-c代表为客户端, -u代表udp测试,用于网络抖动测试,输出结果中的Jitter则代表网络抖动的结果。

可能遇到的问题

如果网络连接不了,可能是因为防火墙的原因,centos下的防火墙的常见命令:

firewall-cmd --zone=public --add-port=5672/tcp --permanent   # 开放5672端口

firewall-cmd --zone=public --remove-port=5672/tcp --permanent  #关闭5672端口

firewall-cmd --reload   # 配置立即生效

firewall-cmd --zone=public --list-ports # 查看防火墙所有开放的端口

firewall-cmd --state # 查看防火墙状态

systemctl stop firewalld.service # 关闭防火墙
