systemctl如何根据pid寻找具体哪个服务

家里折腾我家云omv系统, 

一直有个进程 2105 aria2c --conf-path=/opt/etc/aria2.conf

在写emmc文件...一会就写满了...

 

需要利用systemctl disable 该项服务, 以解决该问题...

root@omv:/opt# systemctl --help | grep -i pid
  status [PATTERN...|PID...]      Show runtime status of one or more units
  help PATTERN...|PID...          Show manual for one or more units

root@omv:/opt# systemctl status 2105

ok, 可以看到是rc-local.service...

root@omv:/opt/bin# systemctl stop rc-local.service
