在Laravel中调用未定义的函数ssh2_connect（）

Question

我尝试在应用程序中运行SSH连接，但出现此错误：

Call to undefined function App\Http\Controllers\Admin\ssh2_connect()

Controller

public function save(Request $request){
        $ip = $request->input('server_ip');
        $sshUser= $request->input('server_ssh_user');
        $sshPw = $request->input('server_ssh_password');

        $sshConnection = ssh2_connect($ip, 22);
        //rest of the code which doesn't execute as result of line above returns error

有什么想法吗？

您需要在服务器上安装以下软件包。

Ubuntu / Debian：

sudo apt-get install php-ssh2
sudo service apache2 restart

Redhat / Centos / Amazon-Linux：

sudo yum install php-ssh2 
sudo service httpd restart (Centos/Redhat/AmazonLinux)
