确保你的Debian系统上已经安装了Apache和Tomcat。如果没有安装，可以使用以下命令进行安装：

sudo apt-get update
sudo apt-get install apache2 tomcat9 tomcat9-admin

安装和配置mod_jk

下载并解压mod_jk模块：

wget http://apache.apache.org/dist/tomcat/tomcat-9/v9.0.56/bin/apache-tomcat-9.0.56.tar.gz
tar xzf apache-tomcat-9.0.56.tar.gz
sudo cp -r apache-tomcat-9.0.56/* /usr/share/tomcat9/

编辑Apache的配置文件/etc/apache2/mods-enabled/jk.load，添加以下内容：

LoadModule jk_module /usr/share/tomcat9/lib/apache2/mod_jk.so

创建并编辑/etc/apache2/workers.properties文件：

worker.list=tomcat1,tomcat2
worker.tomcat1.type=ajp13
worker.tomcat1.host=127.0.0.1
worker.tomcat1.port=8009
worker.tomcat1.lbfactor=1
worker.tomcat2.type=ajp13
worker.tomcat2.host=127.0.0.1
worker.tomcat2.port=8011
worker.tomcat2.lbfactor=1

编辑Apache的虚拟主机配置文件，例如/etc/apache2/sites-available/000-default.conf，添加以下内容：

:80>
    ServerName yourdomain.com
    JkMount /* loadbalancer
    JkMount /app1/* loadbalancer
    JkWorkersFile /etc/apache2/workers.properties
    JkShmFile run/jk.shm
    JkLogFile logs/mod_jk.log
    JkLogLevel info
    JkOptions +ForwardKeySize +ForwardURICompatUnparsed -ForwardDirectories
    JkRequestLogFormat "%w %V %T"
    
        Order deny,allow
        Allow from all
    
    ProxyPass /app1 ajp://127.0.0.1:8009/app1
    ProxyPassReverse /app1 ajp://127.0.0.1:8009/app1
