1 需求:
apache-tomcat-5.5.27
jdk1.6.0_10
tomcat-connectors-1.2.27
httpd-2.2.10
2 安装:
1) 分别在三台机器上安装 tomcat,路径为/var/apps/apache-tomcat-5.5.27
2) 分别在三台机器上配置JDK,JAVA_PATH=/var/apps/jdk1.6.0_10
3) 在其中一台机器上安装apache,路径为/var/apps/httpd-2.2.10
4) 配置生成mod_jk.so
进入tomcat-connectors-1.2.27/native
执行:./configure --with-apxs=/var/apps/httpd-2.2.10/bin/apxs
make;make install
3 配置apache:
httpd.conf:
LoadModule jk_module modules/mod_jk.so JkWorkersFile conf/workers.properties JkLogFile 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]" # JkRequestLogFormat set the request format JkRequestLogFormat "%w %V %T" # JkOptions indicate to send SSL KEY SIZE, JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories # 将所有servlet 和jsp请求通过ajp13的协议送给Tomcat，让Tomcat来处理 JkMount /servlet/* loadbalancer JkMount /*.jsp loadbalancer
注:也可以把配置文件写在mod_jk.conf 文件中,然后在httpd.conf中,加入include conf/mod_jk.conf
workers.properties:
(自tomcat-connectors-1.2.27/conf中复制到httpd-2.2.10/conf中)

apache服务器的tomcat:不需要做什么修改
tomcat服务器:
ajp12:
<Engine name="Catalina" defaultHost="localhost" jvmRoute="ajp12"> ajp13:
<Engine name="Catalina" defaultHost="localhost" jvmRoute="ajp13">
5 启动服务:
启动tomcat,apache的服务
p.s.
出现错误:org.apache.jk.common.MsgAjp processHeader
严重: BAD packet signature 256
解决方法:workers.properties文件中,tomcat服务器的协议类型错误,应都改为ajp13,即为ajp协议V13.
