Hello All,

I’m trying to deploy DHIS2 in a AWS EC2 instance. I have completed each and every step mentioned in the official documentation. But when go to [http://mypublicip:8080](http://mypublicip:8080), I’m getting the 404 error. I have given all of my configuration files below. Any help is highly appreciated!

My environment:  
OS: Ubuntu 22.04 LTS  
PostgreSQL 15  
Tomcat9  
Java: OpenJDK 11  
DHIS2 Version: 2.36

config files:

1. dhis.conf (/home/dhis/config/)

# Hibernate SQL dialect

connection.dialect = org.hibernate.dialect.PostgreSQLDialect

# JDBC driver class

connection.driver\_class = org.postgresql.Driver

# Database connection URL

connection.url = jdbc:postgresql:dhis2

# Database username

connection.username = dhis

# Database password

connection.password = xxxx

# Database schema behavior, can be validate, update, create, create-drop

connection.schema = update

# Encryption password (sensitive)

encryption.password = xxxx

1. Startup file: (/home/dhis/tomcat-dhis/bin)  
#!/bin/sh  
set -e  
if [“$(id -u)” -eq “0”]; then  
echo “This script must NOT be run as root” 1\>&2  
exit 1  
fi  
export CATALINA\_BASE=“/home/dhis/tomcat-dhis”  
/usr/share/tomcat9/bin/startup.sh  
echo “yes, Tomcat started”

2. Setenv.sh (/home/dhis/tomcat-dhis/bin)  
#!/bin/sh

# 

CATALINA\_HOME=/usr/share/tomcat9

# Find the Java runtime and set JAVA\_HOME

. /usr/libexec/tomcat9/tomcat-locate-java.sh

# Default Java options

if [-z “$JAVA\_OPTS”]; then  
JAVA\_OPTS=“-Djava.awt.headless=true”  
fi  
JAVA\_HOME=‘/usr/lib/jvm/java-11-openjdk-amd64/’  
JAVA\_OPTS=‘-Xms4000m -Xmx7000m’  
DHIS2\_HOME=‘/home/dhis/config’

This is what i get when i start tomcat:

I am happy to provide any more information that is required here 🙂

@e4eDHIS2 :Please not that recently I was trying out with multiple versions of DHIS2 to see which one works. So some of the error can be because of that.

@amalg what’s your database name (not username)? Also, did you drop the database before deploying the new versions?

Hi @amalg,

Can you go through the steps again from here?

Hello @julhas ,

Thank you so much for your help. It did worked out at the end. Just out of my curiosity, what changes do you think worked out for me? I’m only able to see these changes from my previous installations:

1.Ubuntu 20.04 LTS instead of 22.04 LTS  
2.Tomcat instance was in /var/www instead of /home/dhis  
3. Tomcat: 9, PostgreSQL 12, Java 11 (OpenJDK 11) and DHIS 2.37

Hello @amalg,

I’m happy to hear that it went smoothly. I believe there was a problem with the DHIS2 version.

Please contact me at [info@jaetech.co](mailto:info@jaetech.co) if you require any assistance with the implementation of your project, including any external dashboard visualizations or DHIS2 custom web application development.

Julhas
