1 安装包和配置服务

root:~# yum install cobbler  dhcp -y
root:~# systemctl enable tftp dhcpd httpd cobblerd
root:~# systemctl start tftp  httpd cobblerd

2 修改cobbler 配置文件

vim /etc/cobbler/settings
server: cobblerIP  384

next_server: cobblerIP 272

default_password_crypted: "$1$VBqc7U0W$F2qhI5oZwR8chJBU.mAly1"   101

manage_dhcp: 1    242 #可自动配置dhcp

现在已经可以自动化安装了，不过cobbler默认配置文件为最小化安装，想要自定义的花要修改配置文件

Centos 7.0下使用system-config-kickstart

修改CentOS-Base.repo

[base]                     修改 ---------->[development]  
name=CentOS-$releasever - Base
root:~# yum install -y system-config-kickstart.noarch
root:~  # env LANG=zh_CN.UTF-8 system-config-kickstart #生成自定义配置文件

将ks文件和系统关联，生成启动菜单

cobbler profile add --name=Centos6_mini --distro=Centos-6.10-x86_64 --kickstart=/var/lib/cobbler/kickstarts/ks6mini.cfg

将所有选项选完即可左上角保存

SpringBoot集成FastDFS+Nginx整合基于Token的防盗链

为什么要用SpringBoot? SpringBoot是由Pivotal团队提供的全新框架，其设计目的是用来简化新Spring应用的初始搭建以及开发过程。该框架使用了特定的方式来进行配置，从而使开发人员不再需要定义样板化的配置。通过这种方式，Spring Boot致力于在蓬勃发展的快速应用开发领域(rapid application development)成为领导者。创建独立的Spring应用程序嵌入的Tomcat，无需部署WAR文件简化Maven配置自动配置Spring 提供生产就绪型功能，如指标，健康检查和外部配置绝对没有代码生成并且对XML也没有配置要求为什么要用Nginx? 概述 Nginx（engine x）是一个开源的，支持高并发的www服务和代理服务软件。Nginx是俄罗斯人Igor Sysoev开发的，最初被应用到俄罗斯的大型网站（www.rambler.ru）上。后来作者将源代码以类BSD许可证的形式开源出来供全球使用。在功能应用方面，Nginx不仅是一个优秀的Web服务软件，还具有反向代理负载均衡和缓存的功能。在反向代理负载均衡方面类似于LVS负载均衡...

文件共享是在企业办公网络中经常用到的一项功能，如何设置并使用文件共享在技术上并不复杂，其中的问题主要集中在权限配置方面。本文以世界技能大赛网络系统管理赛项中的一道题目作为案例，详细分析了如何利用Samba服务结合系统权限来完成各种复杂的权限设置，本文所采用的系统版本为CentOS7。 1. 任务需求与分析将/share/archive目录创建为samba共享，并完成下列要求：① 共享名为archive；② zhangsan，lisi，wangwu用户都能通过输入用户名和密码（Skills39）登录并上传文件；③ 其他人不能访问共享目录；④ zhangsan能够查看和删除所有人的文件；⑤ lisi能够查看所有人的文件，但不能删除别人的文件；⑥ wangwu只能查看和删除自己的文件，不能查看和删除别人的文件；在这6项需求中，第1、2、3项需求属于Samba服务的常规配置，实现起来较为简单；第4、5、6项需求主要是针对不同用户的权限设置，需要结合系统权限完成配置，实现起来较为复杂。下面就从这两个方面分别进行分析。 2. Samba常规配置在CentOS7系统中所提供的Samba版本为4....
