在三台服务器上使用docker搭建集群

集群环境搭建

Minio集群

参考-->minio
所有节点配置主机名解析：

cat >> /etc/hosts << EOF
192.168.86.58 minio-1
192.168.86.19 minio-2
192.168.86.43 minio-3
EOF

使用docker run运行minio

部署minio集群，3个节点每个节点挂载2个目录
minio-1节点执行

docker run -d --name minio \
  --restart=always --net=host \
  -e MINIO_ACCESS_KEY=minio \
  -e MINIO_SECRET_KEY=minio123 \
  -v minio-data1:/data1 \
  -v minio-data2:/data2 \
  minio/minio server \
  --address 192.168.86.58:9000 \
  http://minio-{1...3}/data{1...2}

minio-2节点执行

docker run -d --name minio \
  --restart=always --net=host \
  -e MINIO_ACCESS_KEY=minio \
  -e MINIO_SECRET_KEY=minio123 \
  -v minio-data1:/data1 \
  -v minio-data2:/data2 \
  minio/minio server \
  --address 192.168.86.19:9000 \
  http://minio-{1...3}/data{1...2}

minio-3节点执行

docker run -d --name minio \
  --restart=always --net=host \
  -e MINIO_ACCESS_KEY=minio \
  -e MINIO_SECRET_KEY=minio123 \
  -v minio-data1:/data1 \
  -v minio-data2:/data2 \
  minio/minio server \
  --address 192.168.92.12:9000 \
  http://minio-{1...3}/data{1...2}

说明：docker部署集群模式时必须指定–net=host参数，使用主机网络，使用端口映射无法创建集群。

使用docker-compose部署minio

都要先更改/etc/hosts中的域名解析
*在192.168.86.58上的docker-compose

version: "3.2"
services:
  minio3:
    container_name: minio
    image: minio/minio:RELEASE.2020-08-08T04-50-06Z
    restart: always
    volumes:
      - ./minio-data1:/data1
      - ./minio-data2:/data2
    ports:
      - "9000:9000"
    environment:
      MINIO_ACCESS_KEY: minio
      MINIO_SECRET_KEY: minio123
    command: server http://minio-{1...3}/data{1...2}
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:9000/minio/health/live"]
      interval: 30s
      timeout: 20s
      retries: 3
    network_mode: host

其他两台的配置同上

Nacos集群

参考-->nacos

主机	服务
192.168.86.58	nacos01
192.168.86.19	nacos02
192.168.86.43	nacos03

在主机为192.168.86.58上安装mysql(我安装的是mysql5.7.38)
创建nacos数据库
运行以下脚本:
也可以在官方文档去找：

Redis集群

参考-->redis

分别在三台主机上创建如下文件和文件夹

mkdir -p /usr/local/docker/redis
cd /usr/local/docker/redis
touch docker-compose.yaml
vim docker-compose.yaml
192.168.86.58的docker-compose.yaml

version: '3'
services:
  master:
    image: redis
    container_name: redis-master
    restart: always
    command: redis-server --port 6379 --requirepass test1234 --masterauth test1234 --appendonly yes
    ports:
      - 6379:6379
    privileged: true
    volumes:
      - /usr/local/docker/redis/data:/data
      - /usr/local/docker/redis/conf/:/usr/local/etc/redis/

192.168.86.19的docker-compose.yaml

version: '3'
services:
  redis-slave1:
    image: redis
    container_name: redis-slave1
    restart: always
    command: redis-server --slaveof 192.168.86.58 6379 --port 6379 --requirepass test1234 --masterauth test1234 --appendonly yes
    ports:
      - 6379:6379
    privileged: true
    volumes:
      - /usr/local/docker/redis/data:/data
      - /usr/local/docker/redis/conf/:/usr/local/etc/redis/

192.168.86.43的docker-compose.yaml

version: '3'
services:
  redis-slave2:
    image: redis
    container_name: redis-slave2
    restart: always
    command: redis-server --slaveof 192.168.86.58 6379 --port 6379 --requirepass test1234 --masterauth test1234 --appendonly yes
    ports:
      - 6379:6379
    privileged: true
    volumes:
      - /usr/local/docker/redis/data:/data
      - /usr/local/docker/redis/conf/:/usr/local/etc/redis/

参数解释：
privileged: true 权限
requirepass test1234 访问本机需要的密码
masterauth test1234 作为从机访问主机的密码
appendonly yes 是否持久化

docker-compose up -d 后台启动
后面可以用docker ps查看容器是否正常启动
docker-compose down 关闭

进入docker exec -it redis-master bash
输入redis-cli

如果你更改了端口号,在进入集群的时候,要使用redis-cli -p 端口号(如果是6379就不用加-p)

在输入info

哨兵模式

在/usr/local/docker/redis这个目录下创建新的文件夹sentinel
mkdir sentinel
cd sentinel
touch sentinel.conf
touch docker-compose.yml

192.168.86.63的sentinel.conf编写：（其他两台服务器也可以使用26379，因为从属不同的服务器）

# bind 127.0.0.1 192.168.1.1
# protected-mode no
port 26379
#daemonize yes
#pidfile /var/run/redis-sentinel.pid
logfile "sentinel.log"
sentinel monitor redis-master 192.168.86.58 6379 2
sentinel auth-pass redis-master test1234
sentinel down-after-milliseconds redis-master 10000

sentinel announce-ip "192.168.86.58"
sentinel announce-port 26379

sentinel deny-scripts-reconfig yes

其他两台的配置文件和上面的一样

docker-compose.yaml文件
192.168.86.58

version: '3'
services:
  redis-sentinel-1:
    image: redis
    container_name: redis-sentinel-1
    command: redis-sentinel /usr/local/etc/redis/sentinel.conf
    ports:
      - 26379:26379
	privileged: true
    volumes:
      - /usr/local/docker/redis/sentinel:/usr/local/etc/redis/

192.168.86.19

version: '3'
services:
  redis-sentinel-2:
    image: redis
    container_name: redis-sentinel-2
    command: redis-sentinel /usr/local/etc/redis/sentinel.conf
    ports:
      - 26379:26379
	privileged: true
    volumes:
      - /usr/local/docker/redis/sentinel:/usr/local/etc/redis/

192.168.86.43

version: '3'
services:
  redis-sentinel-3:
    image: redis
    container_name: redis-sentinel-3
    command: redis-sentinel /usr/local/etc/redis/sentinel.conf
    ports:
      - 26379:26379
	privileged: true
    volumes:
      - /usr/local/docker/redis/sentinel:/usr/local/etc/redis/

启动哨兵：docker-compose up -d

进入哨兵的容器中:
docker exec -it 容器名称 bash
进去集群: redis-cli -p 26379(你设置的端口,我设置的是26379)
输入:info查看当前的配置信息
