通过ftp将我的本地主机与我的服务器同步

Question

我想实时和自动地将我的本地主机（Windows）与我的远程服务器同步。所以当我修改，创建或删除一个文件时，这个工具应该自动更新远程服务器。这个应用必须保持两个服务器实时同步。请我真的需要你的帮助。我试过FTPbox，但它并不总是更新，我需要更好的。我正在研究Windows，但是如果存在一些在Linux上更好。

感谢

Answer 1

尝试Dropbox或Google Drive如果你并不需要太多的信息同步。

Answer 2

我假设你想同步数据库和文件。这是我的出路，我希望这会对某人有所帮助。

第一个代码是本地代码，另一个代码是远程代码。

//make sure you are connected to your local database 

<?php 

//function to check internet connection. 

function is_connected() { 
    if($connected = fsockopen("www.example.com", 80)){ 
    // website, port (try 80 or 443) 
    if ($connected){ 
    $is_conn = true; //action when connected 
    fclose($connected); 
    } 

return $is_conn; 

} else { 
    $is_conn = false; //action in connection failure 
    } 
} 

//if connected to internet, do the following... 
if(is_connected()== true){ 

    echo "connected"; 

    ini_set('max_execution_time', 3000);//increase this incase of slow internet 

$table_name = TableName::find_all(); 
//whatever way you find an array 
//of all your entries on this particular 
//table that you want to sync with the remote table. 

$file = 'to_upload_local.php'; //a local file to put table contents into 
$current = serialize($table_name);//serialize the table contents (google). 
file_put_contents($file, $current);//put the serialized contents to the file. 

$remote_file = 'public_html/to_upload_remote.php';//this is the file that is on the remote server that you want to overwrite with the local file to upload. 

$ftp_server = "ftp.yourwebsite.org";// your ftp address 

// set up basic connection 
$conn_id = ftp_connect($ftp_server); 

// login with username and password 
$login_result = ftp_login($conn_id, "yourFTPUsername", "yourFTPPassword"); 

// turn passive mode on 
ftp_pasv($conn_id, true); 

// upload a file 
if (ftp_put($conn_id, $remote_file, $file, FTP_ASCII)){ 
    echo "Upload Successful"; 
} else { 

} 

// close the connection 
ftp_close($conn_id); 

//this script called below is to update your remote database. Its in the next example 

$call_script = file_get_contents('http://path_to_your_script'); 
} else { 
//if not connected to internet,.... 
echo "offline"; 
} 
?> 

在线脚本应该做的工作，应该是这个样子（你在前面的代码的最后一行称为一个）：

//make sure you're connected to remote database 
<?php 

//this function should compare num_rows of your two 
//databases values (local remote) and return the 
//difference. It's used with array_udiff function. 
function compare_objects($obj_a, $obj_b) { 
    return $obj_a->id - $obj_b->id; 
} 
//this function should compare contents of your two 
//databases values (local remote) and return the 
//difference. It's used with array_udiff function. 
function comparison($obj_a, $obj_b){ 
    if ($obj_a==$obj_b){ 
    return 0; 
    }else{ 
    return -1; 
    } 
} 


$file = '../to_upload_remote.php';//the uploaded file 
$current = file_get_contents($file);//load the file 
$array = unserialize($current);//unserialize to get the object array 
$remote_table_name = remote_table_name::find_all();//get what you have in 
//remote database 

//if a new value is added, create a new entry to database with new vals 
if($try_new = array_udiff($array, $remote_table_name, 'compare_objects')){ 
    foreach($try_new as $entry){ 
    $remote_table_name = new remote_table_name(); 
    $remote_table_name->value = $entry->value; 
    //depending on the number of your columns, 
    //add values to remote table that were not there before. 
    //you can use any other suitable method to do this. 
     if($remote_table_name->save()){ 
      echo "the remote_table_name was saved successfully"; 
     } 
    } 
} else { 
    echo "same number of rows"; 
} 

//if some values are changed, update them with new vals 
if($try_change = array_udiff($array, $remote_table_name, 'comparison')){ 
    foreach($try_change as $entry){ 
    $remote_table_name = remote_table_name::find_by_id($entry->id); 
    $remote_table_name->value = $entry->value; 
    //depending on the number of your columns, 
    //update values to remote table. 
    //you can use any other suitable method to do this. 
    if($remote_table_name->save()){ 
     echo "the remote_table_name was saved successfully"; 
    } 
    } 
} else { 
    echo "All values match"; 
} 

?> 

所以，任何时候，第一个代码它读取本地表，获取所有值并将它们放入本地文件，上传本地文件并替换远程文件夹中的一个，调用远程脚本来检查未序列化的本地表并将其与在线表进行比较，然后做必要的。
