Configure Tomcat Web Management Interface

We already see, how to install tomcat in ubuntu in my previous blog(http://kmlsarwar.blogspot.com/2014/08/how-to-install-apache-tomcat-on-ubuntu.html)

In order to use the manager webapp installed, we must add a login to our Tomcat server. We will do this by editing the tomcat-users.xml file:

sudo nano /etc/tomcat7/tomcat-users.xml 
 
This file is filled with comments which describe how to configure the file. You may want to delete all the comments between the following two lines, or you may leave them if you want to reference the examples:

<tomcat-users> </tomcat-users> 

You will want to add a user who can access the manager-gui and admin-gui (the management interface that we installed in Step Three). You can do so by defining a user similar to the example below. Be sure to change the password and username if you wish:

<tomcat-users>
    <user username="admin" password="password" roles="manager-gui,admin-gui"/>
</tomcat-users>

Save and quit the tomcat-users.xml file. To put our changes into effect, restart the Tomcat service:

sudo service tomcat7 restart
 
Let's take a look at the Web Application Manager, accessible via the link

JavaMelody: Monitoring the Performance of Tomcat Application Server

Javamelody is an opensource (LGPL) application to monitor Java or Java EE application servers in QA and production environments. JavaMelody is mainly based on statistics of requests and on evolution charts. (Extract from the Javamelody home page) It allows to improve applications in QA and production Give facts about the average response times and number of executions Make decisions when trends are bad, before problems become too serious Optimize based on the more limiting response times Find the root causes of response times Verify the real improvement after optimization It includes summary charts showing the evolution over time of the following indicators: Number of executions, mean execution times and percentage of errors of http requests, sql requests, jsp pages or methods of business façades (if EJB3, Spring or Guice) Java memory Java CPU Number of user sessions Number of jdbc connections These charts can be viewed on the current day, week, month, year or cu

Configuring URL Encoding on Tomcat Application Server

Application servers may have different settings for character encodings. We strongly recommend UTF-8 where possible. By default, Tomcat uses ISO-8859-1 character encoding when decoding URLs received from a browser. This can cause problems when Confluence's encoding is UTF-8, and you are using international characters in the names of attachments or pages. To configure the URL encoding in Tomcat: Step 1 - Configure connector: Edit conf/server.xml and find the line where the Coyote HTTP Connector is defined. It will look something like this, possibly with more parameters: < Connector port = "8080" /> Add a URIEncoding="UTF-8" property to the connector: < Connector port = "8080" protocol = "HTTP/1.1"      connectionTimeout = "20000"      redirectPort = "8443"      URIEncoding = "UTF-8" /> If you are using mod_jk you should appl

Set Up Nginx Load Balancing

About Load Balancing Loadbalancing is a useful mechanism to distribute incoming traffic around several capable Virtual Private servers. By apportioning the processing mechanism to several machines, redundancy is provided to the application -- ensuring fault tolerance and heightened stability. The Round Robin algorithm for load balancing sends visitors to one of a set of IPs. At its most basic level Round Robin, which is fairly easy to implement, distributes server load without implementing considering more nuanced factors like server response time and the visitors’ geographic region. Setup The steps in this tutorial require the user to have root privileges on your VPS. Prior to setting up nginx loadbalancing, you should have nginx installed on your VPS. You can install it quickly with apt-get: sudo apt-get install nginx Upstream Module In order to set up a round robin load balancer, we will need to use the nginx upstream module. We will incorporate the conf
