用一个数据库和一个代码库管理多个WordPress站点

Posted 2021-02-27

This is a simple but powerful tweak to the wp-config.php file that will make it easy to run multiple websites using one database and codebase. Simply change "yourdomain.com" with your domain and that's it. Repeat that line for new domains.

// You can have multiple installations in one database if you give each a unique prefix
 
$domain_list = array();
 
// auto database name
$domain_list["yourdomain.com"] = "";\
 
$domain_name = preg_replace("/^www\./", "", $_SERVER["SERVER_NAME"]);
 
if (array_key_exists($domain_name, $domain_list))
{
	$table_prefix = $domain_list[$domain_name];
	if (!$table_prefix) { $table_prefix  = "wp_" . md5($domain_name); }
}
else
{
	print "Unknown error"; exit;
}
