<p>If the download speed is slow, try to use <aclass="reference external"href="https://maven.aliyun.com/">Ali cloud mirror repository</a>, for example, to download version <codeclass="docutils literal notranslate"><spanclass="pre">3.x.x</span></code> (you can replace <codeclass="docutils literal notranslate"><spanclass="pre">3.x.x</span></code> in the example URL if you want to download other version), the download URL is: https://maven.aliyun.com/repository/public/com/taobao/arthas/arthas-packaging/3.x.x/arthas-packaging-3.x.x-bin.zip</p>
<p>You can install Arthas with one single line command on Linux, Unix, and Mac. Pls. copy the following command and paste it into the command line, then press <em>Enter</em> to run:</p>
<p>The command above will download the bootstrap script <codeclass="docutils literal notranslate"><spanclass="pre">as.sh</span></code> to the current directory. You can move it the any other place you want, or put its location in <codeclass="docutils literal notranslate"><spanclass="pre">$PATH</span></code>.</p>
<p>You can enter its interactive interface by executing <codeclass="docutils literal notranslate"><spanclass="pre">as.sh</span></code>, or execute <codeclass="docutils literal notranslate"><spanclass="pre">as.sh</span><spanclass="pre">-h</span></code> for more help information.</p>
<p>Download and unzip, then find <codeclass="docutils literal notranslate"><spanclass="pre">as.bat</span></code> from ‘bin’ directory. For now this script will only take one argument <codeclass="docutils literal notranslate"><spanclass="pre">pid</span></code>, which means you can only diagnose the local Java process. (Welcome any bat script expert to make it better :heart:)</p>
<p>Let’s suppose we are using <codeclass="docutils literal notranslate"><spanclass="pre">/opt/jdk1.8/bin/java</span></code>, then the command should be:</p>
<li><p><codeclass="docutils literal notranslate"><spanclass="pre">-jar</span><spanclass="pre">/tmp/arthas-packaging/arthas-core.jar</span></code> specifies main entry</p></li>
<li><p><codeclass="docutils literal notranslate"><spanclass="pre">-pid</span><spanclass="pre">15146</span></code> specifies the target java process PID</p></li>
<li><p><codeclass="docutils literal notranslate"><spanclass="pre">-target-ip</span><spanclass="pre">127.0.0.1</span></code> specifies the IP</p></li>
<li><p><codeclass="docutils literal notranslate"><spanclass="pre">-telnet-port</span><spanclass="pre">3658</span><spanclass="pre">-http-port</span><spanclass="pre">8563</span></code> specifies telnet and HTTP ports for remote access</p></li>
<li><p><codeclass="docutils literal notranslate"><spanclass="pre">-core</span><spanclass="pre">/tmp/arthas-packaging/arthas-core.jar</span><spanclass="pre">-agent</span><spanclass="pre">/tmp/arthas-packaging/arthas/arthas-agent.jar</span></code> specifies core/agent jar package</p></li>
<p>If you are running on JDK 1.9 or above，then it’s unnecessary to add <codeclass="docutils literal notranslate"><spanclass="pre">tools.jar</span></code> in option <codeclass="docutils literal notranslate"><spanclass="pre">-Xbootclasspath</span></code>.</p>
<p>You can find the logs from <codeclass="docutils literal notranslate"><spanclass="pre">~/logs/arthas/arthas.log</span></code>.</p>
