While following this tutorial on installing tomcat on CentOS I came across a problem executing the line
sudo systemctl enable tomcat - it complains with the following error message:
The unit files have no installation config (WantedBy, RequiredBy, Also, Alias settings in the [Install] section, and DefaultInstance for template units). This means they are not meant to be enabled using systemctl.
However, I clearly have an entry in my [Install] section:
[Unit] Description=Tomcat 9 servlet container After=network.target [Service] Type=forking User=tomcat Group=tomcat Environment="JAVA_HOME=/usr/lib/jvm/jre" Environment="JAVA_OPTS=-Djava.security.egd=file:///dev/urandom" Environment="CATALINA_BASE=/opt/tomcat/latest" Environment="CATALINA_HOME=/opt/tomcat/latest" Environment="CATALINA_PID=/opt/tomcat/latest/temp/tomcat.pid" Environment="CATALINA_OPTS=-Xms256M -Xmx512M -server -XX:+UseParallelGC" ExecStart=/opt/tomcat/latest/bin/startup.sh ExecStop=/opt/tomcat/latest/bin/shutdown.sh [INSTALL] WantedBy=multi-user.target
How can I get it to allow me to enable this service? I believe I've done everything right that it's asking for.
