For Java 11, 17, and all future LTS releases of Java, App Service provides the Microsoft Build of OpenJDK. On Azure App Service, the binaries for Java 8 are provided from Eclipse Temurin. To obtain your current Java version, sign in to your production server and run the following command: java -version from a specific IP address (as in the previous step).This validation is especially important if your current server is running on an unsupported JDK (such as Oracle JDK or IBM OpenJ9). Start by opening the file with the command: sudo nano /opt/tomcat/latest/webapps/host-manager/META-INF/context.xmlĤ. Repeat the same process for the host-manager file. To allow access from a specific IP address, add the IP to the previous command, as follows: ģ. To make it publicly accessible, add the following lines to the file: ī. Next, decide whether to grant access from a. First, open the manager file: sudo nano /opt/tomcat/webapps/manager/META-INF/context.xmlĢ. By default, Tomcat is only accessible from the local machine.ġ. Step 10: Configure Remote Accessįinally, you need to configure remote access. Make sure to replace the Your_Password value with a strong password of your preference.ģ. Delete everything from the file and add the following: ĭescription=Apache Tomcat Web Application ContainerĮnvironment="JAVA_HOME=/usr/lib/jvm/java-1.11.0-openjdk-amd64"Įnvironment="JAVA_OPTS=file:///dev/urandom =true"Įnvironment="CATALINA_PID=/opt/tomcat/temp/tomcat.pid"Įnvironment="CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC"Ģ. Once the file opens, copy and paste the content below, changing the JAVA_HOME value to the information you found in the previous step. Create and open a new file in the /etc/system/system under the name rvice: sudo nano /etc/systemd/system/rviceģ. With that, you can move on to create the service file.Ģ. Accordingly, it also shows two paths displaying their location.Ĭhoose the version you want to use and copy its location. In the terminal, type: sudo update-java-alternatives -lĪs the output shows, there are two available versions of Java. To do so, prompt the system to give you information about the Java packages installed on the system. This is the exact location of the Java installation package. To configure the file, you first need to find the JAVA_HOME path. Since you are going to to use Tomcat as a service, you need to create a systemd service file.ġ. Lastly, change script permissions to grant execute access in /opt/tomcat/bin/with: sudo sh -c 'chmod +x /opt/tomcat/bin/*.sh' Step 7: Create System Unit File Grant group and user ownership over the installation directory to the tomcat group and user with the command: sudo chown -RH tomcat: /opt/tomcatģ. Move to the directory where the Tomcat installation is located: cd /opt/tomcatĢ. You need to setup execute privileges over the directory.ġ. The new Tomcat user you created does not have executable privileges, but it needs to access the installation directory. Then, extract the file in the new directory with the following command: sudo tar xzvf apache-tomcat-9*tar.gz -C /opt/tomcat -strip-components=1 Step 6: Modify Tomcat User Permission To extract the tar.gz Tomcat file, create a new /opt/tomcat/ directory with the command: sudo mkdir /opt/tomcatĢ.
