CENTOS下TOMCAT的安装

1、安装环境                                                       
系统环境：LinuxCentOS5.3操作系统                                                       
服务器软件：Apache Tomcat6                                                       
                    (apache-tomcat-6.0.20.tar.gz)                                   
下载地址为：                                                       
http://tomcat.apache.org/
准备工作：                                                       
拷贝到/usr/local/tomcat6 ---源码目录，其实这个随便你啦！                                                       
tar -zxvf apache-tomcat-6.0.20.tar.gz --解压                                                       
完成编译后，我们就可以启动服务了。。。。。                                                       
cd /usr/local/tomcat6/apache-tomcat-6.0.20/bin                                                       
sh startup.sh --启动服务                                                       
如果没任何错误提示返回的话就证明安装成功了，在浏览器中输入127.0.0.1如果能看到APACHE的预置界面，那就成功了。                                                       
修改tomcat端口为80                                                       
修改/usr/local/tomcat6/apache-tomcat-6.0.20/conf/中的server.xml文件将端口改为80                                                       
开启80端口                                                       
在/etc/sysconfig/iptables中开放80端口                                                       
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT                                                       
开机启动                                                       
在/etc/rc.d/init.d中添加tomcat的启动文件。                                                       
内容见文章最后
文件中要根据系统做现应的改变  
chmod +x tomcat
chkconfig --add tomcat   
chkconfig tomcat on
将tomcat的默认字符编码设置为UTF-8                           
在tomcat目录下conf文件夹下的server.xml中添加
    <Connector port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443"
               URIEncoding="UTF-8" />
在tomcat下的lib文件夹中加入mysql的连接包                       

修改catalina.sh
有时WEB系统比较大要添加tomcat的内存
