！！！！示例！！！！

比如我是有这两个内核，所以我把这两个删掉，不要照着我的这个步骤做，自己换成你VPS的内核名称！！！

apt-get purge linux-image-3.16.0-4-amd64
apt-get purge linux-image-amd64
开启bbr
modprobe tcp_bbr
echo “tcp_bbr” >> /etc/modules-load.d/modules.conf
echo “net.core.default_qdisc=fq” >> /etc/sysctl.conf
echo “net.ipv4.tcp_congestion_control=bbr” >> /etc/sysctl.conf
执行这个保存生效更改。
sysctl -p
VPS提示：
net.core.default_qdisc = fq
net.ipv4.tcp_congestion_control = bbr
关闭bbr
sed -i ‘/net.core.default_qdisc=fq/d’ /etc/sysctl.conf
sed -i ‘/net.ipv4.tcp_congestion_control=bbr/d’ /etc/sysctl.conf
sysctl -p
执行完上面的代码，就使用reboot重启VPS后才能关闭bbr，重启后再用下面的查看bbr状态代码，查看是否关闭了。
reboot
执行下面命令，看到有 tcp_bbr 模块，即说明bbr已启动
lsmod | grep bbr

安装成功后，进入Google Project建立一个Project
https://console.developers.google.com/project
进入/shaobo/.opam/system/bin/目录绑定项目
cd /shaobo/.opam/system/bin/
./google-drive-ocamlfuse -headless -label googledrive -id ##Client ID##.apps.googleusercontent.com -secret ##secret key## 执行完上述指令会返回一个https的网址在浏览器粘贴到浏览器后会进入google页面询问是否允许访问该项目，选accept然后记录下浏览器页面返回的密码，粘贴进去回车即可。
进入~/.gdfuse/googledrive
cd ~/.gdfuse/googledrive
nano config
编辑config修改内容例如
verification_code= [key returned from browser]
client_id= [eg. 1231232ccc31.apps.googleusercontent.com]
client_secret= [eg. AdddSDQWEWGSD!$@#@#ASD]
