Installing Apache Tomcat as a service on RedHat/CentOS 7

Download Apache tomcat 9.0

wget https://www-us.apache.org/dist/tomcat/tomcat-9/v9.0.19/bin/apache-tomcat-9.0.19.tar.gz

Extract the Tomcat archive and move it to your desired (/opt/tomcat) directory.

tar -zxvf apache-tomcat-*.tar.gz

mv apache-tomcat-*/* /opt/tomcat/

Create tomcat user:

groupadd tomcat

useradd -g tomcat -d /opt/tomcat -s /bin/nologin tomcat

Change the ownership of the directory so that tomcat user can write files in it.

chown -R tomcat:tomcat /opt/tomcat/

TO Start Apache Tomcat Manually use below script:

cd /opt/tomcat/bin/

sh startup.sh

Stop the Apache Tomcat.

cd /opt/tomcat/bin/

sh shutdown.sh

Now If you want to to use systemd for managing Tomcat service.

All the following commands have to be executed with super-user privileges.

Procedure

1. Create the service file with the following command:

touch /etc/systemd/system/tomcat.service

2. Assign the relevant rights to the file you created:

chmod 664 /etc/systemd/system/tomcat.service

NOTE for JRE Path

[aadmin@host1 ~]$ alternatives --list  | grep ^java

java    auto    /usr/java/jdk1.8.0_201-amd64/jre/bin/java

javac   auto    /usr/java/jdk1.8.0_201-amd64/bin/javac

JRE PATH:

/usr/java/jdk1.8.0_201-amd64/jre/

3. Paste the following content in the file while adapting it to your configuration:

[Unit]

[Install]

WantedBy=multi-user.target

4. Reload the service daemon:

systemctl daemon-reload

Enable the auto start of Tomcat service on system start, run:

systemctl enable tomcat

5. Start the service:

systemctl start tomcat.service

[aadmin@host1 ~]$ systemctl status tomcat.service

Verify Apache Tomcat

By default, Tomcat runs on port no 8080. Use netstat command to check whether the service is listening on port 8080 or not.

netstat -antup | grep 8080

tcp6       0      0 :::8080                 :::*                    LISTEN      2428/java

You may need to allow port 8080 in the firewall so that we can access Tomcat from external networks.

firewall-cmd --permanent --add-port=8080/tcp

firewall-cmd --reload

Now open web browser and point to your publicip:8080, you should get the default tomcat page like below:

Web Manager: – Login Required. Username: admin, Password: tomcat
