方法一:
/sbin/ifconfig -a|grep inet|grep -v 127.0.0.1|grep -v inet6|awk '{print $2}'|tr -d "addr:"or
/sbin/ifconfig|sed -n '/inet addr/s/^[^:]*:([0-9.]{7,15}) .*/1/p'
方法二:
local_host="`hostname --fqdn`"local_ip=`host $local_host 2>/dev/null | awk '{print $NF}'`
方法三:
local_host="`hostname --fqdn`"nslookup -sil $local_host 2>/dev/null | grep Address: | sed '1d' | sed 's/Address://g'
