我想每天自動執行一個PHP腳本，它們會進行數據庫備份並將其發送到電子郵件。當我通過調用它的URL在我的Web瀏覽器中執行它時，這一切都很好。但是，當我確定我的服務器中的cron作業，我得到這個錯誤：如何在cron作業中執行php腳本
sh: /Viana-BackupMailer/mehravar_news_20161204_192302.sql.gz: No such file or directory mysqldump: Got errno 32 on write X-Powered-By: PHP/5.4.45 Content-type: text/html
我在cron作業使用下面的命令：
php /home/mehravar/public_html/Viana-BackupMailer.php
，這是我的PHP代碼：
<?php
$TimeZone = "Asia/Tehran"; // Your location time zone
$SiteName = "Mysite.com"; // Your site name
$SiteTitle = "My Site Title"; // Your site title
$DeleteBackup = false; // Delete Backup file after send it by email
$DB_Server = "localhost"; // MySQL server name
$DB_Name = "DB_Name"; // MySQL database name
$DB_Username = "DB_User"; // MySQL database Username
$DB_Password = "DB_Pass"; // MySQL database Password
$Mail_To = "[email protected]"; // Receiver email
$Mail_From = "[email protected]"; // Sender email (Your host email)
$LogText = "";
$StorageDir = "Viana-BackupMailer";
if(!is_dir($_SERVER['DOCUMENT_ROOT']."/".$StorageDir)){
mkdir($_SERVER['DOCUMENT_ROOT']."/".$StorageDir, 0755);
}
date_default_timezone_set($TimeZone);
$BackupDate = date("Ymd_His");
$LogDate = date("Ym");
$Path = $_SERVER["DOCUMENT_ROOT"]."/".$StorageDir."/";
$LogFile = $Path.$LogDate."_Viana-BackupMailer.log";
function WriteLog($LogText){
$Handle = fopen($GLOBALS['LogFile'], (file_exists($GLOBALS['LogFile'])) ? 'a' : 'w');
fwrite($Handle, " Viana-BackupMailer Log File \n");
fwrite($Handle, "================================================================================================\n");
fclose($Handle);
file_put_contents($GLOBALS['LogFile'], $LogText, FILE_APPEND | LOCK_EX);
}
$DB_BackupFile = ($DB_Name == "" ? "all_databases" : $DB_Name)."_$BackupDate.sql.gz";

請幫幫我。 謝謝。
