一键安装配置脚本

# 一键安装配置
# 支持的发行版

        echo "centos"

    fi
}

            ;;
        ubuntu|debian)

        ubuntu|debian)
            add-apt-repository -y ppa:gluster/glusterfs-9
            apt-get update
            apt-get install -y glusterfs-server
            ;;
    esac
    systemctl start glusterd
    systemctl enable glusterd
}
# 主流程
OS=$(detect_os)
install_dependencies "$OS"
install_gluster "$OS"
echo "GlusterFS安装完成"

使用说明

1. 保存脚本: 将脚本保存为 .sh 文件
2. 设置权限: chmod +x script.sh
3. 运行: ./script.sh

注意事项

• 确保所有节点间网络互通
• 配置好主机名解析（/etc/hosts）
• 关闭防火墙或配置相应规则
• 每个brick使用独立磁盘分区
• 生产环境建议使用RAID或分布式复制卷

这些脚本涵盖了GlusterFS的自动部署、配置和监控，可以根据实际环境调整参数。
