java和php异构系统的配置
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。

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
