Complete!
 
Installation is completed, now you can reboot the system. 
You should check BBR after the rebooting using command: 
 
     sysctl -a|grep congestion_control

3 安装成功后确认是否生效(显示BBR则成功)

[root@ecs-U9HuM ~]# sysctl -a|grep congestion_control

net.ipv4.tcp_allowed_congestion_control = bbr reno
net.ipv4.tcp_available_congestion_control = bbr reno cubic
net.ipv4.tcp_congestion_control = bbr
sysctl: reading key "net.ipv6.conf.all.stable_secret"
sysctl: reading key "net.ipv6.conf.default.stable_secret"
sysctl: reading key "net.ipv6.conf.eth0.stable_secret"
sysctl: reading key "net.ipv6.conf.eth1.stable_secret"
