我在我的 Ubuntu 18.04 上安装了 Tomcat。
sudo systemctl status tomcat
● tomcat.service - Tomcat 9 servlet container

如何修复此权限问题？
我配置了/etc/systemd/system/tomcat.service
[Unit]
Description=Tomcat 9 servlet container
After=network.target
[Service]
Type=forking
User=tomcat
Group=tomcat
Environment="JAVA_HOME=/usr/bin/java"
Environment="JAVA_OPTS=-Djava.security.egd=file:///dev/urandom -Djava.awt.headless=true"
Environment="CATALINA_BASE=/opt/tomcat/apache-tomcat-9.0.33"
Environment="CATALINA_HOME=/opt/tomcat/apache-tomcat-9.0.33"
Environment="CATALINA_PID=/opt/tomcat/apache-tomcat-9.0.33/temp/tomcat.pid"
Environment="CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC"
ExecStart=/opt/tomcat/latest/bin/startup.sh
ExecStop=/opt/tomcat/latest/bin/shutdown.sh
[Install]
WantedBy=multi-user.target
如何检查为什么没有找到匹配的进程或者当前用户没有权限停止该进程？
