息
