<h1> 一、安装jdk、Tomcat、Apache </h1> 1.安装jdk和Tomcat，去官网下载解压简单配置就可运行Tomcat。 2.安装Apache，去官网下载最新的Apache源码包。安装时要指定apr，所以如果操作系统没有安装请下载安装apr、apr-util和pcre。   tar -zxvf httpd-*   ./configure --prefix=/work/installed/apache --with-apr=/work/installed/apr --with-apr-util=/work/installed/apr-util --with-pcre=/work/installed/pcre   make   make install   修改conf/httpd.conf，ServerName localhost:80 <h1> 二、安装jk </h1>    下载jk http://tomcat.apache.org/download-connectors.cgi   解压   cd tomcat-connectors-1.2.40-src/native/   ./configure --with-apxs=/usr/local/apache2/bin/apxs  --with-java-home=/usr/jdk1.7   make   make install <h1> 三、配置集群 </h1>  1.配置jk_module模块，vim conf/httpd.conf增加如下内容   LoadModule jk_module modules/mod_jk.so   <IfModule jk_module>   JkWorkersFile conf/workers.properties   JkMount /* controller   JkLogFile logs/mod_jk.log   JkLogLevel warn   </IfModule>   将LoadModule rewrite_module modules/mod_rewrite.so前面#去掉。  2.在conf目录下vim workers.properties加入如下内容： <ol class="dp-j" style="border:1px solid

#sticky_session=false不使用粘性session,同时配置不复制session时,注意转发请求后可能会找不到原来的session.   </li> </ol>  3.修改每个tomcat的conf/server.xml   <Engine name="Catalina" defaultHost="localhost" jvmRoute="Tomcat1">   <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>   4.修改web应用里面WEB-INF目录下的web.xml文件，加入标签   <distributable/>   直接加在</web-app>之前就可以了   做tomcat集群必须需要这一步，否则用户的session就无法正常使用。 java企业级通用权限安全框架源码
