Tomcat不能在CentOs上工作-execstop=/bin/kill-15$mainpid(code=exited，status=1/failure)

Question

我哪里出错了？我应该在哪个日志文件中查找问题？

*（如果我使用tomcat 9.0.14，我在catalina.out：OpenJDK 64位服务器VM警告中有一条错误消息：如果处理器的数量预计将从一个增加，那么您应该使用-xx：parallelgcthreads=n配置并行GC线程的数量，但是我可以在14.point配置文件（/etc/systemd/system/tomcat.service）中更改以下内容来修复它：

-XX:ParallelGCThreads=N 

[root@centos-s-1vcpu-1gb-ams3-01 ~]# java -version
openjdk version "1.8.0_191"
OpenJDK Runtime Environment (build 1.8.0_191-b12)
OpenJDK 64-Bit Server VM (build 25.191-b12, mixed mode)

wget http://xenia.sote.hu/ftp/mirrors/www.apache.org/tomcat/tomcat-8/v8.5.37/bin/apache-tomcat-8.5.37.tar.gz

tar xzf apache-tomcat-8.5.37.tar.gz

mv apache-tomcat-8.5.37/ /opt/tomcat

4.

groupadd tomcat

5.

useradd -g tomcat -M -d /opt/tomcat -s /bin/nologin tomcat

6.

chgrp -R tomcat /opt/tomcat/ 

chmod -R g+r /opt/tomcat/conf

chmod -R g+x /opt/tomcat/conf

chown -R tomcat /opt/tomcat/webapps/

chown -R tomcat /opt/tomcat/work/

chown -R tomcat /opt/tomcat/temp/

12.

chown -R tomcat /opt/tomcat/logs/

13.

vi /etc/systemd/system/tomcat.service

大约1,5年后，“他们”（Linux论坛）告诉我CentOS上有一个bug，我应该改变操作系统版本。
