Wait for the process to finish. And kill the process because it remains.
prologue
When I did yum install, the process remained, so I just solved it
environment
[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 8.2.2004 (Core)
procedure
[root@localhost ~]# yum install bind
Wait for the process at pid 5016 to terminate.
“It will never end …”
[root@localhost ~]# ps|grep "5016"
5016 pts/0 00:00:04 yum
“I’m not going. Will you kill me?”
[root@localhost ~]# kill 5016
[root@localhost ~]# echo $?
0
[root@localhost ~]# ps|grep "5016"
5016 pts/0 00:00:04 yum
“If you don’t die …”
[root@localhost ~]# kill -s 9 5016
[1]+Forced termination yum install bind
[root@localhost ~]# ps|grep "5016"
(End)
epilogue
The return of kill was 0, but it was alive for some reason, so it was killed.
