Backuppc安装与配置
Backup PC服务器数据备份方案作者：jason日期：2015-05-15企业服务器的数据都是非常重要的，为了确保安全，我们会做数据库备份，还要考虑应用数据及补丁备份，仅仅是本机备份是不够的，我们还要做异地备份。
服务器备份软件很多，有Amand a、Bacula、Burp，这里，我们只讨论B ackup PC来做备份服务器。
Backup PC是Li nux平台下一款非常灵活的开源备份工具，支持RSYN C、RSYNCD(Win平台使用，官方推荐)、SMB、SSH、NFS等多种传输工具，支持增量备份，可以跨目录树跨多次备份去重（md5验证，节省空间）等多种优点，支持web页面管理，有中文语言包。
它工作在pu ll模式下，服务器主动从客户机爬数据。
本文档工作环境： Centos 6.4X86_64最小化安装Backup PC 3.2（最新版本3.3），这里假设你会配置网络且熟悉简单的linux操作。
1.在BackupPC安装服务器上添加back uppc组及用户[root@backup pc ~]# groupa ddbackup pc[root@backup pc ~]# userad d -g backup pcbackup pc2.BackupPC没有在C ento s官方库中，我们使用第三方epel库，方法如下，根据自己的版本选择其一。

ansible：playbook详解
ansible：playbook详解Blog：概述playbook是由⼀个或者多个play组成的列表。
主要功能是将预定义的⼀组主机装扮成事先通过ansible中的task定义好的⾓⾊。
task实际是调⽤ansible的⼀个模块，将多个play组织在⼀个playbook中，即可以让它们联合起来，将事先编排的机制执⾏预定义的动作。
playbook⽂件是使⽤YAML语⾔编写的。
YAML语⾔官⽹：YAML(Yet another Markup Language，仍是⼀种标记语⾔)是⼀个可读性⾼的⽤来表达资料序列的格式。
⽬前很多软件采⽤了此格式，如ansible、docker、k8s等。
语法说明YAML 的配置⽂件后缀为.yml⼤⼩写敏感使⽤缩进表⽰层级关系缩进不允许使⽤tab，只允许空格缩进的空格数不重要，只要相同层级的元素左对齐即可#表⽰注释，从这个字符⼀直到⾏尾，都会被解析器忽略数据结构YAML ⽀持的数据结构有三种。
对象：键值对的集合，⼜称为映射（mapping）/ 哈希（hashes） / 字典（dictionary）数组：⼀组按次序排列的值，⼜称为序列（sequence） / 列表（list）纯量（scalars）：单个的、不可再分的值对象对象的⼀组键值对，使⽤冒号:结构表⽰。
例如：name: 'Rohn'Yaml 也允许另⼀种写法，将所有键值对写成⼀个⾏内对象。
例如：{ hash: { name: 'Steve', foo: 'bar' } }数组⼀组连词线-开头的⾏，构成⼀个数组。
例如：- Cat- Dog- Goldfish纯量纯量是最基本的、不可再分的值。
纯量的类型：字符串布尔值整数浮点数Null时间⽇期字符串字符串默认不使⽤引号表⽰。
如果字符串之中包含空格或特殊字符，需要放在引号之中。
单引号和双引号都可以使⽤，双引号不会对特殊字符转义。

anssible用法举例
anssible用法举例Ansible是一种自动化工具，它使用一种简单易懂的语法来部署、配置和编排IT 基础设施。
通过Ansible，我们可以实现以声明性的方式定义所需状态，并自动化地将系统从当前状态转移到所期望的状态。
本文将通过一系列实际示例，详细介绍Ansible的用法，帮助读者逐步学习和理解这一工具的应用。
第一步：安装Ansible在开始之前，我们需要先安装Ansible。
Ansible可以运行在任何支持Python 的操作系统上，例如Linux、macOS和Windows。
我们可以使用系统的包管理器来安装Ansible，也可以通过pip命令安装。
下面是在Ubuntu系统上安装Ansible的示例命令：sudo apt-get updatesudo apt-get install ansible安装完成后，可以使用`ansible version`命令验证Ansible是否正常安装。
第二步：编写Ansible配置文件Ansible使用YAML语法来编写配置文件，这些配置文件定义了我们需要执行的任务和目标系统的信息。
创建一个名为`ansible.cfg`的文件，输入以下内容：[defaults]inventory = hosts该配置文件指定了Ansible的默认配置，包括主机清单文件的位置。
在这个例子中，我们假设主机清单文件名为`hosts`，稍后将会创建该文件。
第三步：创建主机清单文件主机清单文件用于指定Ansible所管理的目标主机及其连接信息。
创建一个名为`hosts`的文件，输入以下内容：[webservers]web1 ansible_host=192.168.1.10web2 ansible_host=192.168.1.11[databases]db1 ansible_host=192.168.1.20db2 ansible_host=192.168.1.21在这个例子中，我们定义了两个组`webservers`和`databases`，并分别列出了每个组中的主机及其IP地址。

I immediately got down to carrying out my plan. Luckily, I contacted all the players in the photo. To my great delight, they were greatly touched by the plan and all agreed to join in. To make the scene real, I even managed to find all the basketball jerseys, equipment and arrange for a similar-looking basketball court. The big day finally came. After wheeling my grandpa to the court, we began the special game. While playing, I kept an eye on grandpa, waiting for something deep down.Seeing “the same players” playing there, grandpa seemed to have thought of something. Glancing at grandpa again, I found him cheering us on just like 20 years before. Sitting in the warm sunlight, he cheered and clapped, with a bigger smile. For a while, my mind seemed to flash back to those beautiful days. Indeed, my plan somewhat worked. I was overjoyed that I could do something to delight Grandpa, an important person in my 1ife. I was not sure whether this birthday would stick in his mind, but one thing was certain: it’d definitely stick in mine.应用文评分标准一、评分总则1、本题总分为15 分，按5 个档次给分。

php多站点配置以及ForbiddenYoudonthavepermissiontoacc。
php多站点配置以及Forbidden You don't havepermission to access / on this server问题解决⼀、总结⼀句话总结：我的问题是php的版本问题> php 版本> 改变因素找到问题的原因了，我把php的版本从5.4.45切换成了 5.6.27，切换回来之后就好了，php⽂件就能解析了，⽹站就能访问了和配置实在没有半⽑钱关系收获吧：仔细思考你做了哪些改变因素（在正确和错误之间），我忘记我切换了版本其实是我没有意识到php版本切换会造成⽹站⽆法访问的问题因为php⽂件本⾝就是靠服务器来解析的，php版本切换肯定有可能会造成⽹站⽆法访问1、apache 设置⽬录不可访问，具体⽬录下的⽂件可以访问？之前访问部分⽹站，会出现这种情况，如果没有具体的访问⽂件，就会默认跳转到根⽬录，这样很多⽂件会暴露。
所以要修改httpd.conf⽂件，Options Indexes FollowSymLinks修改为Options FollowSymLinks其实就是将Indexes去掉，Indexes表⽰若当前⽬录没有index.html就会显⽰⽬录结构2、apache+php配置多站点？> httpd.conf> httpd-vhosts.conf> hosts1. 在”C:\wamp\bin\apache\apache2.4.9\conf“⽬录下打开httpd.conf配置⽂件⼤概516⾏左右在找到# Virtual hosts#Include conf/extra/httpd-vhosts.conf把include 的注释去掉，让他去加载conf/extra/httpd-vhosts.conf⽂件2. 在”C:\wamp\bin\apache\apache2.4.9\conf\extra“⽬录打开httpd-vhosts.conf⽂件，直接在这⾥配置站点上⾯全部注释，第⼀句NameVirtualHost *:80（设置端⼝号）# #以下是⾃⼰配置的站点1< VirtualHost *:80 >ServerName (⽹站的域名)DocumentRoot “C:\wamp\www” （⽂件的路径）< Directory “C:\wamp\www” > （⽂件的路径）Options IndexesOrder allow,denyAllow from allSatisfy all< /Directory >< /VirtualHost >3.在“C:\Windows\System32\drivers\etc”的hosts⽂件⾥⾯配置就可以了⼆、php多站点配置以及Forbidden You don't have permission to access / on this server 问题解决问题⼀：前⼏天在电脑上配置多站点的后突然出现了：”You don’t have permission to access / on this server！“ 究其原因是：swampserver默认访问的是www⽂件夹的站点，不允许访问其他的站点。

After years of hard work，his dream has come true. The house is now in the early stages of building.Six years ago，Josh and his dad went into a Habitat for Humanity Restore，a home improvement store and donation center run by the nonprofit organization. They were there to buy a sink. Josh, then 11，also noticed a collection of pennies.“I instantly felt the urge to help out with that，”he said. Josh set a fundraising(筹款) deadline of four years. Many people doubted whether he could reach his goal of $100，000，but it didn't shake his faith. He raised money at his school and other nearby schools. He collected money from neighbors, got publicity from local newspapers，and placed cans in stores so that people could donate extra change.Josh's fundraising efforts began to produce results. Still, there were challenges. Four months before his deadline，he was $30，000 short. He decided to hold a Family Fun Fair and Spaghetti Dinner in Uxbridge，which is in the province of Ontario. The event raised $19，000.“I didn't care how long it took me，”Josh said.“I would raise $100，000.”With three weeks left，a company called Josh's house，offering to donate $18，000.Eventually，Josh reached a total of $124，000 before his deadline.“The momentum just kept going，and we decided to do more，”he said.“Josh's Penny House” is being built by Habitat for Humanity in the city of Oshawa，along with 24 new townhouses. Josh has helped with some of the construction，as have other volunteers. He will choose the family that moves into the unit.Next year，the 17-year-old will head to college in British Columbia，Canada's westernmost province. As a 11-year-old kid when starting fundraising，Josh was able to send a powerful message across the world. No matter how old you are，if you have a dream and are willing to do anything to achieve it，it can come true.1．Which word can best describe Josh Morrison in Paragraph 2?A．Straightforward. B．Openminded. C．Determined. D．Cautious.2．Why was the Family Fun Fair and Spaghetti Dinner event in Uxbridge held?A．To call for more attention. B．To attain his goal.C．To win approval from the locals. D．To find sponsors for a family.3．What does the underlined sentence in Paragraph 4 mean?A．His project became more popular. B．He received continuous donations.C．The result was beyond expectations.

extra_hosts用法
extra_hosts是Docker容器的一个参数，用于指定额外的主机名解析。
在Docker容器中，通常可以使用主机名来访问其他容器或主机。
然而有时候，我们可能需要在容器内部使用一些自定义的主机名，而这些主机名并不在DNS服务器中。
这时候，就可以使用extra_hosts参数来实现自定义主机名的解析。
extra_hosts参数的使用方法如下：
docker run命令中加入--add-host选项，其后跟随要添加的主机名和对应的IP地址，多个主机名可以用逗号分隔。
例如：
docker run --add-host=customhost:192.168.1.100 -itd myimage.
这将在运行容器时向其添加一个名为customhost的主机名，其对应的IP地址为192.168.1.100。
使用extra_hosts参数可以为容器添加自定义的主机名解析，这在一些特定的网络环境下可能会非常有用。
比如在一些内部网络测试中，可能需要模拟一些特定的主机名来进行测试，这时候extra_hosts就可以派上用场。
需要注意的是，extra_hosts参数只在容器运行时生效，不会对Docker宿主机的主机名解析产生影响。
另外，extra_hosts参数也可以在Docker Compose文件中使用，以实现对容器的自定义主机名解析。
总之，extra_hosts参数可以帮助我们在Docker容器中实现自定义的主机名解析，从而满足一些特定的网络环境需求。
希望这个回答能够帮助你理解extra_hosts参数的用法。
