Apache HttpServer與Tomcat7叢集Linux版

Apache HttpServer與Tomcat的整合見上篇：

http://blog.csdn.net/supercrsky/article/details/8295023

 

一.配置Tomcat

這裡用兩個tomcat，直接在已安裝目錄再複製一個，命名為tomcat2。

#cp -r /opt/tomcat/ tomcat2

進入tomcat2目錄，編輯 conf/server.xml，修改預設連接埠。

#vi conf/server.xml

1.  將

<Server port="8005" shutdown="SHUTDOWN">

改成

<Server port="9005" shutdown="SHUTDOWN">

2.將

<Connector port="8080" protocol="HTTP/1.1"               connectionTimeout="20000"               redirectPort="8443" /> 

修改成：

<Connector port="9090" protocol="HTTP/1.1"               connectionTimeout="20000"               redirectPort="9443" /> 

3. 找到：

<Engine name="Catalina" defaultHost="localhost">

改成

<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat1">

同時把tomcat2中此處內容改成

<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat2">

4.找到

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

改成

<Connector port="9009" protocol="AJP/1.3" redirectPort="8443" />

5.找到

<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster" />

把注釋取消掉。

二．配置HTTP Server

1.檢查是否啟動了https，確保下面這句已經被注釋。

#Include conf/extra/httpd-ssl.conf

2.找到我們在最檔案最下面添加的VirtualHost節點，將其更改為： 

<VirtualHost *>DocumentRoot /usr/local/www/<Directory "/usr/local/www/composite">    AllowOverride None    Order allow,deny    Allow from all</Directory><Directory "/usr/local/www/composite/WEB-INF">         Order deny,allow         Deny from all</Directory>ServerAdmin localhostDocumentRoot /usr/local/www/ServerName localhostDirectoryIndex index.html index.htm index.jsp index.actionErrorLog logs/shsc-error_log.txtCustomLog logs/shsc-access_log.txt commonJkMount /*WEB-INF controllerJkMount /*j_spring_security_check controllerJkMount /*.action controllerJkMount /servlet/* controllerJkMount /*.jsp controllerJkMount /*.do controller</VirtualHost>

4. 編輯conf/workers.properties將內容修改為：

worker.list = controller#tomcat1worker.tomcat1.port=8009       worker.tomcat1.host=localhostworker.tomcat1.type=ajp13worker.tomcat1.lbfactor=1#tomcat2worker.tomcat2.port=9009     worker.tomcat2.host=localhostworker.tomcat2.type=ajp13worker.tomcat2.lbfactor=1#========controller========worker.controller.type=lbworker.controller.balance_workers=tomcat1,tomcat2worker.lbcontroller.sticky_session=0worker.controller.sticky_session_force=trueworker.connection_pool_size=3000worker.connection_pool_minsize=50worker.connection_pool_timeout=50000

這句非常重要worker.list = controller，如果不加httpd會無法啟動，查看日誌報錯：

Could not find a worker for worker name=controller

如果是橫向叢集，將worker.tomcat1.host或worker.tomcat2.host更改為對應的機器IP即可。

 

三．部署並測試

 確保項目裡的WEB-INF/web.xml檔案，在</web-app>之前加入了

 <distributable/>

 將工程分別部署到/usr/local/www，/opt/tomcat/webapps，/opt/tomcat2/webapps

 

 分別啟動tomcat1和tomcat2，順序無所謂，最後啟動HTTP Server

#/opt/tomcat/bin/startup.sh

#/opt/tomcat2/bin/startup.sh

#/usr/local/httpd2.2/bin/apachectl start

啟兩個Firefox，分別訪問我們的工程，這裡是:http://localhost/composite

觀察/opt/tomcat/logs/與/opt/tomcat2/logs/下對應的日誌，

 

我們發現tomcat1和tomcat2已經分別處理了一個用戶端請求。
