当服务器性能较差时，或者服务器访问量较大时，就需要tomcat均衡配置以便于分解服务器压力。
有时可能为了安全起见（我们不能保证我门唯一的tomcat能够保持永不宕机）需要备用tomcat来保证服务器在一个tomcat故障时继续正常运行。
当我们要均衡多个tomcat协调运行时就需要一个controller来做为控制调节器，这个controller就是Aphache服务器。
目前拥有两种方式配置tomcat均衡负载现在列举如下:
方式一:
非jk_mod方式，步骤如下:
1）安装apache服务器:
我这里将服务器安装在:
C:
\ProgramFiles（x86）\ApacheSoftwareFoundation\Apache2.2
注意安装时：
在域名输入框（NetworkDomain、SercverName）请输入你的电脑当前ip,邮箱随意输入合法的即可以，选择框默认:
现异常（25032502）请参见附1）
2）拷贝两份解压版tomcat到本地磁盘，我的拷贝到E:
\,并且命名tomcat1、tomcat2
Tomcat无法启动请参见附2）
配置tomcat内存请参照附3）
3）配置两个tomcat的server.xml参数
Tomcat1配置如下（E:
\tomcat1\conf\server.xml）:
xmlversion='1.0'encoding='utf-8'?
