java和php异构系统的配置(横向扩展用)(日期:2010-08-25)
1、首先安装并配置好apache和php5,并自己测试成功。
2、apache tomcat 整合
windows 和linux步骤类似,只写linux
首先linux下载java,最好是jdk1.6版本或以上。安装java环境。网上都有介绍。假设linux机器的ip是 192.168.1.2。
然后,下载tomcat6.0,安装tomcat,然后 执行tomcat/bin/startup.sh ,然后随便找台机器进入浏览器,http://192.168.1.2:8080/测试,如果看到猫的页面,就ok。
下面是整合apache和tomcat
第1步:下载jk这个动态连接库,进入http://www.apache.org/dist/tomcat/tomcat- connectors/jk/binaries/
然后进入适当的目录,根据系统和apache的版本下载。
第2步:把下载来的文件mod_jk***.so放到$apache_home/modules下
第3步:打开tomcat/conf/server.xml
找到
在这一行的下面加一行并保存
显然,modJk="D:\Apache2\modules\mod_jk.so"双引号里的内容应该根据操作系统从根目录到 mod_jk***.so的完整路径和文件名。
第4步:然后,linux下
进入tomcat/bin目录分别执行以下命令重启tomcat6
./catalina.sh stop
./catalina.sh start
第5步:正常来说,进入tomcat/conf下会发现多了两个目录,auto和jk目录
这时进入auto目录,打开里面的文件,把里面的内容复制,
进入linux的apache/conf目录,打开httpd.conf
把刚才的内容复制到httpd.conf文件的最后,其实内容就是两个
一个是加载一个模块
一个是指定浏览器访问哪些目录下的文件apche会主动寻找tomcat。
第6步:再加一句
DirectoryIndex index.html index.php index.jsp
注意,如果加这句之前先在httpd.conf文件寻找已经存在的DirectoryIndex指令行并先注释掉,免得冲突
第7步:保存httpd.conf,重启apache,通常要进入apache/bin所在目录,执行
./apachectl stop
./apachectl start
如果启动不起来,说明httpd.conf文件有错误,需要自行调整。
现在,如果浏览器输入
http://192.168.1.2/examples/jsp/jsp2/tagfiles/hello.jsp
会正确显示jsp页面。
注意:只要浏览器输入url时不特别指定端口,则就是访问远程服务器的80端口,所以现在
可以知道页面一定是通过apache转给tomcat的,因为tomcat在没修改配置时只监听8080端口,而不是80端口。
而apache默认只监听80端口。
而tomcat现在也可以监听8080端口并给出反应,
浏览器输入
http://192.168.1.2:8080/examples/jsp/jsp2/tagfiles/hello.jsp
能看到同样结果
而http://192.168.1.2/phpinfo.php
也能访问php程序。
可以用防火墙屏蔽掉linux的8080端口,让tomcat只接收本机的apache的请求转发即可。
当然,更好的做法是只开放80和22端口,别的都禁止,因为tomcat还有别的端口开放。
