<li>PID：目标 Java 进程 ID（请确保执行当前执行命令的用户必须有足够的权限操作对应的 Java 进程）</li>
<li>IP：Arthas Server 侦听的地址，默认值是 <code class="docutils literal notranslate"><span class="pre">127.00.1</span></code>。Arthas允许多个用户同时访问，并且各自的命令不会相互干扰执行</li>

<p>成熟的线上管理环境一般都不会直接开放 JVM 部署用户权限给你，而是通过 sudo-list 来控制和监控用户的越权操作。由于 as.sh 脚本中会对当前用户的环境变量产生感知，所以需要加上 -H 参数</p>
