Linux & Mac 常用命令
端口相关
查看端口被那个进程占用
比如 Mac 查看 8080 端口被那个进程占用
bash
# 格式:lsof -i :端口
# -P 用数字显示端口
# -n 不使用主机名,用 ip 显示
lsof -Pn -i :8080
输出:
console
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
nginx 49352 chenlb 6u IPv4 0xa307c62d2d572fc7 0t0 TCP *:8080 (LISTEN)
nginx 54626 chenlb 6u IPv4 0xa307c62d2d572fc7 0t0 TCP *:8080 (LISTEN)
比如 Linux 查看端口被那个进程占用
bash
# -n 不使用主机名,用 ip 显示
# -t 只查看 tcp
# -l 只看监听的端口
# -p 显示进程ID/名
netstat -ntlp
console
Usage: netstat [-ral] [-tuwx] [-enWp]

查看开启了那些端口
Linux 开启了那些端口,如上。
Mac 开启了那些端口:
bash
# -n 不使用主机名,用 ip 显示
# -L 只看监听的端口
netstat -anL
# -p 协议类型 tcp
# netstat -an -p tcp | grep LISTEN
console
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]
结果:
console
