Installing Apache Tomcat 7 server on Debian

Tomcat es un web server with support servlets and JSPs. Tomcat is not a application server, como JBoss either JONAS. It includes the Jasper compiler, which compiles JSPs into servlets. The Tomcat servlet engine is often presented in combination with the Apache web server.

Tomcat can function as a web server by itself. In the beginning, there was a perception that the use of Tomcat autonomously was only recommended for development environments and environments with minimum requirements for speed and transaction management. Today that perception no longer exists and Tomcat is used as a stand-alone web server in environments with high traffic and high availability.

Since Tomcat was written in Java, works on any operating system that has the java virtual machine.

We install the necessary packages for the operation of Tomcat 

root@srv01:~# apt-get install apache2 mysql-server  openjdk-6-jre

We check that Java has been installed correctly.

root@srv01:~# java -version

java version «1.6.0_18»

OpenJDK Runtime Environment (IcedTea6 1.8.13) (6b18-1.8.13-0+squeeze2)

OpenJDK Client VM (build 14.0-b16, mixed mode, sharing)

We download Tomcat

wget http://apache.rediris.es/tomcat/tomcat-7/v7.0.35/bin/apache-tomcat-7.0.35.tar.gz

We decompress

tar xvzf apache-tomcat-7.0.35.tar.gz

We move the unzipped folder to /usr/local

mv apache-tomcat-7.0.35 /usr/local/

We create a link 

ln -s /usr/local/apache-tomcat-7.0.35 /usr/local/tomcat

To facilitate the management of Tomcat we add the catalina script to the path. 

ln -s /usr/local/tomcat/bin/catalina.sh /usr/local/cantina

we add catalina to the runlevel. 

ln -s /usr/sbin/catalina /etc/rc1.d/K99catalina
ln -s /usr/sbin/catalina /etc/rc2.d/S99catalina

vi /usr/local/tomcat/conf/tomcat-users.xml

<tomcat-users>
<role rolename=»manager»/>

<role rolename=»manager-gui»/>

<role rolename=»admin»/>

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

</tomcat-users>

Using CATALINA_BASE: /usr/local/tomcat

Using CATALINA_HOME: /usr/local/tomcat

Using CATALINA_TMPDIR: /usr/local/tomcat/temp

Using JRE_HOME: /usr

Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar

We access our web server as follows: http://IP_ADDRESS:8080

To access the manager http://IP_ADDRESS:8080/manager/html

It will show us a panel to log in, we have to access it with the credentials created previously in tomcat-users.xml. In our case it is Admin – Tomcat
