Playing with Apache TomCat

-

Apache Tomcat, often referred to simply as Tomcat, should not be confused with the Apache web server. While they are frequently used together, they are separate entities. Apache Tomcat is an open-source servlet container developed by the Apache Software Foundation, implementing the Java Servlet and JSP specifications to provide a "pure Java" HTTP web server environment for Java applications.

Installing Apache Tomcat on Linux

First, download the latest stable version of the JDK. For this guide, we will use JDK 7.

Installing Java SE Development Kit 7

Download JDK 7:

[root@centos garbage]# wget http://download.oracle.com/otn-pub/java/jdk/7/jdk-7-linux-i586.rpm

Install JDK 7:

[root@centos garbage]# rpm -ivh jdk-7-linux-i586.rpm

Verify the installation:

[root@centos garbage]# java
[root@centos garbage]# java -version
java version "1.7.0"
Java(TM) SE Runtime Environment (build 1.7.0-b147)
Java HotSpot(TM) Client VM (build 21.0-b17, mixed mode, sharing)

Downloading & Installing Tomcat

The latest stable release at the time of writing is Tomcat 7.0.21.

Download Tomcat:

[root@centos garbage]# wget http://www.apache.org/dist/tomcat/tomcat-7/v7.0.21/bin/apache-tomcat-7.0.21.tar.gz

Extract Tomcat:

[root@centos garbage]# tar vxzf apache-tomcat-7.0.21.tar.gz
[root@centos garbage]# cd apache-tomcat-7.0.21

Using Tomcat

[root@centos apache-tomcat-7.0.21]# cd bin

Starting Tomcat:

[root@centos bin]# ./startup.sh

Stopping Tomcat:

[root@centos bin]# ./shutdown.sh

Now, point your web browser to:

http://yoursitename:8080

You should see the Tomcat Administration page.

To add or remove users, navigate to the "conf" directory within the Apache Tomcat directory and edit the necessary user configurations by adding or modifying the following line as needed:

<user name="desired_Username" password="desired_passwd" roles="admin,manager,tomcat"/>

Server should be SSL-aware but has no certificate configured [Hint: SSLCertificateFile] ((null):0)

-
The error usually arises from one of the following issues: Missing Certificate File: The certificate file may not be located at the specified path. Ensure that the file exists and the path is correctly referenced in your SSL configuration. Incorrect SSL Configuration: There may be issues within your SSL settings. Double-check your configuration files for any errors or misconfigurations that could affect SSL functionality. If neither of these issues seems to be the problem, try the following: Update the Apache Ports Configuration: Open the /etc/apache2/ports.conf file and locate the line that reads "Listen 443". Change it to "Listen 443 http". This adjustment can help ensure that Apache correctly listens for secure connections on port 443. By addressing these points, you should be able to resolve the error effectively.

Generating a Self-Signed Certificate for Apache2 SSL Generating a Self-Signed Certificate for Apache2 SSL This guide will help you create a self-signed certificate to enable SSL for Apache2. While using a commercial certificate is preferable for production environments, a self-signed certificate is suitable for development or testing purposes. Step 1: Enable SSL for Apache First, enable the SSL module in Apache: sudo a2enmod ssl Step 2: Create a Directory for Certificates Next, create a directory to store your self-signed certificate and its associated keys: sudo mkdir /etc/apache2/certificate Step 3: Generate the Self-Signed Certificate Now, generate the keys for your self-signed certificate. You will be prompted to provide some information during this process: sudo openssl req -new -x509 -days 1095 -nodes -out /etc/apache2/certificate/apache.pem -keyout /etc/apache2/certificate/apache.key During this step, you will see output similar to this:...

-
In Standard Solaris, IPS is exclusively a feature of Oracle Solaris 11. While Oracle Solaris 10 provides some tools to achieve similar functionality, their use in production environments raises questions about reliability. Historically, package installation in Solaris has been challenging. Fortunately, some solutions now provide IPS-like functionality: 1. OpenCSW To utilize IPS functionality with OpenCSW in Oracle Solaris 10, follow these steps: Download the package from: http://mirror.opencsw.org/opencsw/current/i386/5.10/pkgutil-2.4%2CREV%3D2011.05.15-SunOS5.8-i386-CSW.pkg.gz Unzip the downloaded package: gunzip pkgutil-2.4,REV=2011.05.15-SunOS5.8-i386-CSW.pkg.gz Install the package: pkgadd -d pkgutil-2.4,REV=2011.05.15-SunOS5.8-i386-CSW.pkg Fetch the latest catalog: pkgutil --catalog Install any package with all dependencies: pkgutil -i vim 2.
