贴一下统计服务器并发数统计脚本，根据网上的信息加上自己的需求整理的，把IP换为自己的IP地址即可，统计的是80端口的访问并发适用于Linux平台。 去掉最后的awk段就可以统计当前每个IP的访问数
# echo "当前并发数：`netstat -nt | grep IP:80 | awk ‘{print $5}‘ | awk -F":" ‘{print $1}‘| sort | uniq -c | sort -r -n | awk ‘BEGIN{total=0}{total+=$1}END{print total}‘`";
#统计并发
# echo "当前并发数：`netstat -nt | grep :80 | awk ‘{print $5}‘ | awk -F":" ‘{print $1}‘| sort | uniq -c | sort -r -n | awk ‘BEGIN{total=0}{total+=$1}END{print total}‘`";
统计并发脚本：
# cat Concurrent.sh
#!/bin/bash
while :
