Manual:DumpBackup.php/zh

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）. DumpBackup.php does not create a full backup of the wiki database, the dump does not contain user accounts, images, edit logs, deleted revisions, etc. Once the dump is completed, you can import the XML dump.

General examples
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


 * 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 with their current revision:

or templates with all of their revisions:

To include multiple namespaces:

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 \ --quiet

或

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

The  option can be used with.

To  :

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

The   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文件已经被创建在maintenance文件夹里了，你也许需要刷新一下你的SCP传输工具才会看到它.

选项
来自MediaWiki ：

 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 [ ] 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= Where 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 header --skip-footer Don't output the 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= Use the specified configuration file (LocalSettings.php)

--wiki= Only back up the specified

Fancy stuff: (Works? Add examples please.) --plugin= [: ]  Load a dump plugin class --output= :     Begin a filtered output stream; s: file, gzip, bzip2, 7zip --filter= [: ] 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 and, which are normally set in. Although 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, but for running  no extra privileges are required, so the usernames and passwords may be the same. If the variables are not set,  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 " " 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

 * 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.
