Centos5下搭建tomcat服务及java应用的部署和管理

Tomcat是Apache 软件基金会(Apache Software Foundation)的Jakarta 项目中的一个核心项目,由Apache、Sun 和其他一些公司及个人共同开发而成。由于有了Sun 的参与和支持,最新的Servlet 和JSP 规范总是能在Tomcat 中得到体现,Tomcat 5 支持最新的Servlet 2.4 和JSP 2.0 规范。因为Tomcat 技术先进、性能稳定,而且免费,因而深受Java 爱好者的喜爱并得到了部分软件开发商的认可,成为目前比较流行的Web 应用服务器。Tomcat 很受广大程序员的喜欢,因为它运行时占用的系统资源小,扩展性好,支持负载平衡与邮件服务等开发应用系统常用的功能;而且它还在不断的改进和完善中,任何一个感兴趣的程序员都可以更改它或在其中加入新的功能。Tomcat 是一个小型的轻量级应用服务器,在中小型系统和并发访问用户不是很多的场合下被普遍使用,是开发和调试JSP 程序的首选。对于一个初学者来说,可以这样认为,当在一台机器上配置好Apache 服务器,可利用它响应对HTML 页面的访问请求。实际上Tomcat 部分是Apache 服务器的扩展,但它是独立运行的。

下面就来介绍下Centos系统如何搭建tomcat服务!
在/usr目录下创建个java目录,并将从sun公司网站上下载下来的JDK包移动到此目录
[root@centos5 ~]# mkdir -p /usr/java
[root@centos5 ~]# mv jdk-6u13-linux-i586.bin /usr/java/
[root@centos5 ~]# cd /usr/java/
[root@centos5 java]# ll
total 78336
-rwxr--r-- 1 yang yang 80129716 May 21 2009 jdk-6u13-linux-i586.bin

安装JDK,并设置下环境变量
[root@centos5 java]#./jdk-6u13-linux-i586.bin

Please enter "yes" or "no".
Do you agree to the above license terms? [yes or no]
yes 此处输入yes

[root@centos5 java]# ls
jdk1.6.0_13 jdk-6u13-linux-i586.bin
[root@centos5 java]# cd jdk1.6.0_13/
[root@centos5 jdk1.6.0_13]# ls

[root@centos5 jdk1.6.0_13]# ./bin/java -version 查看下java的版本信息
java version "1.6.0_13"
Java(TM) SE Runtime Environment (build 1.6.0_13-b03)
Java HotSpot(TM) Client VM (build 11.3-b02, mixed mode, sharing)

[root@centos5 /]# tail -3 /etc/profile 设置java环境变量如下
export JAVA_HOME=/usr/java/jdk1.6.0_13
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin

[root@centos5 /]# source /etc/profile 使环境变量生效
[root@centos5 /]# java -version
java version "1.6.0_13"
Java(TM) SE Runtime Environment (build 1.6.0_13-b03)
Java HotSpot(TM) Client VM (build 11.3-b02, mixed mode, sharing)

从apache网站上下载tomcat包,并移动到/usr/local目录下
[root@centos5 yang]# mv ./apache-tomcat-6.0.18.tar.gz /usr/local/
[root@centos5 yang]# cd /usr/local/
[root@centos5 local]# ls
