Minio 集群扩容存储空间，配合nginx 负载反向代理后端minio 集群服务器，提升高可用性

环境：Centos  7

软件：minio,Etcd

需求：通过联盟两个集群实例，实现水平扩容存储空间问题；

服务器使用阿里云，一共4台服务器(官方说明最好4台服务器做分布式，测试节省服务器所以我们使用两台服务器每台服务器两个目录，做一个假服务器代替，真实环境条件允许最好4台服务器操作)：

集群

Minio-1

Minio-2

IP 地址

172.31.78.244

172.31.78.243

172.31.78.241

172.31.78.242

计算名称地址

topsysfile.server.1.itusye.co

topsysfile.server.2.itusye.co

topsysfile.server.3.itusye.co

topsysfile.server.4.itusye.co

目录地址

/Data/minio/{data1,data2}

/Data/minio/{data1,data2}

官方说明：
可扩容：不同MinIO集群可以组成联邦，并形成一个全局的命名空间，并跨越多个数据中心，但不支持动态扩容；

https://docs.min.io/docs/minio-federation-quickstart-guide.html  官方参考 文档

1. 由于多个集群使用Etcd 联邦，所以我们先需要安装配置ETCD 服务，etcd 与zookeeper 服务器都是奇数性3，5，7 模式增加，etcd 安装配置我就简单跳过了，列出安装与配置；

[root@Minio-Storage-Services ~]# yum -y install etcd

[root@Minio-Storage-Services ~]# cat /etc/etcd/etcd.conf | grep -v '#'

ETCD_DATA_DIR="/var/lib/etcd/default.etcd"

ETCD_LISTEN_PEER_URLS="http://172.31.78.244:2380"  #内网通迅

ETCD_LISTEN_CLIENT_URLS="http://0.0.0.0:2379"     #外网通迅

ETCD_NAME="top-etcd-01"    #这里是集群连接地址，请注意与cluster 对应，与zookeeper myid  是一样的原理

ETCD_INITIAL_ADVERTISE_PEER_URLS="http://172.31.78.244:2380"

ETCD_ADVERTISE_CLIENT_URLS="http://0.0.0.0:2379"

ETCD_INITIAL_CLUSTER="top-etcd-01=http://172.31.78.244:2380,top-etcd-02=http://172.31.78.243:2380,top-etcd-03=http://172.31.78.241:2380"     #etcd 集群连接分配地址，注意三台服务器一样

ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster"

ETCD_INITIAL_CLUSTER_STATE="new"

ETCD_STRICT_RECONFIG_CHECK="true"

以上服务器配置是172.31.78.244 这台

    link/ether ::3e::: brd ff:ff:ff:ff:ff:ff

ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster"

ETCD_INITIAL_CLUSTER_STATE="new"

ETCD_STRICT_RECONFIG_CHECK="true"

[root@Minio-Storage-Services ~]#

etcd 已安装完成；

2.  下载minio , 4台配置服务器同样的配置如下；

[root@Minio-Storage-Services ~]#  wget https://dl.min.io/server/minio/release/linux-amd64/minio

[root@Minio-Storage-Services ~]# chmod +x minio

[root@Minio-Storage-Services ~]# mv minio /usr/local/bin/

[root@Minio-Storage-Services ~]# mkdir /usr/local/minio{bin,config} -p

[root@Minio-Storage-Services ~]# mkdir /Data/minio/{data1,data2} -p

[root@Minio-Storage-Services ~]# firewall-cmd --zone=public --add-port=/tcp --add-port=/tcp --permanent && firewall-cmd --reload

[root@Minio-Storage-Services ~]# firewall-cmd --zone=public --add-port=/tcp --permanent

[root@Minio-Storage-Services ~]# systemctl restart firewalld

3. 编辑启动脚本，两个集群，两份配置不一样，由于我配置了hosts，所以etcd 连接使用了域名

[root@Minio-Storage-Services ~]# more /etc/hosts

::     localhost       localhost.localdomain   localhost6      localhost6.localdomain6

127.0.0.1       localhost       localhost.localdomain   localhost4      localhost4.localdomain4

172.31.78.243   topsysfile.server..itusye.co

172.31.78.241   topsysfile.server..itusye.co

172.31.78.242   topsysfile.server..itusye.co

[root@Minio-Storage-Services ~]#

Minio-1集群配置，两台服务器同样的配置；

    link/ether ::3e:::6b brd ff:ff:ff:ff:ff:ff

minio server --config-dir /usr/local/minio/config/ \   # 官方提示：--config-dir 选项要停止使用了，此选择主要创建一个certs目录存放ca 信息

[root@Minio-Storage-Services ~]#

4 配置启动脚本，所有服务器同样的配置；

[root@Minio-Storage-Services ~]# more /usr/lib/systemd/system/minio.service

[Unit]

Description=Minio service

Documentation=https://docs.minio.io/

[Service]

WorkingDirectory=/usr/local/minio/

ExecStart=/usr/local/minio/bin/run.sh

Restart=on-failure

RestartSec=

[Install]

WantedBy=multi-user.target

[root@Minio-Storage-Services ~]#

5.配置nginx , https://docs.min.io/docs/setup-nginx-proxy-with-minio.html   官方参考文档

主要需要注意：客户端上传限制的问题

client_max_body_size 2048M;
client_body_buffer_size 500M;

以下为nginx Server 模块配置

upstream topfilestorage-minio{

                ip_hash;

                server topsysfile.server..toptech.ph: weight= max_fails= fail_timeout=10s;

                server topsysfile.server..toptech.ph: weight= max_fails= fail_timeout=10s;

                server topsysfile.server..toptech.ph: weight= max_fails= fail_timeout=10s;

                #       check interval= rise= fall= timeout= default_down=true type=http;

}

server {

        listen ;

        server_name localhost;

        if ($scheme = http ) {

                return  https://$host$request_uri;

                }

        }

server {

         server_name localhost;

                listen ;

                ssl on;

                }

                ignore_invalid_headers off;

                proxy_buffering off;

                location / {

                        proxy_pass http://topfilestorage-minio;

                        include conf.d/proxy.conf;

                }

}

以下proxy.conf 文档

[root@Minio-Storage-Services ~]# more /usr/local/nginx/config/conf.d/proxy.conf | grep -v '#'

proxy_http_version 1.1;

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_set_header Host $http_host;

proxy_set_header Connection "";

chunked_transfer_encoding off;

[root@Minio-Storage-Services ~]#

以上集群已配置完成，测试新建文件夹会自动选择集群存储，并且测试如果固定用一个集群创建一个根目录文件夹，再用另外一个集群或者反向代理去上传都是可以把数据上传存储到文件夹所在的集群空间里，两个集群内的数据并不会同步，但是在存储时minio 会自动计算选择集群存储；

MinIO是一个开源的对象存储解决方案，优点如下：

  1. 高性能：作为高性能对象存储，在标准硬件条件下它能达到55GB/s的读、35GG/s的写速率
  2. 可扩容：不同MinIO集群可以组成联邦，并形成一个全局的命名空间，并跨越多个数据中心
  3. 云原生：容器化、基于K8S的编排、多租户支持
  4. 兼容性：兼容S3 API这一事实上的对象存储标准，最先支持S3 Select
  5. 简单：这一设计原则让MinIO不容易出错、更快启动
  6. 支持纠删码：MinIO使用纠删码、Checksum来防止硬件错误和静默数据污染。在最高冗余度配置下，即使丢失1/2的磁盘也能恢复数据
