Open-JDK-11
Download the archived binary using wget
sudo wget https://builds.openlogic.com/downloadJDK/openlogic-openjdk/11.0.20+8/openlogic-openjdk-11.0.20+8-linux-x64.tar.gz -O /tmp/jdk-11.0.20.tar.gz
Verify the download by listing all files in the /tmp folder
sudo ls /tmp
Create a directory /usr/java
sudo mkdir /usr/java
Extract the open-jdk binary to this now created folder as:
sudo tar -xzvf /tmp/jdk-11.0.20.tar.gz -C /usr/java
Rename the extracted folder to jdk-11.0.20
sudo mv /usr/java/openlogic-openjdk-11.0.20+8-linux-x64 /usr/java/jdk-11.0.20
Now, we need to create environement variable for JAVA_HOME and add java’s bin directory to PATH environment variable. To do so, we can modify the .bashrc file to export these variables whenever a new shell is created
sudo echo -e "export JAVA_HOME=/usr/java/jdk-11.0.20\nexport PATH=$PATH:/usr/java/jdk-11.0.20/bin" >> ~/.bashrc
To make the changes effective in the current session:
source ~/.bashrc
Now check the installation using:
java --version
Apache maven
Download the archived binary using:
Please make sure of the JAVA_HOME path as maven uses jdk to build artifacts
sudo wget https://dlcdn.apache.org/maven/maven-3/3.9.5/binaries/apache-maven-3.9.5-bin.tar.gz -O /tmp/apache-maven-3.9.5.tar.gz
Now extract the downloaded binary file to /opt directory
sudo tar -xzvf /tmp/apache-maven-3.9.5.tar.gz -C /opt
Now, set the M2_HOME and M2 environments variables and update the PATH environment variable as given:
sudo echo -e "export M2_HOME=/opt/apache-maven-3.9.5\nexport M2=/opt/apache-maven-3.9.5/bin\nPATH=$PATH:/opt/apache-maven-3.9.5/bin" >> ~/.bashrc
To make the changes effective:
source ~/.bashrc
To verify the installation:
mvn --version
Tomcat
Create a user called tomcat with primary group name same as user name:
sudo useradd -m -d /opt/tomcat -s /bin/false -U tomcat
Verify user creation using:
sudo cat /etc/passwd | grep tomcat
Download the binary using:
sudo wget -P /tmp https://dlcdn.apache.org/tomcat/tomcat-9/v9.0.80/bin/apache-tomcat-9.0.80.tar.gz
Now, extract the downloaded binary to tomcat user’s home directory:
sudo tar -xvzf /tmp/apache-tomcat-9.0.80.tar.gz -C /opt/tomcat/ --strip-components=1
Check the extraction status:
sudo ls /opt/tomcat/
Now, modify the tomcat directories as below:
Permissions need to be changes for directories such as conf to be owned by root, to prevent deploying applications by any intruders if tomcat user got compromised
sudo chown -R tomcat:tomcat /opt/tomcat
sudo chown -R root /opt/tomcat/conf
sudo chmod 750 /opt/tomcat/conf
sudo find /opt/tomcat/conf -type d -print -exec chmod 750 {} \;
sudo find /opt/tomcat/conf -type f -print -exec chmod 440 {} \;
sudo chown -R root:tomcat /opt/tomcat/lib /opt/tomcat/bin
Please modify the /opt/tomcat/bin/catalina.sh by Replace following line by using vi editor
To open:
sudo vi /opt/tomcat/bin/catalina.sh
On line 226:
CLASSPATH="$CLASSPATH""$CATALINA_HOME"/bin/bootstrap.jar:
With:
CLASSPATH="$CLASSPATH""$CATALINA_HOME"/bin/bootstrap.jar:$CATALINA_HOME/log4j2/lib/*:$CATALINA_HOME/log4j2/conf
To run tomcat as a system service, create a system unit file and append the following content:
sudo vi /etc/systemd/system/tomcat.service
Content to be added:
[Unit]
Description=Apache Tomcat Web Application Container
After=syslog.target network.target

WantedBy=multi-user.target
To introduce the system with newly added service:
sudo systemctl daemon-reload
To enable the tomcat service to be started automatically when the system boots:
sudo systemctl enable tomcat
Start the tomcat server by running:
sudo systemctl start tomcat
Check if tomcat is running:
sudo systemctl status tomcat
MySQL
Download the MySQL setup repository package:
sudo wget https://dev.mysql.com/get/mysql-apt-config_0.8.26-1_all.deb
Run the downloaded deb file to install mysql-server
sudo apt install ./mysql-apt-config_0.8.26-1_all.deb
Follow the screenshots:
select MySQL Server & Cluster from the options given and select ok
Select the server version mysql-8.0 from the optiond given and select
Now, we have configured the repository to be installed, install the mysql server using:
sudo apt install mysql-server -y
Now, setup the mysql server to run right when the system boots up
sudo systemctl enable mysql
Check if mysql server is running
systemctl status mysql
if mysql isn’t running:
sudo systemctl start mysql
ScyllaDB
Install a repo file and add the ScyllaDB APT repository to your system.
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys d0a112e067426ab2
