关于使用java执行shell脚本获取centos的硬盘序列号和mac地址

1.获取硬盘序列号:

新建shell脚本文件: identifier.sh, 内容为:

diskdata=`fdisk -l`
diskleft=${diskdata#*"identifier: "}
identifier=${diskleft%%" Device Boot"*}
echo ${identifier}

调整identifier.sh的权限:

chmod +x identifier.sh

使用Java代码去调用该shell脚本获取结果

private static String getIdentifier() throws Exception {
    String path = "/usr/local/webapp/identifier.sh";
    Process process = Runtime.getRuntime().exec(path);
    process.waitFor();

    BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));
    StringBuffer sb = new StringBuffer();
    String line;
    while ((line = br.readLine()) != null){
        sb.append(line);
    }
    String str = sb.toString();
    return str;
}

2. 获取MAC地址:

新建shell脚本文件: macAddress.sh, 内容为:

macAddress=`ifconfig | awk -F'[ :]+' '!NF{if(eth!=""&&ip=="")print eth;eth=ip4=""}/^[^ ]/{eth=$1}/inet addr:/{ip=$4}'`
ifconfig ${macAddress[1]} | grep "ether" | awk '{print $2}'

调整macAddress.sh的权限:

chmod +x macAddress.sh

使用Java代码去调用该shell脚本获取结果

private static String getMACAddress() throws Exception {
    String path = "/usr/local/webapp/macAddress.sh";
    Process process = Runtime.getRuntime().exec(path);
    process.waitFor();

    BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));
    StringBuffer sb = new StringBuffer();
    String line;
    while ((line = br.readLine()) != null){
        sb.append(line);
    }
    String str = sb.toString();
    return str;
}

===============================================

测试:

public static void main(String[] args) throws Exception {

    System.out.println("==========kaishi==========");
    String macAddress = getMACAddress();
    System.out.println("macAddress is: " + macAddress);
    
    String identifier = getIdentifier();
    System.out.println("identifier is: " + identifier);
    
    String uniquelyID = macAddress + "_" + identifier;
    System.out.println("uniquelyID is: " + uniquelyID);
    System.out.println("==========jieshu==========");

}

===============================================

输出:

==========kaishi==========
macAddress is: **:**:**:**:**:**
identifier is: *x********
uniquelyID is: **:**:**:**:**:**_*x********
==========jieshu==========

使用java代码执行Linux命令:

1. 执行 "ifconfig" 命令

    private static String getMacAddress() throws Exception {
        String[] cmd = {"ifconfig"};

        Process process = Runtime.getRuntime().exec(cmd);
        process.waitFor();

        BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));
        StringBuffer sb = new StringBuffer();
        String line;
        while ((line = br.readLine()) != null) {
            sb.append(line);
        }

        return str1;
    }

 2. 执行 "fdisk -l" 命令

    private static String getIdentifier() throws Exception {
        String[] cmd = {"fdisk", "-l"};

        Process process = Runtime.getRuntime().exec(cmd);
        process.waitFor();

        BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));
        StringBuffer sb = new StringBuffer();
        String line;
        while ((line = br.readLine()) != null) {
            sb.append(line);
        }

        String str1 = sb.toString();

        return str1;
    }
