tomcat starts in terminal but not running in browser on ubuntu?

Question

I manually installed tomcat7.

It runs on terminal (tomcat started).

But when I try to run it on browser(localhost:8080), page html appears.

I can't find where is the problem

java version "1.7.0_79" OpenJDK Runtime Environment (IcedTea 2.5.5) (7u79-2.5.5-0ubuntu0.14.04.2) OpenJDK Server VM (build 24.79-b02, mixed mode)

Using CATALINA_BASE: /opt/tomcat/

Using CATALINA_HOME: /opt/tomcat/

Using CATALINA_TMPDIR: /opt/tomcat//temp

Using JRE_HOME: /usr/lib/jvm/java-1.7.0-openjdk-i386

Using CLASSPATH:
/opt/tomcat//bin/bootstrap.jar:/opt/tomcat//bin/tomcat-juli.jar Tomcat started.

Thank you

Solution 1

If any error occur during tomcat startup time then that tomcat error is not shown on ubuntu terminal. So you need to check log file from following location.

{tomcat path}/logs/catalina.{date}.log

{tomcat path} = tomcat install path.
{date} = log of date.

Solution 2

Ok, now this may sound silly, but this problem occurred with me also. After a lot of brainwork, I came to this solution.

just add sudo before ./startup.sh

Start tomcat server by the following command from the Tomcat bin directory as:

$ sudo ./startup.sh

Hope this helps.
