Question

我将Tomcat配置为在CentOS 7.2上使用Systemd作为服务运行。我可以毫无问题地启动Tomcat：

sudo systemctl start tomcat

我可以访问启动画面，管理器应用程序，甚至可以部署应用程序。然后我关闭了Tomcat：

sudo systemctl stop tomcat

我没有看到任何错误。但后来我检查状态：

sudo systemctl status tomcat

● tomcat.service - Apache Tomcat Web Application Container
   Loaded: loaded (/etc/systemd/system/tomcat.service; disabled; vendor preset: disabled)
   Active: failed (Result: exit-code) since Sun 2016-10-30 17:27:19 UTC; 2s ago

它表明kill功能正常。并且/opt/tomcat/logs/catalina.out也没有显示任何问题：

为什么Systemd会考虑Tomcat＆＃34;失败＆＃34;？它与＃34;陈旧的PID文件有什么关系＆＃34;消息？

Answer 1

啊，没关系;对于一般的Java应用程序，这已经answered already on serverfault。

基本上，Java程序有时在关闭以响应SIGTERM时不会发回预期的退出状态。将以下内容添加到tomcat.service文件可以解决问题：

[Service]
SuccessExitStatus=143

Systemd tomcat.service失败，没有错误
