Installing Java 

Java has two implementations, which are Open JDK and Oracle Java. 

JRE is a subset of JDK and if you already installed the JDK package you do not need to install JRE.

Open JDK 

Install OpenJDK 8 JDK

sudo yum install java-1.8.0-openjdk-devel

Install OpenJDK 8 JRE

sudo yum install java-1.8.0-openjdk

 

Step 5: Downloading Tomcat 7 archive.

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

  • Change your directory to tmp directory.

    cd /tmp

  • Execute the command to download tomcat from the apache servers.

    wget http://www-eu.apache.org/dist/tomcat/tomcat-7/v7.0.90/bin/apache-tomcat-7.0.90.tar.gz

  • Once the download is complete, extract the archive file in /tmp directory and move to a location as per your need. We are placing this under /usr/local directory.

    tar xzf apache-tomcat-7.0.90.tar.gz 
mv apache-tomcat-7.0.90 /usr/local/tomcat7

Step 6: Starting Tomcat.

Tomcat is very easy to use, there is no need to compile its source. You simply extract the archive and start the tomcat server. Tomcat by default starts on port 8080, Make sure no other services are running on same port using ‘telnet localhost 8080'. cd /usr/local/tomcat7
./bin/startup.sh

Step 7: Accessing Tomcat in the browser.

Tomcat server works on port 8080 by default.

Connect to the host server on port 8080. http://yourdomainname.com:8080

Step 8: 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 it inside <tomcat-users> </tomcat-users> tags.

Step 9: Stopping Tomcat.

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

./bin/shutdown.sh
