CloudStack 脚本封装分析
cloud.keystore是这样生成的String dname = "cn=\"" + cn + "\",ou=\"" + ou + "\",o=\"" + o + "\",c=\"" + c + "\"";
Script script = new Script(true, "keytool", 5000, null);
script.add("-genkey");
script.add("-keystore", keystorePath);
script.add("-storepass", "vmops.com");
script.add("-keypass", "vmops.com");
script.add("-keyalg", "RSA");
script.add("-validity", "3650");
script.add("-dname", dname);
String result = script.execute();
if (result != null) {
throw new IOException("Fail to generate certificate!: " + result);
}
