Add yours through the "Deploy" area and then stop/start/undeploy it with the "Applications" area. Once logged in you can see five already deployed web applications. Probably the easiest way is to use the manager webapp Use the username/password you defined as manager in tomcat-users.xml. The manager to administer web applications: The GUI way.The host-manager to handle virtual hosts:.Tomcat is bundled with 5 already deployed web applications (change localhost with your server's FQDN if needed): Be aware that using these scripts prevents the jsvc security advantage described above. In order to be able to use these scripts, some further configuration may be needed. This can be useful to debug applications or even debug Tomcat, but do not use it to start Tomcat for the first time as doing so can set some permissions wrongly and stop web apps from working. Tomcat can also be controlled directly using upstream scripts: See man jsvc for options available and pass them through the CATALINA_OPTS environment variable declared in /etc/conf.d/tomcat n. This also enables the use of ports under 1024 if needed.

This prevents malicious code that could be executed in a bad web application from causing too much damage. Tomcat's systemd service runs this Apache binary with root privileges which itself starts Tomcat with an underprivileged user ( tomcat n:tomcat n in Arch Linux). Note: To improve security, Arch Linux's Tomcat packages use the jsvc binary from Apache's common-daemons.

Google is full of answers on recurrent issues found in Tomcat logs. If the startup script failed or you can only see a Java error displayed in you browser, have a look at startup logs using systemd's journalctl. Once Tomcat is started, you can visit this page to see the result: If a nice Tomcat local home page is displayed this means your Servlet container is up and running and ready to host you web apps. To have read permissions on the configuration files and work well with some IDEs, you must add your user to the tomcat n user group. This blog post gives a good description of these roles. Keep in mind that Tomcat must be restarted each time a modification is made to this file. Here is a bare configuration file that declares some of these roles along with usernames and passwords (Be sure to change the following passwords to something secure): To keep it short, tomcat is the mandatory role used to run, manager-* are roles able to administer web applications and admin-* are full right administrator roles on the Tomcat server. Uncomment the "role and user" XML declaration and modify it to enable roles tomcat, admin-gui, admin-script and/or manager-gui, manager-script, manager-jmx, manager-status depending on your needs (see Configuring Manager Application Access). In order to be able to use the manager webapp and the admin webapp you need to edit /etc/tomcat n/tomcat-users.xml. Where Tomcat deploys your web applications Log files not handled by systemd (see #Logging) Main Tomcat folder containing scripts and links to other directories Among some: tomcat-users.xml (defines users allowed to use administration tools and their roles), server.xml (Main Tomcat configuration file), catalina.policy (security policies configuration file) Replace the n with your installed version (8, 9, 10).Ĭonfiguration files. INFO: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the Using tomcat-native will remove the following warning in catalina.err: More information is available in the official Tomcat docs. No configuration is necessary for default Tomcat installations. It uses native 32- or 64-bit code to enhance performance and is sometimes used in production environments where speed is crucial.

The native library for Tomcat configures the server to use the Apache Portable Runtime (APR) library's network connection (socket) and RNG implementations. If deploying Tomcat onto a production environment, consider installing tomcat-native. Install one of tomcat8, tomcat9, or tomcat10. 7.1 Tomcat service is started, but page is not loaded.6.2 Using Tomcat with a different JRE/JDK.6.1 Migrating from previous versions of Tomcat.4.3 Hosting files outside the webapps folder.
