is a opensource webserver product of Apache Foundation like Apache HTTP server. It is used to deploying Java Servlet and JSP applications. To deploy any application in Tomcat we can simply create a war file and deploy them. For more details about you can visit apache official site http://tomcat.apache.org/
Step 1: Verify JAVA
First we need to make sure that we have installed java on or system. JAVA is the first requirement of tomcat installation. Use following command to check if you have java installed already on your system. Try to keep java up to date with latest version.
$ java -version
java version "1.8.0_66"
Java(TM) SE Runtime Environment (build 1.8.0_66-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.66-b17, mixed mode)
Step 2: Download Tomcat 7 Archive
After configuring JAVA properly on your system, let’s download Apache tomcat archive file from Apache official site using http://tomcat.apache.org/download-70.cgi
or use the following command to download Tomcat 7.0.65 from Apache server.
$ cd /opt
$ wget http://www.us.apache.org/dist/tomcat/tomcat-7/v7.0.65/bin/apache-tomcat-7.0.65.tar.gz
After competed download extract archive file in /opt directory. You may change this location as per your setup.
$ tar xzf apache-tomcat-7.0.65.tar.gz
$ mv apache-tomcat-7.0.65 tomcat7
Step 3: Setup Environment Variable
Before starting Tomcat, Configure environment variables by adding entry in ~/.bashrc file, So that system environment can set on system bootup with the following command.
$ echo "export CATALINA_HOME=\"/opt/tomcat7\"" >> ~/.bashrc
$ source ~/.bashrc
Step 4: Start Tomcat
After completing all above configuration, Lets use below command to start Tomcat. There are no need to compile its source. Tomcat by default start on port 8080, So make sure no other application using the same port.
$ cd /opt/tomcat7
$ sudo ./bin/startup.sh
Step 5: Access Tomcat
Tomcat server works on port 8080 default. Access tomcat on web browser by connecting your server on port 8080.
Step 6: Setup User Accounts
Finally we need to create user accounts to secure and access admin/manager pages. Edit conf/tomcat-users.xml file in your editor and paste inside <tomcat-users> </tomcat-users> tags.
# user manager can access only manager section.
<role rolename="manager-gui" />
<user username="manager" password="_SECRET_PASSWORD_" roles="manager-gui" />
# user admin can access manager and admin section both.
<role rolename="admin-gui" />
<user username="admin" password="_SECRET_PASSWORD_" roles="manager-gui,admin-gui" />
Step 7: Create Tomcat7 Init Script
Create a init file /etc/init.d/tomcat7 using following content.
### BEGIN INIT INFO
# Provides: tomcat7
# Required-Start: $network
# Required-Stop: $network
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: Start/Stop Tomcat server
### END INIT INFO
case $1 in
restart) stop; start;;
*) echo "Run as $0 "; exit 1;;
Now execute following commands to set proper permissions and symbolic links for init script.
$ chmod 755 /etc/init.d/tomcat7
$ update-rc.d tomcat7 defaults
