<p>本教程描述了如何在Ubuntu20.04上安装MongoDB4.4</p><h3 id="安装mongodb">安装MongoDB</h3>
<p>Ubuntu 20.04默认存储库中不提供最新版本的MongoDB，因此需要在系统中添加官方的MongoDB存储库。</p>
<p><strong>首先安装gnupg软件包：</strong></p>
<pre><code class="language-sh">sudo apt-get install gnupg
</code></pre>
<p><strong>导入包管理系统使用的公钥：</strong></p>
<pre><code class="language-sh">wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -
</code></pre>
<p><strong>添加MongoDB存储库：</strong></p>
<pre><code class="language-sh">echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list
</code></pre>
<p><strong>更新存储库：</strong></p>
<pre><code class="language-sh">sudo apt-get update
</code></pre>
<p><strong>使用以下命令安装MongoDB：</strong></p>
<pre><code class="language-sh">sudo apt install mongodb-org
</code></pre>
<p><strong>启动MongoDB服务：</strong></p>
<p>启动MongoDB，同时使用以下命令使其在重新启动时启动</p>
<pre><code class="language-sh">sudo systemctl start mongod.service
sudo systemctl enable mongod
</code></pre>
<p><strong>检查MongoDB服务的状态：</strong></p>
<pre><code class="language-sh">sudo systemctl status mongod
</code></pre>
<p>输出内容如下：</p>
<pre><code class="language-sh">● mongod.service - MongoDB Database Server

</code></pre>
<p><strong>验证安装是否成功完成：</strong></p>
<pre><code class="language-sh">mongo --eval 'db.runCommand({ connectionStatus: 1 })'
</code></pre>
