环境: 本测试环境为CentOS7_x86_64
方法一:
1,测试网络带宽常用命令(包含安装使用)
yum -y install iperf
2,测试时记得关闭防火墙或者自行配置防火墙规则,为了快速测试,这里就直接关闭防火墙
systemctl stop firewalld
3,安装完iperf后,在Server端执行
iperf -s -i 1 -f m
-s表示server,-i表示显示时间间隔,-f表示显示格式化的单位
4,在Client端执行如下命令
iperf -c 10.241.18.1 -i 1 -t 30 -f m
-c表示客户端,后面接server的地址,-t代表运行的时间
方法二:
使用speedtest-cli命令。
1,安装speedtest-cli
yum –y install python-pip
pip install speedtest-cli
2,测试带宽
三,查看网卡,网络情况
1,使用nload命令查看
yum -y install nload
2, 查看eth0网卡网络情况
nload eth0
Incoming也就是进入网卡的流量,Outgoing,也就是从这块网卡出去的流量,每一部分都有下面几个。
– Curr:当前流量
– Avg:平均流量
– Min:最小流量
– Max:最大流量
– Ttl:总流量
nload默认的是eth0网卡,如果你想监测eth1网卡的流量,可以使用下面的命令
nload -m
3,使用iftop命令查看
yum -y install iftop
4,使用iftop命令测试
iftop
5,使用nethogs命令查看各个进程使用网络的情况
yum -y install nethogs
6,使用nethogs命令查看进程使用网络的情况
nethogs
以上只是个人工作会使用的一些常用的命令,不足之处希望大家多多指点。
