apache代理多个tomcat实例

–>

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. 1、安装Apache 

2. 2、安装tomcat 

3. 3、安装mod_jk 

4. 4、加载mod_jk 

5. 5、关闭tomcat的侦听端口 

6. 6、应用分离(静态与动态页面分离) 

安装apache

[[email protected] src]# tar xf httpd-2.2.27.tar.gz 

[[email protected] src]# cd httpd-2.2.27

[[email protected] httpd-2.2.27]# ./configure 

–prefix=/usr/local/apache2       —指定安装路径

–-enable-proxy-balancer           —apache代理balancer模块 

–enable-proxy-http               —apache代理http模块

–enable-proxy-connect            —apache 代理连接模块      

–enable-proxy                    —apache代理模块

–enable-rewrite                   —基本的URL操纵规则，即启用URL重写规则

–enable-proxy-ajp                 —apache代理ajp模块

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)

[[email protected] data]# /usr/local/apache2/bin/apachectl -t     测试配置文件是否Ok

[[email protected] 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。

[[email protected] 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
