minio集群部署
1.说明：
安装前需要再添加一个磁盘后将磁盘挂载到/opt/minio目录,minio集群部署需要独占磁盘分区，不能使用文件夹代替。
运行分布式 MinIO 实例的服务器时间差不应超过15分钟
所有运行分布式 MinIO 设置的节点都是同构的，即相同的操作系统、相同数量的磁盘和相同的网络互连 。
MinIO 的节点需要具有相同的访问密钥和秘密密钥才能连接，即access key 和 MINIO secret key 都要一样。
2.创建目录
mkdir -p /opt/minio/{run,data} && mkdir -p /etc/minio
3.挂载新的硬盘
挂载/opt/minio目录，忘记的话，搜linux挂载新硬盘
挂载完后，记得配置文件 /etc/fstab 也需要增加，不然服务器重启之后，就掉盘了
/dev/sdb1 /opt/minio ext4 defaults 0 0
4.下载Minio到/opt/minio/run
cd /opt/minio/run
wget https://dl.min.io/server/minio/release/linux-amd64/minio
5.创建启动脚本文件
vim /opt/minio/run/run.sh
#Minio默认9000端口，在配置文件中加入–address “127.0.0.1:9029” 可更改端口
#注意 ：
#MINIO_ROOT_USER：用户名，长度最小是5个字符
#MINIO_ROOT_PASSWORD：密码，密码不能设置过于简单，不然minio会启动失败，长度最小是8个字符
#–config-dir：指定集群配置文件目录
#!/bin/bash
export MINIO_ROOT_USER=admin
export MINIO_ROOT_PASSWORD=adminbfd123
/opt/minio/run/minio server --config-dir /etc/minio
--address "0.0.0.0:9029" --console-address ":9000"
http://172.16.11.1:9029/opt/minio/data
http://172.16.11.2:9029/opt/minio/data > minio_server.log
6.创建停止脚本文件
cat <<EOF > /opt/minio/run/stop.sh
!/bin/bash
MinIO停止脚本
ps -ef | grep minio | grep -v 'grep' | awk '{print $2}'| xargs kill -9
if $? != 0;then
echo "minio service stop failed."
exit 1
fi
EOF
7.创建Minio.server
cat <<EOF > /etc/systemd/system/minio.service
[Unit]
Description=Minio service
Documentation=https://docs.minio.io/
[Service]
WorkingDirectory=/opt/minio/run/
ExecStart=/opt/minio/run/run.sh
ExecStop=/opt/minio/run/stop.sh
Restart=on-failure
RestartSec=5
[Install]
WantedBy=multi-user.target
EOF
8、权限修改
chmod +x /etc/systemd/system/minio.service && chmod +x /opt/minio/run/minio && chmod +x /opt/minio/run/run.sh && chmod +x /opt/minio/run/stop.sh
9.启动集群（依次执行命令）
systemctl daemon-reload
systemctl start minio
systemctl enable minio
systemctl status minio.service
10.配置nginx代理
vim minio-cluster.conf
配置文件内容：
# websocket
map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}
upstream minio_console {
server 172.16.11.1:9000 max_fails=3 fail_timeout=5s;
server 172.16.11.2:9000 max_fails=3 fail_timeout=5s;
}
upstream minio_api {
server 172.16.11.1:9029 max_fails=3 fail_timeout=5s;
server 172.16.11.2:9029 max_fails=3 fail_timeout=5s;
}
server {
listen 80;
listen 443 ssl;
server_name cons.minio.com;
ssl_certificate keys/abcty6/server.crt;
ssl_certificate_key keys/abcty6/server.key;
ssl_session_cache shared:SSL:1m;
ssl_session_timeout 10m;
ssl_ciphers HIGH:!aNULL:!MD5;
ssl_prefer_server_ciphers on;
client_max_body_size 1G; #如果上传文件大于1G，就需要更改这个参数
client_header_timeout 1m;
client_body_timeout 1m;
proxy_connect_timeout 60s;
proxy_read_timeout 1m;
proxy_send_timeout 1m;
location / {
proxy_next_upstream http_500 http_502 http_503 http_504 error timeout invalid_header;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;
proxy_http_version 1.1;
proxy_pass http://minio_console;
expires 0;
}
}
server {
listen 80;
listen 443 ssl;
server_name apapi.minio.com;
ssl_certificate keys/abcty6/server.crt;
ssl_certificate_key keys/abcty6/server.key;
ssl_session_cache shared:SSL:1m;
ssl_session_timeout 10m;
ssl_ciphers HIGH:!aNULL:!MD5;
ssl_prefer_server_ciphers on;
client_max_body_size 1G;
client_header_timeout 1m;
client_body_timeout 1m;
proxy_connect_timeout 60s;
proxy_read_timeout 1m;
proxy_send_timeout 1m;
location / {
proxy_next_upstream http_500 http_502 http_503 http_504 error timeout invalid_header;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://minio_api;
expires 0;
}
}
重载配置
./nginx -s reload
至此，集群成功！
11.数据迁移
### 11.1下载mc
wget https://dl.min.io/client/mc/release/linux-amd64/mc
chmod +x mc
./mc --help
./mc config host add hk http://172.16.11.1:9029
11.2给远程主机批量创建桶名
11.3拷贝文件和对象到新的服务器
