I am configuring CentOS 7 system for a Java developer. So firstly I have installed Java using command

wget java-1.7.0-openjdk-

after that installed the downloaded package

yum install java-1.7.0-openjdk-

and it is successfully installed, and I have checked it using

java -version

and below is the command reply

java version "1.7.0_131"
OpenJDK Runtime Environment (rhel- u131-b00)
OpenJDK 64-Bit Server VM (build 24.131-b00, mixed mode)

Please tell me if there is something wrong in the above process. Now I have to install Apache tomcat 8 but I am studying it over net but that is quite confusing because they are creating groups and something like permissions. Please someone tell me the shortest way because we only want to test the system and will deploy a sample test.war for our testing purpose.

after you have installed java on your system, you need to do as i mention here:

#mv apache-tomcat-7 /opt

#useradd tomcat

#chown -R tomcat:tomcat /opt/apache-tomcat-7

To Install tomcat you need to run the startup.sh

#cd /opt/apache-tomcat…


now you make tomcat file in init.d directory to run tomcat as a service.

#vim /etc/init.d/tomcat

  • copy paste the following script in your tomcat file, change directories as it is in your system


# chkconfig: 234 20 80

# description: Tomcat Server basic start/shutdown script

export TOMCAT_HOME=/opt/apache-tomcat-7 START_TOMCAT=${TOMCAT_HOME}/bin/startup.sh STOP_TOMCAT=${TOMCAT_HOME}/bin/shutdown.sh

export downloadPath=/tmp

export JAVA_OPTS="-Xms2g -Xmx2g -XX:PermSize=512m -XX:MaxPermSize=512m"

start() { echo -n "Starting tomcat: " cd ${TOMCAT_HOME}/bin su -p -s /bin/sh tomcat ${START_TOMCAT} echo "done." }

stop() { echo -n "Shutting down tomcat: " cd ${TOMCAT_HOME}/bin su -p -s /bin/sh tomcat ${STOP_TOMCAT} sleep 5 for pid in ps -ef | grep org.apache.catalina.startup.Bootstrap | grep -v grep | awk '{print $2}' | xargs do kill -9 $pid done echo "done." }

case "$1" in




    echo "Usage: $0 {start|stop|restart}"


exit 0

chmod +x /etc/init.d/tomcat

chkconfig --add tomcat

su - tomcat

service tomcat start

note that Permsize, xms and xmx sizes are optional and you need to ask your developers for the exact amount.

if you need help on creating users for the web login on tomcat, please ask.

  • as i mentioned in my answer To Install tomcat you need to run the startup.sh go to your apache directory #cd /opt/apache-tomcat… and run #./bin/startup.sh – Ali Golestan Feb 14 '17 at 7:23

  • if your tomcat service is up and running, use your web browser to open the tomcat server address. check to see if your url is working go to ServerIPaddress:8080 – Ali Golestan Feb 14 '17 at 7:48
