ApacheTomcat

一、整合Apache+Tomcat服务器

1. 复制mod_jk_1.2.5_2.0.47.dll文件到C:/Apache2/modules目录。
2. Apache配置:
C:/apahce2/conf/httpd.conf
httpd.conf
在此配置文件最后添加以下语句,用以支持jsp程序:
LoadModule jk_module modules/mod_jk_1.2.5_2.0.47.dll
 
 JkWorkersFile "C:/Tomcat 5.0/conf/workers.properties"
 JkMount /servlet/* ajp13
 JkMount /*.jsp ajp13

3. 查看C:/Tomcat 5.0/conf/server.xml文件中有关端口“8009”是否被注释,如果是和我这的版本一致的话,不用修改。
4. 在C:/Tomcat 5.0/conf/目录下,新建文件名为“workers.properties”的文件,将如下内容复制到新建文件workers.properties中。

workers.properties
# 只复制以下内容即可:

# 这现行根据安装目录做修改
workers.tomcat_home=C:/Tomcat 5.0
workers.java_home=C:/j2sdk1.4.1_01
ps=/
# worker.list=ajp13
worker.list=ajp12,ajp13 

worker.ajp12.port=8007
worker.ajp12.host=localhost
worker.ajp12.type=ajp12
worker.ajp12.lbfactor=1
            
worker.ajp13.port=8009        
worker.ajp13.host=localhost     
worker.ajp13.type=ajp13
worker.ajp13.lbfactor=1

worker.loadbalancer.type=lb

worker.loadbalancer.balanced_workers=ajp12, ajp13
worker.inprocess.type=jni
worker.inprocess.class_path=$(workers.tomcat_home)$(ps)classes
worker.inprocess.class_path=$(workers.tomcat_home)$(ps)lib$(ps)jaxp.jar

worker.inprocess.class_path=$(workers.tomcat_home)$(ps)lib$(ps)parser.jar

worker.inprocess.class_path=$(workers.tomcat_home)$(ps)common$(ps)lib$(ps)jasper.jar

worker.inprocess.class_path=$(workers.tomcat_home)$(ps)common$(ps)lib$(ps)servlet.jar

worker.inprocess.class_path=$(workers.tomcat_home)$(ps)common$(ps)lib$(ps)webserver.jar

worker.inprocess.class_path=$(workers.java_home)$(ps)lib$(ps)tools.jar

worker.inprocess.cmd_line=-config

worker.inprocess.cmd_line=$(workers.tomcat_home)/conf/jni_server.xml

worker.inprocess.cmd_line=-home

worker.inprocess.cmd_line=$(workers.tomcat_home)

worker.inprocess.jvm_lib=$(workers.java_home)$(ps)jre$(ps)bin$(ps)classic$(ps)jvm.dll


worker.inprocess.stdout=$(workers.tomcat_home)$(ps)inprocess.stdout

worker.inprocess.stderr=$(workers.tomcat_home)$(ps)inprocess.stderr

worker.inprocess.sysprops=tomcat.home=$(workers.tomcat_home)


          5. 到此Apache 和 Tomcat整合完成,重启Apache和Tomcat服务器,
用编辑器编写如下内容:



HI-JSP实验


  String Msg = "This is JSP test! 看到这段话,恭喜你,成功了!"; 
  out.print("Hello World!");
%>


The current date and time is


  String str = "Using trim() and substring() can be very useful";
  out.println(str);
%>

保存文件名为“test.jsp”到C:/Tomcat 5.0/webapps/ROOT目录,然后打开浏览器,浏览:http://localhost:8080/test.jsp,如果显示正常,然后将地址改为:http://localhost/test.jsp  显示正常说明配置成功。严格按以上说明安装配置,都会一次成功。

如果想更改tomcat的文档路径,字段中增加

 

二、整合Apache+Tomcat+MySQL
   
      这步相对简单许多,但也是最不容易成功的部分,前面已经将JSP的MySQL驱动放到相应的目录中,环境变量也设置,所以只是测试JSP是否可以连接MySQL数据库。
      1. 测试1,用编辑器编写如下内容:


java.sql.Connection conn;
java.lang.String strConn;
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
conn= java.sql.DriverManager.getConnection("jdbc:mysql://localhost/test","root","");
%>
      注:数据库此处为:test 连接数据库存的用户名为:root  密码为空。根据自己数据库作相应修改。

保存文件名为“test-mysql.jsp”到C:/Tomcat 5.0/webapps/ROOT目录,然后打开浏览器,浏览:http://localhost:8080/test-mysql.jsp 或 http://localhost/test-mysql.jsp ,运行后,如果显示为空白页面,说明连接数据库成功,否则说明没有连接成功,请往回逐步仔细配置。

      2. 测试2,用编辑器编写如下内容:



Connection conn = null;
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
conn = java.sql.DriverManager.getConnection("jdbc:mysql://localhost/test","root","");
if(conn==null){
System.out.println("get Conn Error");
}
Statement stmt=conn.createStatement();
ResultSet RS_result=null;
%>


测试

RS_result=stmt.executeQuery("select * from guestbook");
String Name;
while(RS_result.next())
{
Name=RS_result.getString("name");
%>

}
RS_result.close();
stmt.close();
conn.close();
%>

保存文件名为“test-mysql2.jsp”到C:/Tomcat 5.0/webapps/ROOT目录,然后打开浏览器,浏览:http://localhost:8080/test-mysql2.jsp 或 http://localhost/test-mysql2.jsp

How to configure Dnsmasq as a DHCP relay server How to configure Dnsmasq as a DHCP relay server Mar 21, 2024 am 08:50 AM

The role of a DHCP relay is to forward received DHCP packets to another DHCP server on the network, even if the two servers are on different subnets.
