Apache与tomcat的整合、负载均衡和加入启动和系统服务.docx

资源描述

Apache与tomcat的整合及负载均衡系统环境：Windows Server 2008 R2 SP1 虚拟机软件：Hyper-V管理器 6.1.7601.17514 虚拟机环境：Red Hat Enterprise Linux Server release 5.4 (Tikanga) X64 安装软件版本：JDK:1.6.0_19 Tomcat:6.0.20 Apache:2.2.19 JK: 1.2.10 实施步骤：一、安装软件。。。 1 tar -xzvf jdk1.6.0_19.tar.gz 2 tar xvfz tomcat.tar.gz 3 tar zxvf httpd-2.2.19.tar.gz 4 cd httpd-2.2.19 5 ./configure --prefix=/usr/local/apache2 --enable-so --enable-mods-shared=most --with-mpm=worker 6 make 7 make install 8 tar zxvf jakarta-tomcat-connectors-1.2.10-src.tar.gz 9 cd jakarta-tomcat-connectors-1.2.10-src/jk/native/ 10 ./buildconf.sh 11 ./configure --with-apxs=/usr/local/apache2/bin/apxs 12 make 13 make install 二、配置整合及负载均衡 1 cp /usr/local/jakarta-tomcat-connectors-1.2.10-src/jk/native/apache-2.0/mod_jk.so /usr/local/apache2/modules 2 配置环境变量 vi /etc/profile 在文本末尾加入以下内容 JAVA_HOME=JDK安装路径 CATALINA_HOME=tomcat安装路径 CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$CATALINA_HOME/lib/servlet-api.jar PATH=$JAVA_HOME/bin:$PATH export JAVA_HOME CATALINA_HOME CLASSPATH PATH 3 应用初始的环境变量 source /etc/profile 4 修改apache的httpd.conf vi /usr/local/apache2/conf/httpd.conf 修改以下几处并且在末尾加上：Include /usr/local/apache2/conf/mod_jk.conf 5 添加及设置mod_jk.conf vi /usr/local/apache2/mod_jk.conf 增加以下内容 #加载mod_jk Module LoadModule jk_module modules/mod_jk.so #指定 workers.properties文件路径 JkWorkersFile conf/workers.properties JkLogFile logs/mod_jk.log JkLogLevel info #指定那些请求交给tomcat处理,"controller"为在workers.propertise里指定的负载分配控制制器 JkMount /* lb 6 添加及设置workers.properties vi /usr/local/apache2/conf/workers.properties 添加以下内容 worker.list = lb,tomcat1,tomcat2 #server 列表 #========tomcat1======== worker.tomcat1.port=8009 #ajp13 端口号，在tomcat下server.xml配置,默认8009 worker.tomcat1.host=10.1.1.2 #tomcat的主机地址，如不为本机，请填写ip地址 worker.tomcat1.type=ajp13 worker.tomcat1.lbfactor = 1 #server的加权比重，值越高，分得的请求越多 #========tomcat2======== worker.tomcat2.port=8009 #ajp13 端口号，在tomcat下server.xml配置,默认8009 worker.tomcat2.host=10.1.1.3 #tomcat的主机地址，如不为本机，请填写ip地址 worker.tomcat2.type=ajp13 worker.tomcat2.lbfactor = 1 #server的加权比重，值越高，分得的请求越多 #========controller,负载均衡控制器======== worker.lb.type=lb worker.lb.balanced_workers=tomcat1,tomcat2 #指定分担请求的tomcat worker.lb.sticky_session=1 7、将JSP文件放入/usr/local/tomcat/webapps/ROOT 8 启动apache和tomcat 8 打开浏览器输入 http://apache服务器的地址或者localhost/index.jsp 就是这么简单。三、将apache和tomcat加入启动和系统服务选项 1 Apache加入启动项里面： echo '/usr/local/apache2/bin/apachectl start ' >> /etc/rc.local 2 Apache加入到系统服务里面: cp /安装目录下/apache/bin/apachectl /etc/rc.d/init.d/httpd 修改httpd 在文件头部加入如下内容： ### # Comments to support chkconfig on RedHat Linux # chkconfig: 2345 90 90 # description:http server ### 保存在打入 chkconfig --add httpd chkconfig --level 345 httpd on 3 tomcat加入启动和系统服务选项安装jsvc #cd /usr/local/tomcat/bin #tar xvfz jsvc.tar.gz #cd jsvc-src #sh support/buildconf.sh #chmod 755 configure #./configure --with-java=/usr/local/java (改成你的JDK的位置) #make 注：我在執行./configure --with-java=/usr/local/java 的過程中，產生"configure: error:no acceptable C compiler found in $PATH "這樣的錯誤提示，發現是沒有安裝C編譯器，于是執行“yum install gcc”安裝了gcc,之后重新執行./configure --with-java=/usr/local/java 就Ok了修改启动文件 #vi ./native/Tomcat5.sh 改成如下内容: #!/bin/sh # chkconfig: 345 87 13 # description: Tomcat Daemon # processname: jsvc # pidfile: /var/run/jsvc.pid # config: # Source function library. # . /etc/rc.d/init.d/functions # prog=tomcat # Small shell script to show how to start/stop Tomcat using jsvc # If you want to have Tomcat running on port 80 please modify the server.xml # file: # port="80" minProcessors="5" maxProcessors="75" # enableLookups="true" redirectPort="8443" # acceptCount="10" debug="0" connectionTimeout="60000"/> # You need a developement version of Tomcat (Apache Tomcat/4.1-dev) # Adapt the following lines to your configuration ############################################################################## # # Copyright 2004 The Apache Software Foundation. # # Licensed under the Apache License, Version 2.0 (the "License");
