TOMCAT APACHE :

Apache Tomcat is a web server for Java server-side applications. It is a Servlet/JSP container and implements several Java EE specifications.

 

Steps to follow for the installation and configuration of TOMCAT APACHE in RHEL/CentOS:

 

1.  Login as root in server and configure yum local repo if not already configured. (watch below video for yum local repo configuration):

 

 

2. Install tomcat package from repository by yum command.

# yum install tomcat

 

3. Edit tomcat.conf file and append below line there by using vi editor.

# vim /usr/share/tomcat/conf/tomcat.conf

 

JAVA_OPTS="-Djava.security.egd=file:/dev/./urandom -Djava.awt.headless=true -Xmx1026m -XX:MaxPermSize=256m -XX:+UseConcMarkSweepGC"

 

4. Install all other tomcat packages like tomcat webapps, tomcat docs etc.

# yum install tomcat*

 

5. Edit tomcat-user.xml file and write below (use less than symbol before starting this line and greater than symbol after) line there in tomcat-users section by vi editor, save it.

# vim /usr/share/tomcat/conf/tomcat-users.xml

user username="admin" password="password" roles="manager-gui,admin-gui"/

 

6. Start tomcat service now.

# systemctl start tomcat

 

7. Set tomcat service to start automatically after reboot.

# systemctl enable tomcat

 

8. Add port 8080 (to be used by tomcat) in firewall.

# firewall-cmd --permanent --zone=public --add-port=8080/tcp

 

9. Reload the firewall.

# firewall-cmd --reload

 

Now Test your configuration:

Open Firefox and write below line in address bar.

localhost:8080

or

Open any browser and write below line in address bar.

ip-address:8080

(where ip-address is the IP address of your tomcat server)

 

You should see a webpage showing successful configuration of Tomcat Apache.

 

You have successfully installed and configured Tomcat Apache in Linux.
