使用PhpMyAdmin同步数据库

标签： php mysql database phpmyadmin

我正在寻找一种方法，通过使用PhpMyAdmin在同步的不同环境（本地和生产）中同步MySql数据库。因此，寻找能够找到差异，然后应用我们想要的那个。

由于内置的​​同步功能已停止使用。在PhpMyAdmin中执行此操作的最佳方法是什么？

即使通过sql查询也可以。

感谢。

你可以很容易地在php中执行此操作...这是我使用的脚本

同步

$account_tables = $Db_stage->run("SELECT table_name, table_rows FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = '".$Init->container["Config"]->dbName."' ORDER BY table_name");
$production_tables = $Db_production->run("SELECT table_name, table_rows FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = '".$dbName."' ORDER BY table_name");

foreach ($account_tables as $account_table){        
    $dbDrop = "/usr/bin/mysql -u ".$Init->container["Config"]->dbUser." -p".$Init->container["Config"]->dbPassword." ".$Init->container["Config"]->dbName." -e 'drop table `".$account_table["table_name"]."`'";
    echo "DROP ".$account_table["table_name"]."<br/>";
    //echo $dbDrop."<br/>";
    exec($dbDrop);
    flush();
}

foreach ($production_tables as $production_table){
    echo "SETUP ".$production_table["table_name"].'<br/>';
    $dbDump = '/usr/bin/mysqldump --lock-tables=false --single-transaction --skip-add-locks -h '.$dbHost.' -u '.$dbUser.' -p'.$dbPassword.' '.$dbName.' '.$production_table["table_name"].' > '.$Init->container["Config"]->dirPublic.'system/sync/db/'.$production_table["table_name"].'.sql';
    //echo $dbDump."<br/>";
    exec($dbDump);
    exec('/usr/bin/mysql --user='.$Init->container["Config"]->dbUser.' --password='.$Init->container["Config"]->dbPassword.' '.$Init->container["Config"]->dbName.' < '.$Init->container["Config"]->dirPublic.'system/sync/db/'.$production_table["table_name"].'.sql');    
    flush();
}
