十月份最期待的三件事

在即将到来的十月份，真是很有意义的一个月。

因为有三件事是我最期待的，呵呵

这第一件嘛，自然是我们伟大的祖国60岁的生日，而且到时候会有盛大的阅兵式唷...一定很high，很振奋人心
我记得我上一次看阅兵式的直播还是在1999年--祖国50华诞的时候，那个时候我好像还在上小学，什么都不懂，呵呵
一转眼已经十年过去了，感受颇多呀

这个第二件嘛，就是10月下旬，应该是下旬吧（按照惯例来讲）...就是我最爱的GNU/Linux发行版Ubuntu 9.10的正式发布，
据说里面会加入很多新的特性，我是很期待的。随着 alpha 1、alpha 2 …… alpha 5等等的放出，让我越来越感到它的临近，心里别提多兴奋了.

这最后一件嘛，就是微软的最新操作系统Windows 7 的正式发布，发布日期应该是 10.23号。
虽然据说MSDN 和 TechNet 早就放出来了，不过我这个人还是喜欢等等.不管什么事情，正式一点总不会错.

总之，我准备好了迎接09年的十月了

在centos上用mod_jk桥接apache与tomcat

最近在搞Volit提供的免费VPS,感觉有了自己的一台24x7不关机的服务器就是不一样，心里很是开心，不过现在的虚拟主机、VPS基本上都是LAMP这样的一个状况，LAMP的这个P就是指php 或者Perl,Python.
php这门语言虽然我草草学过，有了那么一点Base,姑且算是一个php starter吧～～
不过我感觉还是java来的更好一点，不管在写法规范，还是程序思想上，还是java舒服点，于是我便萌发了把java环境搭建到远程的centos系统上。

安装Java并不是什么难事，一个命令 yum install java-VERSION-openjdk 即可，这样的好处是环境变量也会自动配置好的，呵呵
然后就是tomcat（当然java的web容器并不止这一个，不过我比较喜欢）,它的二进制程序文件包可以在apache官网下载到。

最后就是如何让apache和tomcat之间开始桥接了，我搜索了一下，用到了apache的一个模块,叫mod_jk.so
关于这个mod_jk，着实让我郁闷了一阵，原来它有两个版本，一个是mod_jk2,一个是mod_jk.
刚开始，从名字上看，我想当然的以为mod_jk2是较新版本。可是我怎么也搜索不到下载地址
后来在apache的Archive镜像里面找到了,一看“最后修改时间”，吓死我了，2004年!!

后来才知道mod_jk2已经停止开发，mod_jk是现行的版本.最新版本是jk-1.2.28。
下载地址：http://www.apache.org/dist/tomcat/tomcat-connectors/jk/binaries/linux/jk-1.2.28/i586/

当然你也可以下载源码进行编译安装,而且呆会用到的workers.properties配置文件的sample也包含在源码包里面。
http://www.apache.org/dist/tomcat/tomcat-connectors/jk/source/jk-1.2.28/tomcat-connectors-1.2.28-src.tar.gz

搞清楚这些事情，接下来就好办了，复制mod_jk.so 到 apache下的modules目录，在httpd.conf里面load一下.
然后复制源码包里面的workers.properties文件到apache下的conf目录，打开，依照里面的说明和注释大概也可以看懂mod_jk的工作原理.

先指定tomcat的路径
workers.tomcat_home=/usr/local/tomcat
再制定jdk的路径
workers.java_home=/usr
然后就是一个worker的列表
创建一个worker,也可以是多个
worker.list=worker1 (,worker2,worker3...)
指定此worker1的类型
worker.worker1.type=ajp13
指定worker1的端口号
worker.worker1.port=8007
worker.worker1.port=8009
指定worker1的服务器路径
worker.worker1.host=localhost

以及下面一系列属性，可以参照
http://tomcat.apache.org/connectors-doc-archive/jk2/jk/workershowto.html#A%20sample%20worker.properties
去配置

worker.worker1.lbfactor=50
worker.worker1.cachesize=10
worker.worker1.cache_timeout=600
worker.worker1.socket_keepalive=1
worker.worker1.socket_timeout=300

配置好后，在apache的配置文件里面通过
JkWorkersFile /etc/httpd/conf/workers.properties 指定其位置

日志路径
JkLogFile /var/log/httpd/mod_jk.log
日志等级
JkLogLevel info
日志时间格式
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
指定增加或去除哪些功能模块
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
记录请求的格式
JkRequestLogFormat "%w %V %T"
指定哪些目录下的文件要通过tomcat转义，编译并指定列表中的哪个worker
JkMount /examples/servlet/* worker1
JkMount /examples/*.jsp worker1

以上这些建议写在VirtualHost节点里面，如果apache下有多个站点的话。
至此，就算是都配置好了，很多配置节点参见：http://tomcat.apache.org/connectors-doc-archive/jk2/jk/aphowto.html
tomcat目录/ sh startup.sh 启动tomcat.
apache目录/ bin/apachectl start 启动apache.
输入 http://localhost/ 看看吧

Oh!  We also plan to kick off our2009 Community Choice Awardsprogram next
week.  In the meantime, start thinking about the projects you want to
nominate!

== March Project of the Month: dotProject ==

dotProject is a Project Management tool written in PHP that aims to be a
best-of-breed project management system. Rather than a generic container
approach like a CMS or groupware app, we decided that we would do a generic
project management tool. We are not industry (or use specific), it's not a
project planning tool - it is designed to serve as an information gathering
and progress reporting tool.
