Docker-Compose搭建MinIO集群 - 《Java？Java！》

一、安装Docker
二、安装Docker-Compose
三、用Docker-Compose搭建MinIO集群

一、安装Docker

环境：CentOS7

安装官方给的方法进行安装，首先先卸载旧版本的环境：

$ sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

没找到，没找到正常，因为服务器从来没安装过docker，哈哈哈哈

然后第二步，安装需要的依赖：

$ sudo yum install -y yum-utils
$ sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

然后安装最新的Docker：

$ sudo yum install docker-ce docker-ce-cli containerd.io

安装完成后，我们启动docker：

systemctl start docker

查看docker是否安装成功：

docker -v

docker下载源默认是国外的，我们需要切换到国内源：

我这里选用的是网易的源，首先修改或新增 /etc/docker/daemon.json，修改内容为：

vi /etc/docker/daemon.json
{
"registry-mirrors": ["http://hub-mirror.c.163.com"]
}
systemctl restart docker

二、安装Docker-Compose

sudo curl -L "https://github.com/docker/compose/releases/download/1.27.4/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

下载慢可以用这个：

curl -L https://get.daocloud.io/docker/compose/releases/download/1.27.4/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

赋予可执行权限：

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

然后查看版本：

docker-compose --version

说明docker-compose已经安装成功

三、用Docker-Compose搭建MinIO集群

查看官方文档，下载docker-compose.yaml与nginx.conf

docker-compose.yaml

version: '3.7'
# starts 4 docker containers running minio server instances.
# using nginx reverse proxy, load balancing, you can access
# it through port 9000.
services:

    expose:
      - "9000"
    environment:

      MINIO_SECRET_KEY: minio123
    command: server http://minio{1...4}/data{1...2}
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:9000/minio/health/live"]
      interval: 30s
      timeout: 20s
      retries: 3
  nginx:
    image: nginx:1.19.2-alpine
    volumes:
      - ./nginx.conf:/etc/nginx/nginx.conf:ro
    ports:

    depends_on:
      - minio1
      - minio2
      - minio3
      - minio4
## By default this config uses default local driver,
## For custom volumes replace with volume driver configuration.
volumes:

nginx.conf

user  nginx;
worker_processes  auto;
error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;
events {
    worker_connections  1024;
}
http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '

    access_log  /var/log/nginx/access.log  main;
    sendfile        on;
    #tcp_nopush     on;
    keepalive_timeout  65;
    #gzip  on;
    # include /etc/nginx/conf.d/*.conf;
    upstream minio {
        server minio1:9000;
        server minio2:9000;
        server minio3:9000;
        server minio4:9000;
    }
    server {
        listen       9000;
        listen  [::]:9000;
        server_name  localhost;
         # To allow special characters in headers
         ignore_invalid_headers off;
         # Allow any size file to be uploaded.
         # Set to a value such as 1000m; to restrict file size to a specific value
         client_max_body_size 0;
         # To disable buffering
         proxy_buffering off;
        location / {
            proxy_set_header Host $http_host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto $scheme;
            proxy_connect_timeout 300;
            # Default is HTTP/1, keepalive is only enabled in HTTP/1.1
            proxy_http_version 1.1;
            proxy_set_header Connection "";
            chunked_transfer_encoding off;
            proxy_pass http://minio;
        }
    }
}

然后执行命令

docker-compose pull
docker-compose up -d /*-d代表后台运行*/

然后查看docker状态

docker ps

这样，用docker-compose搭建minio集群就完成了
