一健安装，然后用后面命令又重新搞还是一样.

BBR需要系统内核支持，那个一键包有帮你更换内核吗？

参考我之前写的《【更新】跟风用Ultravps玩了一下BBR，附CentOS 6/7配置过程》

1. sysctl net.ipv4.tcp_congestion_control=bbr
   
2. sysctl net.core.default_qdisc=fq

复制代码

执行完就表示内核支持，不然不支持
然后把

1. net.ipv4.tcp_congestion_control = bbr
   
2. net.core.default_qdisc = fq
   

复制代码

放到/etc/sysctl.conf里面
就行了
