在Centos上搭建Maven中央仓库的方法

不能说真话的地方 發表於 2023-5-20 00:00:00

<p>
<strong>环境</strong></p>
<p>
<strong>安装java</strong></p>
<p>
在这里使用yum来安装java的jdk，可以使用指令<code>yum search java | grep jdk</code>来查看yum下提供了哪些jdk版本。这里选择1.8版本，安装指令为：<code>sudo yum install java-1.8.0-openjd</code></p>
<p>
安装完毕后还需要修改环境变量，这里的环境变量我们将在<code>/etc/profile.d</code>中添加一个java.sh文件中设置，指令如下：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_592312">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
<div class="line number2 index1 alt1">
2</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash functions">cd</code> <code class="bash plain">/etc/profile</code><code class="bash plain">.d</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash functions">sudo</code> <code class="bash plain">vim java.sh</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
在里面填写如下内容：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterplain" id="highlighter_109152">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
<div class="line number2 index1 alt1">
2</div>
<div class="line number3 index2 alt2">
3</div>
<div class="line number4 index3 alt1">
4</div>
<div class="line number5 index4 alt2">
5</div>
<div class="line number6 index5 alt1">
6</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="plain plain">#set java environment</code>
</div>
<div class="line number2 index1 alt1">
<code class="plain plain">java_home=/usr/lib/jvm/java-1.8.0-openjdk-1.7.0.75.x86_64</code>
</div>
<div class="line number3 index2 alt2">
<code class="plain plain">jre_home=$java_home/jre</code>
</div>
<div class="line number4 index3 alt1">
<code class="plain plain">class_path=.:$java_home/lib/dt.jar:$java_home/lib/tools.jar:$jre_home/lib</code>
</div>
<div class="line number5 index4 alt2">
<code class="plain plain">path=$path:$java_home/bin:$jre_home/bin</code>
</div>
<div class="line number6 index5 alt1">
<code class="plain plain">export java_home jre_home class_path path</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
然后保存并退出。（这里需要了解vim的操作，本文将不详述）</p>
<p>
最后在用<code>source /etc/profile</code>启动环境变量，可以使用<code>java -version</code>查看配置是否成功。</p>
<p>
<strong>安装nexus</strong></p>
<p>
用wget获取nexus的安装包，这里我安装的是2.11.2版本，指令如下：</p>
<p>
</p>
<div class="codetitle">
<span><u>复制代码</u></span> 代码如下:</div>
<div class="codebody" id="code61579">
wget https://sonatype-download.global.ssl.fastly.net/nexus/oss/nexus-2.11.2-03-bundle.tar.gz</div>
<p>
</p>
<p>
然后在当前目录下解压缩并进入文件夹：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_226469">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
<div class="line number2 index1 alt1">
2</div>
<div class="line number3 index2 alt2">
3</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash functions">tar</code> <code class="bash plain">-zxvf nexus-2.11.2-03-bundle.</code><code class="bash functions">tar</code><code class="bash plain">.gz</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash functions">mv</code> <code class="bash plain">nexus-2.11.2-03 nexus </code><code class="bash comments">#重命名文件夹</code>
</div>
<div class="line number3 index2 alt2">
<code class="bash functions">cd</code> <code class="bash plain">nexus</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
<img style="max-width:100%!important;height:auto!important;"title="在Centos上搭建Maven中央仓库的方法" alt="在Centos上搭建Maven中央仓库的方法" src="https://zhuji.jb51.net/uploads/img/202305/9e7417803c624bec9bdcec8306823e43.jpg"></p>
<p>
解压缩后可以看到有两个文件夹，一个是nexus服务，一个是它的私有仓库目录</p>
<p>
然后编辑nexus脚本，它位于<code>nexus_home/bin</code>中，指令如下：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterplain" id="highlighter_562276">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="plain plain">vi bin/nexus</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
将<code>run_as_user</code>改为<code>run_as_user=root</code></p>
<p>
<img style="max-width:100%!important;height:auto!important;"title="在Centos上搭建Maven中央仓库的方法" alt="在Centos上搭建Maven中央仓库的方法" src="https://zhuji.jb51.net/uploads/img/202305/264e6c1921904d2cd25a52d472778d10.jpg"></p>
<p>
这里还需要调整你的防火墙配置，开放恰当的端口，这里就不赘述了。</p>
<p>
然后使用下面指令启动nexus服务：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterplain" id="highlighter_122546">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="plain plain">./bin/nexus start</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
这时就可以在浏览器上访问到nexus服务啦！</p>
<p>
<img style="max-width:100%!important;height:auto!important;"title="在Centos上搭建Maven中央仓库的方法" alt="在Centos上搭建Maven中央仓库的方法" src="https://zhuji.jb51.net/uploads/img/202305/9730c100c15aed60cdc3a7d272deeab9.jpg"></p>
<p>
可以从右上角的log in登录进入系统，默认的角色有三个，我们先用admin的角色进入系统，admin的默认密码为admin123.</p>
<p>
<img style="max-width:100%!important;height:auto!important;"title="在Centos上搭建Maven中央仓库的方法" alt="在Centos上搭建Maven中央仓库的方法" src="https://zhuji.jb51.net/uploads/img/202305/9aad6cd13705b106d9aff5ef676408b1.jpg"></p>
<p>
点击左侧的users查看当前系统的用户。可以看到一共三个用户，admin，deployment和anonymous。</p>
<blockquote>
admin：该用户拥有nexus的全部权限，默认密码为admin123。<br>
deployment：该用户能够访问nexus，浏览仓库内容、搜索、上传部署构件，但是不能对nexus进行任何配置，默认密码为deployment123。<br>
anonymous：该用户对应了所有未登录的匿名用户，它们可以浏览仓库并进行搜索。</blockquote>

<p>
再点击repositories我们可以看到有一下几种默认的类型，我们这里将使用third-party类型的repository，所以我们需要开启其支持编译上传</p>
<p>

<p>
还有很多可以通过ui进行操作，我们这里将不再赘述。下面将介绍如何在本地通过maven将打包好的jar上传到nexus上。</p>
<p>
<strong>maven 打包和部署</strong></p>
<p>
首先我们需要修改本地的maven配置，添加远程仓库的用户名和密码。首先找到本地maven的settings.xml文件。可以使用<code>mvn -version</code>来找到maven的地址：</p>
<p>
<img style="max-width:100%!important;height:auto!important;"title="在Centos上搭建Maven中央仓库的方法" alt="在Centos上搭建Maven中央仓库的方法" src="https://zhuji.jb51.net/uploads/img/202305/e901ca4dfc0034fc459a6442141fa22d.jpg"></p>
<p>
这里可以看到maven home的地址，然后进入这个文件夹config下的<code>settings.xml</code>在里面添加server。这里我们将使用third party那个仓库。</p>
<p>

<p>
然后在需要打包的项目的maven依赖中添加如下内容：</p>

</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
这里的repository_url是指你的仓库的位置，可以在之前展示的repository页面查看到</p>
<p>
maven打包的指令</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterplain" id="highlighter_910164">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="plain plain">mvn clean package</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
此时会在./target目录下看到打包好的jar文件，然后使用如下指令部署：</p>
<p>
</p>
<div class="codetitle">
<span><u>复制代码</u></span> 代码如下:</div>
<div class="codebody" id="code53293">
mvn deploy:deploy-file -dgroupid=com.xy.oracle -dartifactid=ojdbc14 -dversion=10.2.0.4.0 -dpackaging=jar -dfile=./target/xxx.jar -durl=http://ip:8081/nexus/content/repositories/thirdparty/ -drepositoryid=thirdparty</div>
<p>
</p>
<p>
之后就可以在web端看到部署上去的jar包了。</p>
<p>
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持服务器之家。</p>

在Centos上搭建Maven中央仓库的方法
