【已解决】Mac中如何查看正在使用的端口及其进程ID

Mac crifan 1441浏览 0评论

折腾:

【已解决】pyspider运行出错:Error Could not create web server listening on port 25555

期间,网上都说用:

netstat的-atunlp参数去查看:

<code>netstat -atunlp
</code>

但是此处是Mac,却出错:

<code>➜  AutocarData netstat -atunlp
netstat: option requires an argument -- p
Usage:    netstat [-AaLlnW] [-f address_family | -p protocol]
    netstat [-gilns] [-f address_family]
    netstat -i | -I interface [-w wait] [-abdgRtS]
    netstat -s [-s] [-f address_family | -p protocol] [-w wait]
    netstat -i | -I interface -s [-f address_family | -p protocol]
    netstat -m [-m]
    netstat -r [-Aaln] [-f address_family]
    netstat -rs [-s]
</code>

去看看help说明:

好像Mac中的netstat是简化版本,参数支持的不多?

<code>➜  AutocarData netstat --help
netstat: illegal option -- -
Usage:    netstat [-AaLlnW] [-f address_family | -p protocol]
    netstat [-gilns] [-f address_family]
    netstat -i | -I interface [-w wait] [-abdgRtS]

    netstat -i | -I interface -s [-f address_family | -p protocol]
    netstat -m [-m]
    netstat -r [-Aaln] [-f address_family]
    netstat -rs [-s]

➜  AutocarData which netstat
/usr/sbin/netstat
</code>

然后这个

netstat -atunl

有输出:

</code>

但是关键是此处没有搜到25555和phantomjs:

<code>➜  AutocarData netstat -atunl | grep 25555
➜  AutocarData netstat -atunl | grep phantomjs
</code>

看来先要去学习:

Mac中netstat的语法和可用的参数了

netstat 语法 mac

Mac查看端口占用情况 – 破男孩 – 博客园

Mac OS/Linux命令查询网络端口占用情况 – 猫哥_kaiye – 博客园

用-an参数

<code>➜  AutocarData netstat -an | grep 25555
tcp4       0      0  *.25555                *.*                    LISTEN
➜  AutocarData netstat -an | grep phantomjs
</code>

使用 lsof 代替 Mac OS X 中的 netstat 查看占用端口的程序 | TonyDeng’s Blog

而此处Mac中用:

<code>➜  AutocarData lsof -i:25555
COMMAND     PID   USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
phantomjs 46971 crifan   12u  IPv4 0xe4d24cdcaf5e481f      0t0  TCP *:25555 (LISTEN)
</code>

可以达到目的了:

的确看到是phantomjs占用了25555号端口,且PID也看到了。

但是上面竟然netstat中没有看到phantomjs。

还是想要搞清楚Mac中到底能不能用netstat输出对应的,带phantomjs的信息。

所以先去看看netstat本身的语法:

netstat 语法

试了半天都不行:

找到了Mac中的写法不一样:

但是还是没看到有:

phantomjs

Mac netstat show pid

macos – Who is listening on a given TCP port on Mac OS X? – Stack Overflow

都是说用lsof

<code>➜  AutocarData netstat -anv | grep 25555

</code>

Finding the pid listening on a specific port on Mac OS X – Jayway

networking – How to use netstat to show what process is listening on a port – Super User

参考:

Mac OS X: List listening ports and programs using netstat

解释的比较清楚:

Linux中的:

<code>netstat -pant | grep LISTEN
</code>

而mac中,是不识别的:

<code>➜  ~ netstat -pant | grep LISTEN
netstat: ant: unknown or uninstrumented protocol
</code>

需要用:

<code>netstat -an -ptcp | grep LISTEN
</code>

可以看到端口,但是是看不到program的,因为此处的-p参数只是protocl,不是program:

<code>➜  ~ netstat -an -ptcp | grep LISTEN

然后去看lsof的help:

【总结】

netstat本身的命令,是能找到某个端口的pip的:

比如之前用过的

<code>netstat -lanp | grep 25555
</code>

但是Mac中大netstat是精简版,弱智版本,不支持。

最多能用:

<code>➜  AutocarData netstat -anv | grep 25555
tcp4       0      0  *.25555                *.*                    LISTEN      131072 131072  46971      0
</code>

看到端口,但是不知道是谁占用的。更不知道其pid。

mac中可以用lsof:

<code>➜  AutocarData lsof -i:25555
COMMAND     PID   USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
phantomjs 46971 crifan   12u  IPv4 0xe4d24cdcaf5e481f      0t0  TCP *:25555 (LISTEN)
</code>

即可看出:

是phantomjs占用了2555端口。

pid是46971

-》后续就可以用kill去杀掉这个应用了。
