CentOS6.5下Tomcat7 Nginx Redis配置步骤教程详解

<p>
所有配置均在一台机器上完成，部署拓扑信息如下：</p>
<p>
<strong><span>注意：由于redis配置对jar包和tomcat版本比较严格，请务必使用tomcat7和本文中提供的jar包。</span></strong></p>
<p>
下载地址：</p>
<p>
http://pan.baidu.com/s/1bo67ky</p>
<p>
tomcat: tomcat1 localhost:8080</p>
<p>
tomcat2 localhost:9080</p>
<p>
nginx: localhost:1210</p>
<p>
redis: localhost:6379</p>
<p>
<span><strong>1. tomcat的安装和配置</strong></span></p>
<p>
1. 在server.xml文件中，修改tomcat2的端口，总共需要修改3处，分别是8080、8005和8009，分别修改为9080、9005和9008。</p>
<p>
配置完此步，在浏览器中输入http://localhost:8080 和 http://localhost:9080便可看到tomcat的首页了。</p>
<p>
<span><strong>2. nginx配置，实现负载均衡。</strong></span></p>
<p>
2.1 安装pcre。因为nginx的rewrite模块需要pcre支持，所以需要安装pcre库。</p>
<p>
2.1.1. 获取pcre编译安装包，在http://www.pcre.org/上可以获取当前最新的版本</p>
<p>
2.1.2. 解压缩pcre-xx.tar.gz包。</p>
<p>
2.1.3. 进入解压缩目录，执行./configure。</p>
<p>
2.1.4. make</p>
<p>
2.1.5. make install</p>
<p>
2.2 安装nginx。由于yum源中没有我们想要的nginx，因此需要创建一个yum源。步骤如下：</p>
<p>
2.2.1. vim /etc/yum.repos.d/nginx.repo</p>
<p>
输入以下内容，然后保存退出。</p>
<div class="jb51code">

<div class="line number5 index4 alt2">
<code class="bash plain">enabled=1</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
2.2.2. 查询一下yum源是否配置好，执行以下命令，若有结果，说明配置成功。</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_795760">
<div class="toolbar">

</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>

<p>
2.2.3. 安装nginx。</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_872095">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>

</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
2.2.4. 配置nginx。实现负载均衡。主要是配置nginx.conf文件，利用 rpm -qc nginx命令查询该配置文件的位置。</p>
<p>

<p>
2.2.5 检查配置文件是否正确，并重启nginx。</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_205034">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">

<div class="line number2 index1 alt1">

<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain">nginx -t</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash plain">service nginx restart 此处也可用如下命令： nginx -s reload</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
2.3 验证负载均衡配置</p>
<p>
2.3.1 分别修改tomcat1和tomcat2首页文件，获取登录的session id值，添加下图中红框的h1标签</p>
<p>
<img style="max-width:100%!important;height:auto!important;"title="CentOS6.5下Tomcat7 Nginx Redis配置步骤教程详解" alt="CentOS6.5下Tomcat7 Nginx Redis配置步骤教程详解" src="https://zhuji.jb51.net/uploads/img/202305/40f87137861e91b1dfd0e41a82a829fb.jpg"></p>
<p>
2.3.2 在浏览器输入： localhost:1210，检查是否配置成功。可以看到，已经跳转到tomcat页面了，配置成功。</p>
