我想實時和自動地將我的本地主機(Windows)與我的遠程服務器同步。所以當我修改,創建或刪除一個文件時,這個工具應該自動更新遠程服務器。這個應用必須保持兩個服務器實時同步。請我真的需要你的幫助。我試過FTPbox,但它並不總是更新,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。通過ftp將我的本地主機與我的服務器同步
感謝

感謝
嘗試Dropbox或Google Drive如果你並不需要太多的信息同步。
我假設你想同步數據庫和文件。這是我的出路,我希望這會對某人有所幫助。
第一個代碼是本地代碼,另一個代碼是遠程代碼。
//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
$call_script = file_get_contents('http://path_to_your_script');
} else {
//if not connected to internet,....
echo "offline";
}
?>
在線腳本應該做的工作,應該是這個樣子(你在前面的代碼的最後一行稱爲一個):
//make sure you're connected to remote database
<?php
//this function should compare num_rows of your two
//databases values (local remote) and return the
//difference. It's used with array_udiff function.
function compare_objects($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,任何時候,第一個代碼它讀取本地表,獲取所有值並將它們放入本地文件,上傳本地文件並替換遠程文件夾中的一個,調用遠程腳本來檢查未序列化的本地表並將其與在線表進行比較,然後做必要的。
如果你會做自動同步,你也會自動部署錯誤......不確定關於Windows - 但你可以使用[* cron *](http://www.adminschoice.com/crontab-quick -reference)在linux中安排一些東西運行,比如每分鐘。您可以將它與使用[* rsync *](http://rsync.samba.org/documentation.html)的shell腳本一起使用 – alfasin
