存储服务器架设要求，bin/bash

存储服务器架设要求及bash自动化部署方案如下：硬件需配备多路冗余电源、至少16GB内存及500GB以上RAID10阵列，操作系统基于Ubuntu 20.04 LTS精简版，网络配置要求启用SSH密钥认证（通过bash脚本自动生成并部署），防火墙需保留22/80端口，存储方案采用LVM+RAID6架构，通过bash脚本实现自动卷组创建、磁盘扩展及快照备份，安全措施包括定期更新（cron任务）、日志审计（logrotate配置）及自动漏洞扫描（unattended-upgrades），监控集成ZabbixAgent，通过bash脚本批量安装监控插件，部署流程使用bash函数实现：服务器初始化→网络配置→存储创建→服务安装→权限管控→测试验证，完整脚本支持参数化输入（如存储容量、网络地址），最终通过bash + Ansible混合模式实现跨节点集群部署，确保存储服务高可用与自动化运维。

项目背景与需求分析（421字） 1.1 存储服务架构演进趋势 在数字化转型加速的背景下，企业存储需求呈现指数级增长，IDC最新报告显示，全球数据总量将在2025年突破175ZB，其中企业级数据占比达68%,传统存储架构已难以满足：

• 多PB级数据存储需求
• 混合负载（OLTP/OLAP）处理能力
• 全球分布式存储需求
• 999%可用性要求

2 Ceph集群部署要点 （分步操作指南）

1. 集群初始化：

   ceph --new

   ceph auth add mon.1 10.10.10.1

   ceph auth add osd.1 10.10.10.2

2. 节点注册：

   ceph osd pool create data -p 128 -m 2

   ceph osd pool set data 128 2

3. 优先级配置： [osd] osd pool default size = 128 osd pool default min size = 64

4. 安全加固：

   semanage fcontext -a -t container_file_t "/sys/fs/ceph/montmp(/.*)?"

   restorecon -Rv /sys/fs/ceph/montmp
