问题：
centos 5.5 上用 yum 安装了 tomcat， 启动正常，但是访问 8080 端口的网页，是空白的。
查看linux版本
[root@inside ~]# lsb_release -a

查看Tomcat安装目录
先查看使用 yum 安装了那些 名字包含tomcat的软件
[root@inside ~]# rpm -qa|grep tomcat
tomcat5-servlet-2.4-api-5.5.23-0jpp.19.el5_6
tomcat5-jasper-5.5.23-0jpp.19.el5_6
tomcat5-jsp-2.0-api-5.5.23-0jpp.19.el5_6
tomcat5-server-lib-5.5.23-0jpp.19.el5_6
tomcat5-common-lib-5.5.23-0jpp.19.el5_6
tomcat5-5.5.23-0jpp.19.el5_6
查看安装目录
[root@inside ~]# rpm -ql tomcat5
/etc/logrotate.d/tomcat5
/etc/rc.d/init.d/tomcat5
/etc/sysconfig/tomcat5
/etc/tomcat5
/etc/tomcat5/Catalina
/etc/tomcat5/Catalina/localhost
/etc/tomcat5/catalina.policy
从上面可以分析出 tomcat5 的 配置目录 /etc/tomcat5
查看 tomcat 5 的配置：
[root@inside bin]# tomcat5
Found JAVA_HOME: /usr/lib/java
Please complete your /etc/tomcat5/tomcat5.conf so we won’t have to look for it next time
Using CATALINA_BASE: /usr
Using CATALINA_HOME: /usr
Using CATALINA_TMPDIR: /usr/temp
Using JRE_HOME:
Usage: dtomcat5 ( commands … )
commands:
debug Start Catalina in a debugger
debug -security Debug Catalina with a security manager
jpda start Start Catalina under JPDA debugger
run Start Catalina in the current window
run -security Start in the current window with security manager
start Start Catalina in a separate window
start -security Start in a separate window with security manager
stop Stop Catalina
stop -force Stop Catalina (followed by kill -KILL)
version What version of tomcat are you running?

启动 Tomcat
[root@inside ~]# service tomcat5 restart
Stopping tomcat5: [ OK ]
Starting tomcat5: [ OK ]
从上面可以看到，启动正常
检查端口开放状况
netstat –nat
可以看到 8080 端口是处于监听状态的。

分析了好久没找到原因，卸掉重装。
