linux下apache和tomcat的整合
1.首先到apache的官方网站下载软件包
httpd-2.2.0.tar.gz
apache-tomcat-5.5.12.tar.gz
jakarta-tomcat-connectors-1.2.15-src.tar.gz

2、安装Apache。
# tar xzvf httpd-2.2.0.tar.gz
# cd httpd-2.2.0
# ./configure --prefix=/usr/local/apache2 --enable-so
# make
# make install
3、安装Tomcat。
# cp apache-tomcat-5.5.12.tar.gz /usr/local/
# cd /usr/local
# tar xzvf apache-tomcat-5.5.12.tar.gz
# ln -s apache-tomcat-5.5.12 tomcat
4、编译生成mod_jk。
# tar xzvf jakarta-tomcat-connectors-1.2.15-src.tar.gz
# cd jakarta-tomcat-connectors-1.2.15-src/jk/native
# ./configure --with-apxs=/usr/local/apache2/bin/apxs
# make
# cp ./apache-2.0/mod_jk.so /usr/local/apache2/modules/
5、配置。
在/usr/local/apache2/conf/下面建立两个配置文件mod_jk.conf和workers.properties。
# vi mod_jk.conf
添加以下内容：
# 指出mod_jk模块工作所需要的工作文件workers.properties的位置
JkWorkersFile /usr/local/apache2/conf/workers.properties
# Where to put jk logs
JkLogFile /usr/local/apache2/logs/mod_jk.log
# Set the jk log level [debug/error/info]
JkLogLevel info
# Select the log format
JkLogStampFormat "[%a %b %d %H:%M:%S %Y]"
# JkOptions indicate to send SSL KEY SIZE,
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
# JkRequestLogFormat set the request format
JkRequestLogFormat "%w %V %T"
# 将所有servlet 和jsp请求通过ajp13的协议送给Tomcat，让Tomcat来处理
JkMount /servlet/* worker1
JkMount /*.jsp worker1
# vi workers.properties
添加以下内容：
# Defining a worker named worker1 and of type ajp13
worker.list=worker1
# Set properties for worker1
worker.worker1.type=ajp13
worker.worker1.host=localhost
worker.worker1.port=8009
worker.worker1.lbfactor=50
worker.worker1.cachesize=10
worker.worker1.cache_timeout=600
worker.worker1.socket_keepalive=1
worker.worker1.socket_timeout=300
再配置httpd.conf，作以下修改：
将Listen 80 修改为 Listen 127.0.0.1:80
将ServerName 修改为 ServerName LocalHost:80
增加关于加载mod_jk的语句：
LoadModule jk_module modules/mod_jk.so
Include /usr/local/apache2/conf/mod_jk.conf
编辑Tomcat的配置文件server.xml，在HOST段中加入：
<Context path="" docBase="/usr/local/apache/htdocs" debug="0" reloadable="true" crossContext="true"/>

启动Apache和Tomcat，用浏览器访问http://localhost/，如果在浏览器中出现It works!则证明配置正确
