Yum install tomcat on Linux

This tutorial shows how to perform a Tomcat 7 installation using the yum installation utility.
The pre-requisite for installing Tomcat is that you have a JDK on your machine, if you haven't got one, you can install it by executing as root user:
[root@localhost ~]#  yum install java
Next you can start installing Tomcat. There are at least two ways for installing it:

Installation option 1:

Move to http://tomcat.apache.org/ and download the latest stable release of Tomcat. Once done, unzip it to a folder where you have writing permissions:
[tomcat@localhost ~] $ unzip apache-tomcat-7.0.53.zip

Once installed, you can start Tomcat by executing from the TOMCAT_HOME/bin folder:
[tomcat@localhost ~] $ startup.sh

Installation option 2:

You can use the yum utility for installing Tomcat. At the time of writing, just Tomcat 6 is available on the yum repository. You can install it by running:
[root@localhost ~]# yum install tomcat6 tomcat6-webapps tomcat6-admin-webapps

The tomcat6-webapps is not mandatory as it contains some sample applications. The tomcat6-admin-webapps should be installed as it contains the administration application which is deployed as a web application. 
Once installed, you can include it as a service which starts at boot and start it:

[root@localhost ~]#  chkconfig tomcat6 on
[root@localhost ~]#  service tomcat6 start

Checking that Tomcat is running

The simplest way to check that Tomcat is running is by surfing to the address http://localhost:8080 which should show the welcome page:
If you are going to check it by shell, you can use the following methods to check that Tomcat is running:
[tomcat@localhost ~] service tomcat6 status
tomcat6 (pid 4470) is running...                           [  OK  ]

[tomcat@localhost ~] netstat -nlp | grep 8080
tcp        0      0 :::8080                     :::*                        LISTEN      4470/java           

[tomcat@localhost ~] ps -ef | grep tomcat
tomcat   1937     1  1 11:04 ?        00:00:08 /usr/lib/jvm/jre/bin/java
                                                       . . . . . . .

Where has yum installed Tomcat ?

If you have used yum to install Tomcat, the following defaults have been user for Tomcat installation:
Tomcat Service Config: /etc/tomcat6 (main config directory)
Release Notes        : /usr/share/doc/tomcat*
Bin Directory        : /usr/share/tomcat6
Webapps              : /var/lib/tomcat6/webapps
Logs                 : /var/log/tomcat6

Tomcat maxThreads configuration

Tomcat maxThreads represents the maximum number of request
processing threads to be created by the HTTPConnector.

<Connector port="8443" protocol="org.apache.coyote.http11.Http11Protocol" maxThreads="250" SSLEnabled="true" scheme="https" secure="true" clientAuth="false" sslProtocol="TLS" connectiontimeout="20000"/> This determines the maximum number of simultaneous requests that can be handled. If not specified, this attribute is set to the default value of 200.

How the process works:
At server startup, the HTTP Connector will create a number of processing threads based on the value configured for the minSpareThreads attribute. Each incoming request requires a thread for the duration of that request. If the number of simultaneous requests cannot be handled by the currently available request processing threads, additional threads will be created up to the configured maximu…

Tomcat Websocket example

A WebSocket is a full-duplex communication mechanism that allows both textual and binary messages to be sent between clients and servers, without the HTTP request/response life cycle. WebSockets allow either the client or the server to send a message at any time, providing an asynchronous solution for working with data while the user is performing a task.
Websockets API are included in Tomcat 7 Web server distribution so you don't have to download any extra library:

In this tutorial we will show how to create a WebSocket example using Apache Tomcat and Eclipse.
Start by creating on Eclipse a new Dynamic project named websocket-example:
We will now create a server side class named WebSocketDemo that is going to echo messages from a Javascript client:
package com.sample;import java.io.IOException;import java.nio.ByteBuffer;import javax.websocket.OnMessage;import javax.websocket.Session;import javax.websocket.server.ServerEndpoint; @ServerEndpoint("/echo") publicclass WebSoc…

Tomcat Thread Pool configuration

In order to accept incoming requests, Tomcat uses a Thread pool. You can configure two types of Thread Pools: Shared Pool and Dedicated Pool.
A Shared pool as the name inplies, can be shared among various components in Tomcat. So, for example if you have three connectors in your configuration, then you can use a single shared pool to serve requests for all of them. Here is how to configure a shared thread pool:

Open Tomcat's server.xml file and include the Executor definition:

namePrefix="catalina-exec-" maxThreads="150" minSpareThreads="4"/>
Once you have added the shared thread pool, you need to reference it in your Connector configuration as follows:
namePrefix="catalina-exec-" maxThreads="200" minSpareThreads="4"/>
A Dedicated threadpool is a thread pool which is dedicated to only one connector definition. You can use it in a scenario when you are expecting a peak of connections and you want to have ful…
