Apache和Tomcat的集群配置

作者：linvsfen 编辑： ITPUB实习编辑 2006-10-27 00:05

【IT168技术文档】
   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

<!-- Define the top level container in our container hierarchy
<Engine name=”Catalina” defaultHost=”localhost” debug=”0”>
-->

和把下面的注释去掉

<Engine name="Standalone" defaultHost="localhost" jvmRoute="tomcat51">

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）

<VirtualHost *:80>
    ServerAdmin linvsfen◎163.com
    DocumentRoot "d:/ Tomcat51/webapps/jsp-examples
    ServerName localhost
    ErrorLog logs/error_log
    CustomLog logs/access_log common
  </VirtualHost>

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
