Solr正在运行，但systemctl状态为非活动

我已经使用Salt在Amazon Linux V2实例上安装了Solr，它运行良好：

[root@ip-10-231-93-23[gtndorctq-solrms-1-1-v2] ec2-user]# service solr status
su: warning: cannot change directory to /home/solr: No such file or directory

Found 1 Solr nodes: 

Solr process 15691 running on port 8983
{
  "solr_home":"/database/solr/data",
  "version":"6.6.3 d1e9bbd333ea55cfa0c75d324424606e857a775b - sarowe - 2018-03-02 15:09:34",
  "startTime":"2020-06-02T13:19:30.722Z",
  "uptime":"0 days, 0 hours, 35 minutes, 4 seconds",
  "memory":"50.6 MB (%10.3) of 490.7 MB"}

但当我执行systemctl时，它会抛出错误：

[root@ip-10-231-93-23[gtndorctq-solrms-1-1-v2] ec2-user]# systemctl status solr

有关故障的更多信息，当我运行

journalctl-xe

命令时，它表示进程15691正在使用端口8983，但这与由于我的安装而启动的进程相同：

我的systemd文件如下所示，在该文件中，状态

start solr

失败

  file.managed:

似乎

systemd

放弃启动您的服务，因为它尝试绑定到已占用的端口。为了让systemd服务运行，您可能需要出于某种原因杀死驻留在内存中的一些并发进程

我怀疑您提到的进程15691不是由

systemd

控制的进程，看起来

控制的进程。是的，我注意到在安装Solr后，它默认启动，所以我先停止，然后通过systemd启动，现在问题解决了。
