【分享&讨论】Apache2 + Tomcat5 配置多站点服务器

[lizhenyang]

假如，现在有3个站点：www.ab26.com，w1.ab26.com，w2.ab26.com，均指向同一服务器（假如公网IP：11.22.333.444）。
下载mod_jk模块，并将其拷贝至Apache安装目录的modules目录下。

Apache配置：

1.修改配置文件httpd.conf，在文件尾加入下面两行：
Include conf/extra/mod_jk.conf
Include conf/extra/thosts.conf

2.在conf目录下新建文件夹extra，所有新建的配置文件都放在这里，以便管理。

3.在extra目录下新建文本文件thosts.conf，内容如下：

# www.ab26.com
<VirtualHost 11.22.333.444:80>
    ServerAdmin [e-mail]
    ServerName ab26.com
    ServerAlias ab26.com www.ab26.com
    DocumentRoot "D:/websites/www.ab26.com/ROOT"
    Alias /mydl/ "D:/dl/"
    <Directory "D:/websites/www.ab26.com/ROOT">
      Options FollowSymLinks
      AllowOverride None
      Order allow,deny
      Allow from all
    </Directory>
    <Location ~"/WEB-INF/">
      AllowOverride None
      deny from all
    </Location>
    <Directory "D:/dl">
      Options Indexes FollowSymLinks
      AllowOverride None
      Order allow,deny
      Allow from all
    </Directory>
    CustomLog "logs/www.ab26.com-access_2009.log" combined
    ErrorLog "logs/www.ab26.com-error_2009.log"
    JkLogFile "logs/www.ab26.com-jk-error_2009.log"
    JkLogLevel error
    DirectoryIndex default.htm index.htm default.jsp index.jsp
    JkMountFile conf/extra/www.ab26.com.properties
</VirtualHost>
# w1.ab26.com
<VirtualHost 11.22.333.444:80>
    ServerAdmin [e-mail]
    ServerName w1.ab26.com
    ServerAlias w1.ab26.com
    DocumentRoot "D:/websites/w1.ab26.com/ROOT"
    <Directory "D:/websites/w1.ab26.com/ROOT">
      Options FollowSymLinks
      AllowOverride None
      Order allow,deny
      Allow from all
    </Directory>
    <Location ~"/WEB-INF/">
      AllowOverride None
      deny from all
    </Location>
    CustomLog "logs/w1.ab26.com-access_2009.log" combined
    ErrorLog "logs/w1.ab26.com-error_2009.log"
    JkLogFile "logs/w1.ab26.com-jk-error_2009.log"
    JkLogLevel error
    DirectoryIndex default.htm index.htm default.jsp index.jsp
    JkMountFile conf/extra/w1.ab26.com.properties
</VirtualHost>
# w2.ab26.com
<VirtualHost 11.22.333.444:80>
    ServerAdmin [e-mail]
    ServerName w2.ab26.com
    ServerAlias w2.ab26.com
    DocumentRoot "D:/websites/w2.ab26.com/ROOT"
    <Directory "D:/websites/w2.ab26.com/ROOT">
      Options FollowSymLinks
      AllowOverride None
      Order allow,deny
      Allow from all
    </Directory>
    <Location ~"/WEB-INF/">
      AllowOverride None
      deny from all
    </Location>
    CustomLog "logs/w2.ab26.com-access_2009.log" combined
    ErrorLog "logs/w2.ab26.com-error_2009.log"
    JkLogFile "logs/w2.ab26.com-jk-error_2009.log"
    JkLogLevel error
    DirectoryIndex default.htm index.htm default.jsp index.jsp
    JkMountFile conf/extra/w2.ab26.com.properties
</VirtualHost>

4.在extra目录下新建文本文件mod_jk.conf，内容如下：
LoadModule jk_module modules/mod_jk.so
JkWorkersFile conf/extra/workers.properties
JkLogFile logs/mod_jk.log
JkLogLevel error

5.在extra目录下新建文本文件workers.properties，内容如下：
workers.tomcat_home=C:\myServer\Tomcat-5.5
workers.java_home=C:\myServer\Java\jre6
worker.list=ajp13_a0,ajp13_a1,ajp13_a2
worker.ajp13_a0.port=8009
worker.ajp13_a0.host=127.0.0.1
worker.ajp13_a0.type=ajp13
worker.ajp13_a1.port=8109
worker.ajp13_a1.host=127.0.0.1
worker.ajp13_a1.type=ajp13
worker.ajp13_a2.port=8209
worker.ajp13_a2.host=127.0.0.1
worker.ajp13_a2.type=ajp13

6.在extra目录下新建文本文件www.ab26.com.properties，内容如下：
/*.jsp=ajp13_a0
/*.do=ajp13_a0
/fckeditor/*=ajp13_a0
!/*.gif=ajp13_a0
!/*.jpg=ajp13_a0
!/*.png=ajp13_a0
!/*.css=ajp13_a0
!/*.js=ajp13_a0
!/*.htm=ajp13_a0
!/*.html=ajp13_a0

7.在extra目录下新建文本文件w1.ab26.com.properties，内容如下：
/*.jsp=ajp13_a1
/*.do=ajp13_a1
/fckeditor/*=ajp13_a1
!/*.gif=ajp13_a1
!/*.jpg=ajp13_a1
!/*.png=ajp13_a1
!/*.css=ajp13_a1
!/*.js=ajp13_a1
!/*.htm=ajp13_a1
!/*.html=ajp13_a1

8.在extra目录下新建文本文件w2.ab26.com.properties，内容如下：
/*.jsp=ajp13_a2
/*.do=ajp13_a2
/fckeditor/*=ajp13_a2
!/*.gif=ajp13_a2
!/*.jpg=ajp13_a2
!/*.png=ajp13_a2
!/*.css=ajp13_a2
!/*.js=ajp13_a2
!/*.htm=ajp13_a2
!/*.html=ajp13_a2

Tomcat配置：

1.修改配置文件server.xml，找到『<Connector port="8009" connectionTimeout="10000" .... protocol="AJP/1.3" />』，在其后添加以下内容：

<Connector port="8109" connectionTimeout="10000" enableLookups="false" redirectPort="8443" protocol="AJP/1.3" />
<Connector port="8209" connectionTimeout="10000" enableLookups="false" redirectPort="8443" protocol="AJP/1.3" />

说明：这一步的配置，我不知道是不是正确。

服务器上的网站现在可以正常浏览，但是也遇到点问题，我通过网站后台（使用了struts2框架）上传图片时，经常会出现图片上传失败的情况（也有上传成功的时候），我在本地测试时一切正常（本地使用Eclipse3+JDK6+Tomcat5开发环境）。不知道是网站程序有问题，还是网站服务器配置的问题。下面附上我上传图片的代码及Struts2的配置。

请高手帮忙指点一下，问题如能解决，不胜感激！

web.xml中struts2的配置：

<filter>
	<filter-name>struts2</filter-name>
	<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
	<init-param>
		<param-name>config</param-name>
		<param-value>struts-default.xml,struts-www.xml</param-value>
	</init-param>
</filter>
<filter-mapping>
	<filter-name>struts2</filter-name>
	<url-pattern>*.do</url-pattern>
</filter-mapping>
<filter-mapping>
	<filter-name>struts2</filter-name>
	<url-pattern>*.jsp</url-pattern>
</filter-mapping>

struts-www.xml文件相关内容：

<constant name="struts.locale" value="zh_CN" />
<constant name="struts.i18n.reload" value="true" />
<constant name="struts.i18n.encoding" value="UTF-8" />
<constant name="struts.action.extension" value="do" />
<constant name="struts.ui.theme" value="simple" />
<constant name="struts.multipart.maxSize" value="5000000" />
<package name="udFile" extends="struts-default">
	<action name="doUpfile" class="com.httpUtils.Upfile" method="upload">
		<interceptor-ref name="defaultStack">
			<param name ="allowedTypes">image/bmp,image/png,image/gif,image/jpeg</param>
			<param name="maximumSize">5000000</param>
		</interceptor-ref>
		<result name="input">selectFile.jsp</result>
		<result name="success">previewFile.jsp</result>
	</action>
</package>

Upfile.java内容如下：

package com.httpUtils;
import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;

public class Upfile {
	private static final long serialVersionUID = 1L;
	private File myFile;
	private String fileName;
	private String contentType;
	private String filePath;

	public String upload(){
		filePath = "upfiles/";
		String yName = StringUtil.getDateTime(1);
		String mdName = StringUtil.getDateTime(6);
		String feName = StringUtil.getDateTime(9) + getFileExt();//获取当前时间，用来重命名上传的文件
		RrscAction.createFolder(filePath);//创建不存的文件夹
		filePath += yName +"/";
		RrscAction.createFolder(filePath);
		filePath += mdName +"/";
		RrscAction.createFolder(filePath);
		filePath += feName;
		String realPath = RrscAction.getRealPath(filePath);
		save2file(myFile,realPath);
		return "success";
	}
	private String getFileExt(){
		int pos = getFileName().lastIndexOf(".");//出错时，会提示getFileName()为null
		if(-1<pos)
			return getFileName().substring(pos);
		else
			return ".noExt";
	}
	private void save2file(File src,String nfp){
		final int BUFFER_SIZE = 1024;
		try{
			File nf = new File(nfp);
			InputStream in = null;
			OutputStream out = null;
			try{
				in = new BufferedInputStream(new FileInputStream(src),BUFFER_SIZE);
				out = new BufferedOutputStream(new FileOutputStream(nf),BUFFER_SIZE);
				byte[] buffer = new byte[BUFFER_SIZE];
				while(0<in.read(buffer))
					out.write(buffer);
			} finally {
				if(null!=in)
					in.close();
				if(null!=out)
					out.close();
			}
		} catch (Exception e){
			e.printStackTrace();
		}
	}
	public void setMyFile(File myFile){
		this.myFile = myFile;
	}
	public void setMyFileFileName(String fileName) {
		this.fileName = fileName;
	}
	public void setMyFileContentType(String fileType) {
		this.contentType = fileType;
	}
	public void setFilePath(String filePath) {
		this.filePath = filePath;
	}
	public File getMyFile(){
		return myFile;
	}
	public String getFileName() {
		return fileName;
	}
	public String getMyFileContentType() {
		return contentType;
	}
	public String getFilePath() {
		return filePath;
	}
}

selectFile.jsp主要内容：

<s:form action="doUpfile" method="post" name="upFileForm" onsubmit="return check(this);" enctype="multipart/form-data">
	<input name="myFile" type="file">
	<input type="submit" name="Submit" value="上传" >
</s:form>

更正：Apache配置，第5步中，workers.properties文件中最后一行：worker.ajp13_ss.type=status，这一行没有。
