主节点配置

[root@liubei minio]# mc config host add minio_master http://10.10.xxx.251:9000 minio liubei@161
mc: Configuration written to `/root/.mc/config.json`. Please update your access credentials.
mc: Successfully created `/root/.mc/share`.
mc: Initialized share uploads `/root/.mc/share/uploads.json` file.
mc: Initialized share downloads `/root/.mc/share/downloads.json` file.

输出可知，主配置文件在 /root/.mc/config.json

从节点配置

[root@luibei minio]# mc config host add minio_slave http://10.10.xxx.204:9000 minio liubei@161
Added `minio_slave` successfully.

创建启动文件/usr/lib/systemd/system/minioc.service，内容如下：

[Unit]
