Apache Tomcat is an open-source implementation of the Java Servlet, JavaServer Pages, Java Expression Language, and Java WebSocket technologies. Nginx is a high-performance web server that can also be used as a reverse proxy. This tutorial will guide you through the process of installing Apache Tomcat 10 with Nginx acting as a reverse proxy on Debian 12.<\/p>\n
Before you begin, ensure you have:<\/p>\n
Apache Tomcat requires Java to be installed on your system. Install OpenJDK 11:<\/p>\n
sudo apt update\r\nsudo apt install default-jdk -y\r\n<\/code><\/pre>\nStep 2: Install Apache Tomcat<\/h2>\n
Download and install Apache Tomcat 10:<\/p>\n
cd \/tmp\r\nwget https:\/\/downloads.apache.org\/tomcat\/tomcat-10\/v10.0.16\/bin\/apache-tomcat-10.0.16.tar.gz\r\nsudo tar -xf apache-tomcat-10.0.16.tar.gz -C \/opt\r\n<\/code><\/pre>\nStep 3: Configure Apache Tomcat<\/h2>\n
Configure Apache Tomcat to run as a service:<\/p>\n
sudo nano \/etc\/systemd\/system\/tomcat.service\r\n<\/code><\/pre>\nAdd the following content:<\/p>\n
[Unit]\r\nDescription=Apache Tomcat Web Application Container\r\nAfter=network.target\r\n\r\n[Service]\r\nType=forking\r\n\r\nEnvironment=JAVA_HOME=\/usr\/lib\/jvm\/default-java\r\nEnvironment=CATALINA_PID=\/opt\/apache-tomcat-10.0.16\/temp\/tomcat.pid\r\nEnvironment=CATALINA_HOME=\/opt\/apache-tomcat-10.0.16\r\nEnvironment=CATALINA_BASE=\/opt\/apache-tomcat-10.0.16\r\n\r\nExecStart=\/opt\/apache-tomcat-10.0.16\/bin\/startup.sh\r\nExecStop=\/opt\/apache-tomcat-10.0.16\/bin\/shutdown.sh\r\n\r\nUser=root\r\nGroup=root\r\nRestart=always\r\n\r\n[Install]\r\nWantedBy=multi-user.target\r\n<\/code><\/pre>\nSave and close the file, then reload systemd:<\/p>\n
sudo systemctl daemon-reload\r\n<\/code><\/pre>\nStart and enable Apache Tomcat:<\/p>\n
sudo systemctl start tomcat\r\nsudo systemctl enable tomcat\r\n<\/code><\/pre>\nStep 4: Install and Configure Nginx<\/h2>\n
Install Nginx:<\/p>\n
sudo apt install nginx -y\r\n<\/code><\/pre>\nCreate a new server block configuration file:<\/p>\n
sudo nano \/etc\/nginx\/sites-available\/tomcat\r\n<\/code><\/pre>\nAdd the following content:<\/p>\n
server {\r\n listen 80;\r\n server_name your_domain.com;\r\n\r\n location \/ {\r\n proxy_pass http:\/\/localhost:8080\/;\r\n proxy_set_header Host $host;\r\n proxy_set_header X-Real-IP $remote_addr;\r\n proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;\r\n proxy_set_header X-Forwarded-Proto $scheme;\r\n }\r\n}\r\n<\/code><\/pre>\nActivate the server block by creating a symbolic link:<\/p>\n
sudo ln -s \/etc\/nginx\/sites-available\/tomcat \/etc\/nginx\/sites-enabled\/\r\n<\/code><\/pre>\nTest Nginx configuration for syntax errors:<\/p>\n
sudo nginx -t\r\n<\/code><\/pre>\nIf the test is successful, reload Nginx to apply the changes:<\/p>\n
sudo systemctl reload nginx\r\n<\/code><\/pre>\nStep 5: Access Apache Tomcat via Nginx<\/h2>\n
Open your web browser and navigate to http:\/\/your_domain.com<\/code>. You should see the Apache Tomcat default landing page, indicating that Nginx is successfully acting as a reverse proxy for Apache Tomcat.<\/p>\nConclusion<\/h2>\n
Congratulations! You have successfully installed Apache Tomcat 10 with Nginx acting as a reverse proxy on Debian 12. You can now deploy your Java web applications and access them via Nginx.<\/p>\n
