minio主从复制

minio主从复制、双击热备、两台节点

安装部署minio 主从都要装

1. 下载安装二进制的minio

cd /usr/local/bin
wget https://dl.min.io/server/minio/release/linux-amd64/minio
chmod +x minio
mkdir -p /usr/local/minio/data
mkdir -p /usr/local/minio/log

2. 创建启动脚本

#!/bin/bash
export MINIO_ROOT_USER=minioadmin
export MINIO_ROOT_PASSWORD=minioadmin
# nohup启动服务 指定文件存放路径 /root/data 还有设置日志文件路径 /root/minio/log
nohup /usr/local/bin/minio server --address :9002 --console-address :9001 /usr/local/minio/data > /usr/local/minio/log/minio.log 2>&1 &
给这个脚本加可执行的权限

3. 然后设置脚本开机自启动(从服务器和主服务器都这样设置minio)

​ 设置rc.local 开机启动

chmod u+x /etc/rc.d/rc.local
chmod u+x /etc/rc.local
给他权限让他能执行
vim /etc/rc.local
在exit 0 之前
添加 /usr/local/bin/minio.sh &
# &是在后台进行不妨碍终端
minio.sh是启动minio的脚本名字

如果是centos8以上需要把rc.local 加入到systemctl自启动里面

步骤如下：

1. vim /etc/systemd/system/rc.local.service

2. [Unit]
   Description=/etc/rc.local Compatibility
   ConditionPathExists=/etc/rc.local
   
   [Service]
   Type=forking
   ExecStart=/etc/rc.local start
   TimeoutSec=0
   StandardOutput=tty
   RemainAfterExit=yes
   SysVStartPriority=99
   
   [Install]
   WantedBy=multi-user.target
   

3. systemctl daemon - reload

4. systemctl enable rc.local.service

5. systemctl start rc.local.service

从服务器配置

1. 与主服务器配置过程一致(配置minio开机自启动和主服务器配置一样)
2. 从服务器下载mc

wget https://dl.min.io/client/mc/release/linux-amd64/mc -P /usr/local/bin/
chmod +x /usr/local/bin/mc

3. 配置同步

mc config host add minio_master http://192.168.200.28:9002 minioadmin minioadmin
mc config host add minio_slave http://192.168.200.90:9002 minioadmin minioadmin

4. 配置主从同步

mc mirror --remove --overwrite --watch minio_master minio_slave

5. 配置mc开机自启动

[root@localhost ~]# vim /usr/lib/systemd/system/mc.service 
[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

[root@localhost ~]# systemctl enable mc
[root@localhost ~]# systemctl start mc
