サーバーにいくつかのプログラムをyumインストールする一連のコマンドを実行するLinuxターミナルでjarファイルを実行できるようにしたいと考えています。目標は、テストのために非常に多くのインストールを行うため、インストール プロセスの一部を自動化することです。次のコードがあります。

public class test 
{
    public static void main(String[] args)
    {
        Runtime rt = Runtime.getRuntime();
        String cmd;

        cmd = "/bin/sh -c yum install -y rpm-build";
        rt.exec(cmd);
    }
}

実行しても何も起こりません。「yum install -y rpm-build」を実行するだけでは問題なく動作しますが、jar を実行して実行するとうまくいきません。私は何を間違っていますか？

JtheRocker のおかげで、ようやく機能するようになりました。他の誰かが同じ問題を抱えている場合の作業コードを次に示します。

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;



public class test 
{
    public static void main(String[] args) throws IOException, InterruptedException
    {
        Runtime rt = Runtime.getRuntime();
        String cmd[] = new String[] {"yum", "install", "-y", "rpm-build"};
        Process ps = rt.exec(cmd);

        BufferedReader readerStd = new BufferedReader(new InputStreamReader(ps.getInputStream()));  

        BufferedReader readerErr = new BufferedReader(new InputStreamReader(ps.getInputStream()));  

        String line = null;  
        while ((line = readerStd.readLine()) != null) {  
            System.out.println(line);  
        }  
        System.out.println("------ Std Err -------");
        while ((line = readerErr.readLine()) != null) {  
            System.out.println(line);  
        }

        if (ps.waitFor()==0) {
            System.out.println("success");
        } else {
            System.out.println("Failed");
        } 
    }
}

これを試して ：

public class test 
{
    public static void main(String[] args)
    {
        Runtime rt = Runtime.getRuntime();
        String cmd[] = new String[] {"yum",  "-y", "install", "rpm-build"};
        Process ps = rt.exec(cmd);

        BufferedReader readerStd = new BufferedReader(new InputStreamReader(ps.getInputStream()));  

        BufferedReader readerErr = new BufferedReader(new InputStreamReader(ps.getInputStream()));  

        String line = null;  
        while ((line = readerStd.readLine()) != null) {  
            System.out.println(line);  
        }  
        System.out.println("------ Std Err -------");
        while ((line = readerErr.readLine()) != null) {  
            System.out.println(line);  
        }

        if (ps.waitFor()==0) {
            System.out.println("success");
        } else {
            System.out.println("Failed");
        } 
    }
}
