Tomcat starts successfully when run from the tomcat user in RHEL 9.3 using $CATALINA_HOME/bin/startup.sh. I am using for my java:
java version "21.0.2" 2024-01-16 LTS Java(TM) SE Runtime Environment (build 21.0.2+13-LTS-58) Java HotSpot(TM) 64-Bit Server VM (build 21.0.2+13-LTS-58, mixed mode, sharing)
I have created a service, called tomcat.service under /usr/lib/systemd/system thus:
[Unit]
Description=Tomcat webserver
Wants=network.target
After=network.target
[Service]
Type=simple
Environment=JAVA_HOME=/usr/lib/jvm/jdk-21-oracle-x64

Environment=CLASSPATH=$CATALINA_HOME/lib
Environment='CATALINA_OPTS=-Xms512M -Xmx1G -Djava.net.preferIPv4Stack=true'
Environment='JAVA_OPTS=-Djava.awt.headless=true'
User=tomcat
Group=tomcat
ExecStart=/home/tomcat/apache-tomcat-9.0.85/bin/startup.sh
ExecStop=/home/tomcat/apache-tomcat-9.0.85/bin/shutdown.sh
SuccessExitStatus=143
[Install]
WantedBy=multi-user.target
This fails with the strange error:
startup.sh[317989]: touch: cannot touch '$CATALINA_HOME/logs/catalina.out': No such file or directory startup.sh[317983]: /home/tomcat/apache-tomcat-9.0.85/bin/catalina.sh: line 504: $CATALINA_HOME/logs/catalina.out: No such>
I've checked and the CATALINA_HOME/logs/catalina.out file exists and is owned by tomcat
Clearly the service must have successfully started the startup.sh script, but for some reason seems to be having issues trying to write to this file
Any suggestions gratefully accepted
Expected the service to start as executing the script did
