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 -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] ➜ AutocarData which netstat /usr/sbin/netstat </code>
然后这个
netstat -atunl
有输出：
<code>➜ AutocarData netstat -atunl Active LOCAL (UNIX) domain sockets Address Type Recv-Q Send-Q Inode Conn Refs Nextref Addr e4d24cdcae041aaf stream 0 0 0 e4d24cdcae042027 0 0 /var/folders/46/2hjxz38n22n3ypp_5f6_p__00000gn/T/iTerm2-temp-socket.jhBJgA e4d24cdcae042027 stream 0 0 0 e4d24cdcae041aaf 0 0 e4d24cdcae04353f stream 0 0 0 e4d24cdcae041857 0 0 /var/run/mDNSResponder e4d24cdcae041857 stream 0 0 0 e4d24cdcae04353f 0 0 e4d24cdcae042d6f stream 0 0 0 e4d24cdcae0436cf 0 0 /var/run/mDNSResponder e4d24cdcae0436cf stream 0 0 0 e4d24cdcae042d6f 0 0 e4d24cdcae0413a7 stream 0 0 0 e4d24cdcae041dcf 0 0 /var/run/mDNSResponder e4d24cdcae041dcf stream 0 0 0 e4d24cdcae0413a7 0 0 e4d24cdcae042ca7 stream 0 0 0 e4d24cdcae04272f 0 0 e4d24cdcae04272f stream 0 0 0 e4d24cdcae042ca7 0 0 e4d24cdcae042e37 stream 0 0 0 e4d24cdcae042fc7 0 0 /var/run/mDNSResponder e4d24cdcae042fc7 stream 0 0 0 e4d24cdcae042e37 0 0 e4d24cdcae041537 stream 0 0 0 e4d24cdcae0416c7 0 0 /var/run/mDNSResponder e4d24cdcae0416c7 stream 0 0 0 e4d24cdcae041537 0 0 e4d24cdcaeeed2e7 stream 0 0 0 e4d24cdcaeeeb087 0 0 /var/run/mDNSResponder ... </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 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：

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 tcp4 0 0 *.25555 *.* LISTEN 131072 131072 46971 0 ➜ AutocarData netstat -anv | grep phantomjs </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 tcp4 0 0 *.5000 *.* LISTEN tcp4 0 0 127.0.0.1.23333 *.* LISTEN tcp4 0 0 *.25555 *.* LISTEN tcp6 0 0 *.58629 *.* LISTEN tcp4 0 0 *.58629 *.* LISTEN tcp6 0 0 ::1.1089 *.* LISTEN tcp4 0 0 127.0.0.1.1089 *.* LISTEN tcp4 0 0 127.0.0.1.1086 *.* LISTEN tcp4 0 0 127.0.0.1.631 *.* LISTEN tcp6 0 0 ::1.631 *.* LISTEN tcp4 0 0 127.0.0.1.4301 *.* LISTEN tcp4 0 0 127.0.0.1.4300 *.* LISTEN tcp4 0 0 10.108.133.227.5786 *.* LISTEN tcp4 0 0 *.32445 *.* LISTEN tcp4 0 0 127.0.0.1.53939 *.* LISTEN tcp4 0 0 *.49629 *.* LISTEN tcp4 0 0 *.49622 *.* LISTEN tcp4 0 0 *.49619 *.* LISTEN tcp4 0 0 127.0.0.1.63342 *.* LISTEN tcp4 0 0 127.0.0.1.1087 *.* LISTEN tcp4 0 0 127.0.0.1.6942 *.* LISTEN </code>
然后去看lsof的help：
<code>➜ ~ lsof --help lsof: illegal option character: - lsof: illegal option character: e lsof: no process ID specified lsof 4.89 latest revision: ftp://lsof.itap.purdue.edu/pub/tools/unix/lsof/ latest FAQ: ftp://lsof.itap.purdue.edu/pub/tools/unix/lsof/FAQ latest man page: ftp://lsof.itap.purdue.edu/pub/tools/unix/lsof/lsof_man usage: [-?abhlnNoOPRtUvV] [+|-c c] [+|-d s] [+D D] [+|-f[cgG]] [-F [f]] [-g [s]] [-i [i]] [+|-L [l]] [+|-M] [-o [o]] [-p s] [+|-r [t]] [-s [p:s]] [-S [t]] [-T [t]] [-u s] [+|-w] [-x [fl]] [--] [names] Defaults in parentheses; comma-separated set (s) items; dash-separated ranges. -?|-h list help -a AND selections (OR) -b avoid kernel blocks -c c cmd c ^c /c/[bix] +c w COMMAND width (9) +d s dir s files -d s select by FD set +D D dir D tree *SLOW?* -i select IPv[46] files -l list UID numbers -n no host names -N select NFS files -o list file offset -O no overhead *RISKY* -P no port names -R list paRent PID -s list file size -t terse listing -T disable TCP/TPI info -U select Unix socket -v list version info -V verbose search +|-w Warnings (+) -- end option scan +f|-f +filesystem or -file names +|-f[cgG] Ct flaGs -F [f] select fields; -F? for help +|-L [l] list (+) suppress (-) link counts < l (0 = all; default = 0) +|-M portMap registration (-) -o o o 0t offset digits (8) -p s exclude(^)|select PIDs -S [t] t second stat timeout (15) -T fqs TCP/TPI Fl,Q,St (s) info -g [s] exclude(^)|select and print process group IDs -i i select by IPv[46] address: [46][proto][@host|addr][:svc_list|port_list] +|-r [t[m<fmt>]] repeat every t seconds (15); + until no files, - forever.

【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。
