Here\u2019s a step-by-step guide to installing and configuring Apache Tomcat on AlmaLinux.<\/p>\n\n\n\n

1. Prerequisites: Installing Java<\/h3>\n\n\n\n

Apache Tomcat requires Java to run, so start by installing OpenJDK on your AlmaLinux system.<\/p>\n\n\n\n

Update System Packages<\/h4>\n\n\n\n

Update the package index to ensure you have the latest version of each package:<\/p>\n\n\n\n

sudo dnf update -y<\/code><\/pre>\n\n\n\n
Install Java<\/h4>\n\n\n\n
Use the dnf<\/code> package manager to install the default Java Development Kit (JDK):<\/p>\n\n\n\n
sudo dnf install -y java-11-openjdk<\/code><\/pre>\n\n\n\n
Once installed, verify the Java version to ensure it\u2019s set up correctly:<\/p>\n\n\n\n
java -version<\/code><\/pre>\n\n\n\n
2. Creating a Tomcat User<\/h3>\n\n\n\n
Running Tomcat as the root user isn\u2019t secure, so create a dedicated user for Tomcat with restricted permissions.<\/p>\n\n\n\n
sudo useradd -r -m -U -d \/opt\/tomcat -s \/bin\/false tomcat<\/code><\/pre>\n\n\n\n
This creates a system user named tomcat<\/code>, with its home directory at \/opt\/tomcat<\/code>, which we\u2019ll use as the Tomcat installation directory.<\/p>\n\n\n\n
3. Downloading and Extracting Tomcat<\/h3>\n\n\n\n
Visit the Apache Tomcat download page<\/a> to get the latest version. Here, we\u2019ll use version 9.0.34 as an example.<\/p>\n\n\n\n
Download Tomcat<\/h4>\n\n\n\n
Download the tarball using wget<\/code>:<\/p>\n\n\n\n
wget -c https:\/\/downloads.apache.org\/tomcat\/tomcat-9\/v9.0.34\/bin\/apache-tomcat-9.0.34.tar.gz<\/code><\/pre>\n\n\n\n
Extract the Tomcat Archive<\/h4>\n\n\n\n
After downloading, extract the archive to the \/opt\/tomcat<\/code> directory:<\/p>\n\n\n\n
sudo mkdir \/opt\/tomcat\nsudo tar xf apache-tomcat-9.0.34.tar.gz -C \/opt\/tomcat<\/code><\/pre>\n\n\n\n
To make future updates easier, create a symbolic link named latest<\/code> that points to the Tomcat installation directory:<\/p>\n\n\n\n
sudo ln -s \/opt\/tomcat\/apache-tomcat-9.0.34 \/opt\/tomcat\/latest<\/code><\/pre>\n\n\n\n
Set Permissions<\/h4>\n\n\n\n
Ensure the tomcat<\/code> user has full ownership of the Tomcat directory:<\/p>\n\n\n\n
sudo chown -R tomcat: \/opt\/tomcat
sudo chmod +x \/opt\/tomcat\/latest\/bin\/*.sh<\/code><\/pre>\n\n\n\n
4. Configuring Tomcat as a Systemd Service<\/h3>\n\n\n\n
To run Tomcat as a service on AlmaLinux, create a systemd unit file.<\/p>\n\n\n\n
Create a Unit File<\/h4>\n\n\n\n
Create a new file for the Tomcat service:<\/p>\n\n\n\n
sudo nano \/etc\/systemd\/system\/tomcat.service<\/code><\/pre>\n\n\n\n
Add the following content, adjusting the JAVA_HOME<\/code> path if needed:<\/p>\n\n\n\n
[Unit]\nDescription=Apache Tomcat Web Application Container\nAfter=network.target\n\n[Service]\nType=forking\n\nEnvironment=\"JAVA_HOME=\/usr\/lib\/jvm\/java-11-openjdk\"\nEnvironment=\"CATALINA_PID=\/opt\/tomcat\/latest\/temp\/tomcat.pid\"\nEnvironment=\"CATALINA_HOME=\/opt\/tomcat\/latest\"\nEnvironment=\"CATALINA_BASE=\/opt\/tomcat\/latest\"\nEnvironment=\"CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC\"\nEnvironment=\"JAVA_OPTS=-Djava.awt.headless=true -Djava.security.egd=file:\/dev\/.\/urandom\"\n\nExecStart=\/opt\/tomcat\/latest\/bin\/startup.sh\nExecStop=\/opt\/tomcat\/latest\/bin\/shutdown.sh\n\nUser=tomcat\nGroup=tomcat\nUMask=0007\nRestartSec=10\nRestart=always\n\n[Install]\nWantedBy=multi-user.target\n<\/code><\/pre>\n\n\n\n
Reload the Systemd Daemon<\/h4>\n\n\n\n
Reload systemd to recognize the new Tomcat service file:<\/p>\n\n\n\n
sudo systemctl daemon-reload<\/code><\/pre>\n\n\n\n
Start and Enable the Tomcat Service<\/h4>\n\n\n\n
Now, start the Tomcat service and enable it to start on boot:<\/p>\n\n\n\n
sudo systemctl start tomcat\nsudo systemctl enable tomcat<\/code><\/pre>\n\n\n\n
Verify the Tomcat Service Status<\/p>\n\n\n\n
Check the status to make sure Tomcat is running:<\/p>\n\n\n\n
sudo systemctl status tomcat<\/code><\/pre>\n\n\n\n
5. Configuring the Firewall<\/p>\n\n\n\n
If you have a firewall enabled, allow access to Tomcat\u2019s default port, 8080:<\/p>\n\n\n\n
sudo firewall-cmd --permanent --add-port=8080\/tcp\nsudo firewall-cmd --reload<\/code><\/pre>\n\n\n\n
6. Verifying the Tomcat Installation<\/p>\n\n\n\n
To verify that Tomcat is successfully installed, open a browser and go to the following URL, replacing <YourIPAddress><\/code> with the server\u2019s IP address:<\/p>\n\n\n\n
http://:your_ip_addresss:8080<\/code><\/pre>\n\n\n\n
If everything was configured correctly, you should see the Tomcat default welcome page.<\/p>\n\n\n\n
Optional: Securing the Tomcat Manager and Host Manager<\/h3>\n\n\n\n
    \n
  1. Enable the Tomcat Manager Application<\/strong> by editing the tomcat-users.xml<\/code> file:<\/li>\n<\/ol>\n\n\n\n
    sudo nano \/opt\/tomcat\/latest\/conf\/tomcat-users.xml<\/code><\/pre>\n\n\n\n
       2. Add Roles and a User<\/strong>: Add a user with manager-gui<\/code> and admin-gui<\/code> roles:<\/p>\n\n\n\n
    <role rolename=\"manager-gui\"\/>\n<role rolename=\"admin-gui\"\/>\n<user username=\"admin\" password=\"your_password\" roles=\"manager-gui,admin-gui\"\/><\/code><\/pre>\n\n\n\n
    3. Restart Tomcat<\/strong> to apply changes:<\/p>\n\n\n\n
    sudo systemctl restart tomcat<\/code><\/pre>\n\n\n\n
    You can now log in to the Manager and Host Manager applications using the configured credentials.<\/p>\n\n\n\n
