minio主从同步和双机热备

环境说明

1. 安装

• 下载地址：
  http://dl.minio.org.cn/client/mc/release/linux-amd64/mc

• 安装

  • 只有一个二进制文件，放到目标服务器的/usr/local/bin/下即可
  • 我是放在minio-backup上

• 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.
Added `minio_master` successfully.

• 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]
Description=startup minioc mirror master to slave
After=network.target

[Service]
Type=simple
ExecStart=/usr/local/bin/mc mirror --remove --overwrite --watch  minio_master  minio_slave

Restart=on-failure

[Install]
WantedBy=multi-user.target

• 启动服务

systemctl start minioc.service

• 设置开机自启

systemctl enable minioc.service

• 查看服务状态

● minioc.service - startup minioc mirror master to slave
   Loaded: loaded (/usr/lib/systemd/system/minioc.service; enabled; vendor preset: disabled)

2. 测试

• 登录salver，可以看到master上的文件已经同步进来了。

• 登录master，创建bucket或上传图片，可以看到，slave都能同步

3. 双机热备

• 用同样方法，在master上也安装一个mc，配置方法也相同。
