Set up Apache Tomcat 10 on Ubuntu 22.04 with Nginx. Apache Tomcat is an open supply net server and a servlet container which is especially used to server Java primarily based purposes.
On this information you’ll learn to set up Apache Tomcat 10 on Ubuntu 22.04 and safe the setup with Nginx and Let’s Encrypt SSL.
Conditions
- A server with Ubuntu 22.04 OS
- A person with sudo privileges.
Preliminary Setup
Begin by updating the server packages to the most recent model obtainable.
sudo apt replace sudo apt dist-upgrade -y
Create New Person for Tomcat
It will be higher if Tomcat runs because it’s personal unprivileged person. Execute the next command to create a brand new person with required privileges for Tomcat. This person wont be allowed to be logged in to SSH.
sudo useradd -m -d /decide/tomcat -U -s /bin/false tomcat
Set up Java
Set up default JDK utilizing the beneath command. Examine right here for extra detailed guide to install Java.
sudo apt set up default-jdk
As soon as the set up is accomplished, test the model utilizing the next command.
java -version
Your output needs to be much like the one beneath.
openjdk model "11.0.15" 2022-04-19 OpenJDK Runtime Atmosphere (construct 11.0.15+10-Ubuntu-0ubuntu0.22.04.1) OpenJDK 64-Bit Server VM (construct 11.0.15+10-Ubuntu-0ubuntu0.22.04.1, combined mode, sharing)
Set up Apache Tomcat
Obtain the most recent model of Tomcat from their official downloads page. Select the tar.gz below the core part.
Obtain the archive utilizing wget.
cd ~/ wget https://dlcdn.apache.org/tomcat/tomcat-10/v10.0.21/bin/apache-tomcat-10.0.21.tar.gz
Extract the contents to /decide/tomcat listing.
sudo tar xzvf apache-tomcat-10*tar.gz -C /decide/tomcat --strip-components=1
Configure appropriate permissions for Tomcat information.
sudo chown -R tomcat:tomcat /decide/tomcat/ sudo chmod -R u+x /decide/tomcat/bin
Configure Admin Customers
Now we have to setup customers who can entry the Host supervisor and the Supervisor pages in Tomcat.
Add the customers with passwords in /decide/tomcat/conf/tomcat-users.xml
sudo nano /decide/tomcat/conf/tomcat-users.xml
Add the next strains earlier than the tip tag.
<function rolename="manager-gui" /> <person username="supervisor" password="secure_password" roles="manager-gui" /> <function rolename="admin-gui" /> <person username="admin" password="secure_password" roles="manager-gui,admin-gui" />
Now now we have 2 customers who can entry the Supervisor and the Host supervisor pages.
Configure Tomcat as a Service
Right here we’ll configure a systemd service to handle Tomcat to start out, cease and restart mechanically.
Notice the Java location.
sudo update-java-alternatives -l
Output java-1.11.0-openjdk-amd64 1111 /usr/lib/jvm/java-1.11.0-openjdk-amd64
Create a systemd file.
sudo nano /and so forth/systemd/system/tomcat.service
Add the next contents to the file.
[Unit]
Description=Tomcat
After=community.goal
[Service]
Sort=forking
Person=tomcat
Group=tomcat

ExecStart=/decide/tomcat/bin/startup.sh
ExecStop=/decide/tomcat/bin/shutdown.sh
RestartSec=10
Restart=all the time
[Install]
WantedBy=multi-user.goal
Change JAVA_HOME variable with the one you famous earlier than.
Reload systemd daemon for the adjustments to take impact.
sudo systemctl daemon-reload
Begin Tomcat.
sudo systemctl begin tomcat
Allow Tomcat to start out at system boot.
sudo systemctl allow tomcat
Examine Tomcat standing.
sudo systemctl standing tomcat
Output
● tomcat.service - Tomcat

Set up Nginx
Set up Nginx utilizing the next command.
sudo apt set up nginx
Take away default configurations
sudo rm /and so forth/nginx/sites-available/default sudo rm /and so forth/nginx/sites-enabled/default
Configure Nginx Proxy for Tomcat
Create new Nginx configuration
sudo nano /and so forth/nginx/sites-available/yourdomainname.conf
Paste the next
server {
pay attention [::]:80;
pay attention 80;
server_name yourdomainname.com www.yourdomainname.com;
location / {
proxy_pass http://localhost:8080;
proxy_http_version 1.1;
proxy_set_header Improve $http_upgrade;
proxy_set_header Connection 'improve';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}
Save and exit the file.
Allow your configuration by making a symbolic hyperlink.
sudo ln -s /and so forth/nginx/sites-available/yourdomainname.conf /and so forth/nginx/sites-enabled/yourdomainname.conf
Set up Let’s Encrypt SSL with Certbot
Set up Certbot package deal.
sudo apt set up python3-certbot-nginx
Set up SSL certificates utilizing the beneath command.
sudo certbot --nginx --redirect --no-eff-email --agree-tos -m [email protected] -d yourdomainname.com -d www.yourdomainname.com
In case your area is pointed to the server the free SSL certificates will get put in and HTTP to HTTPS redirection will get configured mechanically and Nginx will get restarted by itself for the adjustments to take impact.
If you wish to restart you may test your Nginx configuration and restart it.
sudo nginx -t sudo service nginx restart
Put together your self for a task working as an Information Technology Professional with Linux working system
Confirm Tomcat Set up
Now test your area in your browser.
Click on Supervisor App, you may be prompted to enter username and password. Use the one now we have configured within the Tomcat customers part.
You may also have a look on the Host Supervisor web page.
You may also view the server standing.
Conclusion
Now you will have discovered how one can set up Apache Tomcat on Ubuntu 22.04 and safe with Nginx and Let’s Encrypt SSL..
Thanks on your time. Should you face any drawback or any suggestions, please depart a remark beneath.
