Ubuntu下安装Tomcat

0. 安装文件

http://archive.apache.org/dist/tomcat/tomcat-6/v6.0.28/bin/apache-tomcat-6.0.28.tar.gz 

1. 下载安装文件

under /usr/local/

wget http://archive.apache.org/dist/tomcat/tomcat-6/v6.0.28/bin/apache-tomcat-6.0.28.tar.gz 

2. 解压安装包

tar -zxvf apache-tomcat-6.0.28.tar.gz

3. 配置java环境变量 及tomcat 环境变量

 java 开发环境设置请参考这篇文章 Install Java on Ubuntu server

 添加TOMCAT_HOME 到配置文件 /etc/environment 如下

TOMCAT_HOME=/usr/local/apache-tomcat-6.0.28

4. 启动Tomcat

cd /usr/local/apache-tomcat-6.0.28/bin，
 ./startup.sh
启动tomcat服务器，

若出现：
Using CATALINA_BASE:   /usr/local/apache-tomcat-6.0.28
Using CATALINA_HOME:   /usr/local/apache-tomcat-6.0.28
Using CATALINA_TMPDIR:
/usr/local/apache-tomcat-6.0.28/temp
Using JRE_HOME:       
/usr/lib/sunJVM/JDK/jdk1.6.0_20
Using CLASSPATH:      
/usr/local/apache-tomcat-6.0.28/bin/bootstrap.jar
代码，则基本上正常启动了，输入http://localhost:8080/查看，看看能否出现熟悉的tomcat欢迎界面。 

详细的log信息可以在以下文件夹中找到

/usr/local/apache-tomcat-6.0.28/logs

5、其他配置，可以配置conf/server.xml文件，例如端口号等，
输入命令：sudo gedit
/usr/local/apache-tomcat-6.0.28/conf/server.xml
<Connector port="80"
protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443"
URIEncoding="UTF-8"/>
将监听端口改成80，添加URIEncoding="UTF-8"以支持中文参数传递处理。
停止shutdown服务器命令是：
sudo
./shutdown.sh
