【C#】实现Linux多连接与批量操作

0.背景

由于现在工作需要，我要对很多Linux进行批量的安装docker配置hostname、host等等，所以制作一个批量部署的工具就很有必要的，这次我们用到了SSH.NET

1.在项目中添加SSH.NET

2.简单的调用SSH.NET

private static string host = "xxx.xxx.xxx.xx";
        private static string username = "root";
        private static string password = "pwd";

        // Setup Credentials and Server Information
        public static ConnectionInfo ConnNfo = new ConnectionInfo(host, 22, username,
             new AuthenticationMethod[]{
                // Pasword based Authentication
                new PasswordAuthenticationMethod(username,password),
                 // Key Based Authentication (using keys in OpenSSH Format)
                 //new PrivateKeyAuthenticationMethod("username",new PrivateKeyFile[]{
                 //    new PrivateKeyFile(@"..\openssh.key","passphrase")
                 //}),
             }
         );

        static void Main(string[] args)
        {

            ExecuteCommand1();
            ExecuteCommand2();
            Upload();
            Console.ReadLine();
        }

        /// <summary>
        /// 开始
        /// </summary>
        public void Start()
        {
            using (var client = new SshClient(host, username, password))
            {
                try
                {
                    string command = "ls";
                    client.Connect();
                    string result = client.RunCommand(command).Execute();
                    Console.WriteLine(result);
                    client.Disconnect();
                }
                catch (Exception e1)
                {
                    Console.WriteLine(e1.Message);
                }
            }
        }

        /// <summary>
        /// 执行 command
        /// </summary>
        public static void ExecuteCommand1()
        {
            using (var sshclient = new SshClient(ConnNfo))
            {
                sshclient.Connect();
                using (var cmd = sshclient.CreateCommand("cd /local && ls"))
                {
                    string result = cmd.Execute();
                    Console.WriteLine("Command>" + cmd.CommandText);
                    Console.WriteLine("Return Value = {0}", cmd.ExitStatus);
                    Console.WriteLine("result>" + result);
                }
                sshclient.Disconnect();
            }
        }

        /// <summary>
        /// 执行 command
        /// </summary>
        public static void ExecuteCommand2()
        {
            // Execute (SHELL) Commands
            using (var sshclient = new SshClient(ConnNfo))
            {
                sshclient.Connect();
                // quick way to use ist, but not best practice - SshCommand is not Disposed, ExitStatus not checked...
                Console.WriteLine(sshclient.CreateCommand("cd /local && ls -lah").Execute());
                Console.WriteLine(sshclient.CreateCommand("pwd").Execute());
                Console.WriteLine(sshclient.CreateCommand("cd /local/soft && ls -lah").Execute());
                sshclient.Disconnect();
            }
        }

        /// <summary>
        /// 上传
        /// </summary>
        public static void Upload()
        {
            using (var sftp = new SftpClient(ConnNfo))
            {
                string uploadfn = "Renci.SshNet.dll";

                sftp.Connect();
                sftp.ChangeDirectory("/local/soft");
                using (var uplfileStream = System.IO.File.OpenRead(uploadfn))
                {
                    sftp.UploadFile(uplfileStream, uploadfn, true);
                }
                sftp.Disconnect();
            }
        }

等我做好之后会简单的传一份上来的！
