我在 RHEL 7.2 服务器上安装了 Apache Httpd 2.4.6 和 Tomcat 7.0.54，配置了 AJP 连接器和 SSL，并启用了 SELinux。
当我启动 Tomcat 服务器时，一切都开始正常，Web 应用程序也工作正常。但是过一会儿，如果您运行 # service tomcat status 或 systemctl status tomcat ，我会得到以下输出。
[root@ip-xxx-xxx-xxx-xxx logs]# service tomcat status
Redirecting to /bin/systemctl status tomcat.service

我在 Tomcat 日志中没有看到任何错误。将 SELinux 设置为 permissive 并不能解决问题。 如何诊断问题并解决问题？
最佳答案
systemctl status tomcat 的问题在于它只会显示来自服务的最新日志条目
journalctl -x -u tomcat 将显示上次日志轮换的日志条目。
关于 systemctl 的更多信息和 journalctl
关于java - systemctl status tomcat 返回 org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java :950)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/36204889/
