代码语言：javascript复制[root@node1 elastic]# ps -ef|grep kibana
root 24796 24763 0 16:16 pts/0 00:00:00 grep --color=auto kibana
[root@node1 elastic]# kill 24796
bash: kill: (24796) - No such process
[root@node1 elastic]# 关闭失败，原因该命令无法查询到kibana的PID
2、解决办法1
尝试下面命令
代码语言：javascript复制[elastic@node1 kibana-5.6.5]$ fuser -n tcp 5601
5601/tcp: 24001
[elastic@node1 kibana-5.6.5]$ kill 24001
[elastic@node1 kibana-5.6.5]$ jps
25104 Jps
24941 Elasticsearch
[1] Terminated bin/kibana
[elastic@node1 kibana-5.6.5]$ 3、解决办法2
代码语言：javascript复制[elastic@node1 ~]$ ps -ef | grep node
