<p>
couchdb是一个开源的，面向文档的nosql数据库。在本文中，您将学习如何在centos 8上安装apache couchdb。</p>
<h3>
什么是apache couchdb？</h3>
<p>
couchdb是由apache software foundation开发的开源数据库管理系统。它是在erlang中开发的nosql文档存储数据库。</p>
<p>
couchdb使用多种格式和协议来存储，传输和处理其数据，它使用json（javascript对象表示法）存储数据，使用mapreduce将javascript作为查询语言以及api的http。</p>
<p>
与关系数据库不同，couchdb数据库不在表中存储数据和关系。相反，每个数据库都是独立文档的集合。每个文档都维护自己的数据和独立的架构。</p>
<p>
couchdb软件包括一个本地web界面，即用于管理couchdb数据库服务器的fauxton。</p>
<ul>
<li>
cpu：3.4 ghz（2核）</li>
<li>
内存：2 gb</li>
<li>
储存空间：20 gb</li>
<li>
作业系统：centos 8.2</li>
<li>
主机名：couchdb.lianglab.cn</li>
<li>
ip地址：192.168.6.200/24</li>
</ul>
<h3>
第一步：更新centos 8软件包</h3>
<p>
通过使用ssh客户端，以root用户身份与couchdb.lianglab.cn连接。</p>
<p>
最佳做法是在centos 8操作系统上安装任何新东西之前，先更新已安装的软件包。</p>
<p>
使用dnf命令更新centos 8中已安装的软件包。</p>

<h3>
第三步：centos 8上安装couchdb yum存储库</h3>
<p>
可以通过源或rpm软件包将couchdb数据库安装在centos 8上。基于rpm的安装非常简单明了，因此我们从rpm软件包中安装couchdb。</p>
<p>
couchdb数据库rpm软件包通过它们自己的正式yum存储库分发。因此，我们在centos 8操作系统中添加了couchdb yum存储库。</p>

第五步：访问couchdb web ui</p>
<p>
【1】成功启动couchdb服务后，我们现在可以通过在web浏览器中打开url http://192.168.6.200:5984/_utils/来访问fauxton web界面。</p>
<p>

<p>
【2】couchdb登录页面,您可以使用管理员用户（我们已经在local.ini文件中添加了该用户）登录fauxton。</p>

<p>
【3】登录后，安装程序将要求您将couchdb配置为单节点实例或设置集群。单击“配置为单节点”。</p>

<p>
【4】提供管理员用户凭据，绑定ip地址和服务端口。点击“配置节点”。</p>

<p>
【5】在couchdb安装结束时，它将要求您配置复制。忽略它，然后单击左侧边栏上的“数据库”按钮。</p>
<p>

<p>
您现在位于数据库页面。您可以从此页面创建所需的数据库。</p>
<p>
在这里，您可以看到在couchdb安装过程中创建的两个系统数据库以及我们为测试目的而创建的两个用户数据库。</p>
<p>
除了fauxton web界面之外，我们还可以使用curl命令将http命令发送到couchdb实例。</p>
<p>
【6】创建一个couchdb数据库，我们可以使用以下命令。</p>

结论：</p>
<p>
我们已经成功地安装了apache couchdb 3.3的在centos 8理解基础知识和couchdb 的数据库的架构，我们建议你应该购买和阅读couchdb: the definitive guide: time to relax由o'reilly media公司。</p>
