<p><strong>Latest version, Click To Download</strong>: <a class="reference external" href="http://repository.sonatype.org/service/local/artifact/maven/redirect?r=central-proxy&amp;g=com.taobao.arthas&amp;a=arthas-packaging&amp;e=zip&amp;c=bin&amp;v=LATEST"><img alt="Arthas" src="https://img.shields.io/maven-central/v/com.taobao.arthas/arthas-packaging.svg?style=flat-square" /></a></p>
<p>If the download speed is slow, try to use <a class="reference external" href="https://maven.aliyun.com/">Ali cloud mirror repository</a>, for example, to download version <code class="docutils literal notranslate"><span class="pre">3.x.x</span></code> (you can replace <code class="docutils literal notranslate"><span class="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>
</li>
<li><p>Unzip zip file</p>
<div class="highlight-bash notranslate"><div class="highlight hljs"><pre class="bash">unzip arthas-packaging-bin.zip</pre></div>
</div>
</li>
<li><p>Install Arthas</p>
<p>It is recommended to completely remove all old versions of Arthas before installation.</p>
<div class="highlight-bash notranslate"><div class="highlight hljs"><pre class="bash">sudo su admin
rm -rf /home/admin/.arthas/lib/* # remove all the leftover of the old outdated Arthas
cd arthas
./install-local.sh # switch the user based on the owner of the target Java process.</pre></div>
</div>
</li>
<li><p>Start Arthas</p>
<p>Make sure <code class="docutils literal notranslate"><span class="pre">shutdown</span></code> the old Arthas server before start.</p>
<div class="highlight-bash notranslate"><div class="highlight hljs"><pre class="bash">./as.sh</pre></div>

<div class="section" id="linux-unix-mac">
<h3>Linux/Unix/Mac<a class="headerlink" href="#linux-unix-mac" title="Permalink to this headline"></a></h3>
<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>
<div class="highlight-bash notranslate"><div class="highlight hljs"><pre class="bash">curl -L https://alibaba.github.io/arthas/install.sh | sh</pre></div>
</div>
<p>The command above will download the bootstrap script <code class="docutils literal notranslate"><span class="pre">as.sh</span></code> to the current directory. You can move it the any other place you want, or put its location in <code class="docutils literal notranslate"><span class="pre">$PATH</span></code>.</p>
<p>You can enter its interactive interface by executing <code class="docutils literal notranslate"><span class="pre">as.sh</span></code>, or execute <code class="docutils literal notranslate"><span class="pre">as.sh</span> <span class="pre">-h</span></code> for more help information.</p>

<p>Latest Version, Click To Download: <a class="reference external" href="http://repository.sonatype.org/service/local/artifact/maven/redirect?r=central-proxy&amp;g=com.taobao.arthas&amp;a=arthas-packaging&amp;e=zip&amp;c=bin&amp;v=LATEST"><img alt="Arthas" src="https://img.shields.io/maven-central/v/com.taobao.arthas/arthas-packaging.svg?style=flat-square" /></a></p>
<p>Download and unzip, then find <code class="docutils literal notranslate"><span class="pre">as.bat</span></code> from bin directory. For now this script will only take one argument <code class="docutils literal notranslate"><span class="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>
<div class="highlight-bash notranslate"><div class="highlight hljs"><pre class="bash">as.bat &lt;pid&gt;</pre></div>
</div>
<p>If you want to diagnose Java process run as windows service, try these commands:</p>
<div class="highlight-bash notranslate"><div class="highlight hljs"><pre class="bash">as-service.bat -port &lt;port&gt;
as-service.bat -pid &lt;pid&gt;
as-service.bat -pid &lt;pid&gt; --interact</pre></div>
</div>
<p>Use this command to remove arthas service:</p>
<div class="highlight-bash notranslate"><div class="highlight hljs"><pre class="bash">as-service.bat -remove</pre></div>
</div>
</div>
</div>
<div class="section" id="manual-command-line-startup">
<h2>Manual command line startup<a class="headerlink" href="#manual-command-line-startup" title="Permalink to this headline"></a></h2>
<p>If you fail to boot Arthas with the provided batch file, you could try to assemble the bootstrap command in the following way.</p>
<ol>
<li><p>Locate java in the target JVM:</p>
<ul class="simple">
<li><p>Linux/Unix/Mac: <code class="docutils literal notranslate"><span class="pre">ps</span> <span class="pre">aux</span> <span class="pre">|</span> <span class="pre">grep</span> <span class="pre">java</span></code></p></li>
<li><p>Windows: open the Process Monitor to search java</p></li>
</ul>
</li>
<li><p>Assemble bootstrap command:</p>
<p>Lets suppose we are using <code class="docutils literal notranslate"><span class="pre">/opt/jdk1.8/bin/java</span></code>, then the command should be:</p>
<div class="highlight-bash notranslate"><div class="highlight hljs"><pre class="bash">/opt/jdk1.8/bin/java -Xbootclasspath/a:/opt/jdk1.8/lib/tools.jar \
-jar /tmp/arthas-packaging/arthas-core.jar \
-pid 15146 \
-target-ip 127.0.0.1 -telnet-port 3658 -http-port 8563 \
-core /tmp/arthas-packaging/arthas-core.jar \
-agent /tmp/arthas-packaging/arthas/arthas-agent.jar</pre></div>
</div>
<p>Note:</p>
<ul class="simple">
<li><p><code class="docutils literal notranslate"><span class="pre">-Xbootclasspath</span></code> adds tools.jar</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">-jar</span> <span class="pre">/tmp/arthas-packaging/arthas-core.jar</span></code> specifies main entry</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">-pid</span> <span class="pre">15146</span></code> specifies the target java process PID</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">-target-ip</span> <span class="pre">127.0.0.1</span></code> specifies the IP</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">-telnet-port</span> <span class="pre">3658</span> <span class="pre">-http-port</span> <span class="pre">8563</span></code> specifies telnet and HTTP ports for remote access</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">-core</span> <span class="pre">/tmp/arthas-packaging/arthas-core.jar</span> <span class="pre">-agent</span> <span class="pre">/tmp/arthas-packaging/arthas/arthas-agent.jar</span></code> specifies core/agent jar package</p></li>
</ul>
<p>If you are running on JDK 1.9 or abovethen its unnecessary to add <code class="docutils literal notranslate"><span class="pre">tools.jar</span></code> in option <code class="docutils literal notranslate"><span class="pre">-Xbootclasspath</span></code>.</p>
<p>You can find the logs from <code class="docutils literal notranslate"><span class="pre">~/logs/arthas/arthas.log</span></code>.</p>
</li>
<li><p>Use telnet to connect once attaching to the target JVM (in step 2) succeeds</p>
<div class="highlight-bash notranslate"><div class="highlight hljs"><pre class="bash">telnet 127.0.0.1 3658</pre></div>
