How to install Tomcat 7 on RHEL7/Centos7

Step 1: Java installation: Installation step you can find here.

Step 2: Installation Tomcat 7: Download tar file from Apache tomcat official site. 

Step 3: Copy that downloaded file in /opt/ and Extract here as shown below:

[root@linuxcnf ~]# cd /opt/ [root@linuxcnf opt]# ls apache-tomcat-7.0.86.tar.gz  [root@linuxcnf opt]# tar zxvf apache-tomcat-7.0.86.tar.gz  [root@linuxcnf opt]# mv apache-tomcat-7.0.86 /usr/local/tomcat7

Step 4: Set environment variables

[root@linuxcnf ~]# vi /etc/profile # add following lines into the end of the file export CATALINA_HOME/usr/local/tomcat7 export PATH=/usr/local/tomcat7/bin:$PATH :wq [root@linuxcnf ~]# source /etc/profile

Step 5: Verify environment variables setting:

[root@linuxcnf ~]# echo $CATALINA_HOME /usr/local/tomcat7

Step 6: Add user for tomcat authentication:

[root@linuxcnf ~]# vi $CATALINA_HOME/conf/tomcat-users.xml #Add this below lines in the file after --> and before this line "</tomcat-users>" in tomcat users section. <role rolename="manager-gui"/>   <role rolename="manager-status"/>   <role rolename="manager-script"/>   <role rolename="manager-jmx"/>   <role rolename="admin"/> <user username="username" password="password" roles="manager-gui,manager-                         script,manager-status,manager-jmx,admin"/> :wq

Step 7: Create a service scrip to auto start the server after reboot:

[root@linuxcnf ~]# vi /etc/rc.d/init.d/tomcat #!/bin/bash # Tomcat: Start/Stop Tomcat

. /etc/init.d/functions . /etc/sysconfig/network CATALINA_HOME=/usr/local/tomcat7 LOCKFILE=/var/lock/subsys/tomcat7 RETVAL=0 start(){     echo "Starting Tomcat7: " $CATALINA_HOME/bin/startup.sh     RETVAL=$?     echo     [ $RETVAL -eq 0 ] && touch $LOCKFILE     return $RETVAL } stop(){     echo "Shutting down Tomcat7: "     $CATALINA_HOME/bin/shutdown.sh     RETVAL=$? echo     [ $RETVAL -eq 0 ] && rm -f $LOCKFILE     return $RETVAL } case "$1" in     start)         start         ;;     stop)         stop         ;;     restart)         stop         start         ;;     *)         echo $"Usage: $0 {start|stop|restart}"         exit 1         ;; esac exit $? :wq  [root@linuxcnf ~]# chmod 755 /etc/rc.d/init.d/tomcat [root@linuxcnf ~]# /etc/rc.d/init.d/tomcat start  Starting Tomcat7:                                                        [ok]  [root@linuxcnf ~]# chkconfig tomcat on

  

Step 8: Configure firewall to access tomcat service

[root@linuxcnf ~]# firewall-cmd –permanent --add-port=8080/tcp [root@linuxcnf ~]# firewall-cmd --reload

Tomcat 7 installation and configuration done. For verification start a Web browser and put server ip or host name and port no. e.g. localhost:8080.
