This article will help you to install Tomcat 7 on CentOS/RHEL servers. We are using CentOS 6.5 and installing Apache tomcat 7.0.53. To read more about this release read Tomcat Release Notes.

Step 1: Check JAVA

JAVA is the first requirement for Tomcat 7 installation. Make sure you have JAVA SE 6 or Later version installed in your system. Use following command to check if you have java installed already on your system.

# java -version

java version "1.8.0"
Java(TM) SE Runtime Environment (build 1.8.0-b132)
Java HotSpot(TM) Client VM (build 25.0-b70, mixed mode)

If you do not have java installed, Use any article Install Java 7 or Install Java 8 in RHEL based systems.

Step 2: Download and Extract Tomcat Archive

Download Apache Tomcat archive file from Apache tomcat official download page. You can use below wget command to download it.

# cd /opt
# wget http://www.eu.apache.org/dist/tomcat/tomcat-7/v7.0.53/bin/apache-tomcat-7.0.53.tar.gz

After competed download extract archive file in /opt directory. You may change this location as per your requirements.

# tar xzf apache-tomcat-7.0.53.tar.gz
Step 3: Start Tomcat

Tomcat is very easy to use, There are no need to compile its source. You simple extract the archive and start the tomcat server. Tomcat by default start on port 8080, Make sure no other services are running on same port using ‘telnet localhost 8080′.

# cd apache-tomcat-7.0.53
# ./bin/startup.sh

[Sample Output]

Step 5: 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 6: Stop Tomcat

Finally if you feel that there are no need of Tomcat in your system, You can simply stop it using below command from tomcat home directory.

 # ./bin/shutdown.sh
