Как выполнить команды SSH через PHP

Я бы использовал phpseclib, чистую реализацию PHP SSH . Пример:

 <?php include('Net/SSH2.php'); $ssh = new Net_SSH2('www.domain.tld'); if (!$ssh->login('username', 'password')) { exit('Login Failed'); } echo $ssh->exec('pwd'); echo $ssh->exec('ls -la'); ?> в <?php include('Net/SSH2.php'); $ssh = new Net_SSH2('www.domain.tld'); if (!$ssh->login('username', 'password')) { exit('Login Failed'); } echo $ssh->exec('pwd'); echo $ssh->exec('ls -la'); ?> 

У вас есть расширение SSH2?

Документы: http://www.php.net/manual/en/function.ssh2-exec.php

 $connection = ssh2_connect('shell.example.com', 22); ssh2_auth_password($connection, 'username', 'password'); $stream = ssh2_exec($connection, '/usr/local/bin/php -i'); 

Мне было сложно с ssh2 в php в основном потому, что поток вывода иногда работает, а иногда нет. Я просто собираюсь вставить свою библиотеку здесь, которая работает для меня очень хорошо. Если в коде есть небольшие несоответствия, это связано с тем, что я подключен к нему, но вы должны его портировать:

 <?php class Components_Ssh { private $host; private $user; private $pass; private $port; private $conn = false; private $error; private $stream; private $stream_timeout = 100; private $log; private $lastLog; public function __construct ( $host, $user, $pass, $port, $serverLog ) { $this->host = $host; $this->user = $user; $this->pass = $pass; $this->port = $port; $this->sLog = $serverLog; if ( $this->connect ()->authenticate () ) { return true; } } public function isConnected () { return ( boolean ) $this->conn; } public function __get ( $name ) { return $this->$name; } public function connect () { $this->logAction ( "Connecting to {$this->host}" ); if ( $this->conn = ssh2_connect ( $this->host, $this->port ) ) { return $this; } $this->logAction ( "Connection to {$this->host} failed" ); throw new Exception ( "Unable to connect to {$this->host}" ); } public function authenticate () { $this->logAction ( "Authenticating to {$this->host}" ); if ( ssh2_auth_password ( $this->conn, $this->user, $this->pass ) ) { return $this; } $this->logAction ( "Authentication to {$this->host} failed" ); throw new Exception ( "Unable to authenticate to {$this->host}" ); } public function sendFile ( $localFile, $remoteFile, $permision = 0644 ) { if ( ! is_file ( $localFile ) ) throw new Exception ( "Local file {$localFile} does not exist" ); $this->logAction ( "Sending file $localFile as $remoteFile" ); $sftp = ssh2_sftp ( $this->conn ); $sftpStream = @fopen ( 'ssh2.sftp://' . $sftp . $remoteFile, 'w' ); if ( ! $sftpStream ) { // if 1 method failes try the other one if ( ! @ssh2_scp_send ( $this->conn, $localFile, $remoteFile, $permision ) ) { throw new Exception ( "Could not open remote file: $remoteFile" ); } else { return true; } } $data_to_send = @file_get_contents ( $localFile ); if ( @fwrite ( $sftpStream, $data_to_send ) === false ) { throw new Exception ( "Could not send data from file: $localFile." ); } fclose ( $sftpStream ); $this->logAction ( "Sending file $localFile as $remoteFile succeeded" ); return true; } public function getFile ( $remoteFile, $localFile ) { $this->logAction ( "Receiving file $remoteFile as $localFile" ); if ( ssh2_scp_recv ( $this->conn, $remoteFile, $localFile ) ) { return true; } $this->logAction ( "Receiving file $remoteFile as $localFile failed" ); throw new Exception ( "Unable to get file to {$remoteFile}" ); } public function cmd ( $cmd, $returnOutput = false ) { $this->logAction ( "Executing command $cmd" ); $this->stream = ssh2_exec ( $this->conn, $cmd ); if ( FALSE === $this->stream ) { $this->logAction ( "Unable to execute command $cmd" ); throw new Exception ( "Unable to execute command '$cmd'" ); } $this->logAction ( "$cmd was executed" ); stream_set_blocking ( $this->stream, true ); stream_set_timeout ( $this->stream, $this->stream_timeout ); $this->lastLog = stream_get_contents ( $this->stream ); $this->logAction ( "$cmd output: {$this->lastLog}" ); fclose ( $this->stream ); $this->log .= $this->lastLog . "\n"; return ( $returnOutput ) ? $this->lastLog : $this; } public function shellCmd ( $cmds = array () ) { $this->logAction ( "Openning ssh2 shell" ); $this->shellStream = ssh2_shell ( $this->conn ); sleep ( 1 ); $out = ''; while ( $line = fgets ( $this->shellStream ) ) { $out .= $line; } $this->logAction ( "ssh2 shell output: $out" ); foreach ( $cmds as $cmd ) { $out = ''; $this->logAction ( "Writing ssh2 shell command: $cmd" ); fwrite ( $this->shellStream, "$cmd" .

Используйте функции ssh2 . Все, что вы делаете с помощью вызова exec (), может выполняться непосредственно с помощью этих функций, сохраняя при этом множество соединений и вызовы оболочки.
