linux环境下添加路由：
查询路由信息：route
route add –net 128.18.0.0 255.255.0.0 MASK gw 128.20.0.0

window   route add 128.18.38.0 mask 255.255.255.0 128.20.1.1
unix     route add -net 128.18.38.0 netmask 255.255.255.0 gw 128.20.1.1

killall -9 httpd
统计进程数：
ps -ef | grep bin/httpd | wc -l

查看达到的并发数：
webbench -c 1000 -t 30 http://ip:8080/index.html

linux增加可执行权限：chmod +x jpda.sh

添加路由:
route print
route add 128.18.0.0 mask 255.255.0.0 128.20.1.1 -p

拷贝数据：
mysqldump -uroot -pAdmin@123 "--where=AREA_ID = 0 AND TYPE = 255" db_name T_TRAFFIC | mysql -uroot -pAdmin@123 -h128.20.20.103 db_name
