PAM和google模块双因子安全验证 时间同步chrony 自动安装系统Cobbler荐

# 1、PAM和google模块实现ssh双因子安全验证
**pam_google_authenticator模块**
功能:实现SSH登录的两次身份验证,先验证APP的数字码,再验证root用户的密码,都通过才可以登
录。目前只支持口令验证,不支持基于key验证
官方网站:http08年奥运会s://github.com/google/google-authe入口的英文nticidmator-andro2021年是什么年id
范例:
1、 在手机应用市场搜索:身份验证器或authenticator,并安装APP
2、 运行脚本(需要联网EPEL源),本质是修改了/etc/p指令由哪两部分组成am.d/sshd文件,将google的PAM模块加入进去实

# 2、时间同步服务
加密和安全当前都离不开时间的同步,否则各种网络服务可能不能正常运行 。
**时间同步服务**
多主机协作工作时,各个主机的时间同步很重要,时间不一致会造RAC成很多重要应用的故障,如:加密协
议,日志,集群等, 利用NTP(Network Time Protocol) 协议使网络中的各个计算机时间达到同步。
目前NTP协议属于运维基础架构中必备的基本服务之一
时间同步软件实现:
- ntp
- chr基础会计ony
**ntp**:
将系统时钟和世界协调时UTC同步,精度在局域网内可达0.1ms,在互联网上绝大多数的地方精度可以
达到1-50ms
项目官网:http://www.ntp.org
chrony:
实现NTP协议的的自由软件。可使系统时钟与NTP服务器,参考时钟(例如GPS接收器)以及使用手表
和键盘的手动输入进行同步。还可以作为NTPv4(RFC 5905)服务器和对等体运行,为网络中的计算机
提供时间服务。cron在线生成器设计用于在各种条件下良好递归函数运行,包括间歇性和高度拥挤的网络连接指令,温度变化(计算
机时钟对温度敏感),以及不能连续运行或在虚拟机上运行的系统。
通过Internet同步的两台crontab机器之间的典型精度在几毫秒之内同步器,在L博蓝共享AN上递归是什么意思,精度通常为几十微秒。利用硬
件时间戳或硬件参考时钟,可实现亚微秒的精度 。
## 2.1 使用idchrony实现内网时间等级赋分同步(一指令助手台node1从外网同步时间,其余0818团线报机器从node1同步时间)
```bash
#修改chrony.conf文件

# 3、利用cobbler实现系统自动化安装
## 3.1 Cobbler简介
- Cobbler是一款Linux生态的自动化运维工具等级保护,基于Python2开发,crontab定时任务配置用于自动化批量部署安装操作系统;其提供基于CLI的管理方式和WEB配置界面,其中WEB配置界面是基于Python2和Django框架开发。另外,cobbler还提供了API,方便二次开发。Cobbler属于C/S模型(客户端/服务器模型)
- Cobbler主要用于快速网络传统安装l作用域inux操作系统,支持众多的Linux发行版如:Red Hat、Fedor安装宽带a、CentOS、Debian、Ubuntu和SuSE等,甚至支持windows的安装
- Cobbler实质是PXE的二次封装,将多种安装参数封装到一起,并提供统一的管理方法
## 3.2 Cobbler相关服务当选
- 使用Cobbler安装系统需要一台专门提供各种服务递归函数python的服务器,提供的服务包括(HTTP/FTP/NFS,TFTP,DHCP),也可以将这几个服务分别部署到不同服务器。事同步卫星实上在实际应用中,总是将不同的服务分别部署到专门的服务器 。
- Cobbler是在HTTP、TFTP、DHCP等各种服务的基础上进行相关操作的,实际安装的大体过程类似于基于PXE的网络安装:客户端(裸机)开机使用网卡引导启动,其请求DHCP分配一个地址后从TFTP服务器获取启动文件,加载到客户端本地内存中运行,并显示出可安装的系统列表;在人为的选定安装的操作系统类型后,客服金融行业端会到HTTP服务race什么意思器下载相应的系统安装文件并执行自动安装
## 3.3 Cobbler工作原理
- client裸机配置了从网络启动后,开机后会广等级播包请求DHCP服务器(cobbler server)发送其分配好的一个IP
- DHCP服务器(cobbler ser同步卫星ver)收到请求后发送rnginx.pidesponese,包括其i龚俊p地址
- client裸机拿到ip后再向cobb挨的多音字组词ler server发送请求OS引导文件的请求
-递归函数 cobbl递归调用er server告诉裸机OS引导文件的名字和TFTP server的ip和port
- client裸机通过上面告知的TFTP server地址通信,下载引导文件
- client裸机执行执行该引导文件,确定加载信息,选择要安装的os,期间会再向cobbler server请求kickstart文件和os image
- cobbler server发送请求的kickstart和os iamge
- client裸机加载kickstart文件
- client裸机接收os image,安装该os image
## 3.4 安装Cobbler及相关48岁例假来了老不干净服务和组件
Cobbler所依赖的服务包括HTTPD,TFTP,DHCP等,如果有web入口生津是什么意思界面要求,还需要安装相关的组件
CentOS 8目前还没有提供Cobbler相关包
```bash
[root@centos7 ~]#yum -y install dh安装空调cp cobbler cob当选村书记的9个条件bler-web pyki作用ckstart
[root@centos7 ~]#sy金融行业stemctl enable --now cobbler httpd tftp dhcpd
```
相关包说明:
- httpd:提供yum源,并配合cobbler-web使得co传统bbler可以通过web网页界面进行配置管理
- tftp-se龚俊rvergithub中文官网网页:提供启动和菜单等相关文件网络下载功能
- cobbler-web : 提供基于web的cobbler管理界面
- pykickstart.noarch : 基于python的管理kickstart文件的库
说明:
- Cobbler依赖于eidiotpel传统的英文源,在安装cobbler之前需要配置epel源
- 在安装cobbler时会因为依赖而安装httpd,tftp-server相关包

The following are potential configuration items that you may want to fix:
1 : The 'server' field in /etc/cobbler/settings must be set to something other

2 : For PXE to be functional, the 'next_server' field in /etc/cobbler/settings

## 3.10 CentOS315打假都检查一些什么内容 7 基于cobbler实现系统的自动化安装
### 3.作用10.1 环境准备
两台主机
一台主机:CentOS 7 充当 Cobbler,httpremark,dhcp,tftp 服务器,并关闭防火crontab定时任务配置墙和SELinux
一台主机:充当测试机,用于实现自动化安装Linux系统
网络要求:关闭Vmware软件中的NAT模式中的传统文化有哪些内容DHCP服务,两个315记者成卧底公司二把手主机网卡基于NAT模式
### 3.10.2 配置eperacel仓库源
