实验环境：
IP:10.0.0.10
系统：CentOS 6.4
jdk版本：java version "1.8.0_65"
tomcat版本：Apache Tomcat/8.0.24
apache版本：Apache/2.2.27 (Unix)
思路：
1、安装Apache
2、安装tomcat
3、安装mod_jk
4、加载mod_jk
5、关闭tomcat的侦听端口
6、应用分离(静态与动态页面分离)
安装apache

在虚拟主机目录里面分别建两个index.html文件。并启动apache程序，用域名访问两个网站(注：此处需要在本地做hosts解析)如果可以访问，则apache正常运行了(需关闭防火墙和安全策略)
[root@oracle data]# /usr/local/apache2/bin/apachectl -t 测试配置文件是否Ok

[root@oracle data]# /usr/local/apache2/bin/apachectl start 启动apache

apache安装完毕。
安装jk_mod:
# tar -xzf tomcat-connectors-1.2.32-src.tar.gz
# cd tomcat-connectors-1.2.32-src/
# cd native/
# ./configure --with-apxs=/usr/local/apache2/bin/apxs
# make && make install #
ll /usr/local/apache2/modules/mod_jk.so
-rwxr-xr-x 1 root root 1076923 Feb 20 19:14 /usr/local/apache2/modules/mod_jk.so
安装jdk,因为tomcat的运行必须要jdk的支持。
[root@oracle src]# rpm -qa|grep java ---查看是否安装有jdk且版本是否支持
java-1.5.0-gcj-1.5.0.0-29.1.el6.x86_64
gcc-java-4.4.7-3.el6.x86_64

解压tomcat程序：
[root@oracle src]# unzip apache-tomcat-8.0.24.zip
[root@oracle src]# mv apache-tomcat-8.0.24 tomcat1
[root@oracle src]# \cp -r tomcat1 tomcat2

[root@oracle bin]# chmod +x *.sh
[root@oracle src]# cd /usr/local/src/tomcat2/bin
