安装 Curl 
apt-get update -y && apt-get install curl -y

apt -y install wget
or
yum -y install wget

apt-get install sudo

VPS配置查看：

curl -sL yabs.sh | bash -s -- -i

wget -q https://github.com/Aniverse/A/raw/i/a && bash a

wget -qO- bench.sh | bash

其他

bash <(wget -qO- git.io/ceshi) -j
wget -q https://github.com/Aniverse/A/raw/i/a && bash a

测速：

bash <(curl -Lso- https://git.io/superspeed.sh)

bash <(curl -Lso- http://yun.789888.xyz/speedtest.sh)

流媒体检查：

bash <(curl -L -s check.unlock.media)

bash <(curl -L -s https://raw.githubusercontent.com/lmc999/RegionRestrictionCheck/main/check.sh)

BBR一键脚本

wget -N --no-check-certificate "https://raw.githubusercontent.com/chiakge/Linux-NetSpeed/master/tcp.sh" && chmod +x tcp.sh && ./tcp.sh

BBR手动开启

#首先先更新下系统，然后安装依赖组建：

apt-get update
apt-get update && apt-get install -y wget curl

#之后开启原生BBR：

echo "net.core.default_qdisc=fq" >> /etc/sysctl.conf
echo "net.ipv4.tcp_congestion_control=bbr" >> /etc/sysctl.conf
sysctl -p

#检测是否正常开启BBR：

sysctl net.ipv4.tcp_available_congestion_control
lsmod | grep bbr

回程路由：

curl https://raw.githubusercontent.com/zhanghanyun/backtrace/main/install.sh -sSf | sh

wget https://raw.githubusercontent.com/nanqinlang-script/testrace/master/testrace.sh
bash testrace.sh

wget -qO- git.io/besttrace | bash

宝塔无需手机登录：

echo "{\"uid\":1000,\"username\":\"admin\",\"serverid\":1}" > /www/server/panel/data/userInfo.json

warp 解锁netflix：

硬盘检测

apt-get install smartmontools     
lsblk
smartctl -A /dev/sda | grep Power_On_Hours

硬盘测速

apt install hdparm
hdparm -t --direct /dev/sda

使用dd测试硬盘IO性能
dd if=/dev/zero of=/dd/1Gb.file bs=8k count=102400
dd bs=128k count=10k if=/dev/zero of=test

挂载

lsblk #查看盘符，如添加sdb盘,挂载目录为/dd
mkfs.ext4 /dev/sdb
mkdir /dd
mount /dev/sdb /dd
chmod -R 777 /dd

#取消挂载
umount /dev/sdb

#重启系统后，如发现挂载消失，执行如下两条
mount /dev/sdb /dd 
chmod -R 777 /dd

#多块硬盘组raid0 ,如sdb和sdc两块硬盘
apt-get install mdadm
mdadm -Cv hhd -a yes -n 2 -l 0 /dev/sdb /dev/sdc

#firewall

firewall-cmd --permanent --zone=public --add-masquerade 
firewall-cmd --permanent --zone=public --add-forward-port=proto=8080:proto=tcp:toaddr=192.168.10.10:toport=3000
firewall-cmd --reload
firewall-cmd --zone=public  --list-all

# iptables

iptables -t nat -F
iptables -t nat -A POSTROUTING -j MASQUERADE
iptables -t nat -A PREROUTING -p tcp --dport 8080 -j DNAT --to-destination 192.168.10.10:3000
service iptables save
iptables -t nat -nL --line
