1. 先根據進程名查看進程id
ps aux | grep 進程名(或者ps -ef | grep 進程名)
y@ubuntu:~$ ps aux | grep bitcoind
y 2708 101 12.1 1611172 488580 ? Ssl Aug22 32:04 bitcoind -daemon -connect=172.16.247.139
y 3564 0.0 0.0 21536 1092 pts/0 S+ 00:23 0:00 grep --color=auto bitcoind
可以看到，bitcoind進程的pid是2708
2.通過進程id查看占用的端口
netstat -nap | grep 進程id
y@ubuntu:~$ netstat -nap | grep 2708
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
tcp 0 0 127.0.0.1:8332 0.0.0.0:* LISTEN 2708/bitcoind
tcp6 0 0 ::1:8332 :::* LISTEN 2708/bitcoind
可以看到，pid=2708的進程占用的端口號是8332
3.通過端口號查看占用的進程id
netstat -nap | grep 端口號
y@ubuntu:~$ netstat -nap | grep 8332
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
tcp 0 0 127.0.0.1:8332 0.0.0.0:* LISTEN 2708/bitcoind
tcp6 0 0 ::1:8332 :::* LISTEN 2708/bitcoind
可以看到，占用8332端口的是進程的pid是2708，名稱是bitcoind
