Tomcat 9没有tomcat.pid文件

Question

我在Ubuntu18.04上安装了Tomcat 9，并试图将它添加到服务中。

[Unit]
Description=Apache Tomcat 9 Servlet Container
After=syslog.target network.target

[Service]
User=nblizz
Group=nblizz
Type=forking
Environment=CATALINA_PID=/opt/apache-tomcat-9.0.16/tomcat.pid <--- !! (Not exist)
Environment=CATALINA_HOME=/opt/apache-tomcat-9.0.16
Environment=CATALINA_BASE=/opt/apache-tomcat-9.0.16
ExecStart=/opt/apache-tomcat-9.0.16/bin/startup.sh
ExecStop=/opt/apache-tomcat-9.0.16/bin/shutdown.sh
Restart=on-failure

[Install]
WantedBy=multi-user.target

运行tomcat是可以的，但是在停止Tomcat时会显示错误消息。

另外，apache-tomcat.service文件的颜色与其他文件不同。(https://i.stack.imgur.com/WnD3Y.png)

有什么问题吗？

看起来catalina.sh文件中的v9.0.14发生了变化

$ diff bin/catalina.sh ../tomcats/apache-tomcat-9.0.14/bin/catalina.sh

479c479

<       2\>\&1 \&\& echo \$! \>\“$catalina_pid_file\” \; \} $catalina_out_command “&”

>       2\>\&1 \& echo \$! \>\“$catalina_pid_file\” \; \} $catalina_out_command “&”

489c489

<       2\>\&1 \&\& echo \$! \>\“$catalina_pid_file\” \; \} $catalina_out_command “&”

>       2\>\&1 \& echo \$! \>\“$catalina_pid_file\” \; \} $catalina_out_command “&”

如果移除额外的符号，pid文件将按预期的方式创建。
