Linux学习第二篇 Java环境安装配置教程
<p>本文教程为大家分享了java环境安装配置，供大家参考，具体内容如下</p>
<p>
jdk版本：jdk-8u131-linux-x64.rpm</p>
<p>
注：以下操作在root用户或具有root权限的用户下操作</p>
<p>
<strong>一、将 dk-8u131-linux-x64.rpm拷贝到/home目录下</strong></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_991160">
<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="bash functions">cp</code> <code class="bash plain">jdk-8u131-linux-x64.rpm </code><code class="bash plain">/home/</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
<strong>二、解压rpm文件</strong></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_117856">
<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="bash plain">rpm -ivh jdk-8u131-linux-x64.rpm</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
<strong>三、环境变量的配置</strong></p>
<p>
<span><strong>注：</strong></span>环境变量的配置稍微麻烦一点，不过也不是特别难。</p>
<p>
1.输入以下命令，进入到配置文件中</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_241625">
<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="bash plain">vim </code><code class="bash plain">/etc/profile</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
2.进入配置文件后，这时是不可编辑的状态。要想编辑数据首先输入'i',下方会显示insert单词，这时就可以插入了。在配置文件中加入以下代码即可（记得把路径改为自己的安装路径）。 </p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_978015">
<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>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain">java_home=</code><code class="bash plain">/usr/java/jdk1</code><code class="bash plain">.8.0_131</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash plain">classpath=.:</code><code class="bash plain">/usr/java/jdk1</code><code class="bash plain">.8.0_131</code><code class="bash plain">/jre/lib/rt</code><code class="bash plain">,jar</code>
</div>
<div class="line number3 index2 alt2">
<code class="bash plain">path=$path</code><code class="bash plain">/usr/java/jdk1</code><code class="bash plain">.8.0_131</code>
</div>
<div class="line number4 index3 alt1">
<code class="bash plain">ecport path classpath java_home</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
3.插入过后按‘esc'，此时切换到了不可插入状态，然后在输入':wq'保存并退出。</p>
<p>
4.输入javac查看是否配置成功</p>
