php遠程copy以及執行命令

編輯：關於PHP編程

php遠程copy文件以及在遠程服務器中執行命令時，所用到的模塊是ssh2，以後所有的操作都依據ssh2連接句柄完成。

1. SSH2模塊的安裝
1.1 安裝需要的擴展包

[plain]
wget
tar zxf libssh2-1.4.2.tar.gz
cd libssh2-1.4.2
./configure && make && make install

wget
tar zxf libssh2-1.4.2.tar.gz
cd libssh2-1.4.2
./configure && make && make install

[plain]
wget
cd ssh2-0.11.3
phpize (如果報錯命令沒有找到，apt-get install php5-dev)
./configure —with-ssh2 && make && make install

wget
cd ssh2-0.11.3
phpize (如果報錯命令沒有找到，apt-get install php5-dev)
./configure —with-ssh2 && make && make install
1.2 修改php配置信息

[plain]
cd /etc/php5/cgi
vim php.ini
添加項：extension=/usr/lib/php5/20090626/ssh2.so
ssh2.so是編譯ssh2時得到的模塊，上面是模塊的位置。

cd /etc/php5/cgi
vim php.ini
添加項：extension=/usr/lib/php5/20090626/ssh2.so
ssh2.so是編譯ssh2時得到的模塊，上面是模塊的位置。

[plain]
cd /etc/php5/cli
vim php.ini
添加項：extension=/usr/lib/php5/20090626/ssh2.so
ssh2.so是編譯ssh2時得到的模塊，上面是模塊的位置。

cd /etc/php5/cli
vim php.ini
添加項：extension=/usr/lib/php5/20090626/ssh2.so
ssh2.so是編譯ssh2時得到的模塊，上面是模塊的位置。
1.3 重啟web服務器

[plain]
/etc/init.d/lighttpd restart

/etc/init.d/lighttpd restart
1.4 查看是否加載了ssh2

[plain]
[root@localhost ~]php -m | grep ssh2
ssh2

[root@localhost ~]php -m | grep ssh2
ssh22. SSH2模塊的連接應用
SSH2連接有兩種方式，分別是用戶名密碼，ssh密鑰形式。

2.1 用戶名與密碼

[php]
$connection = ssh2_connect("192.168.6.222",22);
if (ssh2_auth_password($connection,"veno","ubuntu"))
{
echo "Authentication Successful! ";
}else{
die("Authentication Failed...");
}

$connection = ssh2_connect("192.168.6.222",22);
if (ssh2_auth_password($connection,"veno","ubuntu"))
{
echo "Authentication Successful! ";
}else{
die("Authentication Failed...");
}
2.2 ssh密鑰

[php]
$connection = ssh2_connect('192.168.6.222', 22, array('hostkey'=>'ssh-rsa'));
if (ssh2_auth_pubkey_file($connection, 'root',
                          '/root/.ssh/id_rsa.pub',
                          '/root/.ssh/id_rsa'))
{
   echo "Public Key Authentication Successful\n";
} else {
     echo ('Public Key Authentication Failed');
}

$connection = ssh2_connect('192.168.6.222', 22, array('hostkey'=>'ssh-rsa'));
if (ssh2_auth_pubkey_file($connection, 'root',
                          '/root/.ssh/id_rsa.pub',
                          '/root/.ssh/id_rsa'))
{
   echo "Public Key Authentication Successful\n";
} else {
   echo ('Public Key Authentication Failed');
}

Ps: 密鑰生成：

在服務器192.168.6.229上面以root登錄

[plain]
#ssh-keygen

#ssh-keygen
有什麼提問基本上回車即可

後成的公鑰在~/.ssh/id_rsa.pub

如果想在229通過密鑰驗證登錄到222上面，則把229的公鑰id_rsa.pub cp到222上面，先手動登錄root，然後運行：

[plain]
cat id_rsa.pub >> ~/.ssh/authorized_keys

cat id_rsa.pub >> ~/.ssh/authorized_keys
這樣就可以在229上面ssh 192.168.6.229不需要輸入密碼即可登錄到222。上面php代碼在229上面也可以通過驗證。

3. SSH2模塊的具體應用
通過SSH2驗證通過後，得到的連接符為$connection

3.1 實現遠程copy文件
遠程服務器文件copy到本地:

bool ssh2_scp_recv ( resource $session, string $remote_file, string $local_file )

Ps: 接收文件時，後面文件名可以為空，如：

[php]
ssh2_scp_recv($connection, '/home/xiaozl/veno1.exe', '/home/xiaozl/')

ssh2_scp_recv($connection, '/home/xiaozl/veno1.exe', '/home/xiaozl/')

本地文件copy到遠程服務器

bool ssh2_scp_send ( resource $session, string $local_file, string $remote_file [, int $create_mode] )

Ps:發送文件時，後面的文件名不能為空，如：

[php]
ssh2_scp_send($connection, '/home/xiaozl/package.xml', '/home/xiaozl/package.xml');

ssh2_scp_send($connection, '/home/xiaozl/package.xml', '/home/xiaozl/package.xml');

3.2 執行遠程服務器上的命令並取返回值
resource ssh2_exec( resource $session, string $command [, string $pty [, array $env [, int $width [, int $height [, int $width_height_type]]]]] )

在229上面執行222上的命令具體實例:

[php]
$tcmd="cd /home/veno/gateway/radiusclient;";
$tcmd.="./nastool.sh get-status app=2b1c5364-db39-c76d-842c-11d4a81d555d";
$stream = ssh2_exec($connection, $tcmd);
stream_set_blocking($stream,true);
echo stream_get_contents($stream);

$tcmd="cd /home/veno/gateway/radiusclient;";
$tcmd.="./nastool.sh get-status app=2b1c5364-db39-c76d-842c-11d4a81d555d";
$stream = ssh2_exec($connection, $tcmd);
stream_set_blocking($stream,true);
echo stream_get_contents($stream);

 '/root/.ssh/id_rsa'))
