详解Linux下Nginx+Tomcat整合的安装与配置
<p><span><strong>一、安装Tomcat和JDK</strong></span></p>
<p>
1、上传apache-tomcat-6.0.18.tar.gz和jdk-6u12-linux-i586.bin至/usr/local</p>
<p>
2、执行如下命令安装tomcat：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_911118">
<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 comments">#cd /usr/local </code>
</div>
<div class="line number2 index1 alt1">
</div>
<div class="line number3 index2 alt2">
<code class="bash comments">#tar zxvf apache-tomcat-6.0.18.tar.gz</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
解压完成后将apache-tomcat-6.0.18重命名为tomcat</p>
<p>
3、执行如下命令安装JDK:</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_59075">
<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">#./jdk-6u12-linux-i586.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>
4、配置环境变量：</p>
<p>
编辑/etc下的profile文件，加上如下内容： </p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterplain" id="highlighter_207524">
<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>
<div class="line number7 index6 alt2">
7</div>
<div class="line number8 index7 alt1">
8</div>
<div class="line number9 index8 alt2">
9</div>
<div class="line number10 index9 alt1">
10</div>
<div class="line number11 index10 alt2">
11</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="plain plain">JAVA_HOME="/usr/local/jdk1.6.0_12"</code>
</div>
<div class="line number2 index1 alt1">
</div>
<div class="line number3 index2 alt2">
<code class="plain plain">CLASS_PATH="$JAVA_HOME/lib:$JAVA_HOME/jre/lib"</code>
</div>
<div class="line number4 index3 alt1">
</div>
<div class="line number5 index4 alt2">
<code class="plain plain">PATH=".:$PATH:$JAVA_HOME/bin "</code>
</div>
<div class="line number6 index5 alt1">
</div>
<div class="line number7 index6 alt2">
<code class="plain spaces"> </code>
</div>
<div class="line number8 index7 alt1">
</div>
<div class="line number9 index8 alt2">
<code class="plain plain">CATALINA_HOME="/usr/local/tomcat"</code>
</div>
<div class="line number10 index9 alt1">
</div>
<div class="line number11 index10 alt2">
<code class="plain plain">export JAVA_HOME CATALINA_HOME</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
5、启动tomcat并输入http://localhost:8080，如果看到猫的页面即tomcat和jdk安装成功</p>
<p>
6、新建文件目录/home/www为网站存放目录，设置server.xml文件，在Host name=”localhost”处将appBase=的指向路径改为/home/www/web</p>
<p>
7、创建index.jsp至/home/www/web/ROOT，内容为：“My web!” </p>
<p>
<span><strong>二、安装Nginx</strong></span></p>
<p>
1、上传nginx-0.7.63.tar.gz至/usr/local</p>
<p>
2、执行如下命令解压nginx：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_104536">
<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 comments">#cd /usr/local </code>
</div>
<div class="line number2 index1 alt1">
</div>
<div class="line number3 index2 alt2">
<code class="bash comments">#tar zxvf nginx-0.7.63.tar.gz</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、编译安装nginx</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_617989">
<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 comments">#cd nginx-0.7.63</code>
</div>
<div class="line number2 index1 alt1">
</div>
<div class="line number3 index2 alt2">
<code class="bash comments">#./configure --with-http_stub_status_module --with-http_ssl_module #启动server状态页和https模块</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
执行完后会提示一个错误，说缺少PCRE library 这个是HTTP Rewrite 模块，也即是url静态化的包</p>
<p>
可上传pcre-7.9.tar.gz，输入如下命令安装：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_177784">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>

</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash comments">#tar zxvf pcre-7.9.tar.gz </code>
</div>
<div class="line number2 index1 alt1">
</div>
<div class="line number3 index2 alt2">
<code class="bash comments">#cd pcre-7.9</code>
</div>
<div class="line number4 index3 alt1">
</div>
<div class="line number5 index4 alt2">

</div>
<div class="line number6 index5 alt1">
</div>
<div class="line number7 index6 alt2">
<code class="bash comments">#make </code>
</div>
<div class="line number8 index7 alt1">
</div>
<div class="line number9 index8 alt2">

</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
安装pcre成功后，继续安装nginx</p>
<div class="jb51code">

<p>
4、nginx安装成功后的安装目录为/usr/local/nginx</p>
<p>
在conf文件夹中新建proxy.conf，用于配置一些代理参数，内容如下：</p>
<div class="jb51code">

5、修改/usr/local/nginx/conf/nginx.conf配置文件后，请执行以下命令检查配置文件是否正确：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_506441">
<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">#/usr/local/nginx/sbin/nginx -t</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
如果屏幕显示以下两行信息，说明配置文件正确： </p>
<p>
the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok</p>
<p>
the configuration file /usr/local/nginx/conf/nginx.conf was tested successfully</p>
<p>
如果提示unknown host，则可在服务器上执行：ping www.baidu.com如果也是同样提示unknown host则有两种可能：</p>
<p>
a、服务器没有设置DNS服务器地址，查看/etc/resolv.conf下是否设置，若无则加上</p>
<p>
b、防火墙拦截</p>
<p>
6、启动nginx的命令</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_783409">
<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">#/usr/local/nginx/sbin/nginx</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
这时，输入以下命令查看Nginx主进程号：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_513666">
<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">ps</code> <code class="bash plain">-ef | </code><code class="bash functions">grep</code> <code class="bash string">"nginx: master process"</code> <code class="bash plain">| </code><code class="bash functions">grep</code> <code class="bash plain">-</code><code class="bash functions">v</code> <code class="bash string">"grep"</code> <code class="bash plain">| </code><code class="bash functions">awk</code> <code class="bash plain">-F </code><code class="bash string">' '</code> <code class="bash string">'{print $2}'</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
7、停止nginx的命令</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_397911">
<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">#/usr/local/nginx/sbin/nginx -s stop</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
8、在不停止Nginx服务的情况下平滑变更Nginx配置</p>
<p>
a、修改/usr/local/nginx/conf/nginx.conf配置文件后，请执行以下命令检查配置文件是否正确：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_640598">
<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">/usr/local/nginx/sbin/nginx</code> <code class="bash plain">-t</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
如果屏幕显示以下两行信息，说明配置文件正确：</p>
<p>
the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok</p>
<p>
the configuration file /usr/local/nginx/conf/nginx.conf was tested successfully</p>
<p>
b、这时，输入以下命令查看Nginx主进程号：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_86087">
<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">ps</code> <code class="bash plain">-ef | </code><code class="bash functions">grep</code> <code class="bash string">"nginx: master process"</code> <code class="bash plain">| </code><code class="bash functions">grep</code> <code class="bash plain">-</code><code class="bash functions">v</code> <code class="bash string">"grep"</code> <code class="bash plain">| </code><code class="bash functions">awk</code> <code class="bash plain">-F </code><code class="bash string">' '</code> <code class="bash string">'{print $2}'</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
屏幕显示的即为Nginx主进程号，例如：</p>
<p>
6302</p>
<p>
这时，执行以下命令即可使修改过的Nginx配置文件生效：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_589295">
<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">kill</code> <code class="bash plain">-HUP 6302</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
或者无需这么麻烦，找到Nginx的Pid文件：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_316930">
<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">kill</code> <code class="bash plain">-HUP `</code><code class="bash functions">cat</code> <code class="bash plain">/usr/local/nginx/nginx</code><code class="bash plain">.pid`</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
9、nginx启动好后启动tomcat，此时输入http://主机ip地址即可看到“My web!”</p>
<p>
<span><strong>三、其他</strong></span></p>
<p>
stub_status</p>
<p>
语法: stub_status on</p>
<p>
默认值: None</p>
<p>
作用域: location</p>
<p>
创建一个 location 区域启用 stub_status</p>
<p>
“stub status” 模块返回的状态信息跟 mathopd's 的状态信息很相似. 返回的状态信息如下：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterplain" id="highlighter_600890">
<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">
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>
<div class="line number7 index6 alt2">
7</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="plain plain">Active connections: 291</code>
</div>
<div class="line number2 index1 alt1">
</div>
<div class="line number3 index2 alt2">

</div>
<div class="line number4 index3 alt1">
</div>
<div class="line number5 index4 alt2">

</div>
<div class="line number6 index5 alt1">
</div>
<div class="line number7 index6 alt2">
<code class="plain plain">Reading: 6 Writing: 179 Waiting: 106</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
active connections — 对后端发起的活动连接数</p>
<p>
server accepts handled requests — nginx 总共处理了 16630948 个连接, 成功创建 16630948 次握手 (证明中间没有失败的), 总共处理了 31070465 个请求 (平均每次握手处理了 1.8个数据请求)</p>
<p>
reading — nginx 读取到客户端的Header信息数</p>
<p>
writing — nginx 返回给客户端的Header信息数</p>
<p>
waiting — 开启 keep-alive 的情况下，这个值等于 active – (reading + writing)，意思就是Nginx说已经处理完正在等候下一次请求指令的驻留连接</p>
<p>
