中间件－－Apache和tomcat的集群配置

我的运行环境:Windows2003 Server SP4 + J2SDK1.5.0 + Apache2.0.54 + Tomcat5.5.9

**准备软件:

1、Apache 2.0.54

2、Tomcat 5.5.14

3、Jk2连接器（mod_jk2.so）

一：软件的部署和配置计划：(修改server.xml)

Configuration Parameter Instance 1 Instance 2 Instance 3

Instance Type Load Balancer Cluster Node 1 Cluster Node 2

Node name AP-LB TC01 TC02

Node IP 192.168.0.12 192.168.0.12 192.168.0.12

Home Directory D:/apache2 D:/tomcat51 D:/tomcat52

Server Ports 8005 9005

AJP Connector Ports 8009 8011

Coyote/JK2 AJP Connector 8080 9080

Cluster mcastAddr 228.0.0.4 228.0.0.4

Cluster mcastPort 45564 45564

tcpListenAddress 192.168.0.12 192.168.0.12

Cluster tcpListenPort 4000 4001

Route Tomcat51 Tomcat52

软件的安装步骤如下：

1、 首先按照JDK1.5.0

2、 安装Apache ，按照完成后启动Apache，使用IE访问http://localhost
测试Apache运行是否正常。

3、 在192.168.0.12上安装tomcat，安装完成后，启动tomcat，使用IE访问http://localhost:8080
，测试tomcat运行是否正常。

4、 编写一个jsp文件（sessiontest.jsp）把testsession.jsp放到webapps/jsp-examplse;，将tomcat51拷贝到的d:/下,修改名字tomcat52；

在tomcat51中的testsession.jsp有提示信息Index Page Served By tocmat51，在tomcat52的testsession.jsp有提示信息Index Page Served By tomcat52

4、在tc01和tc02bin下编辑startup.bat，分别添加

set CATALINA_HOME=D:/tomcat51和set CATALINA_HOME=D:/tomcat52

5、 注释掉tc01和tc02中server.xml的

和把下面的注释去掉

TC02的jvmRoute="tomcat52"

6、 在TC01的jk2.properties添加：

# Sample jk2.properties file for Tomcat5A

channelSocket.address=192.168.0.12

channelSocket.port=8009

shm.file=D:/Apache2/conf/jk2.shm

TC02的channelSocket.port＝8011

7、将mod_jk2.so复制到d:/Apache2/modules目录下：

1.编辑d:/Apache2/conf/httpd.conf文件,在LoadModule那一段代码中添加：

LoadModule jk2_module modules/mod_jk2.so

8、将AddDefaultCharset ISO-8859-1 改为 AddDefaultCharset GB2312 使Apache自动支持中文显示；

9、在“虚拟主机配置代码段”中添加：（此段配置可以根据你的实际情况进行修改）

ServerAdmin linvsfen◎163.com

DocumentRoot "d:/ Tomcat51/webapps/jsp-examples

ServerName localhost

ErrorLog logs/error_log

CustomLog logs/access_log common

10、建立并配置Apache2/conf/ workers2.properties,如下：

# Usually commented out on production environments

[logger.apache2]

file=”D:/Apache2/logs/error.log”

level=ERROR

# Provide the basic config needed

[config]

file=D:/Apache2/conf/workers2.properties

debug=1

# Provide the location of shm file on the Apache web server

[shm]

file=D:/Apache2/conf/jk2.shm

size=1000000

# Tomcat51

[channel.socket:192.168.0.12:8009]

host=192.168.0.12

port=8009

tomcatId=tomcat51

group=balanced

lb_factor=1

route=tomcat51

# Tomcat5A worker

[ajp13:192.168.0.12:8009]

channel=channel.socket:tomcat51

# Tomcat52

[channel.socket:192.168.0.12:8011]

host=192.168.0.12

port=8011

tomcatId=tomcat52

group=balanced

lb_factor=1

route=tomcat52

# Tomcat52 worker

[ajp13:192.168.0.12:8011]

channel=channel.socket:tomcat52

# Load balanced worker

[lb:balanced]

worker=ajp13:192.168.0.12:8009

worker=ajp13:192.168.0.12:8011

timeout=30

attempts=2

recovery=90

stickySession=1

noWorkersMsg=Server Busy please retry after some time.

noWorkerCodeMsg=503

# URI mapping

[uri:/jsp-examples/*]

info=Mappings for the Tomcat context jsp-examples

context=/jsp-examples

group=balanced

# Define a status worker to test the run-time request behavior to the all workers

[status:]

# Status URI mapping

[uri:/jkstatus/*]

group=status

11、启动Apache和同时启动tomcat服务。

二．测试集群功能

1、访问http://localhost/jsp-examples/sessiontest.jsp
, Apache将请求发给TC01，返回结果，页面显示信息tomcat51。URL不变

2、再打开一个IE窗口，访问http://192.168.0.12/jsp-examples/sessiontest.jsp

Apache将请求发给TC02，返回结果。页面有信息：tomcat52，URL不变
