php远程copy以及执行命令

php远程copy以及执行命令

php远程copy文件以及在远程服务器中执行命令时,所用到的模块是ssh2,以后所有的操作都依据ssh2连接句柄完成。

1. SSH2模块的安装

1.1 安装需要的扩展包

wget  http://www.libssh2.org/download/libssh2-1.4.2.tar.gz
tar zxf libssh2-1.4.2.tar.gz
cd libssh2-1.4.2
./configure && make && make install
Copy after login

wget  http://pecl.php.net/get/ssh2-0.11.3.tgz
cd ssh2-0.11.3
phpize   (如果报错命令没有找到,apt-get install php5-dev)
./configure ―with-ssh2 && make && make install
Copy after login

1.2 修改php配置信息

cd  /etc/php5/cgi
vim  php.ini
添加项:extension=/usr/lib/php5/20090626/ssh2.so
     ssh2.so是编译ssh2时得到的模块,上面是模块的位置。
Copy after login

cd  /etc/php5/cli
vim  php.ini
添加项:extension=/usr/lib/php5/20090626/ssh2.so
     ssh2.so是编译ssh2时得到的模块,上面是模块的位置。
Copy after login

1.3 重启web服务器

/etc/init.d/lighttpd restart
Copy after login

1.4 查看是否加载了ssh2

[root@localhost ~]php -m | grep ssh2
ssh2
Copy after login

2. SSH2模块的连接应用

SSH2连接有两种方式,分别是用户名密码,ssh密钥形式。

2.1 用户名与密码

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

2.2 ssh密钥

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

 

Ps: 密钥生成:

在服务器192.168.6.229上面以root登录

#ssh-keygen
Copy after login

有什么提问基本上回车即可

后成的公钥在~/.ssh/id_rsa.pub

如果想在229通过密钥验证登录到222上面,则把229的公钥id_rsa.pub cp到222上面,先手动登录root,然后运行:

cat id_rsa.pub >> ~/.ssh/authorized_keys
Copy after login

这样就可以在229上面ssh 192.168.6.229不需要输入密码即可登录到222。上面php代码在229上面也可以通过验证。

 

3. SSH2模块的具体应用

通过SSH2验证通过后,得到的连接符为$connection

3.1 实现远程copy文件

远程服务器文件copy到本地:

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

Ps: 接收文件时,后面文件名可以为空,如:

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


本地文件copy到远程服务器

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

Ps:发送文件时,后面的文件名不能为空,如:

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

 

3.2 执行远程服务器上的命令并取返回值

resource ssh2_exec( resource $session, string $command [, string $pty [, array $env [, int $width [, int $height [, int $width_height_type]]]]] )

在229上面执行222上的命令具体实例:

$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); 
Copy after login

附件:测试中应用到的php代码

<?php echo "是访问到这里来了";
$connection = ssh2_connect('192.168.6.222', 22, array('hostkey'=>'ssh-rsa'));
if (ssh2_auth_pubkey_file($connection, 'root',
                          '/root/.ssh/id_rsa.pub',
                          '/root/.ssh/id_rsa'))
{
  echo "Public Key Authentication Successful\n";
  //$flag=ssh2_scp_recv($connection, '/home/xiaozl/veno1.exe', '/home/xiaozl/');
  //接收时,后面文件名可以为空
  //$flag=ssh2_scp_send($connection, '/home/xiaozl/package.xml', '/home/xiaozl/package.xml');
  //发送时,后面的文件名不能为空
  //echo $flag;
  $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); 
} else {
  echo ('Public Key Authentication Failed');
}
echo "<br>";
$connection = ssh2_connect('192.168.6.222', 22);
ssh2_auth_password($connection, 'veno', '*******');
$tcmd="cd /home/veno/gateway/radiusclient;";
  $tcmd.="./nastool.sh get-status app=2b1c5364-db39-c76d-842c-11d4a81d555d";
  $stream = ssh2_exec($connection, $tcmd);
  echo "<br>";
  echo "-----------------------------------------------";
  stream_set_blocking($stream,true);
  echo stream_get_contents($stream); 
  echo "-----------------------------------------------";
echo "<br>";
Copy after login

Telnet in Windows 11 Complete Tutorial [Installation/Enablement and Troubleshooting] Telnet in Windows 11 Complete Tutorial [Installation/Enablement and Troubleshooting] May 22, 2023 pm 09:35 PM

&lt;p&gt;Telnet is the abbreviation of "Terminal Network". It is a protocol that users can use to connect one computer to a local computer. &lt;/p&gt;&lt;p&gt;Here, the local computer refers to the device that initiates the connection, and the computer connected to the local computer is called the remote computer. &lt;/p&gt;&lt;p&gt;Telnet runs on a client/server principal, and although it is outdated, it is still used by many people in 2022. Many people have already switched to Windows 11 operating system, which is the latest operating system offered by Microsoft. &

With the development of cloud computing and the Internet of Things, remote operation of servers has become increasingly important. In Python, we can use the Paramiko module to easily implement SSH remote operations. In this article, we will introduce the basic usage of Paramiko and how to use Paramiko in Python to remotely manage servers. What is Paramiko Paramiko is a Python module for SSHv1 and SSHv2 that can be used to connect and control SSH clients

OpenSSH on Windows: Installation, Configuration, and Usage Guide OpenSSH on Windows: Installation, Configuration, and Usage Guide Mar 08, 2024 am 09:31 AM

For most Windows users, Remote Desktop Protocol (RDP) has always been the first choice for remote management because it provides a friendly graphical interface. However, for system administrators who require more granular control, SSH may better suit their needs. Through SSH, administrators can interact with remote devices through the command line, which can make management work more efficient. The advantage of SSH is its security and flexibility, making it easier for administrators to perform remote management and maintenance work, especially when dealing with a large number of devices or performing automated tasks. So while RDP excels in terms of user-friendliness, for system administrators, SSH is superior in terms of power and control. Previously, Windows users needed to borrow

What does CONNECTION_REFUSED mean? What does CONNECTION_REFUSED mean? Jul 31, 2023 pm 02:48 PM

CONNECTION_REFUSED is a network connection error that usually occurs when trying to connect to a remote server. When a client device attempts to establish a network connection with a server, and the server rejects the connection request, a CONNECTION_REFUSED error is returned. Common reasons include: the server is not started, the server cannot accept more connection requests, the server firewall blocks the connection, etc.

How to solve connection error How to solve connection error Nov 07, 2023 am 10:44 AM

Solution: 1. Check the network connection; 2. Check the server status; 3. Clear the cache and cookies; 4. Check the firewall and security software settings; 5. Try to use other networks, etc.

Linux SSH login mutual trust configuration Linux SSH login mutual trust configuration Feb 19, 2024 pm 07:48 PM

1. The purpose of ssh mutual trust 1. SSH mutual trust is required when building a cluster, which is conducive to convenient operation on another node. 2. When using scp remote copy operation, you need to enter the user name and password of the target server. At this time, you can configure SSH mutual trust between Linux servers, so that you can log in without a password when operating between multiple Linux servers. 2. The principle of ssh mutual trust configuration. In short, the server stores the certificate of the target host so that authentication can be completed automatically without entering a password. 3. SSH mutual trust configuration steps 1. Each node generates its own public key and private key pair. 2. Send your public key file to the other party. 3. Verify whether the mutual trust configuration is successful. 4. Configure ssh mutual trust here with MYDB01 and

How to connect to Mysql database remotely using Python based on ssh How to connect to Mysql database remotely using Python based on ssh May 27, 2023 pm 04:07 PM

Background: If you need to access the Mysql database of a remote server, but for the security period of the Mysql database, the security measures are set to only allow local connections (that is, you need to log in to the server to use it), and other remote connections cannot be accessed directly, and The corresponding port has also been modified, so you need to connect to the database based on ssh. Connecting to the database in this way is the same as the interface in Navicat based on ssh connection. Navicat connects to the database installation support library. If you want to connect to Mysql, you first need to install pymysqlpipinstallpymysql to install the ssh-based library sshtunnelpipinstallsshtunnel#
