CentOS 6.7系统下安装配置JDK的方法
<p><span><strong>前言</strong></span></p>
<p>
本文是主要是记录CentOS 6.7系统下安装JDK7的过程记录，下面话不多说，来一起看看吧。</p>
<p>
<span><strong>方法如下：</strong></span></p>
<p>
1、上Oracle官方下载最新的JDK安装包，为了方便安装建议下载rpm包</p>
<p>
http://www.oracle.com/technetwork/java/javase/downloads/index.html</p>
<p>
2、在服务器端执行安装</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_723677">
<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">sudo</code> <code class="bash plain">rpm -ivh /目录</code><code class="bash plain">/jdk-7-linux-x64</code><code class="bash plain">.rpm</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
3、设置环境变量</p>
<p>
这里我们需要找到profile文件，添加环境变量：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_104088">
<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 comments">#vim /etc/profile</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
在profile文件下面追加写入下面信息：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_354695">
<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">export</code> <code class="bash plain">JAVA_HOME=</code><code class="bash plain">/usr/java/jdk1</code><code class="bash plain">.7.0</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash functions">export</code> <code class="bash plain">CLASSPATH=.:$JAVA_HOME</code><code class="bash plain">/jre/lib/rt</code><code class="bash plain">.jar:$JAVA_HOME</code><code class="bash plain">/lib/dt</code><code class="bash plain">.jar:$JAVA_HOME</code><code class="bash plain">/lib/tools</code><code class="bash plain">.jar</code>
</div>
<div class="line number3 index2 alt2">
<code class="bash functions">export</code> <code class="bash plain">PATH=$PATH:$JAVA_HOME</code><code class="bash plain">/bin</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
保存退出，执行:</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_259023">
<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 comments">#source /etc/profile</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
