细节

dumpBackup.php将创建一个用于导出或备份的XML文档,这个XML将包含wiki的页面内容(甚至是页面历史内容)。但是它不会对wiki的数据库进行备份,也就是说它不会备份帐户、图片、日志等等。[1] Once the dump is completed, you can import the XML dump.

例子

首先给你要用做备份的XML起一个名字。

例如你要保存一个完整的页面信息(使用--full),并将其命名为dump.xml

php dumpBackup.php --full > dump.xml
你可以在详细例子查看关于dump.xml的例子。

You can restrict the data dump to one namespace. In this example there are only templates:

php dumpBackup.php --current --filter=namespace:10 > templates.xml

To include multiple namespaces:

php dumpBackup.php --current --filter=namespace:10,11 > templates_plus_template_talk.xml

Example usage of a plugin:

php dumpBackup.php \
  --plugin=AbstractFilter:extensions/ActiveAbstract/AbstractFilter.php \
  --current \
  --output=gzip:/dumps/abstract.xml.gz \
  --filter=namespace:NS_MAIN \
  --filter=noredirect \
  --filter=abstract

php dumpBackup.php \
  --plugin=MathMLFilter:../extensions/MathSearch/maintenance/MathMLFilter.php \
  --current  \
  --filter=namespace:NS_MAIN \
  --filter=mathml

The --stub option can be used with dumpTextPass.php .

To --include-files:

php dumpBackup.php \
  --full \
  --include-files \
  --uploads \
  --output=gzip:/dumps/abstract.xml.gz

The --uploads option needs to be used also. Otherwise no files will be included.

详细例子

在案例中原谅色的文本是你需要输入的

  1. 首先使用cd指令 cd 跳转到你的maintenance文件夹,但注意你的文件路径可能和这个不同,以实际情况为准。
  2. 然后输入php dumpBackup.php --full > dump.xml,按下回车,你就会看到类似于这种一大堆代码蹦出来:
dump.xml文件被创建在maintenance文件夹里

选项

From MediaWiki r105912:

This script dumps the wiki page or logging database into an
XML interchange wrapper format for export or backup.

XML output is sent to stdout; progress reports are sent to stderr.

Usage: php dumpBackup.php <action> [<options>]
Actions:
  --full      Dump all revisions of every page.
  --current   Dump only the latest revision of every page.
  --logs      Dump all log events.
  --stable    Stable versions of pages?
  --pagelist=<file>
			  Where <file> is a list of page titles to be dumped
  --revrange  Dump specified range of revisions, requires
              revstart and revend options.
Options:
  --quiet     Don't dump status reports to stderr.
  --report=n  Report position and speed after every n pages processed.
			  (Default: 100)
  --server=h  Force reading from MySQL server h
  --start=n   Start from page_id or log_id n
  --end=n     Stop before page_id or log_id n (exclusive)
  --revstart=n  Start from rev_id n
  --revend=n    Stop before rev_id n (exclusive)
  --skip-header Don't output the <mediawiki> header
  --skip-footer Don't output the </mediawiki> footer
  --stub      Don't perform old_text lookups; for 2-pass dump
  --uploads   Include upload records without files
  --include-files Include files within the XML stream
  --conf=<file> Use the specified configuration file (LocalSettings.php)

  --wiki=<wiki>  Only back up the specified <wiki>

Fancy stuff: (Works? Add examples please.)
  --plugin=<class>[:<file>]   Load a dump plugin class
  --output=<type>:<file>      Begin a filtered output stream;
                              <type>s: file, gzip, bzip2, 7zip
  --filter=<type>[:<options>] Add a filter on an output branch
  --7ziplevel=<0-10>          Level of 7zip compression (0 - no compression is default)

This script connects to the database using the username and password defined by $wgDBadminuser and $wgDBadminpassword , which are normally set in LocalSettings.php . Although AdminSettings.php is obsolete, it can use the username and password set in that file too. Usually $wgDBadminuser is a user with more privileges than the one in $wgDBuser , but for running dumpBackup.php no extra privileges are required, so the usernames and passwords may be the same. If the variables are not set, dumpBackup.php will fail when trying to connect to the database:

$ php dumpBackup.php --full
DB connection error: Unknown error

备注

The XML file is sent to standard output (stdout); progress reports are sent to standard error (stderr). These are the default output and the output device for errors. When you call the script from the shell, then both outputs should by default be sent to the shell, meaning: You should see "informational" output and errors directly on screen.

错误代码

If you are not in the correct folder, you will receive this message:

No input file specified.

The dumpBackup script says "Warning: Division by zero in [DIRECTORY]/maintenance/backup.inc" when the parameter after "--report" evaluates as 0 or not-a-number. The fix is to run dumpBackup without the "--report" option; then dumpBackup will print a status line every 100 pages processed.

Recommended configuration settings

  • $wgRevisionCacheExpiry should be set to 0, to avoid inserting all revisions into the object cache. Most of them won't benefit from being stored in the cache because your readers normally won't view random old revisions of pages on your wiki.
