If you need to access the web interface from a remote IP, open the following files and comment or delete the lines marked in the screenshots: sudo vim /opt/tomcat/latest/webapps/manager/META-INF/context.xml
Make sure to change the username and password to something more secure:īy default, Tomcat web admin interface is configured to allow access only from local host. To add a new user who can access the tomcat web interface ( manager-gui and admin-gui) we need define the user at the end of the tomcat-users.xml file as it's shown in the following. sudo vim /opt/tomcat/latest/conf/tomcat-users.xml
#Apache tomcat 9 full
If you open the file, you will see that it is full of comments and examples. Tomcat users and their roles are defined in the file tomcat-users.xml. Now that we have Tomcat 9 installed in our Ubuntu, the next step is create a user who has access to the web administration interface. Sudo ufw allow 8080/tcp Configure Tomcat Web Manager Interface To allow traffic on port 8080 type the following command: This step is dangerous in some situations. If your computer or server is protected by a firewall and you want access the Tomcat interface from outside your local network, you will need to open port 8080. If there are no errors, you can enable the Tomcat service to start automatically at boot time: sudo systemctl enable tomcat Set the Firewall It can check service status with the following command: sudo systemctl status tomcat We will notify systemd that we created a new unit file and we will start the Tomcat service running: sudo systemctl daemon-reload
WantedBy=multi-user.target Check the status of the service This must be saved inside the / etc / systemd / system / directory with the following content:Įnvironment="JAVA_HOME=/usr/lib/jvm/default-java"Įnvironment="JAVA_OPTS=file:///dev/urandom"Įnvironment="CATALINA_BASE=/opt/tomcat/latest"Įnvironment="CATALINA_HOME=/opt/tomcat/latest"Įnvironment="CATALINA_PID=/opt/tomcat/latest/temp/tomcat.pid"Įnvironment="CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC"ĮxecStart=/opt/tomcat/latest/bin/startup.shĮxecStop=/opt/tomcat/latest/bin/shutdown.sh To run Tomcat as a service, we will create a new unit file called rvice. We will have to change the ownership of the directory to tomcat's user and group: sudo chown -R tomcat: /opt/tomcatĪs well we will make the scripts inside the bin directory executable: sudo chmod +x /opt/tomcat/latest/bin/*.sh Create a systemd unit file The tomcat user we set up earlier needs to have access to Tomcat 9 directory.
#Apache tomcat 9 update
Later, if you want to update your Tomcat installation, you can unpack the latest version and change the symlink to point to the latest version.
#Apache tomcat 9 zip file
Once the download is complete, we will extract the zip file and move it to the / opt / tomcat directory: unzip apache-tomcat-*.zipįor, have more control over versions and updates, we will create a symbolic link that will point to the installation directory: sudo ln -s /opt/tomcat/apache-tomcat-* /opt/tomcat/latest When we are clear about the file to download, we will move to / tmp directory and download the zip file with wget. As of this writing, the latest version is 9.0.10. Let's download the latest version of Tomcat 9.0.x since download page.
#Apache tomcat 9 install
We can install them by typing: sudo apt install unzip wget We will use wget and unzip to download and extract the Tomcat 9 file. Now let's create a new system user and group with home directory in / opt / tomcat, which will run the Tomcat service: sudo useradd -m -U -d /opt/tomcat -s /bin/false tomcat Download Tomcat 9 If you prefer to install Oracle Java instead of OpenJDK, see the instructions that a colleague posted some time ago. La installing the OpenJDK package on Ubuntu 18.04 it is quite simple:
