Install Java

Tomcat requires Java to be installed. We can install Open JDK or Oracle Java for development.

Follow below post for Java Installation:
Install Java in Ubuntu Remote Server – Vutr Hosting VPS Example

Check Java version by cmd:

root@gkz-vps:~# java -version
java version "11.0.1" 2018-10-16 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.1+13-LTS)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.1+13-LTS, mixed mode)
Create Tomcat User

We need a new tomcat user for security purposes.

sudo useradd -r -m -U -d /opt/tomcat -s /bin/false tomcat
Install Tomcat

Download the latest binary release of Tomcat 9 from Tomcat Download page:

wget http://www.apache.org/dist/tomcat/tomcat-9/v9.0.13/bin/apache-tomcat-9.0.13.tar.gz -P /tmp

Extract the Tomcat archive & move it to the /opt/tomcat directory:

sudo tar xf /tmp/apache-tomcat-9*.tar.gz -C /opt/tomcat

Create a symbolic link latest which will point to the Tomcat installation directory:

sudo ln -s /opt/tomcat/apache-tomcat-9.0.13 /opt/tomcat/latest

-> For upgrade Tomcat installation, just simply unpack the newer version and change the symlink to point to the latest version.

Change the directory /opt/tomcat/latest ownership to user and group tomcat:

sudo chown -RH tomcat: /opt/tomcat/latest
sudo chmod o+x /opt/tomcat/latest/bin/
Setup Tomcat as a Service

Create a tomcat.service as below:

sudo nano /etc/systemd/system/tomcat.service

Content of tomcat.service as below:

[Unit]
Description=Tomcat 9 servlet container
After=network.target

[Service]
Type=forking

User=tomcat
Group=tomcat

Environment="JAVA_HOME=/usr/local/oracle-java-8/jdk1.8.0_191"
Environment="JAVA_OPTS=-Djava.security.egd=file:///dev/urandom -Djava.awt.headless=true"

Environment="CATALINA_BASE=/opt/tomcat/latest"
Environment="CATALINA_HOME=/opt/tomcat/latest"
Environment="CATALINA_PID=/opt/tomcat/latest/temp/tomcat.pid"
Environment="CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC"

ExecStart=/opt/tomcat/latest/bin/startup.sh
ExecStop=/opt/tomcat/latest/bin/shutdown.sh

[Install]
WantedBy=multi-user.target

Use below cmd to findout JAVA_HOME:

root@gkz-vps:~# echo $JAVA_HOME
/usr/local/oracle-java-11/jdk-11.0.1/bin/java

Save the file and notify systemd for the new tomcat.service changed:

sudo systemctl daemon-reload

Start Tomcat service:

sudo systemctl start tomcat

Check the service status:

sudo systemctl status tomcat

-> Output:

install-java-in-linux-remote-server-with-vultr-hosting-vps-tomcat-status

To be automatically started at boot time, Enable the Tomcat service:

sudo systemctl enable tomcat
Configure Tomcat Web Management

Add new user to tomcat-users.xml to access the Tomcat web interface:

– Open tomcat-users.xml by cmd ->

sudo nano /opt/tomcat/latest/conf/tomcat-users.xml

– Add admin user ->


//
//    Comments
//	  ...
   
   
   

To access the web interface from any IPs address,

-> Manager app, open file: sudo nano /opt/tomcat/latest/webapps/manager/META-INF/context.xml
-> For the Host Manager app, open file: sudo nano /opt/tomcat/latest/webapps/host-manager/META-INF/context.xml

Then change context.xml as below:




We can control specific address IPs for accessing with | operator as below:


  


Now restart Tomcat service to take the effect: sudo systemctl restart tomcat

Check Results
