<li><p>下载最新版本</p>
<p><strong>最新版本，点击下载</strong>：<a class="reference external" href="http://repository.sonatype.org/service/local/artifact/maven/redirect?r=central-proxy&g=com.taobao.arthas&a=arthas-packaging&e=zip&c=bin&v=LATEST"><img alt="https://img.shields.io/maven-central/v/com.taobao.arthas/arthas-packaging.svg?style=flat-square" src="https://img.shields.io/maven-central/v/com.taobao.arthas/arthas-packaging.svg?style=flat-square" /></a></p>
<p>如果下载速度比较慢，可以尝试用<a class="reference external" href="https://maven.aliyun.com/">阿里云的镜像仓库</a>，比如要下载<code class="docutils literal notranslate"><span class="pre">3.x.x</span></code>版本（替换<code class="docutils literal notranslate"><span class="pre">3.x.x</span></code>为最新版本），下载的url是：</p>
<p>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>解压缩arthas的压缩包</p>
<div class="highlight-default notranslate"><pre class="literal-block">unzip arthas-packaging-bin.zip</pre>
</div>
</li>
<li><p>安装Arthas</p>
<p>安装之前最好把所有老版本的Arthas全都删掉</p>
<div class="highlight-default notranslate"><pre class="literal-block">sudo su admin
rm -rf /home/admin/.arthas/lib/*
cd arthas
./install-local.sh</pre>
</div>
<blockquote>
<div><p>注意，这里根据你需要诊断的Java进程的所属用户进行切换</p>
</div></blockquote>
</li>
<li><p>启动Arthas</p>
<p>启动之前，请确保老版本的Arthas已经<code class="docutils literal notranslate"><span class="pre">stop</span></code>.</p>
<div class="highlight-default notranslate"><pre class="literal-block">./as.sh</pre>
</div>
</li>

<h3>Linux/Unix/Mac<a class="headerlink" href="#linux-unix-mac" title="永久链接至标题">¶</a></h3>
<p>Arthas 支持在 Linux/Unix/Mac 等平台上一键安装，请复制以下内容，并粘贴到命令行中，敲 <code class="docutils literal notranslate"><span class="pre">回车</span></code> 执行即可：</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>上述命令会下载启动脚本文件 <code class="docutils literal notranslate"><span class="pre">as.sh</span></code> 到当前目录，你可以放在任何地方或将其加入到 <code class="docutils literal notranslate"><span class="pre">$PATH</span></code> 中。</p>
<p>直接在shell下面执行<code class="docutils literal notranslate"><span class="pre">./as.sh</span></code>，就会进入交互界面。</p>
<p>也可以执行<code class="docutils literal notranslate"><span class="pre">./as.sh</span> <span class="pre">-h</span></code>来获取更多参数信息。</p>

<div class="section" id="windows">
<h3>Windows<a class="headerlink" href="#windows" title="永久链接至标题">¶</a></h3>
<p>最新版本，点击下载：<a class="reference external" href="http://repository.sonatype.org/service/local/artifact/maven/redirect?r=central-proxy&g=com.taobao.arthas&a=arthas-packaging&e=zip&c=bin&v=LATEST"><img alt="https://img.shields.io/maven-central/v/com.taobao.arthas/arthas-packaging.svg?style=flat-square" src="https://img.shields.io/maven-central/v/com.taobao.arthas/arthas-packaging.svg?style=flat-square" /></a></p>
<p>下载解压后在bin目录有 <code class="docutils literal notranslate"><span class="pre">as.bat</span></code>。此脚本暂时只接受一个参数 pid，即只能诊断本机上的 Java 进程。（欢迎精通bat脚本的开发者改进）</p>
<div class="highlight-default notranslate"><pre class="literal-block">as.bat <pid></pre>
</div>
<p>使用以下命令诊断windows服务模式运行的Java进程 (–interact 打开服务UI交互模式，方便诊断问题)：</p>
<div class="highlight-default notranslate"><pre class="literal-block">as-service.bat -port <port>
as-service.bat -pid <pid>
as-service.bat -pid <pid> --interact</pre>
</div>
<p>清理arthas windows服务执行以下命令：</p>
<div class="highlight-default notranslate"><pre class="literal-block">as-service.bat -remove</pre>
</div>
</div>

<h2>手动拼接命令行启动<a class="headerlink" href="#id2" title="永久链接至标题">¶</a></h2>
<p>如果启动遇到问题，可以尝试手动拼接出命令行参数来启动。</p>
<ol>
<li><p>查找目录jvm的java文件路径。</p>
<p>在linux/mac上执行<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>，在windows上可以通过进程管理器来查看。假设是<code class="docutils literal notranslate"><span class="pre">/opt/jdk1.8/bin/java</span></code>。</p>
</li>
<li><p>拼接出命令行</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>命令行分几部分组成：</p>
<ul class="simple">
<li><p><code class="docutils literal notranslate"><span class="pre">-Xbootclasspath</span></code> 增加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> 指定main函数入口</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">-pid</span> <span class="pre">15146</span></code> 指定目标java进程ID</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">-target-ip</span> <span class="pre">127.0.0.1</span></code> 指定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> 指定telnet和http端口</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> 指定core/agent jar包</p></li>
</ul>
<p>如果是<code class="docutils literal notranslate"><span class="pre">jdk</span> <span class="pre">></span> <span class="pre">9</span></code>，即9/10/11以上的版本，不需要指定<code class="docutils literal notranslate"><span class="pre">tools.jar</span></code>，直接去掉<code class="docutils literal notranslate"><span class="pre">-Xbootclasspath</span></code> 的配置即可。</p>
<p>启动目志输出在<code class="docutils literal notranslate"><span class="pre">~/logs/arthas/arthas.log</span></code>里。</p>
</li>
<li><p>attach成功之后，使用telnet连接</p>
<div class="highlight-bash notranslate"><div class="highlight hljs"><pre class="bash">telnet 127.0.0.1 3658</pre></div>
