netstat 找不到命令

报错

[root@stars ~]# netstat -an | grep -iw "listen"
-bash: netstat: command not found

解决思路

[root@stars ~]# yum search netstat

============================= Matched: netstat ==============================
dstat.noarch : Versatile resource statistics tool
net-snmp.x86_64 : A collection of SNMP protocol tools and libraries
net-tools.x86_64 : Basic networking tools


通过yum search 这个命令发现netstat这个命令是在net-tools.x86_64这个包里
接下来下载这个包即可

[root@stars ~]# yum install -y net-tools.x86_64 


再次执行命令
[root@stars ~]# netstat -an | grep -iw "listen"
