BBR是Google的一套网络拥塞控制算法,用在VPS服务器上,可以有效减少拥堵丢包,明显提高网络连接和某些不可描述的上网速度。文章源自评测啦-https://www.ovz.cc/9.html
因此,不再需要第三方的安装脚本了。直接修改系统配置即可。文章源自评测啦-https://www.ovz.cc/9.html
本文的系统要求为Debian 9或更高版本的Debian Linux,其他操作系统所知不详,不知是否适合本文的方法。文章源自评测啦-https://www.ovz.cc/9.html
请注意,本文的配置参数可以启用Google BBR,还包括多种网络参数的优化,具体的不解释了,直接复制执行使用即可。文章源自评测啦-https://www.ovz.cc/9.html
Google BBR一键加速VPS服务器很简单,SSH登录VPS后,分别执行以下2个命令即可(鼠标单击高亮后,点鼠标右键复制粘贴到根用户的#后面,然后回车)。文章源自评测啦-https://www.ovz.cc/9.html
命令1(比较长,有折行,请完整拷贝):文章源自评测啦-https://www.ovz.cc/9.html
wget -N --no-check-certificate https://raw.githubusercontent.com/veip007/hj/master/hj.sh && chmod +x hj.sh && bash hj.sh
如果提示wget:命令未找到的错误,这是你的系统精简的太干净了,wget都没有安装,所以需要安先装wget:文章源自评测啦-https://www.ovz.cc/9.html
apt-get install -y wgetapt-get install -y wget
命令2:文章源自评测啦-https://www.ovz.cc/9.html
sysctl -p
