V2RY

BT面板：
yum install -y wget && wget -O install.sh http://download.bt.cn/install/install_6.0.sh && sh install.sh ed8484bec
安装SSL强制HTTPS
网站配置加入：
location /2012 {
proxy_redirect off;
proxy_pass http://127.0.0.1:2012;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
# Show real IP in v2ray access.log
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}

开始安装：
bash <(curl -L https://raw.githubusercontent.com/v2fly/fhs-install-v2ray/master/install-release.sh)
然后解决报错
systemctl start v2ray
systemctl enable v2ray
sed -i "s/v2ray -config/v2ray run -config/g" /etc/systemd/system/v2ray.service.d/10-donot_touch_single_conf.conf
systemctl daemon-reload
systemctl restart v2ray
systemctl status v2ray

编辑配置：
vi /usr/local/etc/v2ray/config.json

"log": {
"loglevel": "info",
"access": "/var/log/v2ray/access.log",
"error": "/var/log/v2ray/error.log"

安装BBR
原文地址：
https://www.vultr.com/zh/docs/how-to-deploy-google-bbr-on-centos-7/
代码：
sudo rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
sudo rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm
sudo yum --enablerepo=elrepo-kernel install kernel-ml -y
rpm -qa | grep kernel
如果成果能看到5.19版本核心
查看排序：sudo egrep ^menuentry /etc/grub2.cfg | cut -f 2 -d \'

# 若出现 “grep: /etc/grub2.cfg: No such file or directory” 的错误， # 运行以下命令解决：

grub2-mkconfig -o /boot/grub2/grub.cfg # 再次运行刚才的命令

如果排第一 设置5.19启动顺序是0还是1，重启：
sudo grub2-set-default 0
sudo shutdown -r now
重启后查看是否成功
uname -r
配置BBR
echo 'net.core.default_qdisc=fq' | sudo tee -a /etc/sysctl.conf
echo 'net.ipv4.tcp_congestion_control=bbr' | sudo tee -a /etc/sysctl.conf
sudo sysctl -p
确认是否成功
lsmod | grep bbr

防火墙
