使用查询而不使用mysqldump备份数据库

问题描述

我想将数据库转储到文件中.

I'd like to dump my databases to a file.

某些网站主机不允许远程或命令行访问，因此我必须使用一系列查询来做到这一点.

Certain website hosts don't allow remote or command line access, so I have to do this using a series of queries.

所有相关问题都说使用mysqldump"，这是一个很棒的工具，但是我没有命令行访问此数据库.

All of the related questions say "use mysqldump" which is a great tool but I don't have command line access to this database.

我希望同时创建CREATE和INSERT命令-与mysqldump基本上具有相同的性能. SELECT INTO OUTFILE是正确的出行之路，还是我在忽略其他东西-也许这不可能?

I'd like CREATE and INSERT commands to be created at the same time - basically, the same performance as mysqldump. Is SELECT INTO OUTFILE the right road to travel, or is there something else I'm overlooking - or maybe it's not possible?

推荐答案

使用mysqldump-php纯PHP解决方案复制mysqldump可执行文件的功能以解决从基本到中等的复杂性用例-我知道您可能没有远程CLI和/或mysql直接访问，但是只要您可以通过HTTPd请求在主机上的httpd上执行，它就可以工作:

Use mysqldump-php a pure-PHP solution to replicate the function of the mysqldump executable for basic to med complexity use cases - I understand you may not have remote CLI and/or mysql direct access, but so long as you can execute via an HTTP request on a httpd on the host this will work:

因此，您应该能够直接在/www/的安全目录中直接运行以下纯PHP脚本，并在其中写入输出文件，并使用wget进行抓取.

So you should be able to just run the following purely PHP script straight from a secure-directory in /www/ and have an output file written there and grab it with a wget.

mysqldump-php-GitHub上的纯PHP mysqldump

PHP示例:

<?php
require('database_connection.php');
require('mysql-dump.php')
$dumpSettings = array(
    'include-tables' => array('table1', 'table2'),
    'exclude-tables' => array('table3', 'table4'),
    'compress' => CompressMethod::GZIP, /* CompressMethod::[GZIP, BZIP2, NONE] */
    'no-data' => false,
    'add-drop-table' => false,
    'single-transaction' => true,
    'lock-tables' => false,
    'add-locks' => true,
    'extended-insert' => true
);

$dump = new MySQLDump('database','database_user','database_pass','localhost', $dumpSettings);
$dump->start('forum_dump.sql.gz');
    ?>
