Prepare Required Files

Use an SSH client like MobaXterm to connect to the remote Linux server and transfer the necessary packages: JDK, Apache Tomcat, MySQL, and optionally Nginx. Once uploaded, extract all archives in advance to streamline setup.

# Extract JDK
tar -zxvf jdk-8u151-linux-x64.tar.gz

# Extract Tomcat
tar -zxvf apache-tomcat-8.5.20.tar.gz

# Extract MySQL RPM bundle (preferably into its own directory)
tar -xvf mysql-5.7.35-1.el7.x86_64.rpm-bundle.tar

Install and Configure JDK

Edit the global profile to set environment variables:

sudo vi /etc/profile

Append the following lines (adjust the path to match your extracted JDK location):

# Java environment
export JAVA_HOME=/opt/jdk1.8.0_151
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib
export PATH=$JAVA_HOME/bin:$PATH

Reload the profile and verify the installation:

source /etc/profile
java -version

Configure Tomcat for Auto-Start

Copy Tomcat’s startup script to the system’s init directory and rename it:

cp /opt/apache-tomcat-8.5.20/bin/catalina.sh /etc/init.d/tomcat

Edit /etc/init.d/tomcat and insert the following just after the initial comments:

# chkconfig: 2345 80 20
# description: Tomcat Server

JAVA_HOME=/opt/jdk1.8.0_151
CATALINA_HOME=/opt/apache-tomcat-8.5.20

Make the script executable and register it with the system:

chmod +x /etc/init.d/tomcat
chkconfig --add tomcat
chkconfig tomcat on

Open port 8080 in the firewall if needed:

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

Install and Enable MySQL

First, remove any existing MariaDB packages:

rpm -qa | grep mariadb
sudo rpm -e --nodeps <mariadb-package-name>

Install the required MySQL RPMs from the extracted bundle:

cd mysql-extracted-dir
sudo rpm -ivh mysql-community-common-5.7.35-1.el7.x86_64.rpm
sudo rpm -ivh mysql-community-libs-5.7.35-1.el7.x86_64.rpm
sudo rpm -ivh mysql-community-client-5.7.35-1.el7.x86_64.rpm
sudo rpm -ivh mysql-community-server-5.7.35-1.el7.x86_64.rpm

Start and enable MySQL at boot:

systemctl start mysqld
systemctl enable mysqld

Retrieve the temporary root password:

grep 'temporary password' /var/log/mysqld.log

Log in and update the root password:

ALTER USER 'root'@'localhost' IDENTIFIED BY 'NewStrongPassword123!';

Grant remote access if needed (optional):

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'NewStrongPassword123!' WITH GRANT OPTION;
FLUSH PRIVILEGES;

Final, import your application’s SQL schema:

mysql -u root -p < /path/to/your-schema.sql

Deploy the Application

Place your WAR file into Tomcat’s webapps directory:

cp myapp.war /opt/apache-tomcat-8.5.20/webapps/

Restart Tomcat to deploy:

service tomcat restart

The application should now be accessible at http://<server-ip>:8080/myapp.
